I posted a reply to your post, but guess it timed out and disappeared, so I'll try this again.
No have not uninstalled Norton yet, as I am not at the shop where problem computer is located. I will be there Monday. At that time I'll select one of the options for Free AV you guys gave me and install it.
I am a sponge for this computer knowledge you folks have. I will listen and learn as much as I can, and I am willing to take the cover off and do whatever you guys tell met to do.
It's perplexing because its been going on for 2 months, and I have gotten nowhere.
It apparently is not viral, so what the heck can it be? Any ideas?
