Block one malicous website, but after that nothing?

So, I just need to have this question answered. The past few days my Malwarebytes software has blocked over five malicious websites from clipconverter.com but my Norton Anti-virus has blocked one website once. Does the anti-virus do one block and doesn't notify me after that or did it deactivate? I know I won't be going that site again any more, but if anyone can answer this question I would really appreciate it.
