Despite the limiting name, Pop-Up Sentry swats away all kinds of annoyances. It handles pop-ups, banners, and Flash and DHTML ads without a hitch and didn't hinder our browsing at all. It lets through pop-ups for entering passwords via secure connections, as well as ones you've approved. Should an unauthorized pop-up slip by, you can report it to the developers with a click.
Though Pop-Up Sentry is not primarily an adware blocker, it does a better job than many specialized utilities. At 16MB, the program does consume a considerable amount of memory when running in the background. However, when supplemented with a free spyware scanner, Pop-Up Sentry provides a formidable line of defense for your PC.
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.
