Avast! Introduces Free Mobile Security App For Android 2.1+.

There are plenty of free mobile security apps available for Android. The market seems to be filled to the brim with them. Yet it’s hard to say if they’re trustworthy because often they’re developed by companies that don’t have a reputation.

Fortunately, there’s now one more trustworthy free mobile security app on the market. It comes from Avast!, a company that has managed to successfully spread its name by offering a robust free anti-virus solution for the PC.

Avast!’s entry into the Android market is not a surprise, as they leaked details of their upcoming app back in June. The features available are competitive with other free security solutions. There’s anti-virus protection, a web shield that warns users of URLs known to contain malware, anti-theft features including phone location and SIM card change notification, and a “stealth mode” that hides the security app from prying eyes.

Perhaps the most interesting feature of all is the firewall that is available to users who own a rooted phone. There are not a lot of firewall options for Android, so this feature sets the app apart from many competitors.

Avast! Mobile Security is free, and there’s no paid version available. You’ll need a device with Android 2.1 or better to run it.
