Removing a Program

[Bart]

I did an install for a booster to pick internet from the house to an outbuilding by just hooking up the booster & it installed a program automatically which it has never done before now I always get 2 bar reception indication on my 2.2 lite system most of the time it tries to hook up with out the program with 2 bars indicated & when the window comes up asking if I want to use the program I say no & it hooks up 3-5 bars indicated reception there seems to be a clash between the 2 ways of hooking up here. On the other laptop I get 4-5 bar indication all the time without the program. Where do I have to look in the Lite 2.2 system to find this program & remove it?
