Что делает этот скрипт? Зловред?

Доброго всем здравия!

Попросили посмотреть сайтик, сказали что вроде как яндекс на него ругается, типа пишет что опасен. Я глянул в потроха странички - и вижу какой-то непонятный мне ява-скрипт. Скрипт вдобавок ко всему еще не отформатирован, что затрудняет его чтение, плюс там еще чего-то много закодировано, поэтому он у меня вызывает подозрения, но сам я в скриптах не силен и прошу вас посмотреть, что делает нижеприведенный код скрипта.

Спасибо!
