Friday Freebie

Today we have just one Friday Freebie, but it's a good one.
CLAM AV is a GPL'd anti-virus package available on a plethora of operating systems - Linux (SuSE, Fedora Core, Slackware, etc..), Debian, FreeBSD, MacOS, Windows, and even BeOS.
CLAM AV offers the following features:

• command-line scanner
• fast, multi-threaded daemon
• milter interface for sendmail
• database updater with support for digital signatures
• virus scanner C library
• on-access scanning (Linux?? and FreeBSD)
• detection of over 40000 viruses, worms and rojans
• built-in support for RAR (2.0), Zip, Gzip, Bzip2, Tar,MS OLE2, MS Cabinet files, MS CHM (Compressed HTML), MS SZDD
• built-in support for mbox, Maildir and raw mail files
• built-in support for Portable Executable files compressed with UPX, FSG, and Petite

The CLAM site lists a ton of hosting companies and universities that are using the GPL software for anti-virus scanning, but what it doesn't show is ISVs that are using the AV as a default option for scanning, like Forum Systems.

Forum is using CLAM AV as the default AV scanner for XML documents, and though I haven't tested CLAM on its own merits, I've been testing Forum Systems' latest XWall release in the lab and as part of that testing I've been pounding on its AV capabilities, which necessarily means that CLAM is being peripherally tested. Thus far, CLAM AV has stopped the viruses it should in the XML documents and attachments I've tried to send through the device, and hasn't impeded performance overly much.
Check it out. It offers automated update capabilities and the database appears to be updated daily. You'll never again get those "subscription expired" notices with this AV scanner, guaranteed.
