Hey -

At last one I can really help with! I'm a professional software engineer working in anti-virus and security technology for a while now, so while my info isn't definitive, it's at least well informed.

Try these places to scan for viruses:

http://www.pandasoftware.com/activescan/com/activescan_principal.htm
http://housecall.antivirus.com/housecall/start_corp.asp

both of these are kept current with up to the minute updates of the signature files - I like the Panda one, I think it's a bit more complete but the Trend one is a bit faster. Both are excellent scanners and both have good AV researchers.

If you are infected there are several current viruses out there that disable installed AV software, so once you get out of date and are infected with one of these guys updating at that point won't typically restore your AV to running condition.

Generally one of the above will detect and may be able to clean but if not the best bet is to carefully copy data and reinstall the OS. Once that is done install an up to date AV and then scan each backed up file before restoring it.

What is the URL you're being directed to? Add spaces or something to keep someone from accidentally linking to it....
