If you do have Norton Family installed, i would suggest you may have some corruption within your Norton product. 

 

Try clicking on Support - Get Support to run  Autofix to check your Norton installation and fix what it finds.

 

If that does not work, a reinstall of your product using the Norton Removal and Reinstall Tool will give you a fresh installation.

Download the Norton Removal and Reinstall Tool from here   www.norton.com/nrnr
If you use Identity Safe, backup/export your data. Use the CSV format for compatibility.
Run the Norton Removal and Reinstall Tool.
Reboot.
Run LiveUpdate manually a few times, rebooting as necessary, until no updates are available.
Try to log into your Identity Safe. If you can, you are done. If not, Import your Identity Safe data.
