I got some good news for you, and for the rest interested in anti-virus protection for mobile devices.
McAfee has recently launched it's product Mobile Security, with anti-virus protection, real-time and on-demand, plus updates, for a variety of mobile devices.
You can find more info in: https://www.mcafeemobilesecurity.com/default.aspx
where you can download a free 7-day trial version and and later buy the full one on Android Market, or the correspondent place.
I hope you find it useful and give it a try.
