Expiring and constant reminder

My Norton internet security expired looooong time ago and i didnt want to renew it since it was a free trial that came with the computer.

Now whenever i turn my computer on a window pops up reminding me to renew or I can pick ''remind me tomorrow'''. This is the most annoying product I have ever come across. There are no option where I can choose ''dont remind me again'' or something like that so everytime I turn my computer on I have to live with that pop up. 

This is the worst I have ever tried. You may think its a small thing but Im sick of this. Im even close to comparing this to a virus itself.
