I dunno where did this come from. I just noticed it when I was connecting to the PC on my LAN and it's there. Getting Info about it gives me nothing. Just the "Mac Server" thing. I cannot access anything from it. Is it a virus? Or someone has been able to connect to my network and hogging all my WiFi? I'm not quite sure, because I have a secure password for my router so I really don't know what / who it is.
