With Systemworks, when it is all up and running well, it is a very good program (but dont get too carried away).
Unfortunatley, when things go wrong there are so many files and folders scattered around your system that it is a complete nightmare to get rid of them all. This, added with the fact that most of the files will load at startup means that even if and when you do find them you cannot delete them.
It drastic I know, but having had many problems with Systemworks I strongly suggest that a reinstall of Windows after a full format may be a sensible option, at least that way you know you have got rid of all the offending files and can reinstall your programs after systemworks with the AV turned off.
Sorry not to have any better advice.
