Ask a hundred citizens what they think of Clam AntiVirus. One citizen will be a Linux manager. The remaining ninety-nine will think you're covering the latest recipe on the Food Network.

The Linux administrator will tell you Clam AntiVirus is the definitive open source anti-virus toolkit. She'll add that it's an easy build on any POSIX-compatible system with a C compiler, and meshes perfectly with any number of POP3, Samba and Web servers, as well as all respectable Message Transfer Agents, from sendmail to qmail to postfix.
