Getting closer to the answer. I disabled the overnight Norton scan and my IE10 username/password info was intact this morning.
After posting at the Norton forum to see if anyone's seeing similar issues with their Norton utilities, a member posted suggesting that I disable my Norton "remove tracking cookies" option when I run the next unattended scan.
I'm still not sure what component of the Norton scan is removing the IE10 password history but process of elimination over the next few scans should nail it down.
