To see if it's the antivirus or firewall, try turning it off to test.
Not to my knowledge. Also all the systems seem to be up and running: https://www.origin.com/en-us/status
Maybe restarting your computer will put thing right.
And if that doesn't work try cleaning the Origin Cache: http://sims4.crinrict.com/en/2014/09/delete-origin-cache-files/

Make sure to accept a solution once your issue is solved so the next user knows what the solution was and the helpers know you no longer need help.
Thank you
