Thank you 99charlie for all your time and ya your right it is a little complicating for me, that slave and master thingy always gets me confused.
Dearg Doom the computer is belonging to my father in-law and It was being used all along without anti virus and when I got him to put in avg and guided him over the phone.
It uncovered various viruses, and he proceeded to delete them I think, next thing I know he was getting the "blue screen of death" everywhere even in safe mode.
Any way since I've been talking to a friend who says he'll do it for me as much as he is sick to death of fixing computers at this stage.
He bought a Mac for the very reason so he says he no longer gets viruses.
