When Norton Internet Security detects an attack, it

AutoBlock, which automatically blocks all incoming
communication from the attacking computer for a set
period of time, even if the incoming communication does
not match an attack signature.

need to access, you can turn off AutoBlock. Make sure to
turn AutoBlock back on when you are done.
