I run AVAST free 17.3.2291 (build 17.3.3443.0) on Windows 7, and now and then when booting up Windows the Behaviour shield is turned off. The Avast icon shows an exclamation mark, and when I open Avast it shows the message "You're vulnerable Some shield are turned off". I turn on the Behavior Shield and everything is back to normal. This has happend to me maybe 4 or 5 times in the latest two months.
Anyone who recognize this behaviour or know how to fix it?

Perform a repair of avast and check if it solved the problem.
If not perform a clean installation of the latest avast version and check again.

This is a known problem. Avast is aware of the problem. It should be fixed when the next version is released.

Hi,
I and Everyone I know that uses Avast Free AV has this problem with the shields collapsing and having to be reset repeatedly! Please Avast needs to urgently sort this problem!!

As noted, Avast is aware of the problem and said that it would be fixed with release 17.6.

Win XP Pro Service Pack 3
Avast AV Free Ver. 17.5.2303
Sheilds are dropping about every 5 minutes. I would not notice except for the fact that when they do drop, my browser (Firefox 52.2.1) becomes unresponsive. As soon as shields are rebooted the connection is restored.

I suggest you start your own topic since this is strictly about the Behaviour Shield which is already known by Avast.

Dear all, I have the current version [just did a check run] of 17.5.2303 (build 17.5.3585.203) and I have also occasional 'Shield' dropouts.
This does not give me confidence in using my laptop. Can Avast provide us with any updates?

Hi, it's already fixed in the beta (V17.6).
-
Do you know when 17.6 is released?

Do you know when 17.6 is released?
The short answer is always going to be a NO, it all depends on how the beta testing progresses.

Just want to report that I still have the same problem as above with the Behaviour shield after updating to version 17.6.2310. Seems like this is not fixed...

The fix seems to be dependent on which Windows OS, drivers and third party software is running. I have 3 Win 7 Pro laptops(different brands) and only one has this issue. The other 2 have never had this issue, even with earlier versions of Avast. See https://forum.avast.com/index.php?topic=208223 (https://forum.avast.com/index.php?topic=208223).

I've even used the Avastclear utility to completely remove Avast, restarted, and downloaded the latest program version (17.7.2314), and it's STILL doing this. I love Avast, and it's the only anti-virus I've used for the last 10 years. But this is becoming worrysome.

This problem started for me only the last two month but I see it is an older bug, still not fixed.
I am using Avast internet security (paid), with windows 7 pro, also for more than 10 years. When can we expect a fix?

Hi all,
we are looking for a volunteer with this problem who is willing to share with us performance log from the system. The best match for the volunteer is that the shield is off every time you reboot/start the system.
So far we can see that the problem of the start is not connected to the shield itself (it tries to run but the system is not responsive as in our environment). Therefore we cannot fix the issue (if it's in the Avast code base) w/o your help.
To maia225: we can fix only issue if we can recreate it on our systems. Unfortunately this is not the case with this issue.
Thanks for cooperation,
PDI

I spent hrs. with Lucas sending many logs, etc. Never solved the problem while I used the Regular Avast release.
I wen't back to the current beta and no longer have the problem.
Don't know what the difference is but if I use the regular (stable) release, Behavior Shield is off after you reboot the system.
When I use the beta, as I am now, All shields are on when the system starts. ??? ??? ???

Hi Bob3160,
the biggest group of reports is from W7 users and you are W10 user. I may be wrong of course.
We appreciate your help and sharing the system logs. Your system logs were checked by couple of ppl and the root cause was not found in them. The problem in your case is not related to the Behavioral Shield. It suffers only because of someone else and the system didn't even let it to start.
To my request: even if we found the possible issue in your logs. Others may suffer the same symptoms but the root cause may be different and we'd like to compare the logs from more than one user.
Regards,
PDI

Just another example of why I get so bloody annoyed when a supposed beta versions gets released and has the same versions number.
How the hell can it have the same version number and the beta works but the regular release with the same version number doesn't.
If nothing changed (the definition of the same version number) then nothing should be broken surely ?

Hi guys,
there may be small differences in the content for the offers as the beta is using different servers than release build but there isn't change in the code between the beta and release builds.
To Bob2160: the problem in your case is the slow start-up of the whole system (it starts in a matter of minutes for both beta and release) and the behavioral shield startup problem is just a consequence of it (the system doesn't give a chance to run the service in release) and to be honest I'm surprised that the shield is running on the beta build. We don't have any proof to say it's because of the Avast AV or it's because other software.

PDI

All I can add is that since being back on the beta I've never had the Behavior Shield not start at boot time.
While on the regular build, I always needed to turn the Behavior Shield on manually.

Hi guys,
...as the beta is using different servers than release build ...
Hi,
Does the agent must access the server before being enabled by system?
is there a faster access to the beta servers at system startup which could explain the system gives a chance to run the service in beta but doesn't in release ?
-
Hi Chris05,
no, it doesn't. The comment was to answer general comments about the code difference between beta and release builds with the same build number made by Bob and David. It wasn't related the problem with the shield start at all.

PDI

How many months, AVAST? >:(

Hi PDI, what logs you want? There is a Japanese user who is suffered by this issue and I can ask him/her for help.

After followng the link I suppose there is no fix in sight in the near or far future. So I might as well get used to turn it on myself. I´m a little confused that they (avast team) can´t recreate the problem. But i´m not an technician so what do I know. As I recall the problem started after an update of the avast version. I do not longer recall if it was when the bahavior sheild was introduced or if it was at a later time.
Merry Christmas

Just upgraded to 17.9.2322 - Problem still exists.

does all of you have Comodo also running on your Windwos 7 machines? I was not having this issue since yesterday when I updated my Comodo Firewall version and from that moment the behavior shield is turned off after Windows reboot. Just an idea...
Nothing else was changes in the near time...pervious change was the install of the MS security patch because of the Meltdown. But you guys have the issue mothnes ago, so....

I don't use Comodo but had the issue in the past. Haven't had it for some weeks.

I never had this issue, i just turned my pc on and the behaviour shield was off, yesterday and the past few years this never happened.

I started this thread about a year ago, and I still have the same problem with Behavior Shield being turned off.
I'm now running Avast free 17.9.2322 (build 17.9.3761.278), gonna update to 18.2.23.28, but without much hope, sigh...

Moved to this product about a month ago and have been reasonably happy with it but over the last few days I have also been getting " Behaviour Shield not turned on" warning message. O/s is Windows 7 Professional Service Pack 1. Avast is Avast Free Program version 18.2.2328 (build 18.2.3827.307)
