This process is only using 4xx kb of RAM, however, I did catch it using 4xxx. Searches all describe it as a service only needed for the MS XP firewall (which of course disabled) or for network sharing. Although I’ve ended the process several times (via Task Manager only) it still returns, especially on reboot. I’m hard wired to a Linksys router, however, none of my children are home so wireless is turned off. There are over 200 opinions at this link making it a very confusing issue!
