About Updating Components

Updating means downloading antivirus and anti-spam components from the update source to InterScan™ Messaging Security Appliance (IMSA). To automate the update process, configure the update schedule.

Components

To help protect your network, IMSA uses the following components:

To verify if IMSA has the latest components, perform a manual update. For instructions, see Updating Manually.

Update Methods

You can configure an update schedule or download components manually. Configuring the update schedule, which is enabled by default, relieves you of the task of keeping IMSA up-to-date. However, if you think that a virus or Internet threat has infected computers in the network, you can immediately update your components manually.

Trend Micro can update components several times daily. For a reliable level of protection, configure the update schedule to download components hourly (the default selection.)

 

Proxy Server

If there is a proxy server between IMSA and the Internet, you must configure proxy server settings or IMSA will not be able to connect to the update source.

Update Sources

By default, IMSA downloads components from the Trend Micro ActiveUpdate server, which is the only source for up-to-date components. However, if you are using Trend Micro Control Manager (TMCM) to manage IMSA, you can update the components from the TMCM server. See your TMCM documentation for details on how a TMCM server can act as an update source.
