Can't create new folder

As of a few hours ago, I can no longer create new folders on my computer. It's a custom built computer and everything was running fine, norton found no harmful files when I ran a full scan, and I haven't downloaded anything fishy (all I've dl'ed were a few steam games, winrar, and some programs.) The problem started in the middle of the norton scan and a steam download.


This is pretty annoying, anyone have any idea how to fix this?

Norton is awfull.

Try doing this and taking ownership of whatever folder you are trying to make a new folder in.
