Piece of advise, DON'T EVER surf the net without an anti-virus installed in your pc. Try using Kaspersky Internet Security 7 for safer internet surfing and please don't use IE browsers cause you will be more prone to viruses, try using Firefox 3.

Type in Norton Online Scan in your search bar. Go there and allow it to scan your PC and see if you have been infected. Your PC should not be on the Internet without some kind of virus protection. http://free.avg.com/
