Enabling/Disabling VStream Antivirus
Chapter 12: Using VStream Antivirus 249
If you are subscribed to the VStream Antivirus subscription service, VStream Antivirus
virus signatures are automatically updated, so that security is always up-to-date, and your
network is always protected.
Note: VStream Antivirus differs from the Email Antivirus subscription service (part of
the Email Filtering service) in the following ways:
• Email Antivirus is centralized, redirecting traffic through the Service
Center for scanning, while VStream Antivirus scans for viruses in the
ZoneAlarm gateway itself.
• Email Antivirus is specific to email, scanning incoming POP3 and
outgoing SMTP connections only, while VStream Antivirus supports
additional protocols, including incoming SMTP and outgoing POP3
connections.
You can use either antivirus solution or both in conjunction. For information on
Email Antivirus, see Email Filtering on page
282.
