SUPERAntispy - You were right, it must have been a trace. Just for the hell of it, I uninstalled and re-installed Spybot and it no longer detects Smitfraud, Torpig, or Virtumond, which were the three it was detecting and couldn't eradicate.
It seems that SAS was able to fix all the problems so Spybot is OUT an Superantispyware is IN!!
So it gets a huge "thumbs up" from me and having purchased the full edition I would recommend it to all
Thanks for your help
