NagBlaster by Divad Software

Do you spend more time closing those nagging pop-up windows than you do browsing when you are surfing the net. Now you can eliminate them. When you see a nagging pop-up, just click the NagBlaster from your startbar and select the window to eliminate, and NagBlaster will close that window now and forevermore.

Future versions will work much like Napster. If several users all select the same pop-up, and it gets eliminated often, it will be added to a nag list and distributed to all NagBlaster users.
