 Clam AntiVirus is an anti-virus toolkit for Unix. The main purpose of this
 software is the integration with mail servers (attachment scanning). The
 package provides a flexible and scalable multi-threaded daemon in the
 clamav-daemon package, a commandline scanner in the clamav package, and a tool
 for automatic updating via Internet through the clamav-freshclam package. The
 programs are based on libclamav2, which you can use in your own software.

 This package contains the ClamAV milter for use with sendmail. It can
 be configured to be run either standalone, or using clamav-daemon.
