Ask an avid desktop Linux user if he or she (ok, he) uses an antivirus solution, and he won't give you an answer, he'll give you a sermon. And while his zeal might be inappropriate, his sentiment will be largely correct: Linux really doesn't need antivirus software. Android, with a smaller market share and simpler guts than most common Linux distros, has even less to worry about — which is why it's completely absurd for SMobile systems to release VirusGuard, the first antivirus software for the mobile platform.
The software claims to be able to scan devices and their memory cards for over 400 types of known malware, none of which, as far as I can tell, are harmful to Android phones. Now, it's not impossible that dangerous malware could find its way to you G1 in the future — in fact,Android has already experienced one security scare — but installing a piece of software that scans your device for Windows Mobile virii won't do anything to stop minor exploits like that, which can be quickly and effectively patched anyway.
Of course, all this security talk could just be there to provide parents with excuse fodder to install this on their child's G1 — it also monitors voice and text communications. Anyway, VirusGuard is already available on Handango, but will make its Marketplace debut when Google finally enables its payment system in Q1 of 2009. You misguided peace of mind will cost a whole $US10, by the way. [Android Community via Slashphone]
