    Hello,

    File and folder permissions for several accounts are constantly changing. They become 777 and cause Internal Server Error. I fix them but they'll change again tomorrow. There are some files appear in public_html. They named like mail.bak.php php4.bak.php etc.. The share same content:

    Not Found

    The requested URL <?php echo $_SERVER[REQUEST_URI]; ?> was not found on this server.
    Apache Server at <?php echo $_SERVER[HTTP_HOST]; ?> Port 80.
    <?php
    if(!empty($_SERVER['HTTP_USER_AGENT'])) {
    if(preg_match('/CheckMe/i', $_SERVER['HTTP_USER_AGENT']) && function_exists('mail')) {
    echo "_i_am_" . "_alive_";
    }
    }
    ?>

    Do you have any idea what can it be? I checked access logs and file dates but couldn't found anything.

    Not enough info to help here I don't think. Sounds like compromised accounts to me.

    If you're unsure of the path forward you might want to consider hiring someone to assist you with this.
