Updating Integrated Avast Antivirus

  • Last updated on

On November 11th 2020, Barracuda RMM made available a new Avast Business Agent (v 4.23) and Avast Antivirus (v 20.7). These releases addressed several bug fixes and introduced enhancement improvements. It is recommended that partners are aware of how their environment handle updates for the Agent and AV client as well as prepare for the eventuality of a required reboot for all devices with Avast Antivirus installed. 

Understanding Update Settings

  • Start with checking how your policy controls your updates.
  • Go to Configuration .
  •  Click on Policies.
  • Select Avast Antivirus.
  • Click on your Avast Antivirus Policy for the Site/Devices to update.
  • Go into Workstation (or Server) Settings.
  • Select General Settings.
  • Reference the below screenshot.


Automatic Updates are controlled by Avast and will occur within the Avast timeframe (usually overnight, sometimes it is simply as available). Manual Updates are controlled by Barracuda RMM and are informed by the Execution Schedule.

Using Manual Updates through the Execution Schedule

  •  Click on Configuration.

  • Select Schedules.
  • Choose Execution.
  • Click on the schedule for Site/Devices.

  • Click on Update Center
  • Select Products
  • Select sites
  • Click on Update
