bitdefender/norton etc

[Gdeaver]

Norton Internet security 2008 was a resource pig. Norton internet security 2009 is MUCH improved. However most of the improvements rely on at least a dual core. Forget norton 360 or just the AV. Newegg has the IS disc only for system builders for 29.00$.

I second the "Use AVG Free" ... It is what i use (i run Vista Ultimate SP1), and i use that along side Windows Firewall, Windows Defender, and UAC (yes, i actually leave it running). I have yet to get a virus/ad/spyware/ and my PC preforms pretty well for what it is (Pentium D, 2GB RAM)

Hope this is helpful
