CPEPMON.MLF Growing

I have a file in my windows directory CPEPMON.MLF.  It grows at a very quick rate.  The only google reference is to a old forum question here.  Tried every single remove tool out there.  None of the tools detect it as a virus or malware.   It is not a windows file and access is denied to delete it in safe mode or safe mode command prompt. It shows in use my the process SYSTEM PID:4

I was able to delete it once,  but it came right back and now wont be deleted…
Ill pay to find out what this is
