Yeah, it looks like someone who knew how to lock down the files left a bunch on my FTP directory. I've tried every trick in the book to delete the folders but to no avail. I suppose FDISK/FORMAT will take care of it but that's a huge pain.

I've lifted anonymous login privileges from my site. It's a sad state of things when you can't offer the Internet community a way to access files anonymously. You try to do something nice for people and you get hacked...
