Strange bug for a stable release, misleading and confusing on most parts. It re-enabled after a restart, thanks.
Hopefully the devs can push out a fix soon.

Thank you for your suggestion. But, it did not work. I ended up uninstalling the new “behavior” component in Avast, reinstalled MS Office and was able to open the xls files that resided on the main computer. But, that only lasted for about half an hour or so. Then suddenly when trying to open the very same file I got the same “cannot open file” message. I was NEVER able to open any of the files on the networked computer even after uninstalling the behavior component, turning off all the other shields, and reinstalling office on that machine as well. It just seems more than a coincidence to me that I have been using these files for years and this behavior only started after updating Avast. ANY HELP OR ADVICE WOULD BE GREATLY APPRECIATED AT THIS POINT. I am able to open all other things across the network just not these xls files.

David, Downloaded the full off line installer for Avast Free and did an over the top install. Beta indication is now gone.

That’s handy, I though for sure it would need a clean install to take you off the beta channel. Thanks for the information.

I just spent many hours trying to track down what had happened to my Oracle VirtualBox VM. It had become extremely slow. (NO, I am not using Avast inside the VM). Avast is on my host machine. First, avast jumped on the VM and declared it a ‘game’ and put it into some select list. I didn’t think that should be a problem. But when the problem persisted I took it out of the ‘gaming’ list. I DISABLED the Avast Shields (after unplugging the internet cable), and the problem persisted. So I went looking at VirtualBox and the internals of my VM (including its BitDefender antivirus). The VM was SO SLOW that it took forever for me to iterate through the multiple attempts to solve the problem. Several hours later, and my beginning to think my VM was completely broken, I finally decided that the problem MUST be Avast.
I was getting convinced it was in Avast. I looked and found an exception list, and added the VM to that list. No joy, even after re-booting.
I was getting prepared to uninstall Avast for a test. Instead I discovered ‘passive mode’, (which for the life I don’t know why this is different than turning off all the shields).
The problem vanished. I turned Passive mode OFF, and the problem was still gone. I was happy! At 1 AM this morning I was finally ready to shut down and have a bit of sleep.
This morning, I was writing this up for you folks, (who have not responded yet to my emailed problem report), and I just now decided to test the VM again. It is again completely screwed.
I am not happy. I have lost several hours of development time. This is a clear indication of SEVERAL things being wrong. I have been a loyal customer of AVAST and have recommended it to many of my friends, customers, and family. Of late the corporate mentality seems to be ‘grow, grow, grow’, all the while producing something that is ever so slightly aggravating and intrusive than much of the malware you are supposed to be protecting me from.

Settings → Troubleshooting → disable hardware assisted virtualization. Haven’t tried my VM yet but i guess that might help.

I see - I can be happy with my decision to stay with 12.3.2280

already have version 10 installed!
Comodo 10 and avast were working fine until avast upgraded!

And that’s mostly because of idiotic way how Comodo’s “Default Deny” operates. They just sandbox unknown stuff without asking user, breaking anything that was trying to update or install, potentially complicating everything even further because it’ll only partially install even if user knows it’s safe and would most likely allow it and all would be well.

I noticed that same thing. Since I have had the new avast, I noticed my VM was noticeably slower than it was with avast 2016. When I opened windows explore, it took 1 second to render the window from the top to the bottom. Before, it jumped straight to screen without rendering slowdown
I will try to disable hardware virtualization to see if there is any improvement

They don’t mess up with Avast because they have it excluded. AVG is another story (that means it was no fun with both of them :-[ ). I have both of them and i am not experiencing this issue yet.

No difference. They are both safe programs and should have been excluded.
Comodo has it’s own rules.

The same situation here. I spent 3 tough hours by investigating why almost any of my programs can’t be executed after Windows start. I was soooo close to start reinstalling my Windows 10 completely. Then I found this thread. After uninstalling Avast in Safe Mode (it was not possible in normal operation) everything went all right and all programs were running properly. So I downloaded last version of Avast Antivirus and installed it back. It crashed at the and of installation leaving Avast Service running but UI could not be executed again as well as any other program. So I went to Safe Mode again, got rid of Avast and everything is fine right now.
So dear guys in Avast!!! Please do anything to fix it up ASAP!!! I can’t use the VPN as well, while I’m paying for it!

Huh? It says 2286 is the latest. Also, strangely huge version number jump…

Rejzor, if you look at Settings > Update > Program Version
You will see Program Version followed by the build. The build changes are minimal.
DavidR
217
That’s the build number not version, which is still 17.1.2286.

Good evening Rejzor, I do not remember if you remember me, but yesterday you told me that he would make an update today and I wanted to know if his had been done?

Sorry if I don’t remember you specifically, I’m terrible with remembering people unless they have a memorable avatar 
Yes, the update was released, just not through a regular “big” update channel.
For example, Game Mode now adds games as separate entries and there is also new setting for Game Mode which prevents automatic adding of games/apps to the list. One of things I personally was waiting for a long time. They just have to fix the name of the setting because it’s a bit terrible at the moment…

- Game mode - helps reduce distractions and lag times by automatically prioritizing your game’s performance and suspending all unnecessary background notifications and processes while you play
Game mode detected Windows 10 sticky notes as “game”. I turned game mode off. Also my games work perfectly and I don’t want third parties messing with system process priorities etc…
UI seems to be slower, takes more time to appear and does not feel as responsive as Avast 2016.
O the plus side:
Wi-fi scanner interface is cool
though it’s name a bit confusing since my PC is desktop and has no wifi 
Websites load faster and Windows boot faster.
