Q: Guest user off but still "OTHER" shows up at restart

Using MacBook Air and have Yosemite installed. When I restart this MBA, it shows my login and "OTHER". I don't want OTHER showing there.

I go into System Preferences and "Users and Groups" and have GUEST USER set to OFF, and boxes to right unchecked which show: "Allow guests to log in to this computer" and "Allow guest users to connect to shared folders". I also have "Automatic login" set to OFF, and "Display login windows as - LIST OF USERS".

So when I have it all OFF does it continue to show that OTHER icon for logging in. When I choose it, there is a box for UserName and Password, which makes me think someone hacked into my computer, and has this sitting there, so they can login and use this. Is there a way to remove that OTHER login from showing up when I restart this MBA?
