a big thanks to whoever makes the malware removal programs

just wanted to say thanks to whoever wrote those removal programs, combofix and the mgtools one, they work great! thanks.
btw i had a problem with someone's computer, loaded with malware, avg and spybot took care of most of it, and i have a little know-how with hijackthis, but even after i ran those, i still had problems. the control panel was gone. and i kept getting messages saying something like " u do not have permission to do this..blah blah blah. but i ran combofix and everything is fine now. ran followup scans and nothing is ther anymore.

thanks.
