Avast Business Antivirus Release Notes 2025

 

Avast Business Antivirus releases run approximately two weeks behind the consumer release of new Antivirus versions, in order to allow further testing. CloudCare does not follow the same cycle. For this console specifically, Antivirus is released quarterly. The releases are made to Avast and AVG brands at the same time, including managed and unmanaged versions. In some cases, a version can be skipped (e.g. due to a defect in a particular version).

Microupdates do not have any specific schedule and are released as and when required to release a fix to a previous version immediately, rather than waiting for a full release (see Microupdates FAQ for more information).

The macOS Antivirus does not have such frequent releases as the Windows Antivirus (every Q is a loose timeframe). CloudCare does follow the same release cycle as the Hub for the macOS Business Agent, they cannot be released separately.

This article provides information on the Business Antivirus 2025 releases and is updated throughout the year.
