Still never heard of it. By any chance might it be a program called "JamVOX Executer"?
If it is you might find the following file installed on your Mac:
/Library/Application Support/VOX/JamVOX/JamVOX Executer.app
To determine if that's the culprit, select the entire line above (triple-click to select the entire line) and then control-click (or two finger tap) the line. A contextual menu will appear. Select Services > Reveal in Finder.
Describe what happens when you do that. If nothing happens, it's not what I'm thinking of.
