Your computer has been infected with malicious software. Since you do not seem to be technically inclined, try these
a) grab a geek. This could be a technically inclined friend, or a guy from a paid service.
b) back up your data while you still can. I cannot stress this enough. Copy all of your important files (pictures, documents, music, etc...) onto another hard drive (internal, external, UMS-enabled iPod) or flash drive. This way, if worse comes to worse, you will always be able to wipe your computer, reinstall everything, and still have your data.
Though there are many ways that you could have been infected, the majority of such infections comes from torrenting files (uTorrent, Limewire sound familiar?) and visiting objectionable websites *ahem*
