anti-virus utility for Unix - base package
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 command-line scanner in the clamav package, and a tool for automatic updating via the Internet in the clamav-freshclam package. The programs are based on libclamav, which can be used by other software. . This package mainly manages the clamav system account. It is not really useful without the clamav or clamav-daemon package.
