Several weeks ago, avast! released a beta version of its mobile security and anti-theft apps (the latter of which used to be Theft Aware) that brought with it a slew of new features, as well as an all-new web portal. Those new features have now left the beta stages and the final release of version 2 is available in the Play Store.
This is a pretty major overhaul for what I believe was already among the best anti-theft/anti-virus solutions for Android. I've been using the beta over the last several weeks and the web portal is comparable to the best that I've ever used, which includes most paid services.
