Network attack while installing game

Im using bullguard anti virus and was installing the new cod update when it popped up saying my network was attacked from this remote “ ( level3. blizzard. com )” and a follow up attack from “” it says it was a port scan, should I be worried?

I’m having the same problem, I too get these messages of network was attacked, and they started coming when I installed the client. Have you figured anything out?

Same thing to me. Bullguard reports several port atacks. The ports atacked are:

  • 50811 tcp
  • 50913 tcp
  • 50849 tcp
  • 50815 tcp
  • 51034 tcp
    Please answer us, so we can know if it’s a false positive at least.
    And … Thank You.

Should I be scared or
