AVG? Also I think Kasperky Labs.....been awhile since I went hunting for 64 bit, but I think I am going to install Vista 64 over the weekend to replace my 32 bit....
Kaspersky absolutely IS 64-bit Vista compatible. I just downloaded the Internet Security version and am using it right now on Home Premium 64-bit. So, not only is the AV compatible, all the other security components are too. Plus, right now you can get KIS and KAV on Amazon free AR, plus free shipping: http://www.amazon.com/Kaspersky-KAV...ie=UTF8&m=ATVPDKIKX0DER&qid=1196461546&sr=8-2
I ordered KIS but the delivery date was past the required rebate postmark date, so I canceled instead of messing with rebate companies. Someone talked to Amazon and they said they would provide a letter of explanation for the submittal...but that just sounds like a hassle to me. I ordered KIS 3 user Free AR from Frys (and got it two days ago) but that deal's dead now.

Above as mentioned...
However I myself have found AVG is not entirely 64 bit friendly on more than one machine... It works, but has some minor glitches here and there.
