Norton is spamming requests at me to install it's toolbar.

I just got a 1-year subscrption to Norton (a real one that cost me 90$, not one of those that comes pre-installed on your computer), I got sick of Avast's spam and weird results.

Things look good, but about 2 or 3 times a week a pop-up appears in the lower-right of my screen asking me if I want to use the Norton Toolbar (I don't).  I see there's a "Don't ask again" option, which I click every time, but the pop up always comes back... How do I stop this pop-up?  It's getting really annoying.
