[ClamAV | http://www.clamav.net/] is a [Free] ([GPL]) [Virus] scanner for [Linux], [Solaris], [*BSD], [AIX], [MacOSX], [Cygwin] B20 on multiple architectures such as [Intel], [Alpha], [SPARC], Cobalt MIPS boxes, [PowerPC] and [RISC] 6000. It started as a [C]-based reimplementation of of the abandoned [Java] !OpenAntiVirus. Signature updates are available in an open FileFormat.
[ClamAV] comes with a tool called __freshclam__ which updates the virus database automatically: it downloads the database from !http://database.clamav.net/ (a round robin record that tries to equally balance the traffic between [all the database mirrors | http://www.clamav.net/mirrors.html]) which is split into two files called __main.cvd__ and __daily.cvd__. __daily.cvd__ is updated frequently and occasionally is merged with __main.cvd__.
-[ClamAV] can be used by [ContentScanner]s to scan [Email]s on many [MTA]s. The [ClamAV] package includes one written by Nigel Horne for SendMail called __clamav-milter__. Another one is [smtp-vilter | http://www.etc.msys.ch/software/smtp-vilter/]. They both use the SendMail "milter" [API]. You can also use [ClamAV] to scan all [POP3] traffic with __pop3vscan__. See ClamAvPopVscan. In fact you can even use [ClamAV] to scan your incoming mail in Outlook: just get [ClamWin | http://clamwin.sourceforge
.net] and install the Outlook Plugin!
+In issue 8/2004 (April 5, 2004), the German computer magazine [c't | http://www.heise.de/ct/] published a comparative review of a number of virus scanners, in which they reported that [ClamAV]'s signature updates are provided far too slowly to adequately cope with the contemporary appearance rate of new mail worms, of which new mutations sometimes follow each other within hours. On the other hand, a lot of people appear to have had experiences to the contrary. That articles also mentions that [ClamAV] lacks "code emulation", an easy way to identify variations of a PolyMorphicVirus.
+
+Anyway, you can see [ClamAV]'s response times by yourself at http://news.gmane.org/gmane.comp.security.virus.clamav.virusdb
+I suggest you check them out before you say [ClamAV] doesn't suit your needs. You could be surprised.
