The last several releases are being flagged by Malwarebytes as ransomware and quarantining with a reboot. From what I could see it was one of the .z extractions that was being downloaded/expanded when it happens. If there is a log file that will help you let me know and I will attach it.
Below is the text from the notification:
Malwarebytes Premium:
