Unable To Boot Windows 10 Pc

Hi All
A friend has just dropped off a PC for me to look at, but I'm stuck.
The windows 10 system starts then gives a blue screen with the following message
"Your pc ran into a problem and needs to restart"
The error is "critical process died"
It loops between this and diagnosing problem, rebooting each time.
Apparently the PC failed to sync emails just before it was rebooted, which leads me to think either a virus or failed update.(Are they the same?)

I have tried starting in safe mode - no difference, so tried "debugging mode" and it created the following file in D:\windows\system32\logfiles\Srt\SrtTrail.txt

I've pulled the drive from the machine and popped into to a USB dock on a spare PC to access the log files
It looks like there are 6 dodgy files (in red here, below)
I've tried looking at the security info, but the security tab is blank.
I've tried running cacls.exe but that tells me it cannot find the file (that IS listed with a dir command!)
I've even booted up on Ubuntu to rename or move the files but that tells me it is "unable to perfom the task".
Windows will not rename nor move the files - with an "access denied" or "cannot find files"
How should I attack this?

AVG ran on the drive and found nothing untoward.
Any help greatly received

Log files attached
Hitman Pro found a few items that it feels is malware, but I have installed.
Ahk2Exe, Service_KMS are used on this machine.
I installed Tor browser, and asumed the obfs4proxy is part of the process
Unlocker1.9.2 was an attempt to delete the locked files.. (it failed, so can be removed - as can Tor browser)

I do have a concern that the scans all seem to be onthe "C:" drive the current OS registry and not on the additional drive (i with the issue, I accept you chaps will need a "clean slate" from which to work so I wait your instuction

Thank you so much for your help.

Thank you TimW for your amazingly quick reply.
You help is so very welcome.

I have rerun the two apps and had them remove everything, rebooted and rescanned.
Logs attached as requested

Many thanks

 

Thanks TimW
You are nothing short of BRILLIANT!!!!!!!
I really appreciate your assistance

I've had a message asking me to confirm how the PC is.
It is free of malware but still not booting and I'm still unable to rename, delete or even change the ACL on 6 files in the windows\system32 directory that the diags is claiming are causing a "critical process died" As a result the system does not boot and isstuck in a loop as described in my initial post.
I reposted the thread as I (incorrectly) assumed this was the incorrect forum, now the system is malware clear.
Sorry.
Any assisance greatly received.

 

Thanks TimW.
I had, and they deleted it telling me it was a duplicate to this and that I must update this thread (as above).
I guessed it would then be moved to Software.

Not to worry. Thanks to you and your kind help I have now resolved the issue.
This thread can be closed.
I really apprecite all your assistance. Keep up the good work!
With kind regards
