norton does still have a very bad rep as a slow mover
but you've been had (85 times) - the guy from TT knows what everyone else in the business knows ....
it's difficult to get rid of because that's it's job.
and because of that - Norton provide removal tools which do the business.

(it's the same for other packages as well - avg, avira, macafee all provide removal tools)
... I've used them to remove hundreds of expired copies ... we've recommended it here many many many times - and they are all free to download.
they don't always wear a mask it seems
