I figure myself to be pretty computer savy but I've come across and issue I have no idea how to fix. This wasn't something I did but something my girlfriend did it. Basically she downloads zip folders with Music in them. She figured it'd be a bright idea to click "Open with" and select iTunes...

Basically now every Zip folder she downloads is an itunes folder...which doesn't work. Everytime I go to change it the only option it gives me for recommended programs is iTunes. I am quite puzzled, and I don't want a quick fix like WinRAR or WinZIP. I want it to be restored.
