So long...POW!

AnalogX POW! A nifty little popup destroyer for IE.  It has slammed 14183 popups to date on my machine.

 
But it has been running in the system tray for a few years now since I no longer use IE. Opera does a very nice job in blocking ads.

I guess it is no longer needed...it definitely served it's purpose
