Changing this prefix will prevent most exploits. If your site is already set up you can use a tool called “EasySQL” to change your current database prefix.Creating a new super administrator will also create a new user ID. Hackers already know 2/3rds of your original Super Admin information. They know the Username and User ID. They only need to figure out your Password.Turning off the editor site wide in the global configuration will prevent front end users from uploading and manipulating files from the front end. Just select NO EDITOR from the dropdown list.
