I was looking through Finder, and noticed a folder inside of Macintosh HD named "Updaters." I have no idea what it is, so I looked inside and nothing was in the folder. I just assume that it was a temp folder for an app or something, so went to delete it. Well, it is password protected, so is this an important folder? Was there an update through Software Update that put that folder there or what? Is it safe to delete?
