For several days my Norton I.S 2011 v.18.1.0.37 shows that I am Idle when I am using the computer and even when the computer is turned off. Is there a problem or bug in my norton ? How do I Fix It ? And I am getting almost weekily notifications that I must register my product. I Have done it in september 2011 and since the my PC crashed several times and I was forced to reinstall the security product. Does somebody know how to get rid of the Register notification and the performance bug mentioned above ?
