Elimination of Intrusive Internet Advertising

I am running Windows 10, and understand the plethora of annoying ads that pop up all over the place whenever I'm online.  I've learned to live with them, though it's gotten to the point where I'm willing to pay for a service that eliminates them (or at least most of them).  What pushed me over the edge was a recent change that added two particularly annoying pop-ups to my online experience (I must have agreed to something on a site that created ... or allowed ... them).  With one of them, when I hit a link on almost any page a new advertising tab opens and takes me to it ... I have to go back to the tab with the page that the link was intended to take me to (the link works, but the ad tab is added).  The other one is a pop-out that pops in from the right of my screen over whatever I'm looking at.  I can close it, but it's really annoying.

What would you suggests to fix this?

Thanks,

Phil
