How to find and delete viruses on Android phone

Modern phones have long ceased to be a common means of communication. We can say that they almost completely replaced a desktop computer or laptop. From the smartphone you can go on the Internet, find out the necessary information, send a message and even pay for the goods in the store. However, attackers also keep up with the times and try to take possession of a person’s personal data, creating harmful software and phishing sites. Let’s look at how to find and delete viruses on the Android phone, and we’ll deal with their varieties and features again.

To date, there are a huge number of different viruses, each of which is designed to obtain certain information. We offer to consider their varieties in more detail using the list below:

  • Fakes. This type of threat is disguised as a conventional application, in the role of which the social network or messenger most often acts. The unsuspecting user uploads anything and sets a dangerous program on his smartphone. Nothing happens until the start of the launch, but after it the system begins to collect the information laid in the code. It can be bank cards, photos, text files or saved passwords.
  • Troyans. This is one of the most dangerous forms of mobile viruses that does not give itself out of virtue. A special code is built into the frequently used programs, and then collects the necessary information and transmits it to the attackers. This threat is able to intercept presses on a virtual keyboard, Wi-Fi password and account data.
  • Advertising virus. Such a threat is the most harmless, since it does not cause any harm to the device. However, permanent advertising banners can slow down the phone, which leads to uncomfortable work.

If desired, special subcateuria can be distinguished, but for the general familiarization of the information given there will be enough.

How to find out that the device has a virus

Sometimes it is difficult to determine that the virus has appeared on the device. However, based on a number of signs, it becomes much easier to do:

  • From the account of the mobile number, funds began to write off quickly.
  • Unknown applications are installed on the smartphone independently, the design of the desktop changes, Wi-Fi, Bluetooth and other functions are automatically turned on.
  • During operation, advertising banners periodically pop up or videos are launched.
  • When trying to unlock the phone, a message is displayed on the screen stating that you have committed an offense and must pay a fine.
  • Antivirus for no reason left or simply stopped starting.
  • Unknown programs began to appear in the list of advanced processes that you did not install yourself.

The list of possible signs does not end there, but the main part was presented above.

If advertising and overlapping messages do not allow us to work normally with a smartphone, then it does not matter. In this case, you need to reboot in safe Android mode. To boot in safe mode on Android, you need:

  • Call the shutdown or reboot menu (press the shutdown button for a long time).
  • The menu with the buttons of shutdown and reboot will appear. In it, click on the point “Turning off” for a long time.
  • A message will appear about the download confirmation in safe mode. Confirm the OK button.

Safe Android mode is a condition where you can use the system without all applications. That is, those same advertising banners and messages in it are not shown.

Go to settings → Safety → Device Administrators. All the programs that have the rights of the administrator are shown here. If there are any suspicious malicious ones, then remove the rights from them.

After that, go to settings → Applications. We are looking for all potential malware there and delete. After that we reboot again, but already in normal mode. Everything should be in order, and if not, then read the instructions below.

  • We connect the tablet to the computer, open the tablet memory. We find the folder where the applications are, for example System/App, and remove everything suspicious, after installing which the problems have expectedly began. T.e. In fact, we delete the ARC application through the computer.
  • If these options did not help, only one thing remains. Hard Reset. What is it, and how it is done. described in detail here. I will say only one thing. having made a general discharge, all the data from the tablet will be erased.

How to protect yourself from viruses

It is easier to prevent infection with viruses than to “treat” from them later. As they say, God protects and God.

  • Download applications only from a proven source. from Google Play. Although, as practice shows, and there you can pick up the infection, but this happens quite rarely.
  • Therefore, it is recommended to install a free, but good antivirus on Android. It will prevent the virus on the tablet.
  • Do not put a checkmark without particular need, opposite the “allow installation of applications from unknown sources” in security settings.

And remember, ruttered tablets (which are established by Root Rights), are much more vulnerable to a viral attack. the virus comes to the tablet with Root Rights, as to his home, and receives control over the system.

  • Check the rights of the application: it doesn’t matter where the application is downloaded from, before installation it is necessary to check what functions and services it requests access to access.

You should be alert if the video player for some reason requests access to contacts.

Accordingly, it is worth giving preference to the manufacturer who regularly produces updates for his device (for example, Nokia).
  • Install antivirus: Android can do without antivirus, but those who are worried about how not to pick up the virus will be clearly calmer with it. Also, antivirus applications, as a rule, in addition to the main, have several more additional useful functions. Keep in mind that the antivirus on Android may have false triggles that you can not pay attention to if you are sure of the cleanliness of the application.
