A few days ago, we already learned how to avoid getting a virus on your smartphone, but if a previously unknown creature still penetrated the expanses of the system's program code, you should definitely resort to our advice.

However, before starting, let's determine for ourselves the main reasons for the appearance of a virus, however, it is more correct to say a malicious application, because, in fact, you cannot harm a smartphone by clicking on a web link. A device can become infected only by installing an infected application, and it is not necessary that it includes only a virus, the application will perform its functions, while with it the program code will penetrate into your system, which will steal, destroy and fill with garbage everything in its path .

Your main goal is to destroy the malicious code. If you notice something unusual in the behavior of your smartphone, for example: an unreasonable increase in memory, both operational and permanent, strange running processes, posts you have not previously written on Facebook - any strange behavior should alert you. First of all, remember which nearest programs you have installed and are there any suspicious ones among them? If yes, delete without hesitation. However, this is the easiest way.
The best option would be to turn off your device immediately after suspicious activity. Next, go to Google Play through a computer and analyze all known antivirus programs, read reviews, ask for advice from professionals. Then turn on your device again and download the selected antivirus application, scan and determine the presence of a virus.

Protect your data

To protect yourself from losing bank card data, personal accounts, accounts, try to change passwords from VKontakte, Twitter, Facebook, and other sites that are important to you, this will help you not become a victim of criminals. Whatever you say, but their key goal is to make a profit.

Reset your settings

If the antivirus did not find any malware, but the phone continues to behave strangely, a complete reset will help you: all your data, including music and photos, on the advice of colleagues from androidcentral transfer to a computer or transfer to Google Drive, then use our factory reset.

Do you have Root?

Some of you are probably familiar with root access, firmware, custom recovery. For these users, everything is much simpler, because they can simply change the firmware, before doing a full reset through the recovery, including battery statistics and so on, just to be sure.
What methods of fighting viruses do you use?

Recently, the number of virus programs written for the Android OS has been growing rapidly. And it's very easy to get them on your mobile device. Smartphones and tablets often store sensitive information and resources for e-wallet transactions. Attackers are trying to get hold of this data to steal money using virus programs. Therefore, it is important to know the signs of a device infection, as well as how to remove a virus from an Android phone and protect it from re-infections.

Unfortunately, the Android OS is open to virus threats. Luckily, it's curable 🙂

Malicious programs can significantly affect the operation of a smartphone and even cause it to fail. The following are some of the signs of a gadget virus infection:

the phone starts up longer than usual, slows down a lot, or there is a sudden reboot;
without your knowledge, paid SMS messages are sent or outgoing calls appear;
if funds are debited from the phone account;
the appearance of annoying ads in the browser or on the desktop;
screen lock with the requirement to transfer money to an unknown account for unlocking;
if it is impossible to access electronic wallets or there are monetary transactions that you did not make;
an unknown person has gained access to your social media account that you use from a mobile device;
Applications do not start or some functions are blocked;
The phone's battery drains very quickly.

If one or more of these symptoms appear, we recommend that you scan your device for viruses.

If you find symptoms of a virus infection on your phone, do not despair. Follow the steps below

Ways to deal with viruses in the Android OS

There are many ways to successfully remove a virus from your phone.

To avoid the need to fight a virus, it is best to prevent it from getting into your gadget. A simple rule of thumb is to only install apps from official app stores like the Play Store or Play Market.

Cleaning your phone with antivirus

Also, various antiviruses for Android provide reliable protection. The most popular of them are Dr. Web, Avast, Kasperskiy and others. This software is recommended to be downloaded from the official website of the developer. Typically, antivirus programs operate in the background and, if a threat is detected, they report a problem.

Before you clean Android from viruses, you need to run a full scan of the device's built-in memory and memory card. If the antivirus detects a malicious program, you should select the “Delete” function. In this case, it is better to quarantine the neutralized copy of the application if the protection program erroneously identified it as a virus.

It should be noted that application scanning does not help detect and remove malicious software in all cases. Many virus programs are protected from deletion and are able to recover. In addition, the device may be partially or completely blocked and it is generally impossible to run antivirus programs. Therefore, the question arises of how to remove a virus from an Android phone if it is not removed by an antivirus.

How to clean your smartphone in safe mode

If it was not possible to remove dangerous software in normal mode, you can try to do it in safe mode. Since virus programs are usually not active in the safe mode of the device, you can try to destroy them.

To switch the gadget to safe mode for a version higher than Android 4.0, press the power button. Then, in the menu window, hold your finger on the line "Turn off the power" until a window appears with the message "Switching to safe mode." Press OK.

For versions of Android 4.0 and below, you need to turn off and turn on the device in the usual way. During startup, when the Android logo appears on the screen, you should simultaneously press the volume up and down buttons. You need to hold them until the system is fully loaded.

Now the device has switched to safe mode and you can scan it with an antivirus program. If your phone does not have one or it does not start, you should install it from the application store.

Thus, viruses that impose advertising or download various applications to the smartphone to increase the rating are effectively removed.

To return to normal mode, you just need to reboot the device.

How to remove a virus from an Android phone through a computer

Another way is by connecting it to a computer. It is used when the functions of the smartphone are partially or completely blocked.

Usually, a computer antivirus automatically requests a scan when connecting any device to a PC. But if this function is not available, then you need to manually select the phone's memory for scanning in the settings of the computer's anti-virus program.

To do this, you need:

When connecting the smartphone to the computer, select the option "As a USB storage device".
In the "Computer" folder on a stationary PC, logical drives will appear, indicating the internal memory of the gadget and an SD card, if any.
In the context menu of each of the disks, select the "Check for viruses" function. Scanning started.

Reset phone settings on Android

If none of the methods gave results, and the virus is not removed, then you should resort to at least - factory reset. Although this operation is the most efficient method, it deletes all user information from the internal memory.

Therefore, the necessary photos, music, videos and documents must be copied to other media before resetting. At the same time, be careful not to accidentally transfer the virus along with your data.

To restore factory settings through the system menu, you need to go to "Settings" and open the "Personal" folder. Next, click "Backup" and select the "Reset with factory settings" option. After rebooting the device, you will be prompted to select the language and other settings.

Prevention of virus infection of Android devices

It is better to prevent the threat of virus infection than to deal with malicious software. Therefore, to protect your mobile device, you should follow these simple tips:

You need to download and install applications from official sites and do not use hacked programs.
Install an antivirus program and activate it.
Do not put your gadget into developer mode. This may make it more vulnerable to viruses.

Android phones and tablets are gradually replacing Windows computers. The operating system becomes attractive to scammers who develop virus programs. Android's vulnerability to viruses allows attackers to gain access to users' SIM cards, passwords from accounts and electronic wallets, as well as bank accounts. Smartphones and tablets are protected by built-in Google blockers, as well as antiviruses. How to remove a virus from an Android phone and whether the device needs an antivirus - read our article.

Virus programs are conditionally divided into four groups:

emptying the user's balance;
stealing access to electronic wallets and bank cards;
storing personal data - logins, passwords, documents;
blocking device.

Every year, new blocking components appear in antiviruses, and unique protective mechanisms are developed to block malicious programs. However, viruses continue to attack smartphones and tablets. This happens, in many respects, through the fault of users who ignore pop-up system windows with danger warnings. The desire to install the game is stronger than the thought of a possible write-off of money or blocking the gadget.

Antivirus is necessary to protect android devices, provided that the user responds to warnings and follows the instructions of the program.

How viruses get into the system. How Function Blocking Happens

Viruses penetrate smartphones and tablets due to the inexperience of the user.

path of penetration	Solution
Advertising	In order not to download the virus, the user just needs to close the advertising page, but the message directly indicates the consequences of inaction: “the application will not work correctly without updating; you will not be able to watch movies; there is a possibility of infection with the virus” and others. The user gets scared and reluctantly clicks the "Update" button. A virus application is installed in the system.
Appendix Attackers play on the user's desire to get a game or application for free, so they create analogues of paid programs from the Market, adding malicious code to them.	Install applications only from the Play Store and official developer sites. Install applications only from the Play Store and official developer sites

Common manifestations of viral activity:

increased battery consumption;
increase in expenses for mobile communications, regular write-offs of small amounts from the balance;
the appearance of unfamiliar files and applications;
slow work of the gadget;
pop-ups and banners.

Most viruses do not manifest themselves, and the user understands that his gadget is infected only at the moment of debiting funds from a card or electronic wallet.

List of effective antiviruses

If you find that your smartphone is infected with a virus, first of all, remove the SIM card to avoid resetting the balance. Next, install an antivirus program and scan the system. Applications can be downloaded from the Play Store or from the official website of the developer. To install the .apk file from a computer:

Go to the website of the antivirus developer and download the installation file.
Connect your smartphone or tablet to your PC in mass storage mode.
Open a removable drive and copy the antivirus file to the selected folder.
Disconnect the device from the computer.
In the gadget menu, find the File Manager and use it to open the folder with the antivirus file.
Install the program.

What to do with a virus if the antivirus did not help

If the antivirus does not cope with the malicious application or does not detect it, the virus will have to be removed manually. There are four key ways to deal with viruses on Android:

disabling administrative rights and then deleting the application containing the virus;
checking a smartphone or tablet with an antivirus on a PC;
reset settings to default;
flashing a smartphone or tablet.

The way to eliminate the virus depends on its type.

Trojan

Trojans infiltrate the system and collect the personal data of the owner of the gadget, as well as send requests to paid numbers. If you have root rights and know which application is causing harm, open the file manager and go to the application directory along the path data/app. By deleting a dangerous program from a folder, you don't have to worry about virus activity.

If you do not have root access, restart your smartphone or tablet in recovery mode. To do this, turn off the device, and when you turn it on, hold down the power and volume down / volume up buttons at the same time. From safe mode, disable admin rights for the Trojan app and uninstall it.

Virus that installs applications on the phone

The most dangerous is a virus that can install applications on its own and create its own files in directories. Having obtained administrator rights, an application infected with a virus installs intrusive banners and programs, penetrating deep into the system. As a result, the gadget freezes and stops working normally. To eliminate a virus:

Check the device with antivirus software. Remove all suspicious applications.
Open the application manager through "Settings - General - Applications - All" and manually remove unknown programs, after clearing the cache and stopping their work.
Get root access to the device using the Kingo Android Root or Farmaroot application.
Disable internet access, download Root App Deleter and remove remaining virus program files.
With the Internet turned off, manually delete the residual files left by viruses from the system / app folder. Use ES File Explorer.

If a smartphone or tablet is infected with the Android.Becu.1.origin virus, the method described above does not help. Try to block the activity of a malicious application:

In the list of installed programs, find the infected package file com.cube.activity, open it and select "Disable".
Uninstall the auxiliary packages left behind by the virus: com.zgs.ga.pack and com.system.outapi.

The virus will be stopped.

Com android systemUI

Running com.android.systemUI provokes a Trojan installed on a smartphone along with an unlicensed application or game. The virus downloads adware apps, porn site banners, second-rate cleaners and battery boosters to the Android system. You can remove the virus only if you have root rights:

In the Application Manager, find the program containing the virus, open and select "Stop". Then click "Clear Cache" and "Delete".
Open the file manager (ES Explorer or X-Plore), go to the "Root - System - App" folder and find the com.android.systemUI file inside.
If this is not the case, the virus developers have come up with a different name for the file. Calculate the file by the installation date - it must match the installation date of the infected application.
Delete the virus file. Use the Delete 2 application if necessary.

The action of the virus will stop after the gadget is rebooted.

Ransomware viruses - Interior Ministry banners, battery damage

A ransomware virus that prevents the use of a smartphone or tablet by displaying a banner in full screen that looks like: “Your device has been blocked by the security service of the Ministry of Internal Affairs of the Russian Federation.

To activate access to the device, transfer 300 rubles according to the details. There are three ways to remove the banner and the virus that caused it to appear:

factory reset via Android recovery mode;
uninstalling the application through safe mode;
gadget flashing.

In Android safe mode, only system applications are launched - accordingly, the virus will be inactive. To start safe mode and uninstall an infected program:

Turn off your smartphone or tablet.
While turning it on, hold down the lock and volume buttons at the same time.
Open Settings - General - Applications - All.
Select and stop the malware.
Clear the cache and uninstall the app.

Flashing and resetting to factory settings should only be used as a last resort - these methods lead to data loss. To reset settings:

Connect the gadget to the PC.
Activate recovery mode.
Select wipe data/factory reset and click
On a computer, copy important data from a removable drive and format it.

After the reboot, the smartphone will return to factory settings, and the virus will be removed.

Security/Firewall service

The virus interferes with the work in the browser and applications. When the program starts, a black screen appears with the inscription Firewall Service. If you just close the window, it starts up again.

Antiviruses and traditional methods do not work in the fight against the Trojan. To remove the virus, uninstall the application with which it was installed, then get root access and use the file manager to delete the Firewall Service (gmk.apk) and SecurityService (gma.apk) files from the system / app folder. After the reboot, the virus will stop working. If this does not happen, repeat the steps, but to delete the .apk files, use the "Delete 2" program instead of the usual manager.

Engriks

Engriks is a virus that launches intrusive banners and installs "left" applications on a smartphone or tablet. After detection and removal by the antivirus, it occurs again.

A hard reset, that is, a system rollback to factory settings, helps to cope with the malware. To perform a hard reset:

Turn off the device and when you turn it on, go into recovery mode.
Select wipe data/factory reset from the menu.
Wait for the final reset.

Browser ad virus - how to block

Certain viruses only infect mobile browsers. Having opened the Internet browser, the user sees advertising banners instead of pages, often with obscene content. It is impossible to close ads, they appear again. Most often, the virus hides in the browser cache, and to combat it, it is enough to clear the cache:

Go to the menu "Settings - General - Applications - All" and select the browser in which banners interfere with you. Open it.
Click the Clear Cache button and then Stop.

If the banners reappear when you restart the browser, uninstall the viewer itself and reinstall it after scanning your smartphone or tablet with an antivirus.

SMS Manager: how to block a threat yourself

SMS viruses send requests on behalf of the user to paid short numbers, for which amounts from 30 to 300 rubles are debited from the balance. The user does not notice the write-offs immediately - today there are few people who track the balance of funds on the number. To remove a virus:

Go to Application Manager.
Find apps recently installed that request access to SMS messages.
Delete them by first clearing the cache and deleting the data in the same place, in the Dispatcher.
Install an antivirus and scan the system.

Remove detected malware. The antivirus may show a warning that if you uninstall the application, you will lose all your data. These are the intrigues of the virus developers - they deliberately replace the text of the system message so that the user gets scared and refuses to remove the malware.

How to remove a virus file using a system computer or laptop

If after all the actions the virus continues to cause harm, check your smartphone or tablet with an antivirus through a PC. For this:

Connect your device to your computer in mass storage mode.
Open the antivirus on your PC (use Dr. Web or Kaspersky) and run a custom scan.
Mark for verification the removable drives that appeared when the gadget was connected.
Delete the found files.

After checking, turn off your smartphone and restart it to permanently eliminate virus activity.

Prevention of viruses on smartphones and tablets

After removing the virus, take care of the security of your smartphone or tablet in the future. Install an antivirus program and set a weekly timed scan. When working with the device, follow the rules:

install applications only from the Play Store and official developer sites;
do not save on paid programs;
in the device settings, uncheck the box "Allow installation from unknown sources";
try not to download applications that request access to SMS and calls;
if you see a message on any site about the need to update one of your applications, ignore it - update only through the Play Store;

Do not perform important operations while working on Wi-fi - traffic can be intercepted by intruders.

By using an antivirus program and judiciously installing applications, you will protect yourself and your device from the negative effects of viruses and malware. If the virus has penetrated the android, do not follow the scammers, but consistently try to eliminate it by various methods.

Our gadgets are protected from malware by a special program from Google. But it has small loopholes and infections of Android phones are rare, but they do happen.

Hello, dear readers of the blog "Mobile Home"!

The emergence of a large number of programs that can be downloaded for free and the widespread use of the Internet have untied the hands of all kinds of hackers and "pests" who have begun to create viruses that can infect a mobile phone or smartphone. An embedded virus can perform various operations on your device, including debiting a bank account linked, for example, to your Google account.

It's pretty easy to get a virus on your phone. Any file you download from the Internet has the potential to contain a malicious script. Active email users who open an email sent by the system to spam are also often attacked.

More precisely - what do those who create and launch viruses into the network need?

Most of the time they need money. Therefore, attackers try to get information about your bank card in any way in order to then transfer funds from your account to their own. The virus that got into the phone does not show itself - it is remotely controlled by the owners, and only at their command will it begin to act.

A large team of professional programmers is working on ways to treat smartphones from viruses and fight them. But hackers don't sleep either. They improve their Trojans and write more complex codes each time. Modern viruses are able to collect complete information about the owner of a smartphone: all personal data, photos and videos, phone numbers, passwords in social networks. They can also block incoming phone calls.

After reading the lines above, you may experience a panic. But do not worry ahead of time. There are ways to protect yourself from the unpleasant consequences of a malware infection.

How to check your phone for viruses?

There are special programs - antiviruses that scan the operating system and, if suspicious scripts are found, inform you about it.

How to prevent virus infection? Experts give some practical advice, following which you can protect your device from harmful programs:

In no case do not turn on "Developer Mode" .
Do not install programs from third-party sources - they should be downloaded only from official sites.
Follow the information that the program requests during installation.
Install an ANTI-VIRUS program!

The last point is key. If you want to protect yourself as much as possible, then do not spare the money to purchase a paid professional version of the antivirus program.

What to do if the smartphone is infected?

If you know the source of the problem, you can try to remove the program that is the carrier of the virus (read about). If the malware is detected by the antivirus, it will prompt you to remove it.

There is another way to treat - reset to factory settings. In this case, all information will be deleted from the phone. After the reset, you must immediately install antivirus software and run diagnostics.

The virus may remain on the removable memory card. It is better to scan it separately on a stationary computer using a proven antivirus. As you already understood, installing professional anti-virus programs with constant updates is the best means of prevention. Don't neglect it!

Sincerely, Sergey Chesnokov
