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.

  • 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 third.party 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.
