OT: AntiVirus Software

I've been a faithful Norton user since 1999 and it has rarely ever given me any problems. When something did manage to come up, the techs were always helpful and courteous.
In the last few weeks, I've been assembling parts for a new PC that'll be dual booted with Windows XP Pro X64 and Vista 64. I've found out that Norton does NOT support the XP X64 at all, but does support Vista. So... I've been comparing and shopping around for other Antiviruses, including AVG and Nod32, and finally decided on Kaspersky Internet Security as it supports BOTH the OS's I'm using and their tech said I'd only need one copy instead of 2 for my system since it's ony 1 machine. I also found out that compared to other AV's out there, the Kaspersky takes hardly any resourses to run itself whereas my Norton was a hog, and McAffee has way too much crap going on at once.
After doing all the comparions to the other Antiviruses out there, this one ranked in the top 2 for almost all of the online sites I checked out. BitDefender ranked ther other, but doesn't support anything 64 bit.
