Modern Cell Phones and smartphones – quite full-fledged computers with their own operating systems, and virus infection is also not alien to them. Do you remember the story of the spring of 2015, when millions of rubles were written off from Sberbank accounts of almost 25,000 depositors? And according to the latest police data, hackers wrote off about 8.5 billion rubles from the accounts of owners of mobile gadgets in 2016 alone.

Ways of infection with the virus

To begin with, it is useful to learn more about the sources of viral infection and the symptoms of the disease. The theft of money occurred by introducing a virus through downloading supposedly useful free applications using links from SMM messages. The user installed the application, and it turned out to be a spyware virus that monitored logins and passwords for logging into the bank. Well, then it’s a matter of technique, how exactly to transfer money to the attackers’ account.

Another common source mobile viruses are emails with links and an invitation to visit a site. But the site turned out to be phishing, the user entered personal data and again lost something.

The third known way of virus infection is downloading and installing applications from third-party sources. Modern models mobile operating systems have a default ban on installing programs not from Google Play or App Store. Upon attempt third party installation The security system necessarily warns the user about existing risks. However, it is possible to manually disable the ban and as a result, the user often gets problems with the phone instead of enjoying the offer.

Signs of a virus infection on your phone

• Some applications stop working.
• The system begins to slow down and glitch.
• Documents and files disappear.
• Installed antivirus programs signal the presence of threats.
• The phone stops working completely.
• Your accounts on social networks or financial institutions indicate outside interference - something has been changed, money disappears, and so on.

Some of these manifestations may not be related to viral infection, but indicate that the system has not been cleaned for a long time and how dirty it is, that the power mobile computer There’s simply not enough to pump up all this unnecessary abundance.

How to remove a virus from your phone

The most serious problem is that when the mobile system is actually infected with viruses, the phone begins to work so slowly that it is almost impossible to resort to classic recommendations, such as:

1. Download a professional antivirus, scan and remove viruses.
2. Launch antivirus scanning available security programs.

Unfortunately, none of this can be done; the display does not respond to touch, and the buttons do not work either. If any reaction follows, it will only be after a very long time.

Reset to factory settings

If the phone memory does not contain any particularly important or valuable information, it is recommended to use a drastic remedy - reset the phone to factory settings.

This procedure is equivalent full formatting system, followed by a fresh installation of everything again - both the operating system and all applications.

It is not surprising that such a dangerous option is hidden in one of the farthest corners of the menu.

Some devices have a special button or hole to press to reset the system - you need to find out this in the instructions. All this time the phone must be connected to charger to avoid failure. Remove the memory card in advance and scan it with an antivirus on a desktop computer. For reliability, format the memory card.

Treatment with internal remedies

If your phone is infected but still works, you can download trial version some paid high-quality antivirus and scan. All popular antiviruses– Dr.Web, Kaspersky, Avast, ESET have versions for Android and iOS. Well, in management mobile antiviruses much simpler than telescopes.

We chose free version Dr. Web for Android phones.

After loading, a completely ordinary and clear menu appeared, which was easy to use.

The scanner was immediately launched, but it did not find anything, because the phone is practically never on the network, since this is not required. For comprehensive protection you can download another product from Dr. Web.

As the screenshot shows, not all of its options are free, although you can try it right now. Both applications are available on Google Play.

Treatment of phone viruses using a computer

If the phone does not respond to commands, you can try connecting it to desktop computer and scan existing on your desktop powerful antivirus. The only problem is that standard applications may not respond to executable Android files. This is a completely different architecture, and the protection may not recognize malicious file as a threat.

In this case, the computer does not treat the phone as another computer, but simply as external storage. Accordingly, anti-virus scanning will be carried out precisely at the level of the phone’s local memory. So viruses, deeply rooted mobile system, in this way it is unlikely to be found and neutralized.

After treating your phone for viruses, be sure to install two or three good virus scanners and never install applications from unknown sources.

Protects our gadgets from malware special program from Google. But it has small loopholes and infections of phones with the Android operating system are rare, but they do happen. Viruses almost always enter the system along with low-quality applications. There are several types of malware. Each of them will have to be dealt with differently. In this article you will find the most simple ways remove viruses from your phone.

How to remove adware from Android

This type of malware is the most harmless. His task is to sell a product, not to damage the system. There are several ways to solve this problem.

• More often ad virus gets into the phone along with the games. If you don't want to delete interesting application, just block annoying ads. To do this, turn on airplane mode on your phone. Access to the Internet will be blocked, and without access to the network, advertising will not appear.

• Scan your phone with antivirus. The most popular is Dr. Web. You can download it at Google play. It will easily detect and neutralize any advertising virus.

How to remove Trajan virus from Android

There are many types of “Trajan”. Some send SMS to paid numbers, others steal passwords or bank card numbers. Most often, the virus disguises itself as another, completely harmless application. To remove it, follow the following algorithm:

• download a high-quality one to your device antivirus program, for example, Lookout;
• scan your phone;
• remove all suspicious applications that the antivirus detects.

How to remove a virus banner from Android

This type of malware completely blocks the phone from working. To remove the banner, the virus demands a large sum money. But it won't be difficult to get rid of it:

• get a SIM card as soon as possible before money is withdrawn from your balance;
• charge the switched off phone to 100%;
• turn on the device;
• as quickly as possible, before the virus banner appears, go to the settings;
• find “For Developers”;
• enable “USB Debugging”;
• select the debug field containing the malicious banner;
• remove the infected application;
• return your phone settings to factory settings.

Thus, it is easy to eliminate the virus from any device on Android based. To prevent future malware, install only popular apps and periodically check your gadget with an antivirus.

Alas, Android systems, as well as stationary Windows versions, are susceptible to viruses and malicious codes. Every new virus The "Android system" itself cannot recognize, although in the most latest versions The system has a pre-installed scanner. That’s why you have to use various kinds of third-party software (at least to get rid of the threat that way). However, there is no need to panic even if the mobile device can store confidential information, used for example banking applications. But in most cases virus attacks are aimed specifically at them. We will talk further about how to remove a virus from Android on a phone or tablet.

For such cases, several solutions can be proposed, which, however, differ quite greatly from each other. We will separately consider issues related to situations where it is impossible to remove a virus using the proposed methods. Unfortunately, such situations also occur, and many protective tools are powerless to bypass blocking access to virus files (programs like Unlocker are not provided for mobile devices). But first things first.

How to check Android for viruses: problems and difficulties

The most a big problem half of the known versions of Android is that initially they did not provide any serious security measures. At least antivirus packages had to be installed from the repository Play Market(Android games without viruses or other programs can also be downloaded there, but Lately and they were attacked, and the user uploaded to mobile device already pre-infected application).

In versions above four, a virus detection tool appeared, but it has nothing to do with how the same stationary scanners work at the entrance. Thus, the most primitive solution to the question of how to check Android for viruses may be its use. Of course, you shouldn’t rely on 100% success, since such scanning, according to statistics, detects threats only in 30-40% of cases, nothing more.

In such a situation it is better to use third party applications, downloaded from the same storage, however, due to the impact of the virus on the system, they may not be installed. Next, let's look at how to remove a virus from Android for different situations. It is assumed that at least one solution will work (drastic measures will definitely have an effect, but more on that later). And most of these methods are not as complicated as it might seem at first glance.

How to remove a virus from Android on your phone: main directions of action

If we outline the processes for removing threats that have penetrated a mobile device in in a general sense, there are several basic options for action that will help eliminate threats. Among them, the priority ones are:

• using special software directly on the gadget;
• scanning and removing viruses when connected to a computer;
• full reset to factory settings.

Regarding the last point, we can separately say that the problem of how to remove a virus from Android, restoring from backup copy can't be solved. Firstly, the backup itself may initially contain a virus, and secondly, the threat may settle on a removable card, and recovery will be carried out exclusively for the main (internal) drive.

We use built-in protection for versions 4.0 and higher

So, first of all, all owners of operating systems higher than the fourth version are recommended to check their gadget with the built-in antivirus immediately after the first symptoms of infection appear. Signs of a threat penetration may include slowdown of the device, spontaneous reboot, the appearance of calls that the user did not make, or sent messages of the same type, installation of applications in background without the owner's knowledge, loss of access to electronic wallets or bank cards, startup failure installed applets with errors about failures in com.android.systemUI, fast discharge battery, etc.

In this case, you just need to run the scanner and see what it finds. There is little hope for it, but in some cases you can get rid of the most primitive threats in this way.

What to do with an OS below the fourth modification?

For modifications below the fourth, the problem of how to remove a virus from Android can initially be solved by installing third-party software. You can find a lot of programs, but it is better to use utilities from well-known developers.

The first step is to install Kaspersky antivirus on Android and completely check the system. Of course, the load on resources if you constantly keep the application active will increase quite significantly (similar to Windows), but you can simply scan and remove viruses, and then uninstall the main program itself.

If the application is not installed from the Play Market, access to which or its operation may be blocked due to the impact of the threat, you need to find another trusted source on the Internet (official website), download mobile version applications from there, transfer it to removable card memory and install via APK file.

Using advanced antivirus software

But you don’t have to limit yourself to just narrowly focused utilities. For example, many optimization programs designed to clean the system of debris and speed up its operation also have built-in anti-virus modules.

If antivirus software does not work or does not find any threats, you should scan more applications general actions. Perhaps their virus is like software, counteracting its functioning, and does not recognize it.

Safe mode

Finally, the question of how to remove a virus from Android if the software is not installed or the threat itself is not removed can be resolved by switching the device to secure boot. It's sad, but not all users know how to do this.

To do this, you need to hold down the on/off button and hold the confirmation button on the screen until a message appears prompting you to switch to safe mode (for versions above the fourth). For OS modifications 4.0 and below, you need to turn off the device in the usual way, turn it on again, when the system logo with a green robot appears, simultaneously hold down the volume up and down keys and hold them until full load apparatus. After this, you can perform the above steps again.

Removing viruses when connected to a PC

Now let's see how to remove viruses from Android via a computer. There shouldn't be any problems here. Simply connect the device via a USB cable, having previously enabled debugging.

Windows Explorer will display two drives (internal and external). Via RMB on each of them, simply select check using the command line of the installed standard antivirus. If this does not help, use portable utilities that select media as objects to scan.

Resetting settings using the standard method

Finally, a few words about how to remove stubborn viruses from Android when none of the methods proposed above gave the desired effect. In this situation, only a complete reset or flashing the device will help.

In the very simple case in the settings section you need to select the appropriate item from the menu Reserve copy and recovery, wait for the process to complete and reboot the device.

To restore the factory firmware, as they say, from scratch, you can use specially developed utilities. For example, for Sony it could be Xperia Companion- an application installed exclusively on a computer or laptop. You can also find utilities for other models this kind of. You just need to visit the official website of the manufacturer and download them from there. This process will take more time, but you can be completely sure that after this the user will receive a phone or tablet in the same condition as if it had just been purchased.

Hard Reset

However, if such methods do not work, you can perform a forced reset, which is called Hard Reset. Login Recovery menu is done in different ways (mostly holding down the volume and power buttons). However further actions are the same.

In the recovery menu, you need to select wipe data/factory reset and wait for the settings to be restored, which is similar to formatting a disk in regular computer systems.

Brief summary

As you may have already noticed, there are a lot of ways to combat malware. It's hard to say what to use. It all depends on each specific case. But most effective method, if the user previously made a copy of contacts or some other important information, of course, is to return to factory settings with complete removal all information from mobile gadget. But this, so to speak, is the most radical method.

In simpler situations, if you can still install anti-virus software, you shouldn’t neglect scanning utilities either. At least bear the strain on system resources during the verification period is possible. After neutralizing all the threats found, there is nothing easier than simply removing the unnecessary applet, installing instead at the input some more lightweight scanner like McAfee or 360 Security, which will not particularly affect the performance of the system.

However, there are enough such programs even in the Play Market, not to mention their a huge number in the Internet. But it is strongly recommended to download such utilities exclusively from the developer’s websites, since on other resources, strange as it may seem, along with the antivirus you can also catch a virus that is initially built into the shell installation file APK, and then activated in the background when installing the main application.
