Pop-up Stopper

Pop Up Stopper prevents web pages from popping up or popping under your current browser window. Many sites have advertisements or other types of pop ups that are very annoying. When you try to close them, many others may pop up (or under where you can't see them). Pop up stopper puts an end to all that. I highly recommend this free program but it is not required if you have Windows XP Service Pack 2.
