The Behavior Shield blocked too many normal apps. NVIDIA Share.exe, runonce.exe, OneDrive.exe, iCloudDrive.exe, etc.
The "minimal protection" it is very important.


Any chance you could post at least the screenshots of the detections? It would help me a lot to analyze the problem :)



Yup, something is wrong with Behavior Shield. It's just not detecting things AVG is detecting with Software Analyzer. Exact same things. My sample of Vipasana ransomware for example. AVG blocked it no problems, avast! BETA with seemingly identical component for behavior analysis and blocking, got through and encrypted files.
Could you please share the hash of the sample you used for testing?

Are you an Avast employee?


Yes.

Please let us be sure the Final Release is really ready with no bugs. This is why a few months ago, I suggested and still reiterate that Avast should not be making all new releases every month. Too much can go wrong with just one or two lines of wrong code. Better to say, just release 2 updates a year. One mid year, one end of year. The actual engine in the program seems to be doing quite a good job, so very little tweaking needed there.

Thanks. Quick question, you are testing without network connection right? Or did you change Avast configuration besides turning off File Shield?

Yes.
Waiting for Vlk to confirm.  :-\

I believe he is, just that his forum profile hasn't been updated yet. But I have sought confirmation.

What has been asked for, an image of the alert and hash for the file doesn't present any security issue, regardless of who was asking for it.

Does Software analyser in AVG and Avast (in beta) have same ability for protecting from unknown/new malware?

Hun_Bolt is indeed an Avast employee, in fact one of the key people behind IDP / Software Analyzer / Behavior Shield. Please treat him well!!  ;)

The forum admin will update his forum account soon.

Thanks

You took my words from my mouth. Too good questions for a person with... 1 post and no Avast badge.  ;D ;D Welcome aboard Hun_Bolt and sorry for the question.

1.  The menu in help still does not work for me.  If I click "?" from the main GUI, a new window opens, then if I click the bars at the upper left corner, the mouse-up event causes a menu to drop down -- But this menu goes back up before I can click on a help menu item.

2. After smart scan, then resolve all, there are some performance items listed.  I don't have "Avast Cleanup Premium" so there is an "Activate" and a "Skip" button at the bottom of the window.  "Skip" does nothing.  Also, at the top of the window, "Back" is a choice, and it also does nothing.

Internet connection was active, I was testing with ONLY Behavior Shield enabled. I've also tried with all the other shields removed and also all the shields installed but disabled, to see if that made any difference. From what I can tell, it didn't.

The thing is, avast!'s Behavior Shield didn't get triggered on same things new AVG got triggered by Software Analyzer despite both being the same thing now. Which made me believe there are some Behavior Shield integration issues within avast!.

Apart from behaviour shield, another problem is LANGUAGE. Yes, we're Chinese, but we often meet this kind of point where Chinese cannot regularly appear. Well, the other is Sandbox cannot also run smoothly. Last, Avast beta has come out and AVG with Avast's components is closer to final version. Well, when will the final Avast build put out? even closer to a more complete one like AVG?
