How to Stop Pop-Unders

by Kefa Olang

Pop-unders are basically annoying pop-up advertisements that show up behind your web browser without being overly intrusive every time you visit certain sites. They are distributed by the actual website you visit or can be from third-party websites. They advertise everything from shopping sprees to music downloads. Web browsers offer free features to block pop-unders/pop-ups while browsing the Internet. These easy-to-use features turn on in seconds and remove advertisements for a smoother web-browsing experience.
