Well, all of my scans came up with nothing. As far as my computer is concerned, there's nothing wrong. Unbelieveable! Well, I've gone into the browser options menu and blocked all cookies for clubrewards (since the address of the shortcut is http:// clubrewards.myregistration.com) and I've added a new entry to the ad-blocking extension for my browser (and I block Java and Javascript by default), so hopefully that'll take care of it. Everyone might want to do the same to be on the safe side.
