Hi Lord_Ami :slight_smile:

No problems with automatic updates in the Beta here.
Virus update history :

https://www.avast.com/virus-update-history

An update interval of 180 minutes can’t be the problem, as you can set it as low as 20 minutes.
Lower update interval settings will be ignored, and executed as 20 minutes intervals afaik.

Have you tried a repair of Avast ?
