Not sure, but things like this normally happen when YOU have a virus...
Endless stories of N00bs with laptops (Not saying you are) getting this sort of thing have come my way before, and I'm inclined to believe Tom wouldn't do something like this TBH...
Edit : NVM, I feel stupid now, 2 people..?
We're just working on this now. It's a problem with Canard PC - the ones who do the CPUID Forum Sigs to show CPU clocks, etc.
I don't think it's anything to worry about, but be cautious.
