Okay, I restarted my MBP dude to it not recognizing my external HD or USB sticks, and after it had started back up, I keep getting these pop ups asking me to 'allow' or 'deny' to connect to 'port' or something.. I have no idea what is going on, there is a new icon on the tool bar at the top of my desktop, when i hover my cursor over it says "show/hide network monitor" Have I done something wrong? Becasue every programme/app i open it pops up with "etc etc would like to connect to port80" etc.. I've attached some pictures, please someone help. Thanks.
