Sometimes applications can install extras in the form of System Preference panes. However, when you remove the app from your Mac, you might be left with extraneous System Preference panes.
To uninstall System Preference panes, just right-click (or control + click if you have a one button mouse) on the preference pane icon and select "remove x preference pane."
When you click "remove," the preference pane will be instantly moved to the OS X Trash can where you can completely remove it from your system by emptying the trash. Please note that this will only work on System Preference panes located in the "Other" section of System Preferences.
