I'm having lots of issues with my computer freezing up. When is does, task manager shows 100% CPU followed by 100% DISK. Watching processes in task manager while stuck at 100% DISK, I got a quick glance at E_DISKSD.EXE. However, it disappears from the list of processes; I can't find it with file explorer; and I can't find it searching the internet or Avast forum. I don't know if it has anything to do with my computer freezing up and am hoping that someone here has seen this problem.
