ZapPop The Popup Killer is an Internet Explorer pop-up killer that prevents unwanted pop-up and pop-under windows as well as banner ads. There is no need to set up particular Web sites or keywords; ZapPop The Popup Killer works without any user intervention. It sits in the taskbar quietly until it detects a pop-up. It then intercepts the window, which never appears. You even have the option of hearing a pleasant "zap" sound each time the program goes to work for you. Each "zap" tells you that ZapPop has stopped one more annoying advertiser from interfering with your enjoyment of the Internet.
Editor's review of ZapPop The PopUp Killer Simple as can be, ZapPop The PopUp Killer does its job, but proves to be a drag. You can install it and go, since configuration is limited to adding it to the Windows start-up, and setting sounds. It's worth noting that you can use any sound on your system for the pop-up-killing accompaniment; just point to any WAV file. In terms of functionality, ZapPop makes quick work of destroying pop-up windows before they open. Unfortunately, it slows down Internet Explorer significantly, a major drawback. With so many freeware programs offering the same or more functionality without any impact on surfing speed, we wouldn't recommend ZapPop as a leader in this crowded sphere.
