Just an FYI TDS-3 is no longer
http://tds.diamondcs.com.au/ In most reviews I read they scored best or close, usually with Trojan Hunter, which I use. I did try and use TDS-3 which I could neither confirm nor deny its effectiveness (free) but liked the options. I did try Kap and was thouroughly impressed, but it did not get along with some other tools I was using and I never found lasting keys/serials and chose free over quality and repeditive licensing.
I do really find it effective, while tedious, the use of DiamondCS ProcessGuard and WormGuard. With a couple tools from systernals (Regmon, ProcessXplorer, and PsList)to catch most anything (outside of rootkits which rootkit killer is great....I think?)trying to intrude upon my system. As far as AV I have tested a lot and still think NOD32 is the best, years of tests and proof to proove it

BTW Exellent article find KennyL, thanks.
