PopUp Killer is a small program which can be configured to automatically close previously selected Windows... cool uh? Well... this is basically the idea of the program, but since the first public version, No Popup has evolved from a purely manual application, where you had to manually select the PopUps to an intelligent program that can detect potential PopUp windows and close them so fast that you will not even have the time to see them!and Cachesize before you can optimize your modem settings, unlike other MTU tweaking utilities. Just click a button and Modem Booster will run the diagnostics and tune-up automatically. After tuning-up, anyone can speed up their surfing by clicking on Modem Booster's one click dialer before they go online.
