Norton Internet security. When it opens It comes up as a White screen

Hello,

 I was trying to open my Norton Internet security, I was not on the internet and when I clicked the icon on my desktop it didn't work so I went to the little tool bar at the bottom and it opened when I clicked that but it opened as a blank white page and I don't know what to do. My Norton Utilities works just fine.

 

I am running on windows 7. Please help.
