thanks for the info. I running 4.0.1 also I hate Internet Explorer. their is a program called combofix
that will clean up most bugs. just make sure you download it from bleepingcomputer.com or it's a fake.
your friend could also boot up into safe mode and run his antivirus software to try to clean it. don't just do a
system restore to a previous date because that will do nothing it will come back.
at least his on the power tour more fun than a computer
