I run windows 10 and avast. Disk at 100% most of the time. After a week of trying all the solutions offered in various threads, with short-term results then going back to 100%, I turned on Windows Defender Anti Virus. So far disk is low. Even stressing the cpu results in short-term high disk, but then it goes down. Just FYI for others to try.
Add another item. Avast uses hardware acceleration, disable it and any other hardware acceleration used by any other programs.
Hopefully the last addition 01.05.18: This has cured the problem for the last three hours running a variety of situations that caused 100% disk utilization before the fix. From the command line, I ran the chkdsk.exe /f /r and replied "Y" to the question (worded close to this) do you want to run check disk the next time the PC reboots? Check Disk ran for about an hour and then I had to reboot several times as it was fixing disk errors. Finally it completed a reboot and has been running fine with very low disk utilization.
Hope this helps someone!
As of 01.08.18 no more high disk utilization. On 01.06.18 Rolled back changes made in attempt to fix problem. Re-installed Malwarebytes. Everything is running fine.
update: as of 01/28/18 no issues. Problem solved.
