ClamAV Missing Decoder

carlosinfl · 03-26-2011, 10:10 PM

I have a Debian mail server running Postfix, Amavisd-new, Clamav, & Spamassassin. I noticed when I started all the daemons, the mail.log file had some missing decoders which I assume Clamav can't scrub.

This is what I see:

Code:

Was there a missing package for resolving what's causing this notifications in the logs?

Do you have the missing files installed, like
cabextract, unrar, arj,unarj, rpm2cpio etc..

Kind regards

I'm assuming not. Do I need to to install each package individually? I would think that they would be dependencies of a larger package.

Yes, use apt-get

Kind regards
