System Updates

After an official product release, Trend Micro may release system updates to address issues, enhance product performance, or add new features.

System Update Types

Trend Micro may release the following types of system updates:

System updates

System Update	Description
Hot fix	A hot fix is a workaround or solution to a single customer-reported issue. Hot fixes are issue-specific, and therefore are not released to all customers. For non-Windows hot fixes, applying a hot fix typically requires stopping program daemons, copying the hot fix file to overwrite its counterpart in your installation, and restarting the daemons.
Security patch	A security patch focuses on security issues suitable for deployment to all customers. Non-Windows patches commonly have a setup script.
Patch	A patch is a group of hot fixes and security patches that solve multiple program issues. Trend Micro makes patches available on a regular basis. Non-Windows patches commonly have a setup script.
Service pack	A service pack is a consolidation of hot fixes, patches, and feature enhancements significant enough to be a product upgrade. Non-Windows service packs include a Setup program and Setup script.

Your vendor or support provider may contact you when these items become available. Check the Trend Micro website for information on new hot fix, patch, and service pack releases:

System Update Rollback

Threat Discovery Appliance has a rollback function that allows you to undo a system update and revert the product to its pre-update state. Use this function if you encounter problems with the product after a particular system update is applied.

Only the latest system update can be rolled back. After a rollback, none of the other existing system updates can be rolled back. The rollback function will only become available again when a new system update is applied.

Before performing a system update:

Save the system update file to any folder on a computer.

Save the system update file using its original name to avoid problems applying it.

All releases include a readme file that contains installation, deployment, and configuration information. Read the readme file carefully before applying the system update.

The readme file should indicate if a system update requires Threat Discovery Appliance to restart. If a restart is required, ensure that all tasks on the console have been completed before applying the update.

On the computer where you saved the file, access and then log on to the web console.

To apply system updates:

Administration > System Update

Click Browse and then locate the system update file.

Click Upload.

To avoid problems uploading the file, do not close the browser or navigate to other screens.

If the upload was successful, check the Uploaded System Update Details section.

This section indicates the build number for the system update that you just uploaded and if a restart is required.

If a restart is required, finish all tasks on the console before proceeding. You will be redirected to the web console’s logon screen after the update is applied.

Click Continue to apply the system update.

To avoid problems applying the system update, do not close the browser or navigate to other screens.
If there are problems applying the system update, details will be available in the System Update screen, or in the Summary screen if a restart is required.

Skip this step if a restart is not required.

If a restart is required:

Log on to the web console.
Check the Summary screen for any problems encountered while applying the system update.
Navigate back to the System Update screen.

Verify that the system update displays in the System Update Details section as the latest update.

The system update also appears as the first entry under the System update history table. This table lists all the system updates that you have applied or rolled back. A link to the readme file is conveniently provided in the last column of the table.

If you encounter a problem with the product after applying the update:

Check the readme for the system update for any rollback instructions or notes. For example, if a rollback requires a restart, ensure that all tasks on the console have been completed before rollback because the rollback process automatically restarts Threat Discovery Appliance.
Click Roll Back.
Check the rollback result in the first row of the System update history table. A rollback does not remove the readme file, so you can refer to it at any time for details about the system update.
