Zmiana nazwy index.php w htaccess w codeigniter - codeigniter

Chcę zmienić nazwę index.php w pliku htaccess, którego użyłem do usunięcia długiego adresu URL, zmieniłem nazwę index.php na main.php, jest to spowodowane nadpisaniem mojego index.php przez hakera.

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
#Removes access to the system folder by users.
#Additionally this will allow you to create a System.php
#controller, previously this would not have been possible.
#"system" can be replaced if you have renamed your system folder.
RewriteCond %{REQUEST_URI} ^CI_System.*
RewriteRule ^(.*)$ /cacworldwide/main.php?/$1 [L]
#Checks to see if the user is attempting to access a valid file,
#such as an image or css document, if this isn"t true it sends
#the request to cacworldwide/main.php
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /cacworldwide/main.php?/$1 [L]

</IfModule>
<IfModule !mod_rewrite.c>
# If we don"t have mod_rewrite installed, all 404"s
# can be sent to main.php, and everything works as normal.

ErrorDocument 404 /cacworldwide/main.php
