Popup Nuker is integrated into your Microsoft Internet Explorer browser, so it automatically starts when you start up Internet Explorer. The function key F12 will add new popups to the nuke list via the Popup Nuker Configurator and F9 will switch the program on and off. If you don't use IE then you can also use the Popup Nuker Configurator as a popup nuker by itself for any browser. With Popup Nuker you will be able to browse the Web without seeing those annoying popup windows and advertisements that you're not interested in. With features such as the Smart! engine, Popup Nuker can identify possible popups and close them even before you can see them.
