Windows Vista AntiVirus program will not go!

When looking in Control Panel/Security Center/ I have noticed that under Malware I have 2 AntiVirus programes running (it is advised that you only have one active) one being McAfee which I wish to retain but it also shows "Spyware Doctor with AntiVirus" and as far as I am concered this was uninstalled over a year ago, so how can it be seen as an active and up to date AntiVirus application.

Searched registry under program name and the company that produced it called PC Tools (also checked PC Tools website for uninstaller but no luck) and it does not exist in the registry also searched Hard Drive(s).

Anybody now how I can remove this from the Security Center?

 

I carried out the tasks as described, and yes Spyware Doctor has gone, but so as all of my other settings for Spysweeper and McAfee it is now telling me that I have no Firewall or AntiVirus? They are in fact running okay it is just the Security Center's method of reporting again.

How do I get these back?
