Antivirus
Note
SG565, SG580 and SG710 only.
The CyberGuard SG appliance’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.
The CyberGuard SG appliance 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.
Enable antivirus
Select Antivirus from the Firewall section of the main menu.
Check Enable.
The Database mirror is the host from which the signature database is updated. Unless
there is a specific host from which you want the CyberGuard SG appliance to retrieve
signature updates, leave this at the default setting of database.clamav.net.
Select the frequency to Check for updates from the database mirror. The checks are
quick and shouldn't cause a noticeable decrease to performance unless an update is
necessary.
