Facebook somehow redirected me to a page telling me that my PC was infected earlier. Should I be worried?

[NONAME]

I'd consider myself to be an intermediate with PC's and I know that my PC wasn't infected before visiting this site. I don't know how, but my Facebook page randomly directed itself towards this site. I don't know if an application redirected me or if I accidentally clicked on an ad. It was the standard "your PC in infected. Click here to clean it" scam. I've just spent the last day and a half restoring my PC after a borrowed DVD-ROM (potentially) infected my PC. I'm just worrying now that I may have to start again. Could the site have infected my PC. Kaspersky hasn't found anything and it's usually pretty good at protecting my PC. Do I start restoring again, or leave it as is?

Also, I would post a link to the site (it's still in my history - no URL, just an IP address), but I don't want to infect anyone else, or get my Y!A account banned!

Thanks for any help!
