Update your antivirus (AV) program & scan your computer. If your AV isn't finding a problem, try one of the online scans in this thread: * WARNING: Viruses on network you should be aware of ! *

Or try one of the freeware programs here (Avast, AVG Free & Avira are all well known AV programs): http://www.gnutellaforums.com/window...tml#post330543

Always make sure that you're using a good AV program. Keep it updated & use it to scan all files that you've downloaded - before you open them!
