With the recent rash of viruses and malware in the Android Market, more attention is being paid to the need to protect mobile devices. A recent free application is Lookout Mobile Security reviewed on InformationWeek . I have to say I am still partial to WaveSecure, winner of Software of the Year 2010. It does everything that Lookout does, with additional features including tracking, buddies and better updated virus information.
Full Disclosure: I am employed at McAfee who now owns WaveSecure.
Whichever app you decide on, it is obvious that people can no longer wait to get protection on their mobile devices. Not to be “Fox-ish”, but you may already be infected and should at the very least, download a free trial to ensure your device is not compromised.
