I have removed the "guest user" account by: System Preferences → Users & groups → Guest User → Remove.
It still remains as an option under users (but states disabled).
It still shows up on login screen and if selected allows guest to logon to computer.
How do I remove guest login completely so that is is not even an option at login?
How to disable that “Guest User” from appearing at the OS X login screen
Open System Preferences
Go to “Users & Groups” and click the unlock icon
Click on “Guest User”
Uncheck the box for ‘Allow guests to log in to this computer’
The key here is everything must be disabled. Once you completely disable the account, it will no longer show up on the login screen.
If you have older versions of OS X, follow the instructions below:
sudo defaults write /Library/Preferences/com.apple.AppleFileServer guestAccess -bool NO
sudo defaults write /Library/Preferences/SystemConfiguration/com.apple.smb.server AllowGuestAccess -bool NO
I just tested this on 2 iMacs one from 2012 and one from 2009 both running Mac OS 10.13 and both have 2 login possibilities: the user's login button and an "Other" login button which asked for inputs for user name and password.
The true culprit here is whether “root user” is enabled or disabled. Here is how to check and disable root user if necessary:
When Root User is enabled your login screens will always present an “Other” login button. Root user should only be active under special circumstances. Keep it disabled as the norm.
I no longer have an OS 10.8 Mavericks system to test on, but I think from your description that you had a real user account named "Guest" and deleted it. That enables the special Guest account, the one that's automatically created on each login and destroyed on each logout.
To disable that one, go back to System Preferences → Users & Groups → Guest User (he's baaack...), and uncheck "Allow guests to log in to this computer".
Guest and haven't deleted it. In Terminal, the command id guest should return something that begins with id=201(Guest gid=201(_guest) groups=.... If you get a different id, one bigger than 500, then the Guest user you're seeing is a regular user. Also, if you're using FileVault, the list you see is the list of users who can decrypt the boot disk. That may include users who no longer exist. What happens if you log in as Guest? What do you see when Fast User Switching?

If disabling won’t work, then you can also delete the account. The account does not exist in a default installation, but is only created when it is first enabled in Users & Groups.
sudo dscl . -delete /Users/Guest
Use the below command on terminal:
sudo fdesetup remove -user Guest and tap Enter.
It will ask for the admin password. Enter that password and the Guest user login will be removed.
I have High Sierra and this worked for me.

Go to Logon Options.

Open Directory Utility.

Go to menu bar and open Edit dropdown.
Disable Root User.
Lock and close all windows.
Restart.
