Eset has no use for that process but malware can be deployed via it: https://lolbas-project.github.io/lolbas/Binaries/Atbroker/

You might want to use SysInternals Autoruns and see if you can find any reference to AtBroker.exe in any of the Windows startup locations; e.g. registry keys, startup directories, etc..

Is your copy of Eset legit and downloaded from the Eset web site?

Use of Windows "Assistive Technologies" such as Magnifier, On-Screen Keyboard, etc.. are most likely the reason for AtBroker.exe to load at boot time. Are you using any of those features?

If you don't want to use Autoruns to determine what is starting AtBroker.exe at boot time, do the following. Create on a test basis an Eset HIPS rule to allow the startup of AtBroker.exe.  Make sure you enable logging for the rule and set its severity level to "Warning." After you boot, check the Eset HIPS log for any log entries from this rule. Those entries will inform you what process is starting AtBroker.exe. You can now delete the HIPS rule for AtBroker.exe.

If ekrn.exe is not starting AtBroker.exe, then Eset is not the source of the activity.

In regards to the HIPS rule it should begin with "User rule:" followed by some descriptive text. For example;

User rule: allow atbroker.exe startup

 As far as the first rule screen goes:

Action = Allow

Operations affecting - checkmark "Applications"

Enabled - checkmark

Logging severity - Warning

Click on the "Next" tab

The next screen shown is titled "Source Applications"

In the drop down box select "All Applications"

Click on the "Next" tab

The next screen shown is titled "Application Operations"

Check mark "Start New Application"

Click on the "Next" tab

The next screen shown is titled "Applications"

Click on the "Add" tab

Enter both atbroker.exe files from windows system32 and syswow64 directories

Click on the "Finish" button

Click on any subsequently displayed "OK" button to save your newly created rule.

Verify your newly created HIPS rule conforms to the above settings by reopening the HIPS rule you just created.

Eset is not causing atbroker.exe to run at boot time; that I know as a fact. I have spent enough time on this thread.
