This week all computers in on-premise console required restart, so I did so, but today they started to require restart again. We did not change settings, there is also no program or agent update. Because those restarts also include our servers, it is big problem for us to reboot server every two days.
From AVAST Support: “I understand that you had multiple devices asking for reboot - this is likely to be the most recent AV program update (e.g. 20.3), we also did release a fix for an issue with sleep mode yesterday, which requires a reboot to complete.”
