can't remove Norton download manager pop up after upgrade to windows 10

I started with N360 on windows 8.1.  Upgraded to Windows 10. Now I cannot get rid of pop ups asking to reinstall N360.  I have run the removal tool and still I get the popups.

The pop up process is running out of C:\Users\Public\Downloads\Norton.  I can kill the process, delete the directory and another one gets created.

How do I get rid of N360 once and for all.
