Use  the Web to research pop-up blockers. There are several good blockers available for free. Some work completely in the background, while others are part of a  toolbar that can be added to your Web browser. While these programs cannot block  all adware advertisements, they can do a good job of managing most pop-up  windows, which are an annoying part of Web browsing. Compare the features and  prices of these programs and determine which one you would choose for your home
system. Compare at least 3 adware you know.
