Turn off or turn on AutoBlock
Norton AutoBlock stops all traffic between a device in your network and any other computer
that attempts to exploit that device. Since this includes traffic that may not be malicious,
AutoBlock only stops the connection for a limited time after it detects a threat. You can specify
the period for which you want your Norton product to block the connections from attacking
computers. By default, your Norton product blocks all traffic between your computer and the
attacking computer for a period of 30 minutes.
If AutoBlock blocks a computer or computers that you need to access, you can turn off
AutoBlock.
