Pop Up Blocker has four types of pop-up blocking: 100 percent pop-up blocking, a block list, a block list with Mots-clé, and a limit on the number of open windows. Pop up Blocker also blocks Flash Ads, Background sounds, Inline videos, JAVA Applets and Animated gif files. This program is packed with advanced privacy-protection technologies, which prevent your home page from being reset, protect your proxy settings, provide a sound effect upon closing pop-ups, disable auto suggesting, and block messenger-spam pop-up ads.
