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.
