Well I'm a moron.
I've been learning a bit about AI and thinking of doing some programming in that area, and I was looking around and found a downloadable tutorial (or so I thought). I downloaded the file, and my virus scanner caught something. So I went to delete the file, but everytime I do, I get the message:
Cannot delete tutorial: Access is denied.
Make sure the disk is not full or write-protected and that the file is not currently in use.
How the heck do I delete this?
