My last computer was infected. I've built a new one with pretty much everything brand new except I'll be using the same windows 8 CD and product key as my old computer. Could this infect my new computer? Sorry if this is a dumb question.
Your first comment was that you were re-using the same CD that was used on the infected computer, and not just the key; This could be a problem: Where did you get that Windows 8 CD?
