ClamTK menu not working

Use all lower case. Linux is very case sensitive. You can't add capitals just because you feel like it

Thank you clamtk open with the menu, but its the some as opening from the Unity click on icons nothing works.

Is there any output in the terminal when you run the command?

The only output is the clamtk a window opens with the title Virus Scanner with various icons on it and they
don’t work when click on it.

Does a command line scan run OK. If you run:

sudo freshclam

sudo clamscan --exclude-dir=/dev/* --exclude-dir=/sys/* --exclude-dir=/proc/* -i -r /

Does it run? Obviously if you have a lot of files or are not using an SSD this will take longer.

Are you running an email server or a file server with Windows clients?
