McAfee security suite

I am getting a 403 Forbidden message and I would like to see if McAfee blocked it.  When I went to the firewall settings, I couldn't find the individual list of programs, so I went to help.  When I click on the link for Help I get a blank window.  When I click on Cox Secuity Suite Support I get a window with the McAfee heading and then it says an error occurred
