You don't really have to be a "Unix guy" to run the command from the globaldelight.
http://www.globaldelight.com/boom/download/installers/mavericks/uninstall-boom-device.html
Double-click the downloaded command.
Your Script Editor will open, showing the commands that will run.
Click the Run icon.
It will ask for you admin password.
The script runs.
And, that's it. It should fix you up.
Also, it's pretty simple to find the relevant files (if you still have problems)
You would look for any files that have "globaldelight" or "boom", or "Boom2"
Delete all such files, restart your Mac, and all should be good.
And, as a final touch, you can boot to your Recovery system, and reinstall the system. Any accidental changes to the "real" system files would be repaired/replaced with the good files from the installer. It won't affect your own files, or other apps that you might have added to your system.
