Ok so my girlfriends laptop has some kind of virus. The windows 7 security thing keeps doing some kind of scan and it's finding a bunch of infections and some of them worry me because they are named like blaster worm, Trojan something or other and the one I'm most concerned it's saying child porn with a bunch of other numbers. The security thing won't finish the scan before the computer starts to go crazy with warnings and I can't open the Internet or anything to download any kind of anti virus shit. Any advise or no what this is? There is Also an icon on the desktop that says protection something that wasn't there before.
