Problem only happened after the W10 Update so I have to run the shield after fully booting up. If I modify and untick the Browser check the computer boots up with Behavior Shield intact.

Was this a one-time event (after win 10 update) or is it happening continuously?

Have you tried to Repair Avast via the UI.

Yes, but as it took 2 hours and was still churning away I came out of it. How long should a repair take?

Hardly 5 minutes.

If Repair doesn't fix the problem, try the following:
If your Avast settings are not the default settings and you want them restored after the Clean Install, follow this before removing Avast.

I am also noticing this issue after last week's Windows 10 v1809 update (KB4494441). On a couple of days after I boot up my computer Avast displays an exclamation mark that the behaviour shield is off - I just restart the shield so no big issue. It didn't do it yesterday but it did again this morning. v19.3.2369, not the very latest.

Try 19.4.2374
I'm not seeing this issue in the latest Stable version or latest beta with my installations. :)

I am using 19.4.2374 in which the  problem is happening.  I was going to follow schmidthouse's advice to resolve the problem when today the laptop booted up without the problem.  Yesterday I went to modify and unticked the Cleanup box as I use Boostspeed to cleanup with so am wondering if this may have resolved the Behavior Shield problem.  Out of the three computers here the W10 cumulative update installed twice, once on 14th and again on 16th on this laptop.  It appears that this is not normal and MS are looking into it. I have not restarted this laptop since booting up this morning so perhaps the problem may appear again on another startup.

Thanks for the mention, however credit for the advice/instruction given, goes to 'rocksteady' and 'Be Secure'
I hope all resolves.  :)

as long as they did their job. :)

Hi Bob, of course, I personally am fully aware of that and have been since you first put the instructions together. ;)

I was just referring to the directions given in this topic that were links to your instruction.

I did a power down and bootup late yesterday and the Behavior Shield kicked in ok. This morning the problem returned so I will carry out the instructions given to resolve it.
