Yes, this is an x(86) desktop. The problem started after upgrading it from Win 10 1709 to 1803. The problem does not occur on a laptop x(64) upgraded to 1803 on May 6. The problem also not occurs on a laptop x(64) still on Win 10 1709. All 3 are running ESET Internet Security 11.1.54.0. So based on this it seems it is an x(86) related problem. Just disabled "disabling protected service" and rebooted. Lets see what happens.. Thanks, your instant response is much appreciated.

Rebooting makes is go away for a while . The system was rebooted today at 17/05/2018 14:49:19. And as you can see from the earlier ESET log entries the error re-occured at 17/05/2018 17:08:01 and 17/05/2018 21:08:03 Can you explain what you mean with "disabling protected service" .. The setup shows "Computer protection", "Internet protection" and "Network protection" all with various options.

I have exactly the same issue. The problems started after upgrade to 1803 on May 5 2018. It has been restarted several times since then. Below is a summary of the ESET events since the "Feature update to Windows 10, version 1803" was installed. No such errors prior to that date.. As this has been reported several times during the past weeks I wonder what the solution is (if any). Time;Module;Event;User 17/05/2018 21:08:03;ESET Kernel;A serious application error occurred.
