Hi Jef,

Any tasks would be in task scheduler, and you mentioned that you already
looked there. I would suggest you try process explorer to see if you can
detect what is going on:

The regularity of it suggests a timed event, perhaps a weekly full system
scan by your antivirus or antimalware product.
