Hitware Popup Killer Lite is an intelligent popup killer for Internet Explorer (5 and up), that runs in the system tray and quietly eliminates most pop-up and pop-under ads before they appear. You can choose to be notified via animated tray icon or a sound whenever a popup window is closed, maintain a WhiteList of allowed sites, and also disable popup blocking from the tray, if needed. The program is very simple, without additional bells and whistles, however it performed well and closed just about all common popup windows during our test (www.popuptest.com). If you want no-fuss and fully automatic popup blocking, give it a try. This version is a Lite, because the author also offers a Pro version which offers additional features, besides the popup blocking.

Smart Popup Blocker is an easy to use popup blocker for Internet Explorer, that eliminates almost all popup ads while surfing the web. In addition, it can protect your browser home page from being changed, and can automatically delete unwanted cookies whenever you close Internet Explorer. It also offers an Allow List, to maintain a list of sites that you do not want to block, and the program is smart enough not to close popup windows that were triggered by clicking on a link.

PopOops is a small and simple program that blocks all popup windows in Internet Explorer. It runs in the system tray and optionally plays a sound and/or shows a balloon tooltip every time a popup is blocked. You can bypass the popup killer and open a link in a new window by holding down the Control or Shift key. PopOops does not allow any further customization or exclusions, but simply closes *all* popup windows.

Popup Manager is a small popup stopper add-on for IE that automatically disables all popup windows. It works a little different from most others, by adding a small color coded area to the bottom left corner of IE and displays a small icon for each popup closed. Clicking on them allows you to open the blocked popup and right clicking provides access to several options. Easy to use, effective blocking. Useful if you want to keep an eye on blocked windows, with quick access to re-open them if needed. Has a short delay with some popups, so you`ll see a tiny "flash" in some cases.

Pop This! is a small, effective, and intelligent anti-popup software product that works directly from within Internet Explorer, preventing popups before they are displayed and loaded. The program is easy to use and offers some configuration options from the IE tool menu, including an option to exclude certain domains and prevent sites from resizing your browser window. Simple, but very effective.                           Screenshot

Shoot The Messenger is a very simple tool that helps you get rid of annoying IP based Messenger popup ads (the ones that use the Windows NT/2000/XP Messenger service). These popups are unlike regular popups, since they abuse the Messenger Service, which is intended to send text messages across a network, using the computer`s IP address. They can appear as dialog box on your desktop if you have the Messenger Service enabled and are not using a firewall. Shoot The Messenger will display the current status of the Messenger Service and allows you to turn it off/on with a simple click, without having to go into the Windows configurations panel. The program does not need to be running after the service has been turned on or off. It can also be used from the commandline.                                 Screenshot
