Updates to the Antimalware Agent are released periodically and the check for updates is built into the zone update schedule, which can be configured for a fixed interval or specific days and times during the week. There are also override options for this schedule at the device folder and device level. The default setting uses the fixed interval and checks for changes to the Antimalware Agent every 4 hours. When an update to the agent is detected, it is downloaded from the Antimalware Cloud Service through content servers and installed on the device. If a reboot is required, there are postpone reboot and enforce reboot settings that you can modify in the same schedule.
For information about modifying current settings in the update schedule, see Antimalware Agent Schedules.
If you have indication of an Antimalware Agent update failing to install, there could be one of several different causes, including a communication issue between the OCM and the CDN, inadequate disk space on the OCM or other content servers, an error downloading content, and so forth. To troubleshoot for a potential Antimalware issue, look for a cause in the ondemand-content-servlet log in the upstream OCM that communicates with the CDN. To troubleshoot for a potential issue with the update bundle, see Troubleshooting
in the ZENworks Software Distribution Reference.
NOTE:Antimalware Agent updates can be similar in size to the original installation and the same recommendations for disk space, RAM, and scheduled distribution apply to updates. For more information, see Agent Installation Requirements.
