Child Proof protects your computer from children accidentally pressing wrong buttons or keys. It hides all windows and the desktop and replaces all toolbars with the childproof toolbar that only has programs you allow your child to execute. When in child mode it is virtually impossible for the child to hit a combination of ctrl+shift+alt+p which turns the child mode off. (You can change this combination). This avoids most problems and minimum supervision when children use the computer.
