The ThirdPersonController.js issue is just a warning, which you can ignore. The problem with your abc.js is that your PC associates JS files with Windows Script Host. This Microsoft application does not know how to process JavaScript files created with Unity. Change your file extension associates to associate .JS files with monodeveloper or perhaps notepad.
