    Hopefully someone can help me, as this is relly beginning to p**s me off !!!

    I ran a virus scan of my PC recently and found a Tojan virus. I used Norton AV an a symantec removal tool to eventually remove this virus. When i rebooted the PC it reported that the WIndows Activation staus had been disabled. I rebooted in SAfe Mode which did give me access, but it wouldn't allow me to Re-activate the OS. I decided to bite the bullet and restore to factory settings. Now when I reboot, it tells me that the Product ID is invalid!!!

    Can someone please give me some pointers as to who to resolve this.......its driving me nuts!

    You could try the phone activation method and chat to a ms rep. i'm sure if you explained the situation they would give you a new key..
