Download AVG AntiVirus Free

The biggest leak with this Android antivirus tool from AVG is that it is contaminated with ads. They work on almost every screen, and you're always just one touch away from upgrading to the pro version of each app area, which is frustrating if you accidentally tap it.

It's also annoying when AVG finds risks that aren't really abusive. However, if you like these types of alerts, even if you haven't found any of your files or apps to be harmful, then you won't have a problem with it.

For example, after scanning, you may be told that the "unknown sources" option is disabled on your phone, which usually shows when you have installed an unofficial application that may contain a threat.

Although this feature may always need to be enabled, disabling it is not necessary, meaning that files are currently being attacked or infected.
