Strange "Hello World" menu item on right click

Question

Hello - for a few days now I am getting a strange Hello World contextual menu item when right clicking in some applications… Excel, iPhoto… It's at the bottom of the items separated by a line. When I choose it a text clipping kind of window comes up with German heading "Ohne Titel". In it it shows Hello World, which cannot be edited. Closing window is the only option.
Any idea what this is and how to remove it?

Answer 1

It displays which ever application is active, i.e. the window seems to belong to that application.
Below is a list of "My Processes"… I am not familiar enough with the list to say if there is anything unusual in it.
