Blue Sky Thinker
I have used RegSeekers 'Clean the Registry' feature to se whats there and believe me there is a lot of stuff CCCleaner has missed. I will delete those entries first and see how my PC reacts over a few days and then get down to the Symantec/Norton problem.
Couple of things, where does the RegSeeker put the backup files? And, I did run the Norton uninstall (designed for their 2003 to 2007 programs) and my problems are still being logged on start-up in the Event viewer, so this utility does not work.
