Secure Computing SG300 User Manual page 189

The SnapGear unit's antivirus capabilities shield your LAN from viruses that propagate
through email, the web and FTP. An antivirus subscription is not required and virus
definitions are automatically kept up-to-date.
Note
If you are seeing messages in your system log stating your clamav is OUTDATED, it may
be possible to update the SG's virus scanning engine (ClamAV) by upgrading your
SnapGear unit's firmware. Typically, such messages are not cause for alarm and
Antivirus will still be functioning correctly. Contact your reseller for details on how to
obtain new SG firmware.
As with all firmware updates, Secure Computing will determine an appropriate firmware
release schedule based on the nature of the changes made. Serious vulnerabilities are
given priority over feature enhancements.
The SnapGear unit is equipped with proxies for POP, SMTP, HTTP and FTP that
facilitate the transparent scanning of files passing through it. If a virus is detected, the
user on your LAN sending or receiving the infected file or email is informed by an error
message or error email, and the infected file or email is not delivered to its destination.
This message will be similar to the following:
E-Mail was blocked by pop3.proxy/2.0.0-beta5 using ClamAV
