You are referring to terminology created by Norton WinDoctor, so you'll have
to ask Symantec technical support for help. Or you can simply ignore
WinDoctor's advice, 99% of which is utterly benign and actually quite
comical.
If you are experiencing a particular problem with your computer, post it
here and we can help you. Otherwise, you can safely ignore toys like
WinDoctor.
