Cisco Cisco Email Security Appliance C170 Guia Do Utilizador

For information about how and when anti-virus scanning is applied, see 

.

By default, the Cisco IronPort appliance is configured to check for updates every 5 minutes. For the 
Sophos and McAfee anti-virus engines, the server updates from a dynamic website. 

The system does not timeout on updates as long as the update is actively downloading to the appliance. 
If the update download pauses for too long, then the download times out.

The maximum amount of time that the system waits for an update to complete before timing out is a 
dynamic value that is defined as 1 minute less than the anti-virus update interval (defined on Security 
Services > Service Updates). This configuration value aids appliances on slower connections while 
downloading large updates that may take longer than 10 minutes to complete. 

Once you have accepted the license agreement and configured the global settings, you can use the 
Security Services > Sophos or McAfee Anti-Virus page (GUI) or the 

antivirusstatus

 command (CLI) 

to verify that you have the latest anti-virus engine and identity files installed, and to confirm when the 
last update was performed.

You can also manually perform updates. From the Security Services > Sophos or McAfee Anti-Virus 
page, click Update Now in the Current McAfee/Sophos Anti-Virus Files table. The appliance checks for 
and downloads the latest updates.

In the CLI, use the 

antivirusstatus

 command to check the status of your virus files and 

antivirusupdate

 command to manually check for updates:
