Great review of the latest in Android Mobile security.  Best of all.. It’s a FREE download.
 Currently in BETA, this is clearly the front running in protection for your Android Phone.

Avast! Mobile Security BETA, includes the strongest set of features we’ve ever seen for a free security app. Besides the usual automatic virus scanning, it offers a firewall (rooted phones only), GPS tracking, history wipe and web shield.

One of it’s strongest component, is the stand-alone Anti-Theft module, once set,  allows it’s owner remote features such as raising an alarm, locking, locating, memory wipe and restart as well as as the ability to establish specific whitelisted SIM cards (others won’t be accepted). It can also protect itself using advanced techniques so it becomes impossible to remove the app unless you yourself use even more advanced removal techniques.

This app clearly is the Front Runner in security for your Android Mobile Device.
