Norton NIS won't delete from my Norton A/c

I received a reminder my NIS subscription expired in three days and to renew using the renewal link. I'd purchased a Norton Security Key card previously and entered the key  but this was rejected. I decided to uninstall NIS with the Norton Removal Tool and install Norton Security via Norton.com/setup as instructed on the card. After a few hiccups this was registered and operational. After the expiry date of NIS I had a look at my Norton A/c and Norton Security was listed but in addition NIS was listed as expired. When I tried to delete NIS via the waste basket icon the deletion was rejected (see attached file). It seems there must have been some residual entries left on the register from NIS. Every time Windows opens I get the chime like a horn going for intermittently for approx a minute as if something is trying to load. As I can't uninstall NIS by Windows "Uninstall a Programme" will I have to remove Norton Security with the Norton  Removal tool and re-install to remove NIS from My Account and stop the chiming?
