Incredibly Annoying Notifications

I have looked through every thread here and do not see anything that provides an answer. Please answer.

I get huge, annoying notifications from Norton every day. They take up about 1/6th of the screen. The worst one constantly asks me to install a toolbar that I don't want. This is out of control. The product is not usable. I used Norton 5 years ago and left because of this annoyance - thought I'd try it again and it is even worse now. 

IF I AM PAYING YOU FOR YOUR SOFTWARE, DON'T BUILD IN ANNOYING FEATURES I CAN'T TURN OFF TO SELL ME ADDITIONAL FEATURES.

It is awesome how you don't have any labels about misfeatures so the "community" can't work on solutions together.
