It's happening with only Win7 32 bit - both Free and Business versions. Resolution for now - uninstall the software.

I've just joined up to confirm this, seven machines now BSODing if Avast is running. Stopping the shields or the Avast service cures the BSOD.

Needs a fix ASAP.

First there was the problem of AVAST and AutoCAD 2011 (Win 7 (resolved through the key in the registry) and Win XP (is not solved)) after the update, after 2 days BSOD on 3 computers Win 7 32 bit. When will you fix it? >:(

P.S. Earlier Avast worked a year without problems. Better to test before release of updates

Had a Windows 7 32Bit machine running for about 30 minutes with just the behaviour shield disabled.

Previously they were BSOD every 10 minutes or so.

Experiencing the same on Windows 7.

I find that it shows bs not long after running a program.

Is this down to an update to the program this morning? as mine still shows same version.

Does disabling the behaviour shield fix the BSOD?

I've yet to try disabling anything in avast, hope it's possible without a Bluescreen appearing, can this be done in safe mode?

No need to go in Safe Mode.

Try this :

Avast UI > Settings > Components > Behaviour Shield > [untick] Behaviour Shield and disable it until next restart...

Does that solve the BSODs?

I've had to disable all shields again. It also seems that changes to the service state (so enabling or disabling a shield) can trigger a blue screen. Had several blue screen when I pushed out an update through the cloud interface!

Don't disable all of them, just the file shield temporarily.

The decision on 03/20/2017 15.21 (UTC + 03.00): Disabling AVAST forever in the tray on Windows 7 32 bit ONLY. Wait for program update

What do you advise in the meantime and will the update fix be automatic?
