i have a home computer, so why do i have 2 local area connections? ive never had 2 until a few hours ago, when i reformated. ive always only had 1. i have already tried to disable the second on but it wont let me, and if i disable the first one, my internet goes down.

also, for some reason, when i uninstalled my vga drivers which were messing up, the second one disappeared.

anyone know why? did i get hacked in the time between reformatting and installing my virus scanner?
