Hi, I recently assembled my own PC using a supposedly brand new motherboard but one that doesn't come sealed in any way when delivered. So I got worried and came across Eset as one of the few AVs that can scan UEFI or BIOS for viruses/malware. But I'm having some trouble using the scan. It seems to be unable to scan the BIOS/UEFI files as it can't open the necessary files for scanning. I read some other posts in this forum regarding the "unable to open" log messages but the answers given were not clear to me as a non techie person.
I tried scanning the UEFI through "Custom Scan" -> "Boot sectors/UEFI" and ran the scan as Administrator. Below is the resulting log:
Log
Scan Log
Version of detection engine: 26208 (20221105)
Date: 6/11/2022 Time: 5:09:28 pm
Scanned disks, folders and files: Boot sectors/UEFI
\Device\HarddiskVolume1\EFI\Microsoft\Boot\BCD - unable to open [4]
\Device\HarddiskVolume1\EFI\Microsoft\Boot\BCD.LOG - unable to open [4]
Number of scanned objects: 141
Number of detections: 0
Time of completion: 5:09:28 pm Total scanning time: 0 sec (00:00:00)
Notes:
[4] Object cannot be opened. It may be in use by another application or operating system.
My questions are the following:
-are the files listed in the log as unopenable supposed to be unopenable or am I using the scan wrong?
-If the scan is unable to open those files detailed in above log does it mean that my BIOS/UEFI is clean?
-If the scan is able to open those unopenable files above does it mean that my BIOS/UEFI is compromised in some way?
-according to the following link Eset will be able to scan those unopenable files during startup and shut down but I can't find the logs of those scans happening during startup or shutdown. Why? (link: https://support.eset.com/en/kb2155-error-notifications-in-computer-scan-log)
