The eapihdrv service failed to start due to the following error (normal?)

Update in reply 

I ran a scan today and noticed this in my addition.txt file. I'm wondering if this is something safe or something that should be fixed?
I ran scans with everything else (malwarebytes premium, sophos, adaware scanner that MB has, msert, and esetonlinescanner) like I did last time and nothing was found.

Text from it below:



Error: (06/01/2022 03:50:19 PM) (Source: Service Control Manager) (EventID: 7000) (User: )
Description: The eapihdrv service failed to start due to the following error: 
This driver has been blocked from loading

Error: (06/01/2022 03:50:19 PM) (Source: Application Popup) (EventID: 1060) (User: )
Description: \??\C:\Users\kacie\AppData\Local\Temp\ehdrv.sys


I went to the directory but couldn't see that file at all. I don't know what the file (ehdrv.sys) is for, so I don't know where to even start with it.

I have also attached the FRST and Addition files to this post (the Addition file is what holds this text)

Added the "addition" txt from today's scan, it's still showing up there. I'm not sure what the file is or does, but if it's not malicious then that would be great. 

I'm not getting any popups on my computer or anything like that. Nothing is acting strange from what I can tell. I just scan my computer a lot, so I saw that and began to worry.

Update: I googled ehdrv and it seems to belong to the ESET Online scanner? Which is what we scanned with the last time when checking my computer. So this is safe and I shouldn't worry?

You should be able to delete the following manually @kelizabeth

  • Read and accept the disclaimer.
  • When the tool opens, ensure all boxes under Actions are checked.
  • Under Delete Quarantines select Delete Now, then click Run.
  • Once complete, click OK.
  • A log will open in Notepad titled kprm-(date).txt.
  • Please attach that file to your next reply. (not compulsory)
