How to check Android for viruses through a computer

Checking Android for viruses through a computer

Some of the users of the most common operating system for mobile devices today - Android, are thinking about the possibility of checking their smartphone or tablet for viruses using the functions of specialized software for Windows. The following resource provides instructions on how to do this.

Despite the widespread prevalence and effectiveness of antiviruses for the Android OS, using a PC to check your mobile device seems to many to be more reliable, and sometimes the only possible method of getting rid of malicious software. It should be noted that such a belief is erroneous, and if you suspect that your smartphone / tablet is infected, it is still better to use Android applications that detect and eliminate viruses.

How to check Android for viruses through a computer

The computer should be used if it is impossible to install / run anti-virus Android applications on a mobile device, or as an additional tool for eliminating threats in the environment of the operating system in question.

Checking Android devices for viruses from a PC

As you know, many modern smartphones and tablets running Android are equipped with a memory card slot. Thus, conditionally, the procedure for scanning mobile devices for viruses using a computer can be divided into two stages: scanning an external removable drive and analyzing the contents of the device's internal memory.

Option 1: Removable storage

Those owners of Android devices who often use them as a means of transferring files and folders from one computer to another may well copy one of the viruses designed to infect Windows (most often "Autorun" and the like). If there is a suspicion of the presence of harmful software on a removable media of a smartphone or tablet, we do the following:

Checking removable storage devices of Android devices for viruses via a computer

  1. We remove the memory card from the slot of the Android device. We put it in a card reader connected to a PC.

    Attempts to connect a mobile device to a computer in order to use it as a card reader to solve the problem of scanning a removable drive for viruses are pointless, to achieve the desired result you need a memory card reader that can be connected to a PC via USB or built into a computer / laptop case!

  2. Card reader for connecting a memory card from an Android device to a computer

  3. We follow one of the instructions available in the material at the following link, that is, we scan the removable drive of an Android device using any antivirus software for Windows, like a regular USB flash drive.

Option 2: Internal memory

If you want or need to scan the internal memory of an Android device for harmful software, you should use specialized software equipped with a module designed specifically for the implementation of this goal. It should be noted that none of the well-known antiviruses for Windows provides the function of scanning mobile devices connected to a PC.

Antivirus program Quick Heal Total Security with the function of scanning mobile devices connected to a PC via USB

Despite the above, there is still a toolkit that allows you to analyze the storage of a phone or tablet from a computer and identify viruses if any. We use a little-known, but judging by the reviews, a rather effective tool - Quick Heal Total Security , or rather, the module integrated into this anti-virus complex "PC2Mobile Scan" .

Download the Quick Heal Total Security application with a module for scanning mobile devices from the official website

The program is distributed on a paid basis, but the user is provided with a 30-day trial period, which is quite enough to resolve the issue from the title of the article.

  1. Download and install Quick Heal Total Security on your computer or laptop:
  2. We launch and activate the antivirus.
  3. We scan the Android device for viruses:

Conclusion

In conclusion, once again, we note the very mediocre efficiency of the procedure for scanning mobile devices for viruses using a computer. We recommend using specialized Android applications that are produced by most well-known antivirus software developers and are available in abundance on the Google Play Store to detect and remove malicious software on smartphones and tablets.

Checking Android for viruses through a computer

How to check android for viruses

The number of malicious applications and files for Android OS is growing every year. And scammers and hackers come up with more sophisticated ways to steal money and personal information from the phone. Therefore, it is important to prepare and know how to check an android for viruses.

Ways to check an android phone for viruses

There are four methods for diagnosing a mobile device for viruses:

  • Mobile antivirus software.
  • Using a computer.
  • Online check.
  • Google Play Protect.

Method 1: Mobile Antivirus

Checking with mobile antiviruses is the simplest method available to every owner of an Android phone or tablet and does not require a PC. For verification, Android applications are used that work on the same principle as on desktop versions of the OS. Mobile antiviruses allow you to detect and remove installed applications with malicious code, report existing vulnerabilities, unwanted actions or files.

Instructions for checking:

  1. Download and install the anti-virus application. To do this, follow the link https://androfon.ru/antivirus-android , where popular and demanded anti-virus utilities are collected. Or go to the Google Play app store and search for "antivirus".
  2. Launch antivirus software and scan for threats. To do this, you need to update the signatures - the database.
  3. If necessary, configure the utility for in-depth analysis. This will increase the scan duration, but increase the likelihood of detecting threats.
  4. Wait until the end of the scan, make a decision if viruses are detected: delete, disinfect, quarantine, etc.

Important!

For reliability, it is recommended to install and scan your android phone with several antiviruses.

Before installing a new utility, you must remove the previous program to avoid conflicts in the system.

Most antiviruses are distributed under a paid license, with developers often providing a 1-4 week trial version for free. Do not neglect a trial license, as this will allow you to take full advantage of the antivirus.

Before installing the antivirus, it is advisable to visit an independent organization AV-TEST specializing in testing security software.

When downloading an antivirus program through Google Play, it is worth comparing the name of the utility and the developer. Often, attackers download fake apps with a similar name.

Below is an overview and comparison of popular antivirus applications.

Method 2: Using a computer

The method is similar to the previous one, only instead of a mobile antivirus, a desktop version designed for a PC is used to scan an android phone for viruses. This type of diagnostics allows you to identify hidden threats missed by the mobile version. Detect unwanted files, as well as check programs downloaded from outside the official app stores.

Instructions on how to check an android phone for viruses via a computer:

  1. It is required to connect the device to a computer with an anti-virus program installed. Otherwise, you need to download and install the utility. To do this, use only official resources.
  2. In the phone connection settings, specify MTP (Media Transfer Protocol). This is necessary to display the device's memory in the form of removable disks.

Often, the Android system prompts you to select the type of connection when pairing the device with a PC. If this does not happen, you need to activate the item manually. This is usually done in the "memory" section of the settings section, sometimes in the "for developers" section. To get into the last one, you need to click 7 times on the build number in the item "about the phone".

  1. After displaying the internal and / or external memory, it is necessary to scan one by one. To do this, highlight the disk, right-click and select the item associated with scanning from the context menu.
  2. Wait until the end of the operation and delete the found malicious files.

Method 3: Online check

Many users prefer to download programs from third-party or pirated app stores. This often results in a virus being installed disguised as a normal program. Therefore, before installing, it is rational to check the file with a cloud antivirus or an online scanner. The service will analyze the contents of the installation apk-file and compare the data with the known virus databases. Such services will come in handy for users with no access to a computer or in the absence of a desire to contact mobile antivirus software.

Instructions for online check:

  1. We find a service to check. Let's use the free service as an example. virustotal .
  2. Download the application you like. For example, we will use one of the antiviruses in our catalog - G Data Internet Security Light, available here. https://androfon.ru/antivirus-android/g-data-internet-security-light
  3. On the virustotal page, the "file" tab, indicate the location of the installation application. This action is available from both a PC and a mobile device.
  4. If the file exceeds 128 MB, you should provide a direct link to the application in the adjacent "URL" tab.
  5. We are waiting for the results of the analysis, making sure that the application is safe, and then installing it on a mobile device.

Method 4: Google Play Protect

Andro OS> AV-Test. At the same time, the system is regularly improved, and with it the benefits.

Google Play Protect runs in the background. If the Internet is available, installed applications are checked once a day. A similar check is performed when installing the program via Google Play. If malicious code is found, the installation will stop. In practice, this is rare or not at all.

To use Google Play Protect, you just need to add a Google account to your mobile device. Then go to the app store. Call the hidden panel on the left and select the "Play protection" item. A new window will display information about the current state of the device.

Free online antiviruses to check files on your phone and computer

If you are tired of installing and uninstalling antiviruses, downloading antivirus databases and activating keys, refer to online antiviruses. Scanning files for viruses without installation is quite a worthy alternative to traditional scanners.

We have selected half a dozen reliable, free and effective antivirus scanners that work online - that is, through a browser. Thus, you can find out if there is a virus on your phone without downloading third-party programs.

Which web service should you choose for a one-time check? Is online antivirus suitable for Android? Read about all this in our review.

List of online antiviruses:

ESET Online Scanner - online file virus scan

Antivirus scan service from ESET is a comprehensive and effective antivirus. It works from a browser, scanning files and does not require installation on a computer.

How to scan a file for viruses in ESET Online, video tutorial:

Unlike the desktop version of ESET Nod, this web antivirus is free to use. Do not think that it makes no sense to demand a full-fledged scanner from a web application. According to the creators, the online antivirus successfully copes with Trojans, the latest viruses, worms, and phishing threats.

The user can select files on the computer disk for scanning, specify memory areas, etc. Moreover, you do not need to have administrator rights to run an online check.

At the end of the search, ESET Online Scanner offers to remove the detected viruses or quarantine infected files.

In general, cleaning from viruses with ESET Online Scanner's web antivirus makes sense in many cases. In particular, if you want to scan someone else's computer, check the flash drive for malicious files online, but you do not have the right (or desire) to install applications.

Powerful online scanner Doctor Web

This service is designed to check links for safety. Insert a link to a suspicious site into a special text field, and Doctor Web scans the attached files on the html page, examining whether there is any malicious code. As a rule, a virus threat on online resources is hidden in javascript files. If the scripts are contained in the database of malicious sites or the site redirects to another resource, Doctor Web Online will notify you of this.

As you can see, the service is very minimalistic, there is only an antivirus web shell, which is not very convenient. It would be great if Doctor Web had acquired, say, an android application for online checking, or, ideally, a browser add-on. At this point, we would not recommend the online version of the antivirus for use on a phone.

Tip of the day ... By the way, if you need a good free antivirus to scan your computer (or memory card / flash drive) for viruses, without downloading additional applications, we recommend downloading the Doctor Web curing utility. It uses the current databases of the desktop version of Doctor Web, while the functional part is minimized.

VirusTotal - total online scanning of files for viruses

VirusTotal is another free service that checks for viruses online. It scans the contents of files and the code of sites on the Internet. VirusTotal scans any suspicious content for worms, malware, Trojans and other types of pests and virus threats, and helps to check Android for viruses.

Video how to use the service:

VirusTotal also allows you to search for threats in comments that users post on files and URLs, check passive DNS data, and extract threat information about domains and IP addresses.

VirusTotal stores all analyzes in its database. It enables users to search reports with MD5, SHA1, SHA256 data. The search results return the last crawl performed on the resource you are interested in.

Kaspersky Online Scanner (VirusDesk)

Online service from the creators of Kaspersky Anti-Virus for Android. Checks files and links on the Internet and does not require the installation of additional modules. When downloading a file, Kaspersky scans it in its databases for existing threats and gives the result. This checks md5, SHA1 and SHA256 hashes. All databases are regularly updated, as evidenced by the corresponding inscription above the field for downloading files.

The result of the scan may be negative, in which case VirusDesk gives the status: the file is infected or suspicious.

Important! Unlike conventional antiviruses, you can only scan a file for viruses, but you will not be able to quarantine or automatically delete it - you can only do this manually.

This online antivirus is also suitable for checking your phone for viruses. You can upload files up to 50 MB, batch mode is not supported. The scanner does not remove viruses - the user must perform this action on his own. At the same time, for performing a single scan, Kaspersky VirusDesk can become such a one-time antivirus, which is also not bad.

VirSCAN - online antivirus for Android

Through the VirSCAN.org service, it is possible to scan Android for viruses online, as well as online scan files for malicious code.

For example, you can send apk-applications or other files for testing (the size should not exceed 20 MB). These can be zip and rar archives or with password protection (only ‘infected’ and ‘virus’ passwords can be set).

The main and most significant feature of the VirSCAN online antivirus is a huge database of regularly updated scanners, including kaspersky, avg, drweb, symantec and others. Among other things, VirSCAN verifies MD5 and SHA1 hashes against its databases.

As the authors of this web antivirus warn, sometimes false alarms can be triggered, which is not surprising with such an impressive list of antivirus software. But, as they say, it is better to interrupt than not to interrupt!

The downside of this online checking mechanism is the slow speed of operation, the absence of any settings (which would speed up the process) and the lack of scanning options: only single files can be loaded for virus scanning.

AVC UnDroid - service for checking apk files

Free online service AVC UnDroid is designed to search for viruses in the contents of apk-files. It uses engines such as Buster Sandbox Analyzer, ssdeep, and APKTool for scanning.

In order to check apk for viruses, press the Select APK ... button and download the installer file to check on your phone. AVC UnDroid supports data up to 7MB, which is sufficient for most tasks.

The downloaded files are analyzed inside AVC UnDroid, after which the user receives a detailed scan report - file hashes, security assessment and additional information.

Other data types are not supported, you can only upload one file at a time.

For convenience, you can register. This opens access to statistics and comments, increases the limit on uploaded files and increases the priority.

As stated in the terms of use, this online checkout service is experimental. The downloaded apk-files, their contents can be used by the service, and there is nothing wrong with that.

How to check Android for viruses through a computer

An Android phone or tablet has certain similarities to a Windows computer, so viruses can also get on it. Antiviruses for Android have been developed specifically for these purposes.

But what if there is no way to download such an antivirus? Can I check my device using antivirus on my computer?

How to check Android for viruses through a computer

Content How to check Android for viruses through a computer

Android check via computer

Many antiviruses for computers have a built-in function for checking connected media. Considering that the computer sees the Android device as a separate plug-in device, then this check option is the only possible one.

It is worth considering the peculiarities of antiviruses for computers, the operation of Android and its file system, as well as some mobile viruses. For example, a mobile OS can block anti-virus access to many system files, which seriously affects the scan results.

You should only check Android through your computer if there are no other options available.

Method 1: Avast

Avast is one of the most popular antivirus programs in the world. There are paid and free versions. To scan an Android device through a computer, the functionality of the free version is quite enough.

Method instruction:

1. Open the antivirus program. In the left menu, you need to click on the item " Protection ". Next select " Antivirus ".

2. A window will appear where you will be offered several options for scanning. Select " Other scan ".

3. To start scanning a tablet or phone connected to a computer via USB, click on " Scanning USB / DVD ". The antivirus will automatically start scanning all USB drives connected to the PC, including Android devices.

4. At the end of the scan, all dangerous objects will be deleted or placed in the " Quarantine ". A list of potentially dangerous objects will be displayed, where you can decide what to do with them (delete, send to " Quarantine ", nothing to do).

However, if you have some kind of protection on your device, then this method may not work, since Avast will not be able to access the device.

The scanning process can be started in another way:

1. Find in " Explorer »Your device. It can be referred to as a separate removable medium (for example, "Drive F"). Right click on it.

2. From the context menu, select the option " Scan ". Along with the caption there should be an Avast icon.

Avast has an automatic scan for USB drives. Perhaps even at this stage, the software will be able to detect a virus on your device, without starting an additional scan.

Method 2: Kaspersky Anti-Virus

Kaspersky Anti-Virus is a powerful anti-virus software from domestic developers. Previously, it was completely paid, but now there is a free version with reduced functionality - Kaspersky Free. It doesn't matter if you're using the paid or free version, both have the functionality you need to scan Android devices.

Let's consider the process of setting up a scan in more detail:

1. Launch the antivirus user interface. There select the element " Check ".

2. In the left menu, go to " Checking external devices ". In the central part of the window, select the letter from the drop-down list, which was designated your device when connected to a computer.

3. Click " Run check ".

4. Verification will take some time. Upon completion, you will be presented with a list of detected and potential threats. With the help of special buttons you can get rid of dangerous elements.

Similarly with Avast, you can run a scan without opening the antivirus user interface. Just search in " Explorer "The device to be scanned, right-click on it and select the option" Scan ". There should be a Kaspersky icon opposite it.

Method 3: Malwarebytes

It is a dedicated utility for detecting spyware, adware and other malware. Despite the fact that Malwarebytes is less popular with users than the antiviruses discussed above, it sometimes turns out to be more effective than the latter.

The instructions for working with this utility are as follows:

1. Download, install and run the utility. In the user interface, open the item " Check », Which is in the left menu.

2. In the section where you are asked to select the type of check, indicate “ Selective ".

3. Click on the " Customize Scan ".

4. First, configure the scan objects in the left part of the window. Here it is recommended to check the boxes above all items except “ Checking for rootkits ".

5. In the right part of the window, check the box for the device you want to check. Most likely, it will be designated by some letter like an ordinary USB flash drive. Less commonly, it may bear the name of the device model.

6. Click " Run check ".

7. When the scan is completed, you will be able to see a list of files that the program considers potentially dangerous. From this list, they can be placed in " Quarantine ", And from there it is already completely removed.

It is possible to start scanning directly from " Explorer "By analogy with the antiviruses discussed above.

Method 4: Windows Defender

This antivirus program is included by default in all modern versions of Windows. Its latest versions have learned to identify and fight most of the known viruses on a par with their competitors such as Kaspersky or Avast.

Let's take a look at how to scan Android devices for viruses using the standard Defender:

1. First, open the Defender. In Windows 10, this can be done using the system search bar (invoked by clicking on the magnifying glass icon). It is noteworthy that in the new editions of dozens of the Defender was renamed to “ Windows Security Center ".

2. Now click on any of the shield icons.

3. Click on the inscription “ Extended validation ".

4. Set the marker to " Custom scan ".

5. Click " Scan now ".

6. In the opened " Explorer "Select your device and click" OK ".

7. Wait for the check to complete. Upon completion, you can delete, or put in " Quarantine »All found viruses. However, some of the detected items may not be able to be removed due to the peculiarities of the Android OS.

It is quite possible to scan an Android device using the capabilities of a computer, but there is a possibility that the result will be inaccurate, so it is best to use antivirus software designed specifically for mobile devices.

Checking Andro>

The computer should be used if it is impossible to install / run anti-virus Android applications on a mobile device, or as an additional tool for eliminating threats in the environment of the operating system in question.

Checking Android devices for viruses from a PC

As you know, many modern smartphones and tablets running Android are equipped with a memory card slot. Thus, conditionally, the procedure for scanning mobile devices for viruses using a computer can be divided into two stages: scanning an external removable drive and analyzing the contents of the device's internal memory.

Option 1: Removable storage

Those owners of Android devices who often use them as a means of transferring files and folders from one computer to another may well copy one of the viruses designed to infect Windows (most often "Autorun" and the like). If there is a suspicion of the presence of harmful software on a removable media of a smartphone or tablet, we do the following:

    We remove the memory card from the slot of the Android device. We put it in a card reader connected to a PC.

Attempts to connect a mobile device to a computer in order to use it as a card reader to solve the problem of scanning a removable drive for viruses are pointless, to achieve the desired result you need a memory card reader that can be connected to a PC via USB or built into a computer / laptop case!

Option 2: Internal memory

If you want or need to scan the internal memory of an Android device for harmful software, you should use specialized software equipped with a module designed specifically for the implementation of this goal. It should be noted that none of the well-known antiviruses for Windows provides the function of scanning mobile devices connected to a PC.

Despite the above, there is still a toolkit that allows you to analyze the storage of a phone or tablet from a computer and identify viruses if any. We use a little-known, but judging by the reviews, a rather effective tool - Quick Heal Total Security , or rather, the module integrated into this anti-virus complex "PC2Mobile Scan" .

The program is distributed on a paid basis, but the user is provided with a 30-day trial period, which is quite enough to resolve the issue from the title of the article.

    Download and install Quick Heal Total Security on your computer or laptop:
    We temporarily disable the antiviruses and firewalls available in the system from third-party developers. Windows Defender you do not need to deactivate it, it does not interfere with the installation of software from Quick Heal.

    We follow the link located in front of this instruction.

    Scroll down the web page until the list of products offered by the developer is displayed, and click on the link under the name "Quick Heal Total Security" .

    Push the button "Download" under the description of the system requirements for the software.

    Specify the path to save the distribution, click "Save" .

    Waiting for the file upload to complete QHTSFT.EXE , follow the path where it is saved and run the installer.

    In the window that opens, specify the path where the files necessary for installing the antivirus will be placed, and click "Download" .

    We are waiting for the download of the components necessary for the Quick Heal Total Security installer to complete.

    As soon as everything you need is downloaded, it will start "Installation Wizard" antivirus complex.

    We set the marks in two checkboxes under "License Agreement" and click "Next" .

    Optionally, indicate the path on the PC disk where the software will be installed using the button Browse ... Click "Next" .

    We are waiting for the installer to complete.

    At the end of the installation, click Register Later in the final window of the Wizard.

We launch and activate the antivirus.

    Open the application, for example, by clicking on the Quick Heal Total Security icon on the Windows Desktop.

    Click "Activate Now" in the red area of ​​the main application window.

    Click "Next" In the first

    and the second windows of the launched Registration Wizards .

    Filling in the window fields "User Information" (reliability "Contact Number" and addresses are not checked, you can enter any values). Click "Next"

    twice. Click "Finish" in the window "Activation successfully completed" , after which we can proceed to the full use of the antivirus from Quick Heal.

We scan the Android device for viruses:

    In the main window of Quick Hel Total Security, click "Scan" .

    In the context menu that appears, select "Mobile Scan" .

    We connect the running Android device to the computer using a USB cable.

    As "USB connection mode" on the mobile device choose "File Transfer" .

    In the window "Mobile Scan" antivirus software click Search Mobile , and then "Start Search" in the request window.

    We are waiting for the device to be identified in the application.

    Click on the name of the device in the field "Select Mobile device ..." and then click "Start Scan" .

    We are waiting for the completion of the memory scan of the Android device. The process is visualized using a progress bar in the Quick Heal Total Security window. The time spent on analysis depends on the amount of storage on the mobile device.

    When the antivirus completes its work, a window with the results is displayed, which should be closed if there are no detected threats. This completes the task of checking an Android device for viruses using a computer or laptop.

  • In the program settings (consider the procedure for removing a virus using the example of ESET Smart Security), open the "PC scan" tab -> "Removable media".
  • Click "All disks", thereby starting the check.

    Cleaning a mobile device through a computer from virus programs and banners

    This type of malware is installed on smartphones (tablets) as separate applications and usually leads to the appearance of advertising banners on the screen. This not only prevents the owner from using the device normally, but also causes severe braking and periodic freezes. Such a virus can get on the phone when installing programs from third-party sites, since all software posted on the Play Market is checked for malicious code by the built-in Bouncer scanner.

    The first thing to do when jumping onto the screen of advertising banners is to examine the "Applications" section and, if a suspicious program is found, completely remove it.

    If the malicious object is not erased or reappears when the mobile phone is restarted, we try to use the Android Commander utility. It opens access to the internal and external storage of the smartphone and allows you to manually remove the infected program through your computer. For its normal operation, you will need Superuser rights. They can be obtained using the Kingo Root:

    1. Install the application on your PC.
    2. We connect a mobile device to it and activate USB debugging.
    3. Launch Kingo Root and click Root in the window that appears, thereby starting the rooting procedure.

    After the superuser profile is open, you can proceed directly to the treatment of the gadget:

    1. We connect the smartphone to the computer, and then scan its external and internal memory with the available antivirus program.
    2. If the check does not give a positive result, install and run the Andro program />

    After searching for and removing the virus through a computer, the smartphone should regain its previous performance. In order to exclude infection of the device in the future, uncheck the box next to the item “Unknown sources” in its settings (section “Security”). This will prevent the installation of software from third-party sites.

    How to check an Android phone for viruses through a computer

    Modern smartphones are at risk of virus programs on them. They can add intrusive advertising banners and try to steal the owner's personal data (passwords, phone numbers, card numbers, etc.). It is for this reason that the owners of such gadgets want to check the android for viruses through a computer. There are many ways to protect your device, but professional PC software does the best.

    Smartphone check via computer

    It is quite difficult to infect your phone with any virus software. This is due to the fact that Android devices are initially equipped with serious security measures. It doesn't matter what model the smartphone will be - Lenovo, Samsung or any other. It will definitely come with security software.

    Such built-in defenders are capable of interrupting the installation of malicious applications and stopping the activities of phishing (data-stealing) programs without the participation of the owner. And when visiting dangerous pages, the system will show the user a warning that this site and its contents may harm the device and the information stored on it.

    If, nevertheless, a viral application somehow got on the smartphone, do not despair. Most often, it will be enough to scan the entire device with an ordinary antivirus application for a PC.

    The most serious problems are considered to be spyware, which can collect and transmit data to a programmed server without the user's knowledge. They are called Trojans. Many computer users are familiar with them. The first sign of such viruses is a decrease in device performance and an increase in mobile traffic consumption. If this happens, then it's time to check your phone for viruses.

    It is very easy to get rid of lurking malware with the help of a computer antivirus. You just need to install it and follow these steps :

    1. Connect your smartphone to your computer via a USB cable.
    2. Run an anti-virus program on the computer.
    3. In the program settings, you need to run a removable media check (the location of this function depends on the specific program).
    4. A scan will begin, after which it will be necessary to remove malicious objects.

    The spy software developed for Android is not that perfect. Therefore, the antivirus can easily cope with its detection and elimination. After all, PC apps are designed to deal with more serious threats.

    But Trojans are not the only smartphone threat. There are so-called viral banner ads. Their goal is to display intrusive ads, a random click on which can trigger various processes. From visiting a malicious website to running an algorithm to collect data from a device.

    The main feature is the presence of advertisements in browser windows and basic applications that were not there before. The main source of such harmful and intrusive software is programs from unverified sources. After all, none of the applications on Google Play are released without checking for malicious elements.

    Banner apps can be removed in the same way as hidden software. However, there are times when this does not work. Virus software remains on the phone even after cleaning and rebooting the device. In this case, you will need to obtain Root rights (superuser rights). This is necessary in order to get to the virus, "stuck" in the memory segment inaccessible to a user with normal access rights. You will need two system utilities called Android Commander and Kingo Root. What do we have to do :

    1. The Kingo Root program is installed on the PC.
    2. A smartphone is connected to the computer.
    3. In the program on the PC, the "Root" button is pressed.

    These actions will help the owner gain access to the protected sectors of the device's memory. After that, you can proceed to the treatment of the smartphone. :

    1. Scan the internal and external memory of the gadget through the "Media Scan" option in the antivirus.
    2. If the check is successful, all malware must be removed.
    3. If the scan did not find anything, then you need to connect Android Commander to the treatment.
    4. In the interface of this program, you need to find the folder with the malicious file and delete the virus body itself.
    5. Be sure to then delete the residual contents of the virus software from the Data folder.

    It is not difficult to find these sources of infection - most often they differ in name from other files on the system partitions. You can also calculate them by the installation date.

    The first sign of successful treatment is the return of device performance. Absolutely anyone can choose an antivirus to scan the phone through a computer - everyone has the function of scanning external media.

    Online Antivirus for Android

    In order not to spend a lot of time installing and configuring the necessary antivirus software, you can use their online counterparts. This saves a lot of time and effort. Their functionality is practically the same as the versions for installation on a PC and laptop. The only thing that can limit their use is a line of other people who want to check their PC or smartphone for viruses. But this problem can be solved by simply registering with the service.

To provide full protection and forget about checking your smartphone for viruses through a computer forever, you need to use mobile antivirus software.

    They provide 24/7 protection against all kinds of threats ... Not only from viral ones: for example, from the currently popular "miners" who use the resources of the device for their needs. The presence of such a program will also help to preserve the confidentiality of many data. You can enter passwords in the local database, and the system will automatically warn you when they are entered on an unverified and dangerous site.

    Not without its drawbacks. Many of the applications do not support Russian, as they are developed by foreign companies. And also most often they are distributed by paid subscription or have built-in (verified and safe) ads.

    Avast Mobile Security

    Avast is an international veteran in the antivirus software industry. Nobody was surprised when the mobile version of the popular and effective antivirus appeared. Despite the fact that this application is free, its functionality is enormous.

    Avast can block unwanted calls, protect against spam ... The most notable feature is the anti-theft function. In case of loss or theft of the phone, the owner can activate it from another device, and all data on the lost gadget will be erased or preserved with the impossibility of hacking.

    Another useful feature of this antivirus is application blocking mode ... That is, the user will be able to set a password for any application he uses, for example, a messenger or Internet bank. This will prevent malicious software from accessing this data.

Also in it there is an analog of the function "anti-theft », Which includes alarm for a smartphone, tracking its location, blocking access and erasing data.

    This antivirus is distributed on a paid subscription, but users can test the entire functionality of the program in a ten-day trial mode.

    The Kaspersky brand is very popular on the territory of Russia, since the software of this company is created by domestic developers. Users expect a high-quality and free product that does not have ads.

    He very highly rated by users all over the country and abroad, as well as the main PC antivirus. Like its “big brother”, the mobile antivirus neutralizes both existing threats and those that are just trying to get into the phone's memory.

    Kaspersky for smartphone has some special functions, in addition to the usual anti-virus capabilities of searching and deleting dangerous files and applications. But most of them are only available in the paid version. However, do not despair, because the basic functionality is more than enough to ensure high-quality protection of the device from any threats.

How to check Android for viruses through a computer

An Android phone or tablet has certain similarities to a Windows computer, so viruses can also get on it. Antiviruses for Android have been developed specifically for these purposes.

But what if there is no way to download such an antivirus? Can I check my device using antivirus on my computer?

Content - How to check Android for viruses through a computer

Android check via computer

Many antiviruses for computers have a built-in function for checking connected media. Considering that the computer sees the Android device as a separate plug-in device, then this check option is the only possible one.

It is worth considering the peculiarities of antiviruses for computers, the operation of Android and its file system, as well as some mobile viruses. For example, a mobile OS can block anti-virus access to many system files, which seriously affects the scan results.

You should only check Android through your computer if there are no other options available.

Method 1: Avast

Avast Is one of the most popular antivirus programs in the world. There are paid and free versions. To scan an Android device through a computer, the functionality of the free version is quite enough.

Method instruction:

1. Open the antivirus program. In the left menu, you need to click on the item " Protection ". Next select " Antivirus ".

Avast

2. A window will appear where you will be offered several options for scanning. Select " Other scan ".

Avast

3. To start scanning a tablet or phone connected to a computer via USB, click on " Scanning USB / DVD ". The antivirus will automatically start scanning all USB drives connected to the PC, including Android devices.

Avast

4. At the end of the scan, all dangerous objects will be deleted or placed in the " Quarantine ". A list of potentially dangerous objects will be displayed, where you can decide what to do with them (delete, send to " Quarantine ", nothing to do).

However, if you have some kind of protection on your device, then this method may not work, since Avast will not be able to access the device.

The scanning process can be started in another way:

1. Find in " Explorer »Your device. It can be referred to as a separate removable medium (for example, "Drive F"). Right click on it.

2. From the context menu, select the option " Scan ". Along with the caption there should be an Avast icon.

Scan

Avast has an automatic scan for USB drives. Perhaps even at this stage, the software will be able to detect a virus on your device, without starting an additional scan.

Method 2: Kaspersky Anti-Virus

Kaspersky Anti-Virus - powerful antivirus software from domestic developers. Previously it was completely paid, but now there is a free version with reduced functionality - Kaspersky Free ... It doesn't matter if you're using the paid or free version, both have the functionality you need to scan Android devices.

Let's consider the process of setting up a scan in more detail:

1. Launch the antivirus user interface. There select the element " Check ".

Kaspersky Anti-Virus

2. In the left menu, go to " Checking external devices ". In the central part of the window, select the letter from the drop-down list, which was designated your device when connected to a computer.

3. Click " Run check ".

Kaspersky Anti-Virus

4. Verification will take some time. Upon completion, you will be presented with a list of detected and potential threats. With the help of special buttons you can get rid of dangerous elements.

Similarly with Avast, you can run a scan without opening the antivirus user interface. Just search in " Explorer "The device to be scanned, right-click on it and select" Scan ". There should be a Kaspersky icon opposite it.

Check for viruses

Method 3: Malwarebytes

It is a dedicated utility for detecting spyware, adware and other malware. Though Malwarebytes is less popular with users than the antiviruses discussed above, it sometimes turns out to be more effective than the latter.

The instructions for working with this utility are as follows:

1. Download, install and run the utility. In the user interface, open the item " Check », Which is in the left menu.

2. In the section where you are asked to select the type of check, indicate “ Selective ".

3. Click on the " Customize Scan ".

Malwarebytes

4. First, configure the scan objects in the left part of the window. Here it is recommended to check the boxes above all items except “ Checking for rootkits ".

5. In the right part of the window, check the box for the device you want to check. Most likely, it will be designated by some letter like an ordinary USB flash drive. Less commonly, it may bear the name of the device model.

6. Click " Run check ".

Malwarebytes

7. When the scan is completed, you will be able to see a list of files that the program considers potentially dangerous. From this list, they can be placed in " Quarantine ", And from there it is already completely removed.

It is possible to start scanning directly from " Explorer "By analogy with the antiviruses discussed above.

Malwarebytes

Method 4: Windows Defender

This antivirus program is included by default in all modern versions of Windows. Its latest versions have learned to identify and fight most of the known viruses on a par with their competitors such as Kaspersky or Avast.

Let's take a look at how to scan Android devices for viruses using the standard Defender:

1. First, open the Defender. In Windows 10, this can be done using the system search bar (invoked by clicking on the magnifying glass icon). It is noteworthy that in the new editions of dozens of the Defender was renamed to “ Windows Security Center ".

Windows defender

2. Now click on any of the shield icons.

Windows defender

3. Click on the inscription “ Extended validation ".

Windows defender

4. Set the marker to " Custom scan ".

5. Click " Scan now ".

Windows defender

6. In the opened " Explorer "Select your device and click" OK ".

7. Wait for the check to complete. Upon completion, you can delete, or put in " Quarantine »All found viruses. However, some of the detected items may not be able to be removed due to the peculiarities of the Android OS.

It is quite possible to scan an Android device using the capabilities of a computer, but there is a possibility that the result will be inaccurate, so it is best to use antivirus software designed specifically for mobile devices.

How to check android for viruses? 4 ways to check your Android phone for viruses

Checking Android for viruses through a computer

Alexander Moiseenko /: 04/11/2018 / Last update: 08/27/2018

The number of malicious applications and files for Android OS is growing every year. And scammers and hackers come up with more sophisticated ways to steal money and personal information from the phone. Therefore, it is important to prepare and know how to check an android for viruses.

There are four methods for diagnosing a mobile device for viruses:

  • Mobile antivirus software.
  • Using a computer.
  • Online check.
  • Google Play Protect.

Method 1: Mobile Antivirus

Checking with mobile antiviruses is the simplest method available to every owner of an Android phone or tablet and does not require a PC.

For verification, Android applications are used that work on the same principle as on desktop versions of the OS.

Mobile antiviruses allow you to detect and remove installed applications with malicious code, report existing vulnerabilities, unwanted actions or files.

Instructions for checking:

  1. Download and install the anti-virus application. To do this, follow the link https://androfon.ru/antivirus-android , where popular and demanded anti-virus utilities are collected. Or go to the Google Play app store and search for "antivirus".
  2. Launch antivirus software and scan for threats.

    To do this, you need to update the signatures - the database.

  3. If necessary, configure the utility for in-depth analysis. This will increase the scan duration, but increase the likelihood of detecting threats.
  4. Wait until the end of the scan, make a decision if viruses are detected: delete, disinfect, quarantine, etc.

Important!

For reliability, it is recommended to install and scan your android phone with several antiviruses.

Before installing a new utility, you must remove the previous program to avoid conflicts in the system.

Most antiviruses are distributed under a paid license, with developers often providing a 1-4 week trial version for free. Do not neglect a trial license, as this will allow you to take full advantage of the antivirus.

Before installing the antivirus, it is advisable to visit an independent organization AV-TEST specializing in testing security software.

When downloading an antivirus program through Google Play, it is worth comparing the name of the utility and the developer. Often, attackers download fake apps with a similar name.

Below is an overview and comparison of popular antivirus applications.

Method 2: Using a computer

The method is similar to the previous one, only instead of a mobile antivirus, a desktop version designed for a PC is used to scan an android phone for viruses. This type of diagnostics allows you to identify hidden threats missed by the mobile version. Detect unwanted files, as well as check programs downloaded from outside the official app stores.

Instructions on how to check an android phone for viruses via a computer:

  1. It is required to connect the device to a computer with an anti-virus program installed. Otherwise, you need to download and install the utility. To do this, use only official resources.
  2. In the phone connection settings, specify MTP (Media Transfer Protocol). This is necessary to display the device's memory in the form of removable disks.

Often, the Android system prompts you to select the type of connection when pairing the device with a PC. If this does not happen, you need to activate the item manually. This is usually done in the "memory" section of the settings section, sometimes in the "for developers" section. To get into the last one, you need to click 7 times on the build number in the item "about the phone".

  1. After displaying the internal and / or external memory, it is necessary to scan one by one. To do this, highlight the disk, right-click and select the item associated with scanning from the context menu.
  2. Wait until the end of the operation and delete the found malicious files.

Method 3: Online check

Many users prefer to download programs from third-party or pirated app stores. This often results in a virus being installed disguised as a normal program.

Therefore, before installing, it is rational to check the file with a cloud antivirus or an online scanner. The service will analyze the contents of the installation apk-file and compare the data with the known virus databases.

Such services will come in handy for users with no access to a computer or in the absence of a desire to contact mobile antivirus software.

Instructions for online check:

  1. We find a service to check. Let's use the free service as an example. virustotal .
  2. Download the application you like. For example, we will use one of the antiviruses in our catalog - G Data Internet Security Light, available here. https: // androfon.

    ru / antivirus-android / g-data-internet-security-light

  3. On the virustotal page, the "file" tab, indicate the location of the installation application. This action is available from both a PC and a mobile device.
  4. If the file exceeds 128 MB, you should provide a direct link to the application in the adjacent "URL" tab.
  5. We are waiting for the results of the analysis, making sure that the application is safe, and then installing it on a mobile device.

Method 4: Google Play Protect

Android OS has built-in protection against malware - Google Play Protect. This is a passive antivirus, the quality of which leaves much to be desired, which is confirmed by the results. AV-Test ... At the same time, the system is regularly improved, and with it the benefits.

Google Play Protect runs in the background. If the Internet is available, installed applications are checked once a day. A similar check is performed when installing the program via Google Play. If malicious code is found, the installation will stop. In practice, this is rare or not at all.

To use Google Play Protect, you just need to add a Google account to your mobile device. Then go to the app store. Call the hidden panel on the left and select the "Play protection" item. A new window will display information about the current state of the device.

Viruses and malicious files must be removed immediately, and in order to detect them, it is necessary to systematically scan the android device for viruses and malware.

Timely detection and taking appropriate measures will prevent the leakage of personal information, save money on your mobile and bank account.

If viruses are present in system applications and cannot be removed, be sure to contact your dealer or service center to solve the problem.

Check and remove viruses from Android tablet

Checking Android for viruses through a computer

Virus programs have attacked users' devices since the beginning of the development of computer technology. With Windows, virus writers turned their attention to other systems, including Android.

Numerous viruses, from relatively harmless advertising and spam distributors to stealing money from phone, card and wallet accounts, are written every day, and today they take such forms that at first glance it is impossible to even distinguish the interface of a malicious program from your own account.

With the widespread introduction of SMS banking, it is not surprising that user passwords from personal accounts have become a frequent target of "invaders".

Search and eliminate viruses on Android tablet.

Regardless of whether viruses are aimed at stealing funds or are simply pests of the system, their removal is sometimes not an easy task.

Antivirus programs are not always able to save from a virus attack, even if a virus has been detected, not every security software can eliminate or deactivate it.

In addition, regular database updates are required, because virus developers are not asleep, applying new methods of bypassing protection and authentication, intercepting passwords, disabling the antivirus, etc. All systems, in fact, are vulnerable to one degree or another, and helps viruses to settle on the device is often the user himself.

Infection methods

Attackers go to different ways to force the user to download virus software on their own, attracting "free cheese" or stirring up interest in other ways, so the most common infection as a result of the actions of the owner of the device. Common causes of infection are:

  • Lack of installed anti-virus software, old update databases;
  • "Surfing" on sites. Exploring the depths of the Internet for different purposes, it is quite possible to catch the "infection", while it is not at all necessary to visit resources with "18+" content, there are enough viruses on portals with completely harmless topics;
  • Downloading software from questionable sites;
  • Launching unknown programs from unofficial resources;
  • Data exchange via open channels (Bluetooth, public Wi-fi).

It is not at all necessary that virus programs carry the ".apk" extension and are registered in the download folder, where they are easy to find and neutralize. There are many modifications of viruses, the most insidious of them can hide under the guise of system processes and files, as well as useful applications, and it is difficult to find a well-disguised pest.

By the way, in most cases, the installed antivirus still warns the user of a possible danger, but not everyone will cope with the desire to download something, if he has already conceived and leaves the page.

In addition, security software often mistake hacked applications for malware, so many ignore the defender's swearing by downloading files anyway.

Well, who doesn't want to get free cracked programs with features that are available only in paid versions of the software? Many users sin by downloading unofficial applications and interesting "goodies", risking to bring trouble to the device's system, which cybercriminals successfully use.

Often it becomes immediately clear to the user when the system has caught a virus, but in some cases the pest does not manifest itself at first.

In addition, users are often not very attentive to what is happening in the device's system, and until traces of sabotage are found, enough time will pass for the virus program to accomplish its goal.

Let's figure out how to determine if there is a threat from parasites and what to do if a tablet or smartphone on Android is still caught by a virus.

Symptoms of a virus infection of an Android device

Virus programs manifest themselves in different ways, depending on their purpose, and if you see one or more signs of their activity on your tablet or smartphone, you need to urgently take steps to get rid of the "infection". The following phenomena can indicate the presence of a malicious program on an Android device:

  • Deteriorated system performance. The device slows down, starts slowly, the response time to commands, including when launching applications, has increased significantly, lack of response to some actions;
  • Slowness of the browser, low download speed;
  • Spontaneous deletion of files from the device memory or their movement, editing. If it is noticed that photos, videos or other elements disappear, they are not found where they were before, that is, actions are performed without the participation of the user, then the device has acquired excessive independence precisely due to viruses;
  • The appearance of unknown applications;
  • Spontaneous making calls, sending messages;
  • Withdrawing money from a mobile account for no apparent reason;
  • Loss of funds from a bank account or wallets;
  • Appearance of requests for access to the camera, memory or Internet connection, administrator rights, etc.;
  • Blocking the launch of the OS of the tablet or other Android device, regular crashes, shutdowns and other system "glitches";
  • Blocking access to user data, individual elements or system settings;
  • The emergence of pop-ups, banners with advertisements;
  • Increased battery consumption.

If there is even the slightest suspicion of the presence of virus programs, or even the device "lives its own life", you must immediately check it for viruses. Next, let's see how this can be done.

Checking the device for viruses

Android versions higher than the fourth have a built-in scanner, which in some cases can detect virus threats, so if a standard tool is available, it doesn't hurt to launch it first. Other test options are more effective and, if the case is difficult, you can try each of them.

Using third-party antivirus software

There are many paid and free applications in the Play Market, with which you can check your Android device for viruses, and also get rid of them. To do this, you need to install the program, restart the device and start scanning the system.

In addition to downloading software from the official store, you can also do this by launching the installation manually using a file manager or transferring the antivirus from a stationary computer. Dr.

Web and ESET Mobile Security & Antivirus.

How to check Android for viruses through a computer

A convenient and effective way to identify threats is to scan the tablet for viruses through a computer. Since the antivirus is also capable of working with devices and storage devices connected to a PC, it also scans Android directly from the computer without installing it directly on the device. To do this, you need to take the following steps:

  • Connect the Android device to a stationary PC or laptop via a USB cable;
  • In the tablet settings, activate the item "Use as a multimedia device";
  • Find the connected device in the PC menu ("My Computer") and double-click to open the data;
  • Run antivirus on a PC, designate an additional device as a scan object;
  • After checking the tablet for viruses, the defender will give information with the results;
  • Next, you should try to disinfect or delete files.

The security software on the computer must have up-to-date anti-virus databases in order to effectively neutralize even new virus modifications.

How to find out if there are viruses in the system using online services

The easiest way to quickly find out if there is malware on Android is to scan your device using online services designed for this purpose. They allow you to scan your device in real time.

To do this, select the files and start the scanning procedure with the corresponding start button. After a while, the scanner will return results. Good online antiviruses include ESET Online Scanner, Kaspersky Online Scanner, VirSCAN.

Some services assume automatic removal or quarantine of the virus, while others only detect it, then you will have to remove it manually.

How to avoid problems and save the system

Antivirus services are not always able to cope with a pest that has settled on Androde. In cases where you cannot get rid of the problem after scanning the device, you can eliminate the threat yourself.

Eliminating viruses using root rights

Root-rights holders can use more advanced features by performing actions to delete any, even system files. Having administrator rights will help eliminate system parasites, but inept use, on the contrary, will lead to system failures.

In addition, the changes made may not allow the device to start at all, because it is not for nothing that the developers limit the user in these capabilities by default. With superuser rights, you can delete any items, as well as viruses, using the file manager. Many malicious programs in the “.

apk ”are located in the system / app folder.

How to clean your tablet from viruses in Safe Mode

If you cannot get rid of the virus program in the usual way, you can try to do it in safe mode, since in this case only the basic functions of the system will be launched without third-party applications.

Usually, the safe mode is turned on with the power button, which is held until the corresponding inscription appears, suggesting the transition of the device to this state, after which it is necessary to confirm the action.

In safe mode, you need to scan the system with an antivirus or delete infected files with your own hands, if you have root rights and already know the location of the source of the problem. To return to normal state, the device must be rebooted.

How to remove a virus from a tablet using a PC

It is possible to remove a virus from Android through a computer using a PC antivirus program or using a file manager for devices based on Android. If after the diagnostics by the defender, it was not possible to cure or eliminate the virus software, you can use Android Commander.

By running it on a computer, you can access the device information and perform various operations with them (moving, copying, deleting, etc.), for the most extended access, you will need to obtain root rights and activate USB debugging ("Options" - "System" - "Developer options").

Next, you need to do the following:

  • Connect the device to a PC like a USB drive;
  • With root rights, open the Android Commander manager, in the right part of the window of which the system elements of the connected device will also be displayed;
  • Find the executable file of the virus and eliminate it. This can be helped by copying to a PC and scanning each folder separately with an antivirus.

Extreme measures

If the tried methods do not work, there are guaranteed, but extreme ways to get rid of virus software on a tablet or other Android device:

  • Return to factory settings. You can get to the option using the system menu, if access to the system is not blocked by a virus, it is located in the personal settings in the backup section;

How to check an Android phone for viruses through a computer (PC) or laptop - tips

Checking Android for viruses through a computer

Let's see how you can check and remove viruses on Android through a computer and an antivirus program on it. Such a thing is needed if you are not sure that your antivirus on your phone is working correctly or the virus itself does not allow you to install an antivirus on it.

This article is suitable for all brands that produce phones on Android 9/8/7/6: Samsung, HTC, Lenovo, LG, Sony, ZTE, Huawei, Meizu, Fly, Alcatel, Xiaomi, Nokia and others. We are not responsible for your actions.

Search and remove Trojans

The most common type of virus on an Android device is spyware, popularly referred to as “Trojans”. They anonymously collect information about the owner of the tablet or smartphone (postal addresses, bank card data, passwords, etc.) and then send them to a specific server.

The main sign of the presence of a Trojan horse is considered to be a decrease in the gadget's performance (this is especially noticeable on weak devices) and an increased consumption of traffic on the Internet.

To remove a Trojan from an Android device, use the following steps:

  • Turn on USB debugging on the gadget. This feature is located in the "For Developers" section. In some models, this section is hidden. To make it visible, you need to go to the "About phone" menu and press the assembly number 5-6 times.
  • Enlarge

  • We connect the device to the computer using a USB cable. In the switching settings, select the "Media Transfer Protocol (MTP)" method. In older versions of the Android system, this mode may be called "Storage Mode".
  • Enlarge

  • If everything is done correctly, the new storage will be displayed on the PC in the "Devices and Disks" menu. Now you should run the anti-virus program on the computer.
  • Enlarge

  • For example, when using ESET Smart Security antivirus, open the PC scan menu in the program settings, then Removable media.
  • Click "All disks", thereby starting the check.
  • Enlarge

  • If malicious objects are detected, then we delete them.

Cleaning a mobile device from banners and viruses

This type of malware is installed on tablets and smartphones as separate applications and can lead to displaying advertising banners on the screen.

They prevent the owner from using the device normally and cause periodic freezes and severe braking.

Such a virus can get to an Android device from third-party sites, since all hosted programs on the Play Market are checked by the built-in Bouncer scanner.

When displaying advertising banners on the screen, it is necessary to examine the "Applications" section. If suspicious software is found there, then it should be removed completely.

If the malicious object is not deleted, but is displayed again after restarting the device, you can use the Android Commander program to solve the problem.

With its help, access to the external and internal storage of the gadget is opened and you can manually delete the infected program through the computer.

For the utility to work properly, you will need Superuser rights, which can be obtained using Kingo Root:

  • Install the utility on your PC.
  • We connect the gadget to the computer and activate USB debugging.
  • Now we launch Kingo Root. A window will appear where we click on Root to start the rooting procedure.

After opening the Superuser profile, proceed to treating the device:

  • We connect the gadget to the computer, and then scan its internal and external memory with the available antivirus.
  • If the check did not give a positive result, then install and run the Android Commander software.
  • We find the folder where the virus is located, and then delete it completely from the device. It is important to check the contents of the Data directory. This is where the residual files of the virus can be located.

When the virus is detected and removed through the PC, the gadget will regain its previous performance. To protect the device from such infection, in the settings in the "Security" section, you need to uncheck the box next to the "Unknown sources" item. Installing applications from third-party sites will be prohibited.

How to check Android for viruses

Checking Android for viruses through a computer

As the popularity of the Android operating system grows, so does the number of viruses for this OS. Typically, Android viruses distribute apps and display ads, but they can also steal your personal data or money from your accounts.

Therefore, do not ignore the possibility of infection. Now you will learn how to check Android for viruses using antivirus and through a computer.

Checking for viruses with antivirus for Android

The most reliable way to check an Android smartphone or tablet for viruses is to use antivirus software from the Play Market application store.

Now in the Play Market there is a huge number of various antiviruses, both paid and free.

However, most of these antiviruses are produced by well-known antivirus companies, some have earned their reputation by releasing antiviruses for Windows and other popular operating systems.

In order to check Android for viruses, you first need to select and install an antivirus. To do this, open the Play Market application store on your Android device and enter the query "antivirus" in the search box. After that, you will see a list of antiviruses that are available in the Play Market.

Study the available antiviruses, select the appropriate one and install it on your Android smartphone. When choosing, take into account the popularity of the antivirus company, the price of the antivirus, as well as the capabilities that it possesses. In this article, as an example, we will choose the free Mobile Security & Antivirus from the antivirus company AVAST Software.

After installing the antivirus, launch it and go to the "Antivirus scanner" section.

Then just click on the "Scan" button in order to start scanning Android for viruses.

Now it remains to wait for the end of the check. If viruses or other suspicious objects are detected during the scan, the antivirus will prompt you to remove them.

If the scan did not detect any viruses, then you can install another antivirus and repeat the scan.

Antiviruses for Android usually do not conflict with each other, so before installing another antivirus, you may not even uninstall the previous one.

How to protect Android from virus infection

In conclusion, we suggest that you familiarize yourself with the tips that will help protect your Android device from viruses in the future.

  • Download apps only from the Play Market ... This is perhaps the most important rule. By downloading applications from third-party sites, you run a very high risk of downloading a virus, especially if these are hacked applications.
  • Pay attention to app reviews and downloads ... When installing applications from the Play Market, you also need to be careful. It is worth paying attention to the reviews and the number of downloads. If you install only popular applications, then the likelihood of stumbling upon a virus will be much less.
  • Do not get ROOT rights ... Obtaining ROOT rights creates additional opportunities for viruses to penetrate, so it is better to refuse this procedure.
  • Keep track of what is offered to you in letters and on websites ... You should not follow the incomprehensible links that came in the SMS message. Also, do not agree to install or update any programs while browsing the web.
  • Use an antivirus ... Choose the right antivirus and make sure that it regularly checks your Android device for viruses.

How to check Android for viruses - diagnose your smartphone

Checking Android for viruses through a computer

Today, Internet fraud, which includes the viral infection of a gadget, is not news to anyone. To a greater extent, such threats relate to devices running the open Android operating system. Therefore, the question of how to check Android for viruses is more than relevant.

What is a virus and how is it dangerous on a smartphone

It is customary to call a virus a special malicious program capable of causing damage to a device, or rather to its owner.

Attackers create virus programs so that, once they get into the device, they begin to execute certain commands aimed at collecting the necessary information, sending SMS messages, opening URLs, unauthorized downloads of dangerous programs, etc., in order to subsequently forward this information to special servers and then use them for fraudulent purposes.

For example, from an infected device, unnoticed by the owner, SMS messages can be sent to short numbers, as a result of which significant amounts of money will be debited from the smartphone, and bank cards from which money will begin to disappear become vulnerable.

Signs of an Android virus infection

  • The smartphone starts to turn on longer than usual or "slows down", or even completely unexpectedly reboots.
  • Money began to be debited from the phone account by itself.
  • In the history of phone calls or SMS, you will see calls or messages that you have not made.
  • On the desktop of the gadget or when you open the browser, ads will appear that are not associated with any website or application.
  • The device was blocked, and the display began to display a message about the violation you committed, the need to pay a fine or transfer a certain amount of money for unlocking.
  • By themselves, some functions are activated, programs are installed, applications do not start, there is no access to files, electronic wallets, and a mobile bank.
  • Your account in messengers or social networks has been hacked, error messages appear in any application, antivirus does not start or disappeared, the battery is quickly discharged, the task manager shows unknown processes.

I must say that these signs may not necessarily indicate the presence of a virus, but any of them is a reason to immediately check your gadget for infection.

Checking Android smartphones for viruses

I must say that there is a fairly decent number of varieties of viruses (malware). All of them often perform different tasks, act in different ways and are created by completely different people, so there is no one universal method of detecting, let alone removing, malware from a device.

However, there are several standard methods that you can use if you suspect a gadget infection.

How to check Android through a computer

So, if we noticed that our smartphone began to behave somehow inadequately, then we connect it via a USB cable to our computer. Depending on the Android system, it can be displayed either as two media (SD card and Phone), or as two removable disks.

To carry out the check, right-click on one medium (removable disk) and select "Check for viruses" (or "Scan") from the proposed list of actions, then we repeat the same actions with the second one:

In the screenshot you can see that Kaspersky antivirus is installed on my PC and it will immediately start scanning, but you can also use the standard antivirus or any other installed on your computer:

Checking with special software

I must say that checking an Android smartphone through a computer may not reveal a malicious program. After all, the cunning and ingenuity of cyber fraudsters is truly limitless.

For example, we have already talked about the Android Backdoor 213 origin Trojan , which can remove the original application located in the system directory, and instead install a modified version, in which the virus itself is located.

Here comes the virus Android Obad 10 Origin who was also a separate material is devoted (the gadget is infected through the fake Google Play), it is able to obtain extended administrator rights for the Android device, then exclude its data from the list of applications and use the infected device as a remote Shell or proxy server.

In another article on our blog, we told how to detect and remove android smsspy 154 virus Is the most widespread threat on Android. This malware, having infiltrated a device, intercepts sms messages (including sms from financial institutions, protected by an mTAN verification code) and forwards them to fraudsters.

Well, it is impossible not to say about Trojan-SMS.androidos.fakeInst.ep, which in the people got the name of Google Wallet (or Google Wallet), skillfully masking under the Google Play Market's payment system. This villain after the introduction is engaged in extortion of the user of the bank card details. We also wrote in detail how to remove google wallet from android .

Install (if not yet installed) antivirus. Well established Avast Free Mobile Security:

Or Kaspersky Internet Security:

However, you may have other preferences, the benefit of the programs of this segment to date abound And it makes no sense to list everything.

So, first, we clean the browser cache, then open the application, and select the proposed scan version - fast or complete. We are waiting for the completion of the process.

If the viruses were detected, then several options for subsequent steps will be offered the program, we will leave to choose the one that will be relevant in a particular case.

Or at least we will know the way where to search for a malfunction (in most cases performed .apk-files of mobile viruses need to be signed in the System / App directory).

To then delete it using a file manager, for example, an ES conductor.

Online checking applications (.apk files)

Unfortunately, although it is extremely rare, but there are no cases of infection of the Android device through the installation of applications from Google Play, which can be about third-party, little-known sources. You can protect your smartphone from such threats by checking the downloadable .apk file for a malicious software using a special online service AV-Comparatives. .

Make it is quite simple: using the program menu, load the file that we scan and click " Start Analisys " After some time, we will provide a report on the inspection, which is performed absolutely free. There are some restrictions - without registration, the user can upload a file of no more than seven MB.

I would like to say that any virus without the participation of the user itself will not fall into a mobile gadget. Therefore, be extremely attentive:

  • Try to use Blocks and Advertising Filters
  • Do not attend dubious sites
  • Do not cross the links received from unknown senders.
  • Under any conditions do not report the numbers of their bank cards to any requests.
  • Install on your smartphone that deserves confidence anti-virus service, follow its regular update.
  • When installing applications, carefully read the contents of the Program to work, refuse those that require permission to send SMS, personal data or a change in any parameters.

How to check Android for viruses through a computer

Android check via computer

Many antiviruses for computers have a built-in function for checking connected media. Considering that the computer sees the Android device as a separate plug-in device, then this check option is the only possible one.

It is worth considering the peculiarities of antiviruses for computers, the operation of Android and its file system, as well as some mobile viruses. For example, a mobile OS can block anti-virus access to many system files, which seriously affects the scan results.

6. Click " Run check ".

7. When the scan is completed, you will be able to see a list of files that the program considers potentially dangerous. From this list, they can be placed in " Quarantine ", And from there it is already completely removed.

Last update: 02/11/2021

The number of malicious applications and files for Android OS is growing every year. And scammers and hackers come up with more sophisticated ways to steal money and personal information from the phone. Therefore, it is important to prepare and know how to check an android for viruses.

Ways to check an android phone for viruses

There are four methods for diagnosing a mobile device for viruses:

  1. Mobile antivirus software.
  2. Using a computer.
  3. Online check.
  4. Google Play Protect.

Method 1: Mobile Antivirus

Checking with mobile antiviruses is the simplest method available to every owner of an Android phone or tablet and does not require a PC. For verification, Android applications are used that work on the same principle as on desktop versions of the OS. Mobile antiviruses allow you to detect and remove installed applications with malicious code, report existing vulnerabilities, unwanted actions or files.

Instructions for checking:

  1. Download and install the anti-virus application. To do this, follow the link https://androfon.ru/antivirus-android , where popular and demanded anti-virus utilities are collected. Or go to the Google Play app store and search for "antivirus".
  2. Launch antivirus software and scan for threats. To do this, you need to update the signatures - the database.
  3. If necessary, configure the utility for in-depth analysis. This will increase the scan duration, but increase the likelihood of detecting threats.
  4. Wait until the end of the scan, make a decision if viruses are detected: delete, disinfect, quarantine, etc.
virus check 01
virus check 02
virus check 03
virus check 04

Important!

For reliability, it is recommended to install and scan your android phone with several antiviruses.

Before installing a new utility, you must remove the previous program to avoid conflicts in the system.

Most antiviruses are distributed under a paid license, with developers often providing a 1-4 week trial version for free. Do not neglect a trial license, as this will allow you to take full advantage of the antivirus.

Before installing the antivirus, it is advisable to visit an independent organization AV-TEST specializing in testing security software.

When downloading an antivirus program through Google Play, it is worth comparing the name of the utility and the developer. Often, attackers download fake apps with a similar name.

Method 2: Using a computer

The method is similar to the previous one, only instead of a mobile antivirus, a desktop version designed for a PC is used to scan an android phone for viruses. This type of diagnostics allows you to identify hidden threats missed by the mobile version. Detect unwanted files, as well as check programs downloaded from outside the official app stores.

Instructions on how to check an android phone for viruses via a computer:

  1. It is required to connect the device to a computer with an anti-virus program installed. Otherwise, you need to download and install the utility. To do this, use only official resources.
  2. In the phone connection settings, specify MTP (Media Transfer Protocol). This is necessary to display the device's memory in the form of removable disks.
virus check 05

Often, the Android system prompts you to select the type of connection when pairing the device with a PC. If this does not happen, you need to activate the item manually. This is usually done in the "memory" section of the settings section, sometimes in the "for developers" section. To get into the last one, you need to click 7 times on the build number in the item "about the phone".

  1. After displaying the internal and / or external memory, it is necessary to scan one by one. To do this, highlight the disk, right-click and select the item associated with scanning from the context menu.
  2. Wait until the end of the operation and delete the found malicious files.

Method 3: Online check

Many users prefer to download programs from third-party or pirated app stores. This often results in a virus being installed disguised as a normal program. Therefore, before installing, it is rational to check the file with a cloud antivirus or an online scanner. The service will analyze the contents of the installation apk-file and compare the data with the known virus databases. Such services will come in handy for users with no access to a computer or in the absence of a desire to contact mobile antivirus software.

Instructions for online check:

  1. We find a service to check. Let's use the free service as an example. virustotal .
  2. Download the application you like. For example, we will use one of the antiviruses in our catalog - G Data Internet Security Light, available here. https://androfon.ru/antivirus-android/g-data-internet-security-light
  3. On the virustotal page, the "file" tab, indicate the location of the installation application. This action is available from both a PC and a mobile device.
  4. If the file exceeds 128 MB, you should provide a direct link to the application in the adjacent "URL" tab.
  5. We are waiting for the results of the analysis, making sure that the application is safe, and then installing it on a mobile device.

Method 4: Google Play Protect

Android OS has built-in protection against malware - Google Play Protect. This is a passive antivirus, the quality of which is poor, as confirmed by the results AV-Test ... At the same time, the system is regularly improved, and with it the benefits.

virus check 09

Google Play Protect runs in the background. If the Internet is available, installed applications are checked once a day. A similar check is performed when installing the program via Google Play. If malicious code is found, the installation will stop. In practice, this is rare or not at all.

To use Google Play Protect, you just need to add a Google account to your mobile device. Then go to the app store. Call the hidden panel on the left and select the "Play protection" item. A new window will display information about the current state of the device.

Let's see how you can check and remove viruses on Android through a computer and an antivirus program on it. Such a thing is needed if you are not sure that your antivirus on your phone is working correctly or the virus itself does not allow you to install an antivirus on it.

Search and remove Trojans

The most common type of virus on an Android device is spyware, popularly referred to as “Trojans”. They anonymously collect information about the owner of the tablet or smartphone (postal addresses, bank card data, passwords, etc.) and then send them to a specific server.

The main sign of the presence of a Trojan horse is considered to be a decrease in the gadget's performance (this is especially noticeable on weak devices) and an increased consumption of traffic on the Internet.

To remove a Trojan from an Android device, use the following steps:

  • Turn on USB debugging on the gadget. This feature is located in the "For Developers" section. In some models, this section is hidden. To make it visible, you need to go to the "About phone" menu and press the assembly number 5-6 times.

Cleaning a mobile device from banners and viruses

This type of malware is installed on tablets and smartphones as separate applications and can lead to displaying advertising banners on the screen. They prevent the owner from using the device normally and cause periodic freezes and severe braking. Such a virus can get to an Android device from third-party sites, since all hosted programs on the Play Market are checked by the built-in Bouncer scanner.

When displaying advertising banners on the screen, it is necessary to examine the "Applications" section. If suspicious software is found there, then it should be removed completely.

If the malicious object is not deleted, but is displayed again after restarting the device, you can use the Android Commander program to solve the problem. With its help, access to the external and internal storage of the gadget opens and you can manually remove the infected program through the computer. For the utility to work properly, you will need Superuser rights, which can be obtained using Kingo Root:

  • Install the utility on your PC.
  • We connect the gadget to the computer and activate USB debugging.
  • Now we launch Kingo Root. A window will appear where we click on Root to start the rooting procedure.

After opening the Superuser profile, proceed to treating the device:

  • We connect the gadget to the computer, and then scan its internal and external memory with the available antivirus.
  • If the check did not give a positive result, then install and run the Android Commander software.
  • We find the folder where the virus is located, and then delete it completely from the device. It is important to check the contents of the Data directory. This is where the residual files of the virus can be located.

General rules for protecting your tablet or smartphone from viruses

The following tips will help protect your Android device from viruses in the future:

  • Keep track of what information you are offered on sites and in letters.
  • Use an antivirus.
  • Do not get root rights.
  • When choosing an app, pay attention to the number of downloads and reviews.
  • Download applications only from the Play Store.

If your mobile device does not have an antivirus, then you should install it to regularly check your gadget for viruses.

Modern operating systems have fairly effective standard mechanisms to combat various virus threats. They provide strong protection for computers and mobile devices, but sometimes the built-in tools are not enough and additional measures are required. The Android system is one of the most popular software platforms today, and therefore enjoys increased attention among attackers who develop malicious programs. According to reports from virus-fighting company G DATA, about 8,500 malware designed specifically for Android are leaked every day. Such information involuntarily makes you think about ways to protect your gadget.

So how do you know if there is a virus on your Android phone? Only antiviruses can reliably establish its presence, but external signs should not be ignored either. Infection of a mobile gadget can be indicated by spontaneous installation of applications, the appearance of advertising banners, a rapid consumption of traffic, an increase in communication costs, constant redirection to advertising resources, etc. There are also viruses that do not manifest themselves outwardly. They are precisely the ones that pose the greatest danger, since they are usually designed to steal confidential information, for example, banking data. This is why checking your phone for viruses is just as relevant as checking Windows computers.

Using mobile antivirus

So how to check your Android phone for viruses? There are several ways to perform a scan, and we'll start with the easiest one - installing a mobile antivirus. There are several dozen anti-virus applications in the Play Market store, but it is best to give preference to well-known software products, such as Dr.Web Light, Avast Anti-Virus, Kaspersky Internet Security, etc. It is desirable that the antivirus be able to scan not only the applications themselves, but also other objects in the file system.

Installing Dr.Web Light on a Mobile Device

The algorithm and modes of checking Android for viruses in different applications are different. For example, the free version of Dr.Web supports three main scanning modes - full, applications only, and custom. In the program settings, you can enable checking of the connected memory card and archives. Popular mobile antiviruses also offer background protection that prevents malware from entering the device itself.

Dr.Web Light application interface

Install anti-virus applications only from trusted sources, remembering that malware likes to disguise itself as anti-virus tools.

Phone check through computer

It's clear with mobile antiviruses, now let's see how to check Android for viruses through a computer. In this case, the gadget is connected to a PC via a USB cable and is checked as a removable medium, for which you need to select the MTP connection mode in the smartphone and enable USB debugging.

Enabling MTP Mode and USB Debugging

Then you should open the interface of the anti-virus installed on the computer, set a custom scan or scan for external devices and mark the connected phone.

Unfortunately, in most cases, a simple USB cable connection, even with debugging, will not be enough. The fact is that smartphones and tablets connected to a computer are defined not as storage devices, but as media devices with limited access rights. That is, the antivirus will simply not be able to see the gadget and, moreover, will not be able to scan it.

The gadget is not available for scanning on the computer

If your phone does not support connection in removable storage mode, you can only scan it for viruses through a computer as a network drive. To do this, using Google Play, you need to install the WebDAV Server application on the device. After installing the program, connect the gadget to your computer via USB, open the application and press the red “Start” button to start the server. In doing so, WebDAV Server will generate a local IP address.

Starting the WebDAV Server

On the computer, in the Explorer navigation pane, right-click on the "Network" icon, select the "Map network drive" option in the context menu and enter the local IP address given to you by WebDAV Server in the window that opens. Don't forget to assign a letter to the new drive as well.

Entering the IP address

After connecting, the device will become available for scanning by the antivirus installed on the computer, and you can clean the phone from viruses both from the context menu and through the interface of the antivirus itself.

Online scanners to check Android apps

Special online services help to scan the phone in order to detect viruses, but they should be taken only as additional tools due to the limited functions available. For checking individual files, the same APK applications, the AVC UnDroid tool available at undroid.av-comparatives.org/index.php will do just fine. On the specified page, you will be asked to select an APK file and send it for review, but the file size should not exceed 7 MB. To be able to upload large files, you need to go through the registration procedure.

VirusDesk is an online service designed to scan any files, not just Android applications. The principle of operation is the same - we go to the site, click the object selection button, specify the necessary file in the file manager, send it to the scan and get a detailed report. This scanner is available on the link VirusDesk.Kaspersky.ru.

Summary

Above, we told about how to check the phone android for viruses. However, it is equally important to know about the methods of reducing the risk of infection of the mobile device. The first and most important rule is not to install applications and games from unverified sources. Even in Google Play, there are infected applications from time to time, what to talk about little-known thematic sites, whose administrators do not bother themselves checking the files of the files. The same applies to the "left" firmware. The lack of reference to the official website of the developer and the form of communication gives a reason to think about it. Finally, try not to rut gadgets. The presence of root rights is, of course, nice, but it also increases the vulnerability of your Android device.

The spread of malware on the Android operating system is explained by the openness of this platform and its high popularity among inexperienced users. Despite the built-in means of protection, allowing to automatically block the majority of external threats, some viruses still penetrate the phone.
