Количество пораженных яваскриптов очень большое и чистить в ручную - нереал.

Подскажите утилиту или сервис, как вычистить код на стороне сервера, не прибегая к процедуре "слил - вычистил - залил"...

И еще вопрос - как эта дрянь попадает на сайт? Перед Новым Годом ломанули порядка 8 сайтов с дефейсом и редиректами. Все их перенес на другой хост. Остался один большой проект, который находится на том же хосте, что и взломанные, но на другой ветке (на другом тарифе). Сейчас все-таки грешу на хостинг.

Заранее благодарю!
