The MyPopupKiller utility displays the list of all opened windows of your Web browser, and closes unwanted popup and advertising windows. In addition, it can automatically hide the internal ads of Kazaa Media Desktop, Download Accelerator (DAP), and Opera browser.

The MyPopupKiller utility can operate in 3 different modes:

Manual Mode: In this mode, MyPopupKiller displays the list of opened windows, and allows you to easily select and close the unwanted popup windows. The popup and ad windows are automatically selected, so you can close all of them in a press of a button.
Automatic Mode: In this mode, MyPopupKiller automatically closes popup and advertising windows, according to what you select in the configuration screen. You can temporarily enable the popups simply by holding Alt (the default), Ctrl, or Shift key (according to the configuration screen)
Aggressive Mode: In this mode, MyPopupKiller automatically closes all new browser windows, even if they are not recognized as popup or ad. In this mode, you cannot open new browser windows, unless you hold the Alt key.

MyPopupKiller supports the following Web browsers:
Internet Explorer: version 5.x and 6.x
Netscape: version 6.x and 7.x.
Mozilla
MSN Explorer (version 7.x)
Opera (partly support): version 7.x (although it not really needed because Opera browser has build-in support against popups)
