I've got 2 NOD32 licenses, which I've not used for a year or so, and I've not checked to see if they've expired.

We got a minor USB key virus at work last week, so I'm thinking of putting AV on my home PCs. There are four (other than the Linux virtuals): 1x Windows 2003 x64, 2x Windows Vista (both currently x86, but I think I might move one of them to x64 this weekend) and 1x Windows XP, which the wife uses. Oh, and the media center, but it's got a dead video card (again), so I'm going to trash it.

Is NOD32 still the best? Given that the Windows 2003 x64 box is a server (and I don't need on-demand), I could install ClamWin on that box -- does it support x64?
