you need to identify, how the intruders got access to the files on the site - by default, they should be protected against write access, but a weak ftp password or missing security patches might have been abused to gain access to your server. Check the server event log for hints, what has happened.

Another tip for determining how the hack occurred. From the desktop of the server (ask your hosting company to do this if you don't have access), Open Explorer, right click the column view and choose "more", enable "owner" and view the owner of the file. if it's NOT your FTP user then the hack didn't occur via ftp credentials but from another hole.
