Hey,
I have a question on something I saw on my computer today. I'm on a Windows Vista. I was looking at some of the "properties" of some folders in my "Public" folder and clicked on the "Security" tab. Then I noticed my usual login user, "Everyone", and one other user, whose id seemed to be S-1-5-21...and some numbers. Then after a couple moments it turned into the user, "None" with (My computer name\None) right next to it. I looked at the permissions it was given and apparently it was given "Special Permissions." I was pretty sure I didn't and never had created a user named "None". But I still checked the Users folder to see if there was indeed a user named "None". There wasn't. I even checked to see if there were any hidden users using the "view hidden folder option", but there was no uesr by the name of "None". I looked on google for some time but all I managed to find was that it could possibly be a remnant from a past OS or something. But this computer had Vista installed on it when I got it. Also, it might be some sort of guest that was made for my computer or something. My own speculation is that it has something to do with the fact that I used Cygwin to open up a tarball and create this folder. Anyway, what does this user mean? Why does it have special permissions? Is it some sort of sign that I have a back door somewhere on my computer or that I'm being keylogged or something? Thanks in advance.
