How to remove viruses from Android?

Virus on Android Any electronic device that exchanges data, goes online and stores data can be susceptible to virus attacks or infection. A small amount of memory on your phone or tablet is enough for malicious components to work.

Types of viruses

Typically, malware is written to serve several purposes:

  • Obtaining personal information.
  • Theft of wallet and bank card data.
  • Sending sms to paid numbers.

Most popular viruses:

  • A fake for a well-known application. The name and logo of a popular brand are taken to create, but the application contains only malicious files.
  • Trojan. Fraudsters enter code into the application, and all actions look like the program is running in normal mode. In fact, the Trojan remembers all your passwords, card details and other personal data – and sends them to the hacker without you noticing.
  • Banner. There is a message on the smartphone screen that does not allow using the device, with the requirement to pay a certain amount to unlock the device.

How do viruses get into the phone?

There are many ways of infection. Most Popular:

  • Downloading and installing third-party applications (not from the Play Store, which has its own built-in antivirus).
  • Receiving sms, mms, e-mail messages that contain a link to an infected site with a virus.
  • Data exchange with other device users (via bluetooth or Wi-Fi).
  • Using public Wi-Fi, for example in a cafe.

It is difficult for an inexperienced user to recognize virus files. The first call is a request for a paid action.

Thus, all paid messages sent are approved by the user. This is done by scammers who legally steal the subscriber's money.

Another sign is excessive battery consumption and Internet traffic. The program in the background performs actions to transfer data about the owner of the device.

A freeze on a smartphone can also be a sign of infection. The virus needs some kind of RAM to work.

The most obvious manifestation of the virus is a banner that blocks the owner's actions.

Payment of the declared amount does not lead to a solution to the problem. You need to remove the screensaver yourself.

If the virus is aimed at sending paid SMS messages, then the balance of the SIM card is quickly reduced. In the case when auto payment is connected, this can lead to serious financial losses. The program blocks the consequences of its actions. Messages from the bank or operator are not shown to the owner of the device.

We should also highlight online viruses.

During this time, attackers will try to achieve what they want.
