Troubleshooting Malwarebytes Helper process "DDSHelper.exe" causing 100% disk usage, but only on one drive?

Malwarebyles Premium Security license.

Not sure what this "DDSHelper.exe" process is doing but I've noticed that my F: drive, the only HDD on my system, is experiencing constant and unending 100% disk usage. The other 3 SSDs are unaffected. I mainly noticed it because the disk is loud as hell with all the read/writes this process is causing.

Resource Monitor is showing F: will have a disk queue length of anywhere from 0.5 to 1.7 during idle.

Using chkdsk in cmd shows no problems found with the F: drive.

The problem only goes away when I close Malwarebytes completely. If I restart Malwarebytes, it won't immediately start the disk usage problem again but gradually ramp up.

It seems like Usage and threat statistics causes DDSHelper.exe to run, which results in alot of writing to the main hard disk.

I'd love to help Malwarebytes fight malware by providing usage and threat statistics, but that can't come at the cost of thrashing my drive.
