ok i was playin a game online and someone told me to download this program, normally i would never do this but it was diablo 2 and there was hype about a new upcoming dupe so i fell for it and dl'd it and opened the file

after a few minutes all my exe files started messing up, windows could not find the path of any exe files. i scanned the file before i opened it with norton, nothing showed so i thought there was nothing. i cant get in regedit so i cant delete the entry. can someone help me????
