Maybe Kas uses a .tmp dropper or something for the update. That would get ERP's attention. I guess OSArmor could cause the same problem if you didn't see an alert or it was too late to exlcude, etc.
I just noticed something very strange on this main system I use

Where is the Program Data Folder LOL? I just checked and it's in the most recent backup the system. How is the system even running? W764 btw if anyone has seen anything like this before. Just noticed it fetching the NVT logs path, which is here:
C:\ProgramData\NoVirusThanks\EXE Radar Pro\Logs
Look around the time of the last failed attempt by Kas and see if NVT records a block.
EDIT: LOL, I have run for so many years with hidden files unhidden I didn't even realize Program Data is a hidden folder. Google is the friend yes. That's what I get for feeling confidence to hide the hideable...
