Hi Grumpy181155.
So I gather that you have "Backup" and "Backup Status Overlays" unchecked on the "Settings" page, have deleted the "N360_BACKUP" folder from you D drive, and rebooted. But you still have the "Norton Backup Drive" showing under "Other" when you call up "Computer". This sounds odd, but it may not be an issue as the "Norton Backup Drive" should be empty. Click on that icon and see what is shown as being inside it. There should be nothing.
I await your response with interest.
