Hello hthrdnbr, and welcome to Seven Forums.
I believe the Spybot issue is that you may have needed to right click on the Spybot shortcut, and click on Run as administrator
instead for it to be able to.
If you mean that you would like to disable the built-in "Administrator"
account, then as long as your user account is an administrator type, then you should be able to use the tutorial below to disable it. Built-in Administrator Account - Enable or Disable
Hope this helps,
