I don't even know when I installed TuneUp. It's a bad app, so I decided to delete it. But there's still one app/alias file left which I can't delete it. When I try to open it, a window pop up says "The alias "TuneUp" can't be opened because the original item can't be found". And the info of the file show the file size is 0 kb. Wired! Doesn't anyone have the same experience and know how to get rid of that 0 kb file? Is there a Mac version "Hijackthis" application that can let you delete whatever I want?
