Pop-Up Zapper is a shareware application for Mac that helps you by "zapping" away those annoying pop-up windows when you surf the web.
Pop-Up Zapper watches the work of your web browser (IE) and when it identifies a pop up window (or pop-under) it makes it invisible to you and then closes it. Occasionally you may see a window flash really fast before it is zapped. You can look at Pop-Up Zapper's counter on its Dock icon to see that it is working. Pop-Up Zapper 2.0 makes popup windows invisible to you and it requires Internet Explorer. Pop-Up Zapper Lite for Mac OS 9 can work with Netscape 7 and Mozilla besides Internet Explorer 5.x
