Firewall Listing + 20 host? what does it all mean?

Hey Guys
Just new to this. My question is on the above screen comes up a list of apps on the host + eg. firefox and all these ? address eg. atlas.c1or.facebook.com & mini facebook. Was not logged into facebook. Does this mean someone is accessing my facebook page??What does this mean. Anyone any ideas please enlighten me.

I have the Norton Premium.

Facebook tracks you on lots of different websites you may be visiting. It doesn’t mean someone is logged on to your Facebook account but we just show all hosts your PC is communicating with.

Hi Ken Just want to further elaborate I wasn’t on any of the sites that came up. Eg Facebook, ect.
