Nvidia Firewall (Network Access Manager), according to this thread :

It was probably installed with the chipset drivers the last time I formatted my pc... which was probably back in 2006.
Also when I disable my windows firewall, the security centre still thinks I have a firewall running; there's three task manager processes that confirm this:
nSvcAppFlt.exe
nScvIp.exe
nSvcLog.exe
A fourth nvidia process is
nvsvc32.exe
is related to my graphics driver
Guess I'll be removing the NAM then
