Browser cleaned window

How can I deactivate the window that comes up and tells me how many MB has been cleaned from my browser every time I close it?

Thanks

I've always had it turned off, so I'm guessing here, but it sounds like a Monitoring option.

Go into Options, Monitoring and uncheck both System monitoring and Active Monitoring.

Turn off all three monitoring protocols or, I believe there is a clean but do not inform option. I'm notat a computer right now, so I can't verify that last one.
