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, a command-line scanner, and a tool for automatic updating via Internet. The programs are based on a shared library distributed with the Clam AntiVirus package, which you can use in your own software.

Changes: ClamAV 0.103.2 is a security patch release that addresses privilege escalation, buffer over-read, and denial of service issues.
