Hi,When I run process explorer I'm seeing a system process listed only as "System" PID:4.No verification or any further details which worries me.I'm running Vista 64.Can anyone verify that this is a genuine process?The only other unverified process I have on my pc is MDM.exe which I believe is a debugging process. Again any comments?Al.

Hi That is actually not a process, it denotes a group of process that have SYSTEM integrity. If you add the "Integrity" column, you would see the integrity level of the proccesess in that group.To answer you second question, MDM.exe is a debugging tool.
