Just go to that application and long press the icon for that. It will show you one warning that will tell you “’Mobile Security’ and associated content will be removed from your phone. Continue?” Click on yes as you want to remove that from your phone. As you click on “Yes” button then that will show you the progress bar for removing the application and it will be removed in seconds.
