Xavier's Popup Killer will kill all annoying pop-up windows before they appear on the screen. The popup stopper has full support for both pop-ups and pop-under ads, and each time a pop up is closed you will hear a cute sound effect. To allow pop-up windows you can temporarily disable the pop-up killer by holding Control, Shift or 'a'.

An unique Xavier's Popup Killer feature is that it will kill all pop ups and rotating banners ads from file sharing programs and the spyware/adware that are bundled with these peer-to-peer programs. Xavier's Popup Killer supports Kazaa, Morpheus, Grokster, iMesh and Direct Connect.

Xavier's Popup Killer will also kill the new breed of pop-ups called Messenger Service spam. Messenger Service pop ups can spam you even when your web browser is closed. Xavier's Popup Killer will also recognize and kill hostile activeX controls from companies known to develop spyware or adware. Gator, GAIN, C2, Comet Systems, Cydoor, Marketscore etc, are on the popup killer's black list. The banner ads in ICQ pro 2003 and MSN Messenger 4.6-5.0 are also removed.

Xavier's Pop-up Killer can be set-up to start automatically and can be used with the most popular web browsers, such as Internet Explorer, Netscape Navigator, Opera, MSN Explorer 7, Mozilla, SBC Yahoo! and NetCaptor. It doesn't require too much resources from your computer and no setup is needed! Pleasant surfing!

Xavier's Popup Killer is Windows 95/98/ME/NT/2000/XP compatible.
