My norton

I have had NORTON for 14yrs its now NORTON 360 .  The cost has increased considerably but I have gone along with it knowing I felt safe.   My renewal is due in December, yet I am continually being told I should download more protection.  I don't have a lot of family members sharing now just 2 of us. So I am wondering if I should look for some other protection?  

Why is Norton always trying to get me to spend more money on new protection half way through my annual subscription. I can't afford to buy even more, 

Any help would be gratefully received.
