Delete additional thing in AdminCp

[skariko]

Hello,
i've uninstalled some plugins but it still remains in the ADMINCP on the left column like this that i've circled in red on the attach image.

How can i delete it?

You have not deleted the ./includes/xml/cpnav_XXXXX.xml that you have uploaded when you installed the modification.
