Norton protection

not to be mean, but I'm confused

 I Like Norton products and trust them to keep me fully protected.

 

however, it seems like many many times on here I see people having to install malewarebytes, or spybot, or superantispyware to fix a problem that Norton should be able to take care of. i know that one product is  not always able to do it, but jeez it seems like anytime there is an issue, the answer is to download one of these freebies. Is that why i pay $60  a year to norton, so that i can get the problem fixed with a freebie??? I know it sounds like I'm being mean, but not intending to. just confused
