Kotters PopDown is a free utility that helps to eliminate those annoying popup windows and banner ads you’ll no doubt encounter while surfing the web.

It runs, conveniently, in the Windows system tray and keeps a running count of the number of popups it has eliminated. It can be easily toggled on and off by double-clicking its icon in the system tray.

When PopDown finds a popup window, a few things may happen. First and foremost, the popup window will be immediately closed. Also, the tray icon will flash once, letting you know that PopDown was responsible for closing the window.

Optionally, PopDown may play a short sound and/or add the popup to a log file (see below).
