You can perform analysis of all applications installed on the card and memory, as well as real-time analysis of the apps when you first start. You can also schedule scans, update virus protectors, uninstall applications, delete files or report a false positive.
Other features of the application include a firewall, a web shield and a call and message filter that will allow you to send calls from some numbers directly to your voice mail or to spam.
However, although the online threat protection is fine, the best feature of avast! Mobile Security is the anti theft system, that allows you to hide the application from a potential thief so that the person can not find it and delete, and locate or lock your phone remotely at will.
avast! Mobile Security is one of the best and most complete protection apps you can find on Android OS.
Requires Android 2.1 and up
