unknown.log appearing in Windows Defender Service folder

IMHO you really need a malware expert and I am not one by any means
However until you find one replying to your topic, my advice is not to run CCleaner as part of the procedure to try and eliminate the recurring found threat.
I appeciate there are many people who swear by CCleaner and its capabilities. It certainly has its place, but in my experience, even although what was Piriform and has for sometime been part of the AVAST group, has made some changes to CCleaner to make it more compatible with 10, it still remains in default mode - unsuitable for use on a general basis.

Certainly at one time it was deleting files that made Defender think that each scan was the first scan.

As I said you really need an expert in malware issues, not to mean that you definitely have malware, but to run the scans that the specilaists have available to them.

That said you mention a number of time the fact that you have deleted the history in WD service hisotry folder, but I am still unsure as to which you have deleted.

I suggest that you stop CCleaner running or even better uninstall it.

I then suggest that you verify that this
C:\ProgramData\Microsoft\Windows Defender\Scans\History\Service.

In the "Service" folder, find and delete "Detection History".
REMEMBER to empty the RECYCLE BIN

Is where you have been and deleted the items. To do so of course you must enable - show hidden files and folders in view option.
AFTER deleting them what is often missed is that you then need to FULLY shutdown the computer and reboot.
NOT merely the usual windows 10 hybrid shutdown.
You may do that either by restart which is a complete shutdown OR by
Step 1: Open Start menu, select Power button.

Step 2: Press and hold the Shift key on keyboard, while clicking on Shut down, and then release the Shift key to perform a full shutdown.

I then suggest that you open settings
Update and security
windows security
virus and threat protection and scan options and then do a FULL SCAN.

TO DO THIS effectively it is vital to disable all third party system maintenance tools and all third party AV programs, even if they are scan on demand only.

Then see what it finds.
Please post back with the results
