After 3 weeks , Norton support team was not helpful at all. The technicians are not qualified and even they did not know about Intel anti theft. The average pickup phone was more than 30 minutes and in some cases 1 hour ! (they transfer calls between people. However they could easily add a number to divert the call to anti theft department). One of the worst experiences ever I had and definitely I am considering moving to another vendor !
Anyway after lots of research I found the problem myself. The problem was "Intel Management Engine Interface" , I downloaded from my laptop manufacturer and now it seems fine.
