Stop-the-Pop-Up Lite is a free pop-up blocker preventing all annoying pop-up windows from appearing as you surf the Web. The pop-up stopper has full support for both pop-up and pop-under ads and will kill them even before they appear on the screen. Each time a pop-up is closed you will hear a cute sound effect. To allow pop-up windows, you can temporarily disable the pop-up killer by holding Control, Shift, or 'a'. Another Stop-the-Pop-Up Lite feature is its ability to kill all pop-ups from file-sharing programs as well as from the spyware and adware that is bundled with these peer-to-peer programs. Stop-the-Pop-Up Lite supports Kazaa, Kazaa Lite, Morpheus, Grokster, iMesh, Xolox, and Direct Connect.

Stop-the-Pop-Up Lite also will kill the new breed of pop-ups called Messenger Service spam. Messenger Service pop-ups can spam you even when your browser is closed. Stop-the-Pop-Up Lite recognizes and kills hostile ActiveX controls from companies known to develop spyware or adware.
Editor's review of Stop-the-Pop-Up Lite This program blocks annoying pop-up windows with a splash. Stop-the-Pop-Up Lite installs so quickly that you won't even notice it happening. Once you launch the freeware, you face a tiny number of choices. All you can do is disable the freeware, set it to launch automatically at Windows start-up, and enable the aggressive mode. The button marked Advanced Settings leads only to a nag screen that says that those features do not exist in the Lite version. In general, though, the program works well. When a pop-up emerges, the program immediately destroys it. The program excels even at counteracting file-sharing networks such as Kazaa and Morpheus. Home users could do much worse than the serviceable Stop-the-Pop-Up Lite.
