Atribune.org makes some really great free tools. Just a few that I use on a daily basis:
VundoFix – The Vundo Trojan can be very hard to get rid of. I’ve been 100% successful in removing the Vundo Trojan with Atribunes VundoFix. Please note that VundoFix should be run from SafeMode.
ATF – Cleaner – ATF cleaner clean ALL temp directories in Windows at once. It’s super fast…luv it.
