Pop-Up Sentry Anti-Spyware blocks all types of advertising including pop-ups, pop-unders, Flash ads, rich media, fly-in and slide-in ads, spyware ads, and messenger ads. It blocks more than 100,000 major spyware and adware programs, Trojan horses, and home-page hijackers. Automatic updates keep the application current at all times, and the program completely cleans your cache, cookies, and browser history. Pop-Up Sentry also blocks sponsored search ads on Google, MSN, and Yahoo and optionally blocks annoying ad banners. The program is easy to use and contains no spyware, adware, or any other harmful software. Sponsored-ad and banner blocking is now available under the advanced options and is off by default.
Version 4.0.1008 has an updated anti-spyware scanner, supports IE7 and Firefox and introduces a new bandwidth saving mode for ad-blocking.
