I need help, ad ware possibility blue font links

Hello, this is my first post on this site sorry if this is in the wrong spot.

 

i have norton and i think i have adware that its not detecting. my problem is randomly when i go to a website some words will be underlined with blue font, and they will be a link to some random site with random links related to that word. i read online that this is adware generating revenue to that website. 

if someone could confirm that this is adware, tell me how to rid it, that would be fantastic. 

 

i also tried the option "if you still think there are risks, click here" after i ran a scan, i downloaded and ran another scan with that and it says its safe. this isn't a big deal but is starting to get very very frustrating now that i read it's a virus/adware.
