KewlBar Free Pop Up Blocker is for Internet Explorer 5.0 or higher, AOL, Outlook Express, PalTalk, Kazaa, WeatherBug, Gain, Gator, iMesh, and all pesky adware. It includes Google, MSN, Yahoo, AOL, and AltaVista searches, as well as a built-in dictionary, thesaurus, and encyclopedia. A toggle switch facilitates blocking or allowing pop-ups, and the zoom-in/zoom-out feature is simple to install and use. Your feedback on this program is greatly appreciated.
