<li>Uninstall the program using the add / remove program.  Reboot the PC.</li>

<li>Go to C:\ProgramData and delete "Norton" and "NortonInstaller."</li>
<li>Reboot the PC.</li>

This may change in the future.</li>
<li>Once this is confirmed, reboot the PC to remove all the old files (I know that upon engine changes, there usually have two files.  One is the old and the other is the new.  Only a reboot will get rid of the old file).</li></ol>
