Often from users of smartphones on the Android platform, you can hear that their phone is constantly digging into the network, downloading some applications and installing them without permission. These can be absolutely any applications, but, as a rule, they initiate viral traffic and try to put a spy on the phone.
The problem of installing unnecessary applications is known mainly to owners of smartphones who purchased them in online stores or directly from China. These smartphones often have such problems out of the box. It is important to note that standard antivirus is not able to resist these applications, because their algorithm differs from the algorithm typical for viral activity. Those. the antivirus software does not detect them, since the program does not appear to be dangerous for it. Indeed, the only function of such a spyware is to go to a specific site where another malware will be downloaded.
The problem is dangerous for the user because such a program from a smartphone can easily or spend all your mobile traffic downloading some additional viral applications. Both of these factors are not desirable. Therefore, we advise you to use smartphones, the quality of which you cannot check and are not sure of the authenticity of the software and firmware only for entertainment and for games, and for responsible business use proven smartphones that are sold in official stores.
If you suddenly stumbled upon a smartphone that constantly installs applications by itself, then a firewall will help you. This application is able to restrict the access of all phone programs to the network and prohibit or allow specific activity. For example, in the case we are considering, a built-in launcher climbed into the network. As soon as you forbid him all activity and replace the launcher with a standard one, the problem disappeared.
… After all, many dubious applications often try to do the same actions that we described above. This wastes traffic and forces your phone to dig through advertisements or build Trojans.
As a firewall for the Android system, you can use the free application "firewall without Root".
This program does a good job with most of the functions. However, it would be very useful to supplement it with an antivirus program. DrWeb has the widest free functionality.
