Looking through Processes in Task Manager on my WinXP machine, and
noticed NMAPSERV.EXE.

I have NMap Win installed on my PC, which I downloaded to play around
with; but is it necessary for NMAPSERV.EXE to be running in the
background, even though NMap is not open or being used?

I checked nmapserv.log, and it didn't seem to be collecting anything
important about me; is NMAPSERV.EXE some kind of spyware that came witn
NMap Win?
