Configuring Virus Definitions and Antivirus Updates

This Article Applies to:

  • Essential/Premium/Ultimate Business Security
  • Small Office Protection


You can automatically update the virus definitions and Essential/Premium/Ultimate Business Security or Small Office Protection program version on your device(s) when new updates are available. You can also set your device(s) to update manually. For more information, see Updating Antivirus.

If you have a Windows device, Avast advises configuring Windows updates to run separately from Essential/Premium/Ultimate Business Security or Small Office Protection updates in the event conflicts occur while both updates are running concurrently.
