A couple of questions.

Should I uninstall everything McAfee: Security Center, Virus Scan and Firewall -OR-

Should I leave Security Center and uninstall the other 2?

I know these programs can be picky about leftovers from uninstalls. What is the best way to get a clean uninstall or is it even possible?

The only place I found a choice about uninstalling was in Add/Remove Programs

If I can’t get a clean uninstall this way, what else do I need to do?
