title: Jupyter notebook: connection to kernel restarts infinitely
body: <p>I just moved on to a new PC at work, installed Anaconda.
  When trying to run a notebook I see the "connecting to kernel... connected to kernel" message flash to infinity with an icon saying "No connection to kernel".
  It appears as if the connection gets killed after starting.</p>

  <p>Another person at work in my room has the same problem, so perhaps it has something to do with the antivirus or domain systems at work.</p>
  
  <p>How can I get my jupyter to work?</p>
