SP2 plays with the tcp/ip network stack as well. It broke a whole lot of IPSEC and SSL VPN clients I use.
For ultimate security at SOHO price, I have a Sonicwall TZ170 with IPS, Gateway AV, Anti-Ad/Spyware, with McAfee on my PC (managed via the Sonicwall - if AV isn't up to date you can't get to the net, if theres a massive virus outbreak it stops all PC's accessing the net until they have the DAT for the outbreak), and PestPatrol which I use to scan stuff from time to time.
My adware/spyware picks droped from a few a week to zero a week.
Spyware is pissing me off, today I needed a filejoiner so I googled and tried to download a couple of small "freeware" utilities:
