I have been using norton internet security for several years. Each year I have purchased a new key from a retail source (usually amazon), and entered this after clicking the renew button. (Last year I purchased a NIS key for 3 products for a single user.) I have found this to be cheaper than purchasing the key online from symantic and easy as it does not involve any actual uninstall or reinstall of the product. I am not sure what product is actually now running on my PC, as sometime during the last year it updated automatically and the interface now looks different although it still bears the title norton internet security.
I note that retail sources no longer sell norton internet security, and are only selling norton security. Please advise whether I can purchase the key for norton security (from amazon) and enter this after clicking the renew button as before. If not then what is my simplest and cheapest renewal option.
