Windows 10 disk thrashing due to CIS

Recently acquired a new PC with Windows 10.
For the most part it runs fine, but every so often the COMODO Internet Security (CIS) causes the Disk utilization to shoot to 100% and I can hear the disk thrashing going on.
I use the Windows Task Manager and sort on Disk Utilization and the CIS is highlighted at the top of list. Nothing else is close.
This was not the case on Windows 7.

Are there any CIS setting known to cause this on Windows 10 or know what settings I can change?
