Playing an internet game I managed to get a clever virus on my pc. It labels itself as Antivirus XP 2008. After a quick internet search I found that it pretends to be an antivirus program and tries to convince you to purchase its software to rid your pc of viruses. I downloaded McAfee Internet Security and did a scan but no avail. I've tried deleting it multiple times (did a search of my hard drive and deleted all traces of it that I could find and emptied my recycle bin. However after resarted my pc it appears again. What can I do?
