Ha! Touchet!
Another sign to type properly - I see CDS, and I presume it is abbreviated; not expecting CDs. But it is as much my fault as yours, so who cares!
You have a point about CDs; but you'd presume that the creator of the virus would not just settle to crash all Windows Computers and then stop - anybody who would take the time and effort and obviously money to write a virus so terrible it would take down most Windows PCs would not just stop sending it out - or make it so it doesn't duplicate itself. It'd probably stay in the PC and crap up the new installation, etc, ect and so on.
But its all just hypothetical; it would never happen because its a physical impossiblity! Although - it would make my job far more interesting if it happened in about 7 to 8 years!
