From ACP run the Suspect File check (ACP->Maintenance->Diagnostics->Suspect File Versions)

I checked. Writes:
forum.php the File isn't part of vBulletin
index.php the File doesn't contain the expected contents

Проверил. Пишет:
forum.php Файл не является частью vBulletin
index.php Файл не содержит ожидаемого содержимого

It occurred in itself. The site normally worked the last months and I didn't do any changes at a forum and on a hosting.

Это произошло само по себе. Сайт нормально работал последние месяцы и я никаких изменений не делал на форуме и на хостинге.
