help with removing adware-abetterintrnt.gen.a?

Ok i’m cleaning up a computer for a friend and so far everything is going good. One problem though… adware-abetterintrnt.gen.a refuses to remove itself…i’ve scanned the system with mcafee and it picked it up and i hit remove and it said it couldn’t and that i should try to remove the software manually. the only problem is that there isn’t any funky or weird software installed on the system…i removed it all. there is hardly anything on the system at all… i scanned the system with mcafee (which is the only software that picked it up), spybot search and destroy, and adaware … any suggestions?
