A system utilizes a browser toolbar or browser helper object to implement functionality that blocks unwanted advertisement and informational windows while a user is browsing a network. The system is initiated to receive specified events from a network browser. As the events are received, the events are analyzed to determine whether the window corresponding to the event is an unwanted advertisement or informational window. When the window corresponding to the event is an unwanted advertisement or informational window, the window is blocked by the system from being loaded or displayed.
