I got something similar recently. I was searching for some antispy software for a friend of mine and came accross a site (can't remember the linky) stating that my windows was infected with all manner of things. It urged me to click a link to scan my PC and free it of these terrible nasties. Out of curiosity I did. Moments later the site informed me that many of my windows system files were infected and helpfully gave me a list of the offending entries. This was interesting since I am running linux and don't have any of those files! So I guess the fable is be careful what you click- a lot of the time it's a scam as pointed out!
