Error 3039, 65543

I have had Norton sometime, I have just got the error message 3039, 65543 telling me to remove any non-symantec security product.  I have not made any changes to my software in an age and have no other security products, so I am at a loss what to do. 

 

My SONAR protection is off and when I press fix now I get the same message as above.

 

Any help would be much appreciated.
