Sorry to bother,ù
I am a newbie who has recently been hacked and so I leafed about joomla extensions and I found this plugin. Yet once installed and configured I have got the following problem:
Warning: main(/administrator/includes/admin.php) [function.main]: failed to open stream: No such file or directory in /web/htdocs/www.modshair.it/home/htdocs/administrato...tes/khepri/index.php on line 14

Fatal error: main() [function.require]: Failed opening required '/administrator/includes/admin.php' (include_path='.:/php/lib/php/') in /web/htdocs/www.mydomain.it/home/htdocs/administrato...tes/khepri/index.php on line 14
Warning: main(/administrator/includes/admin.php) [function.main]: failed to open stream: No such file or directory in /web/htdocs/www.mydomain.it/home/htdocs/administrato...tes/khepri/index.php on line 14

Fatal error: main() [function.require]: Failed opening required '/administrator/includes/admin.php' (include_path='.:/php/lib/php/') in /web/htdocs/www.modshair.it/home/htdocs/administrato...tes/khepri/index.php on line 14

I obviously realized that I had inserted the code in the wrong file, I erased it and I set it into the login one, but it's the latter now looking for /administrator/includes/admin.php.
I have no such thing in the includes folder, though. I only have application/defines/framework/helper/pagenaavigation/toolbar and router.php.
What did I do wrong?
Thanks in advance for your help and sorry if I am such a dummy
