Symantec keeps blocking traffic from the IP of my Comcast SMC Network gateway. It blocks traffic because it is detecting a UDP Flood Attack. According to the log the CPU usage is spiking to 100% when this attack occurs but Im not seeing this spike in the performance monitor. Symantec also detects a UDP Flood Attack when I am connected to my home network from what I assume is my home modem.
Is this a legitimate attack or a false positive? What could I do to stop the attacks?
