I can't give you the best answer, but I use CA antivirus/firewall/antispam. It certainly does cause the computer to lag, but the windows vista anti-phishing filter is slow as well. I put up with it, as I experienced someone hacking through the windows firewall, and causing havoc with my email service. I still haven't sorted it out; and thank goodness I don't keep personal or banking details on my computer. Better to put up with the inconvenience than take the risk.

I actually have a lot more trouble with Vista 'hanging' for no good reason in web browsers (IE, Netscape and Firefox all do it).
