#   0) No, i did not developed this for myself/my server. ;-)
#   1) I strongly recommend you to reinstall all your server software,
#   inclusive the whole operating system like linux, unix, etc. If you
#   use a web hosting service, backup your data and request your
#   provider for a fresh system. If this is not possible feel free to
#   try this script.
#   2) But before fixing your php files it's absolutely recommended to
#   change all your server passwords, update your software and re-check
#   all security settings!
#   3) After that, use this small script to recognize infected php files
#   and remove all „illegal“ parts of them!
#   4) Notice that this script may, but this is an incredibly case,
#   damage correct parts of your php files.
