I am not too familiar with the full version of AVG, but if you right click on the icon at the bottom left you should get either a disable option or go into the main window and from there close it out.
I am pretty shure that there is some registry protection on it too, so be aware if it pops up to click allow to get it to work properly.
Yeah, dial up........is that like for real?? I mean it might be worth something when it is that old....
good luck
