freshclam WARNING: Current functionality level = 58, recommended = 60

Вот такую ошибку выдал clamav, когда я хотел обновить антивирусную базу:

В wiki я так ничего и не нашел как обновить clamav, решил это вот таким путем, раскомментировать строку в файле /etc/apt/sources.list

deb http://archive.ubuntu.com/ubuntu/ lucid-backports main restricted universe multiverse 
aptitude update

Обновляем пакет clamav до новой версии:

aptitude install clamav
freshclam

Получаем результат

Не забудьте закоментировать обратно строку в файле /etc/apt/sources.list
