Can Someone Advise Me How to Stop Norton 360 from Bugging Me with Ads

I am getting rapidly tired of being nagged by Norton 360 to pay for additional features. Is there a way to disable these constant begging letters ? I have paid for the software I wanted. I can appreciate getting one Ad to let me know that I can pay for some other feature but then that is it. I want to say "No and don't remind me ever again" and NOT BE reminded ever again.

I regularly clean my installation with Privazer and maybe that is deleting Cookies so that Norton's thinks it needs to have another go at me. If so they need to build an "easy to find" request to "Unsubscribe" from any further advertising in the product itself and not rely on the absence of a missing Cookie . I am getting so sick of being hassled that I am seriously doubting whether I will bother paying for a renewal when my current subscription expires. If anyone can tell me if such a "Off" Setting exists I would be very grateful.
