@ Elon - You could have booted in Safe Mode then ran those programs..
It most likely would have gotten rid of it then.
(Press f8 when booting up on most computers)
Also, Security Task Manager does a great job of closing down those programs so you can remove them with the Adware/Spyware removal programs. (Link to Download in "HL2 F*cked" thread, or in my journal)
@ Trapt - I wouldn't recomment Hijack This to n00bies, you can screw up your computer if you dont know how to use that program. Whats CW shredder, is it some kind of Cookies/History Clearing program?
@Habboi - Go to Start > All Programs > Startup and get rid of it from there, its easier than going Start > Run > Msconfig and using this Microsoft Utility.
@4thGen - Of course Vista is Insecure, they found over 40 serious security flaws, before the beta even was released.. and Its a resource hog, I wouldnt recommend using any less than 1.5 Gb RAM on a Vista machine. One + is that it supports 64 bit processing, so you can finally make use out of your AMD 64.
@all - The moral of this story is - Don't let your Mom look at pr0n on your computer.
