Title: "Behaviour shield is now off"
Post by: Cliff_g on October 02, 2018, 09:02:54 PM
Been getting quite a few of these recently, behaviour shield turns itself off.  Turns on manually OK, but for that I have to notice it is off.  version is 18.6.2349 build 18.6.3983.371  Win 7 SP1 fully patched.

Any ideas anyone? Bugette? (that's the conclusion I come to from previous instances of this that folk have mentioned)

Try a 'Repair'
Control Panel/Program&Features (Add and Remove)/ Select Avast choose Uninstall, then select 'Repair'
Reboot :)

I have found this to occur when I try to open a program too early after the desktop appears and it also depends on how many startup items you have. Try waiting a few minutes after the desktop appears before taking any action and see if this helps.

Interesting, thanks. Will see if I can spot any such pattern.  No start-up items other than basic Windows stuff

Just FYI - Same problem here, intermittently on my Win 7 Pro 64-bit machine.  My Avast Free is version 18.6.2349 (build 18.6.3983.371). 

Yes, I have quite a few programs turning on when I reboot my Win 7 Pro 64-boot machine (with 16 GB RAM), such as TeamViewer Free resident, SpiderOak, PCloud, OneDrive, iReboot, Start Menu X, MalwareBytes.  Shouldn't Avvast play nice anyway and not occasionally give me a warning that somehow the behavior shield is off? 
 
Thanks.

 Not sure if this is the right forum topic, but all of a sudden my web shield has turned off and I cannot get it to turn back on.  I am on Avast Premier (could not find the version number), Lenovo Win 10 OS, 64 bit, not sure of the version number but have had the laptop for approximately a year.  I have had the shields get turned off before but never a problem turning them back on. A reboot was done with the same results, could not turn that shield back on. I have used Avast for many years with very few problems which were usually minor.

Appreciate any suggestions to try.

Please try the following: Repair Avast:
Control Panel> Program and Features (Add/remove program)>Select Avast> Select Repair. Reboot when completed
https://www.avast.com/faq.php?article=AVKB204

If Repair doesn't fix the problem, try the following:
Clean Install of Avast:

awesome … thanks  for  the  tip,  lucas.

couple  minutes  after  booting … avast  notified  me  the  "behavior-shield"  was  disabled.  quickly  checked  avast-forum … realized  i  had  acted  a  bit  hasty,  initiating  a  certain  program  on  my  computer … decided  to  take  your  advice.  rather  than  engaging  b-shield  manually … i  simply  rebooted … this  time,  giving  adequate  time  for  avast  to  engage  itself … only  then,  did  i  initiate  the  program  in  question.  voilà … avast  started  with  b-shield  fully  intact.

thanks  again,  lucas.
