I’m giving AntiPopup a try-out, and I have to say that I like it so far. It’s a little system tray applet that monitors your web browsing, and automatically closes the annoying pop-up (and pop-under) ad windows that have become the bane of any websurfer’s existence. The program’s caught the three that have attempted to launch in the last 15 minutes of my surfing; it it keeps working this well, it’ll earn a spot in my Startup folder.
