What do you mean by "wipe"? Was the drive formatted to remove everything then windows reinstalled? If not whatever you did is not what I would call a wipe. If you did then it's some malware I don't understand or it's a particularly nasty piece of work that made it into your motherboards firmware or into the firmware of something else.
Thank you for you answers. Yes, i did a complete wipe of the system (reinstalled windows). But i think i found what caused it and that it probably is a false positive!
