Norton Security 6 for Mac has seized functioning after OS X 10.10.4 instal

Hi,

After I installed OS X 10.10.4 my Norton security 6 has stopped working and it constantly warns me that you are at risk and it shows that

it is disabled!!!!

Please help me fix as whatever I try to fix and enable it again it doesn't work.

I have subscription for another year and half remaining!

Thanks
