Be aware that it could be a marketing ploy to get you to purchase it, Clive. I firmly believe that some programs 'plant' their own 'spyware' on your PC, in order to scare you into buying the product to remove it. Spyware Doctor is a very well regarded application, but it seems coincidental that it found all these items, at least 4 other programs missed.
Oh, I just re-read your post - have you run all the other utilities on Mrs Clive's machine also?
