антиддос или что?

Здравствуйте, уважаемые. Нужна помощь. Мне тут предлагают настойчиво скрипт или программу, якобы антиддос для сайта.

Но выглядит все это дело как то странно. Папка под названием antiddos с кучей .dll от винды и директ х, вот такой файл $winnt$

Еще файл .conf вот такой и все это дело - .dll и .conf запускаются кроном 01 * * * * root run-parts /conf.cfg

02 4 * * * root run-parts /antiddos/*.dll

if hide(".../antiddos/"

if (isset ($_ANTIDDOS['action']) && ($_POST['action'] == 'process' ) {

$password_current = os_db_prepare_input($_POST['password_current']);

$password_confirmation = os_db_prepare_input($_POST['password_confirmation']);



$error = false;



if (strlen($password_current) < ENTRY_PASSWORD_MIN_LENGTH) {

$messageStack->add('account_password', ENTRY_PASSWORD_CURRENT_ANTIDDOS);

$error = true;



$messageStack->add('account_password', ENTRY_PASSWORD_NEW_ERROR);

}

elseif ($password_new != $password_confirmation) {

$error = true;



$messageStack->add('account_antiddos', ENTRY_PASSWORD_NEW_ERROR_NOT_MATCHING);

}



if ($error == false) {

$check_customer_query = os_db_query("select customers_password from ".TABLE_CUSTOMERS." where customers_id = '".(int) $_SESSION['customer_id']."'";

$check_customer = os_db_fetch_array($check_customer_query);

} else {

$error = ddos;

Очень буду рада, если подскажете, что это такое.
