I run on my main computer : Kaspersky Anti-hacker (firewall) Wormguard (Diamonds CS) EAZ-FIX V8 (ISR) IE7 (browser) XP-Antispy ( http://xp-antispy.org/content/view/12/40/ ) Email > Live Mail (hotmail) scanned automaticly with Trendmicro. > i'm using this setup for a long time, although before EAZ-FIX i used Deep Freeze, but didn't like that i can't reboot to test software without losing all changes. I also keep full image backups (not snapshots) on external media. I made the image's with EAZFIX. But i never needed to use them. NEVER had any kind of infection (besides the ones i created myself for testing). It seems DeepFreeze & EAZ-Fix seems to provide enough protection. Although i'm aware of ISR limitations against MBR infecting malware.
