Norton Family crash in Chrome

When my son tries to use Google Chrome, he gets a message saying 'Norton Family has Crashed' at the top of the screen and a button to reload.  When he hits reload, it just comes up again.  We're running the latest version of Chrome (39.0.2171.95) on Windows 8.1 and I believe the latest version of Norton Family (3.2.0.14).  He doesn't have this issue with IE, but he prefers to use Chrome.  Any ideas on what I can do to stop Norton Family from crashing?
