Antimalware Agent Updates

After being installed on a Windows managed device, the Antimalware Agent auto-updates when a new agent version is released to the cloud service (i.e., the same repository from which signature updates are pulled). This document lists the released Antimalware Agent versions and fixes.

1.0 How to Know What Version is Installed

In ZENworks Control Center, you can use the Device Malware Signature Version dashlet located on the Security Dashboard to view the Antimalware Agent version installed on each managed device.

By default, managed devices check for Antimalware Agent updates every 4 hours. If an update is available, it is installed immediately. You can customize how often the check occurs by using the Antimalware Agent Schedules configuration settings at the zone, device folder, or device level. ZENworks Control Center navigation for these schedules is shown below:

  • Zone: Configuration > Management Zone Settings > Security

  • Device folder: Folder object (Details link) > Settings > Security

  • Device: Device object > Settings > Security

Typically, updates do not require a reboot, but the schedule lets you postpone potential reboots if desired. For more information about configuring the schedules, see Antimalware Agent Schedules in the ZENworks Endpoint Security Antimalware Reference.

To force managed devices to check for and install updates, use the “Update Antimalware Agent” action in the Device Malware Signature Version dashlet.
