AVG antivirus & Security - Ensure complete privacy on the Internet, as it is very dangerous to be open on the network without any protection at all. Carefully scan your phone for intruders or viruses, view the most used applications, get rid of unnecessary programs that can even harm your smartphone, and, if necessary, turn on hiding photos by placing them in a special storage under a personal password. The app, in turn, can check Wi-Fi networks before connecting to them, so you have the option to use this feature too.
