Norton 360 on Win 7 requesting System Restart Needed many times in a day

Norton 360 on Win 7 stating that a "System Restart Needed" over and over in a day. It's about every hour or so, the time between requests for reboot varies. A feww times it said that it found a couple dll's which were for Google Chrome. I have been a tech for many years so I'm very careful not to get infected. I've tried all the scans with Norton 360, after more research I tried other things including other programs, i.e. Advanced System Optimizer, Malwarebytes, Hitman Pro, Kaspersky, I've not found anything infected, no malware, etc..
I also used the Norton program to un/reinstall Norton 360. Thought that did it but I just received another request to reboot.
Any hint would be appreciated.
