My grandmother wanted to get internet service this year so we got it for her. She is 84 years old. I got her Netzero for free and the problem is that there are so many pop ups that it confuses her. She winds up having to click out of at least 5-10 pop up every time she boots the computer to the net. I need to get something for her that will block all of these from happening. Please recommend a good pop up blocker for her and netzero.
