Hi, that program isn't a good one. it's a spyware, it contains a code that makes possible to easily utilize your pc and see and copy the content of the host computer. you should remove it and suggest you to buy a reliable internet security software. kaspersky internet security 2009 is the best today or g-data's int. sec. software. both programs are all-in-one gadgets and could be purchased by Paypal.
www.kaspersky.com
www.g-data.de

for removal just uninstall it and then go to start - run and type "regedit" click ok and type "antivir" in find pane and delete all the entries and folders in which that name appears, then reboot your pc.

it's not worth to use those freeware programs as the danger is bigger that anybody would think. if you buy kaspersky, from the second year you will get 30% discount. if you will use internet security software, you don't need the microsoft firewall anymore on.
