pop up blocker advice

I think I only have Webroot Internet Security. I know it's not complete and probably not plus. Anyways I was having trouble with these pop ups. Amazon the worse. Very annoying, thats when I had to call someone to help me get my computer back to normal. When all was done I asked if this version had a pop up blocker. I was told no it did not. I was than told that is why I would enable blocker on chrome an IE. Well I knew that. But like I said before I was a Norton user and I also had it enable  on Norton.
My question is how does anyone feel about having Webroot blocker for ads on computer? Is it worth it, or are people just relying on chrome and IE to do their job?
