Translations:Complete Virtual Mail Server/amavisd spamassassin clamav/44/en

ClamAV is the de facto open source virus scanner for linux. Amavis can be linked to many different free and commercial virus scanners, but here clamav will be used. ClamAV is specifically designed for scanning e-mail. It consists of two parts, clamav itself, and freshclam, the clamav updating service. By default it updates every two hours, which should be enough for anyone.
