I just spent 3 hours removing 52 Trojans , dialers and other crap along with 7 viruses , off a old Dell laptop ,
including antispyware master , my prefered option was to do a clean full reload , it would have been quicker ,
but the laptop had no CD drive , and I was out in the field without one ," Hey I work for free just for the knowledge gained, " and a meal etc LOL ,
that antispyware master is one bad ass thing to remove , it locks up , ad-aware, spybot , and any attempted updates ,
I used a program called Supperantispyware
http://www.superantispyware.com/ in safe mode (F8 ) along with AVG antivirus , both free edittions , after 3 scans with both say the laptop is now clear ,
and also I used c-cleaner for a final polish up , ,
