Apple - How can I deinstall Drive Genius?

From the Drive Genius 3 User Guide:

To completely remove Drive Genius 3 and its utilities from your hard disk, click on Uninstall from the Drive Genius 3 menu. A prompt will appear to confirm you want to uninstall the application and will require administrator authentication to complete the process:

• Uninstall: Drive Genius 3 will remove only its support files from the operating system, but will leave the application and registration in its folders for future references.
• Uninstall All: Drive Genius 3 will remove all its files, including the support files, registration files and move the application to the trash can.

In case you've already deleted parts of the installation, you may need to re-download/install the Demo version first (direct download link).

In order to properly uninstall the demo of Drive Genius 3, you will need to manually uninstall it.

To manually uninstall Drive Genius 3 delete the following files and folders at the end of the paths listed below. Double click on your "Mac HD" drive to start the path.

/Library/Application Support/DriveGenius (folder)
/Applications/Drive Genius 3.app (icon)

If you are running OS X Lion, Mountain Lion, or Mavericks the last three files/folders are located in the user's Library folder which is hidden by the operating system. You can temporarily access this folder by opening a Finder window and pressing Command+Shift+G. This will bring up "Go to the folder", enter ~/Library and click go.

/Users/Library/Application Support/DriveGenius (folder) /Users/Library/Preferences/com.prosofteng.DriveGenius2.plist (file)
/Users/Library/Preferences/com.prosofteng.DGAgent.plist (file)

Now you will need to restart your computer.
