Malware bytes was the ONLY software I found that would effectively remove all the crap and pesky Trojans that would not be erased by other software. I keep it on the desktop and run it every few months. There is another good simple DOS one for Trojans, cant recall the name as it is a funny name...and its on my home unit...I'll try to find it...all freeware.
DO NOT search google for freeware clean up utilities, many are worse than the affliction and add more then make you pay to remove em!!! Bastards!
