Firewall

172

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 SG unit 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.

Enable Check for updates when networking starts to force a virus signature update

when the status of the network changes, e.g. when the Internet connection comes online.

This guarantees a virus signature update when the SG units boots.

Specify the Maximum size in kilobytes of files to scan for viruses. Files over this size are

automatically rejected.

You may Treat encrypted content as viruses – as the SG unit is not the intended

receipient, it does not decrypt encrypted content passing through it, and cannot

determine whether such content is infected.

Specify the Maximum number of simultaneous virus checks to perform. Permitting

more scans increases the amount of memory and CPU resources required by the

antivirus scanning.

Click Submit.
