You can compare your settings with this screenshot/attachment. Please make sure that you have "Enable streaming update" ticked/selected.I confirm the problem, I use windows 7
My settings are the same as the screenshot, thanks.
While i have your attention and as i didn’t want to start a new thread if its partof the ongoing problem you are fixing, could i ask if the current problem is also effecting the right click (on the system tray icon) and update option, i noticed it doesn’t load the update page it sits there with a small circle going round and round (see screenshot below) i now have to open avast then click menu, settings and update to get the update page in the screenshot in my earlier reply to appear.
Hi,
I have 191012-6 too & streaming updates on & ok.
Glad to know it’s getting fixed.
Thanks for the crucial tips & up-to-date info.
Must have typed a dozen Google searches to finally end up on this “savior” thread lol. :o 
Now I can head up (or down) to bed feeling safe 
Good night or day, folks
The list continues to get longer 
I have just turned my laptop on and have 19101506 as the last def streamed at 16/10/2019 12.02 - normally the def would be 1910,Current date,00etc so that is now lagging date wise as well.
Streaming updates is on but nothing has been received since 19101506 - ie no streaming for the 16th October which seems strange.
Streaming updates are working.
There is a problem with VPS updates that’s been acknowledged by Avast.
So you are still getting updated protection.
My query is that no streaming updates for the 16 October appear in the defs folder - normally there would be 2 by now but there is nothing since 19101506 which is what I’m querying - at least there should be 19101600 ??
Things have got a bit stranger in that the defs folder shows 19101506 as the last stream but with the date and time of 16/10/2019 14.59 ( was 12.02). It seems any streaming is now being included under 19101506 rather than being 191016XX ?
For me is happening the same.
…and longer yet. I wonder if there is a point at which the list could become too long and we would start losing protection?
You would continue to be protected. What I’m having to consider at what point does all of the collation of these streaming updates (into a single database) becomes CPU/processing/scanning intensive.
Same thing here. :
Agree with conrad1961 & fvmb.
I have posted this in another virus definitions topic:
Whilst this is in the Avast Business forum, I pretty sure it is the same issue effecting the Avast Free Antivirus / Premium Security products. So it is being worked on.
Please don’t contribute to this Avast Business forum topic in the quote unless you are actually using that product.
It would appear that there has been some progress, we will have to see in the next couple of days.
The size of my defs folder has reduced drastically as I have received an Auto VPS Update 19101506.
Up from what was 19101206 but nothing for today yet.
See Reply #23 attachment of my previous defs folder state.
Is Avast for Windows currently receiving virus definitions updates? I uninstalled Avast from my computer some days ago due to the problem with definitions updates. However, I’ll be happy to reinstall it if the issue has been solved and Avast is getting virus definitions updates again.
Please, let me know. Thanks!
Lucky you, I’m still stuck on 191012-6.
I also have 1910506.
Avast updated today on my Systems
It is progress but I’m not sure that it is helpful. At least here, streaming seems to have stopped. I have a 1910506_stream directory but nothing in it with a date stamp later than 16/10/2019 07.47 and there is no later _stream directory
No it wouldn’t be good if they fixed one but broke the other as essentially the streaming updates are more important.
