If an Android smartphone or tablet starts acting weird, there is a small chance that the device has a virus. Today we will tell you how to remove a virus on Android and get rid of malware in the future.

Different ways to remove viruses on your phone and tablet and what they are

Viruses on Android are not so common, but they do exist. As a rule, they enter the system through programs of dubious origin, so it is better to download applications from official stores, such as Google Play.

Those whose gadget crashes due to the actions of malicious applications will find in the article a useful description of how to enter safe mode and, if necessary, restrict the rights of the program, and then remove the virus.

If this option does not work, you can try a factory reset, although without a previously created backup of the system, it is better not to do this.

Before moving on to the main part of the article, I would like to focus on the fact that there are no viruses on Android smartphones or tablets in the usual sense of the word.

Most often, the actions of a virus consist in showing ads that say that the device is infected, and to remove the virus, you need to download some application or in the slow operation of the device.

Android without viruses - how is it possible?

  1. Do not install apps: Do not install apps from unknown sources unless you are sure they are trustworthy. In general, the third-party app installation blocking feature is usually disabled by default. Enabled in the settings of the smartphone or tablet. Open "Settings", then go to the "Security" section and uncheck the box next to the line "Unknown sources".
  2. Refrain from installing clone applications: even if you only download apps from Google Play, apps with malicious code can still be found there. Therefore, you should not download clone applications from unknown developers, as well as applications that simply do not perform their functions.
  3. Check application permissions: no matter where the application is downloaded from, before installing it, you need to check which functions and services it requests access to. In no case should you give the program administrator rights, since in this case there will be some difficulties with the removal. You should be alerted if the video player for some reason requests access to contacts. You can also search the web for reviews of the app or go to the developer's website to get a better idea of ​​the app.
  4. Update system: it may be that the most recent version of the Android operating system will not be available for your device, however, it will not be out of place to check that it is as recent as possible. Accordingly, it is worth giving preference to the manufacturer that regularly releases updates for the software of their device (for example, Nokia).
  5. Install antivirus: on Android, you can do without an antivirus, but for those who are worried about how not to pick up a virus, it will be clearly calmer with it. Also, antivirus applications, as a rule, in addition to the main one, have several additional useful functions. Keep in mind that Android antivirus may have false positives, which you can ignore if you are sure that the application is clean.

How to get rid of a virus on Android

We enter safe mode on a smartphone or tablet. In this mode, applications from third-party developers will not be able to start, including those with malicious code.

On many devices, to bring up the shutdown menu, you need to press and hold the power button, then select "Power off" and the device will turn on in safe mode after rebooting.

If you can’t enter safe mode according to our description, open Google and enter “How to enter safe mode on [write your device model here]” and follow the instructions found.

Booting into safe mode, we see the inscription "Safe Mode" in the lower left part of the screen.

Application settings

Open "Settings", go to "Applications" and go to the "Downloaded" or "Third Party" tab.

We come here because it is highly likely that the user will find out about the application, after installing which the gadget began to fail, comparing the time of occurrence of failures and the time of installing a new application.

If you don’t know which application is interfering with the normal operation of your smartphone or tablet, you should go through the list of all applications and find some suspicious one or one that you didn’t install at all.

We click on the malicious application and we get to the screen with information about it, click "Delete".

In most cases, this action is sufficient to remove the virus, but it may also be that the "Remove" button is not available.

This happens because the application has administrator rights.

Then we exit the "Applications" section, return to "Settings", go to "Security" and look for the line "Device Administrators". All applications with administrative rights are stored here in the form of a list.

  • Just uncheck the app you want to uninstall.
  • We return to "Applications" and see that we can now delete the application.
  • The virus has been removed, it remains only to reboot the device to switch to normal mode.

The problem has been fixed, but it would not be superfluous to back up important data on your device and install an antivirus for preventive protection.

Each type of malware has its own characteristics, so the options for eliminating them differ from each other. In this article, we will look at examples of the most common malware and methods for effectively neutralizing them.

This type of virus is the most popular. You can find a Trojan on almost every device. Dangerous software reliably hides ongoing actions, being encrypted under the guise of another program, and sends paid hidden SMS. In addition, he is able to read the information of bank cards and codes that are recorded in messages, contacts. You can eliminate it like this:

How to remove ad-type virus from phone?

This malware is also quite common, but it differs from the previous one in that it is aimed more at making money through ads, and not at extracting money or harming the device.

You can solve the problem in several ways manually for free:

  • Activate airplane mode. This will disable the network and other types of pairing so that advertising cannot be loaded or displayed. These actions are suitable for applications and game content that function without an Internet connection. To activate the mode, hold down the power key and select the desired action in the window that opens;

  • turn it on, further actions should be performed as soon as possible, before the banner is activated;
  • go to settings (developer options);

  • enable debugging via USB;

The above actions will help block the pest, and the infected program can be removed in the usual way. After the destruction of the virus, it is necessary to reset the settings to the factory settings in order to ensure stable and correct operation of the device.

We remove mobile viruses through a computer

A computer can help in cases where anti-virus products on a mobile phone are unable to cope with their functions even in safe mode or the device's functionality is limited, blocked. There are a couple of ways to remove dangerous software:

  • through a computer antivirus;
  • using a file manager for mobile devices on Android, for example, Android Commander.

Antivirus on PC

Connect your tablet or smartphone to your computer equipment using a USB cable. You need to select "As a USB drive". After that, a couple of additional "disks" will be available in the "Computer" folder - a memory card and the internal memory of the device. Scanning can be started by opening the menu of each disk, for this there is an option "Check for viruses".


Let's use Android Commander

This is a specialized utility for file exchange between a gadget and a computer. Activating on a PC, it gives the user access to the phone's memory, helps to copy, move and delete various data. To get full access to the contents of the device, you will have to take care of root rights in advance and connect via USB. This was mentioned above, but we note again that such debugging can be started like this:

Settings/System/Developer options

Next, the gadget connects to the PC and starts with admin rights. In it you can see all the protected directories and objects of the Android operating system. On the right side of the Android Commander window are the directories of the smartphone. In them you need to find the application file with the .apk extension, it is he who causes problems, eliminate it. You can simply copy the dubious folders to your computer and scan each separately with an antivirus.


What to do if the threat is not removed?

If all the actions described above did not help, you will have to move on to drastic measures:

  • firstly, reset and restore factory settings through the system menu;
  • secondly, hard reset in the Recovery menu;
  • Finally, reflash the hardware.

Each of these methods returns the device to a new state, that is, it will not have any user data, settings, files. The Google account will also be deleted. So take care of backup versions in advance, it is better to do them manually so as not to copy the virus. Then you can start "treatment".

How to remove a virus from an infected phone? To do this is actually not very difficult, you can use one of the proposed options. It is only necessary to determine the type of threat in order to use the right "weapon" for it. Another tip - be sure to install antiviruses on your Android to avoid dangerous infections.
