Process gaurd is also part of TDS 3, the best Trojan scanner around, that should be good.
I also use Bo-clean, Spyware blaster, Avast, Spysweeper, Trojan Hunter, and Admuncher. Usefull utilites when in trouble are Hi-jack This, XP Uninstaller by Macafee and Ads-alert, and Pest Patrol, and The Macafee Stinger updated weekly. Also go to the Update calendar for all your updates and definitions: http://www.dozleng.com/updates/index.php?s=920c98eb6fa3a4b501537d173e617788&act=calendar
