I just received the same IP block though Firefox: 141.101.124.185 (Type: outgoing, Port: 50869, Process: firefox.exe) 199.27.135.184 (Type: outgoing, Port: 50870, Process: firefox.exe) These showed up with only Facebook & Cracked open at the time. I also had a third one that I've found through a quick check: 184.82.146.118 (Type: outgoing, Port: 65506, Process: firefox.exe) I've seen them show up before, but just now thought to check on it. For what it's worth, I'm running Windows 7, & using Firefox with Adblock Plus. I'm on a Sony computer & haven't taken the time to remove all of the default Sony software yet.
