I am two weeks into Windows 7 beta testing and have run into some issues finding a decent Antivirus that works. 
Of course I did some searching and read on the windows team blog.
Looks like nod32 as well as Free AVG works. Norton 360 is on a trial basis.
Guess my big issue is that all my beta testing and eventual purchase of windows live one care will not work on my Windows 7 Beta install.
Please Microsoft Windows 7 team talk to the OneCare team and lets see if we can get a workaround.
