Interesting, two things:
- presumably this feature isn’t available/compatible with XP as it isn’t in the Components > Performance section.
- it isn’t installed on my win10 avast free installation.
Maybe you didn’t install that component ??? It’s on my windows 10 and the Free version of Avast.
I can’t recall doing it and most of my recent program updates (on both my XP and win10 systems) have been manual program updates from the UI, not a clean install and custom settings.
If disabling Silent Mode (now Do Not Disturb mode) does not help, try to uninstall DND mode component.
You can do that via Settings => Components, or via Control Panel => Add/Remove Programs.
DND mode is indeed not compatible with XP and as such, cannot be installed there.
As for debugging this stealing focus problem, please also try killing the AvastUI.exe process before starting your game (without disabling DND mode). This needs to have self-defense disabled first in settings. Let us which of the two things helps and we can try reproducing it locally then.
Thanks, good to know.
Thanks for the confirmation, I though that may have been the case.
Not to stir the pot, but I don’t recall this (seemingly now common issue) being discovered/reported during our beta testing. Did I miss it?
Mind you having said that we are short on beta testers.
I’m back with news.
Unfortunatelly I don’t have much information to give. All I can say is that I disabled ‘Do Not Disturb Mode’ and started a game which created issues. The game didn’t alt+tab itself anymore.
Then I did the following:
- Closed the game, re-enabled Do Not Disturb Mode → Start the game → No issue (I found this strange)
- Restarted the computer → Start the game → No issue again
I’m not sure if only disabling / enabling this feature fixed my problem or just disappeared itself. I’ll keep watching anyway. If the problem will appear in future, I’ll try to test these configuration and come back. If I will not have anymore this issue, you won’t see any reply from me here 
After turning it off, did you hit the OK button on the bottom and then reboot the system ???
I have the same issue with my laptop ASUS G75VX-T4153H with W8.1 x64 OS, so I’ve reinstalled back to v18.5.2342 until the issue has been resolved.
Thanks for the update. I would be very surprised if this was indeed caused by DND mode. Since you have it on now, in case you encounter the issue again trying killing AvastUI.exe instead - that would be my most likely culprit. Also if you can send us contents of your C:\ProgramData\Avast Software\Avast\log folder, we can have a look if we find anything strange here.
Note: even though the UI reports a restart is needed, disabling/re-enabling DND mode is applied immediately as long you have closed the programs and run them again.
Sure,
I sent you a PM with logs.
The same type here 
This version really screwed me.
It is not listed on your changelog that I can see above. But you REMOVED the ability to use leading asterisks in the exclusion list. So /My Random Folder/ no longer works… and since I do not know the user profile name that is going to be on the computer it is IMPOSSIBLE for me to create an exclusion.
You also removed the ability to use *.exe it HAS to END in … so “C:\Users\Public\Desktop*.exe” NO LONGER WORKS!
Also as I had it "\Users\Public\Desktop*.exe" does not work ether. Is the removal of your wild card support a bug or did you just do it to us intentionally?
Also… The letters in the CAPTCHA are OBNOXIOUS!!! I CANNOT READ THEM!!!
You still have not fixed the bug where the hardened exclusion list is blank unless you add something to it, click okay and then go back.
eMail has stopped working. When I run a test eMail it goes through. But when my client encounters a virus I get NO EMAIL AT ALL!!
Otherwise… great product! Love it dearly… It is just costing me hundreds of dollars and hours of labor so I am annoyed. Oh, also annoyed that you are willfully installing a browser on my clients computers that they DO NOT WANT! Please stop doing that. It is completely counter productive to what you are and makes me wonder.
ALSO PLEASE FIX YOUR CAPTCHA! I HAVE BEEN TRYING TO ENTER IN LETTERS FOR THE PAST 10 MINUTES.
Reported to Avast. Hope this helps.

Your new Do Not Disturb Mode causes windows push notifications user service to stopped working and appear as application failure in reliability monitor.
I see people start complaining about issues, may I suggest implementing beta versions for volunteers which people can use and report issues before launching the update to everyone else? There are a lot of people which don’t use forum for fixing solution but simply uninstall if something not work and you lose important amount of users.
