I also tried contacting Symantec and was not satisfied by their response but, I think I may have found an answer to the ALEUPdate.exe conundrum.
ALEUpdate.exe is the automatic update process of Norton that is always searching for updates to NAV and other Norton Utilities, similar to Windows Live Update, which is always on (SVCHOST.exe!)
You can turn off ALEUpdate.exe.
Go into the Control Panel and right click on the Norton Icon
Find the tab for Live Update and uncheck the box
Then you can either got into Task Manager and have Live Update run on a given schedule (not at Start up or Log On), and/or you can manually run Live Update after each time you log on to acco8nt for any viruses that may have developed over night!
I've done this for two days and things seem to be running much smoother
You may also want to turn off System Doctor at Log On, and then manually turn it on after your PC is booted up
