Hello,
I'm afraid that I don't understand your message or its purpose.
What is the point of removing an entry in the Joomla backend menu ?
Nicolas recommended you to update your Joomla due to the security patchs made in the past years (Joomla 3.1.0 has been release in 2013).
Nothing less, nothing more.
Regards,
