Which port are used by Viruses? TCP or UDP?
Answers were Sorted based on User's Feedback
Hi all, for this answer, this is the only possible
explaination i can give... :)
UDP Port 137 is connectionless and does not guarantee
reliable communication; it’s up to the application that
received the message on Port 137 to process any errors and
verify correct delivery.
Because protocol UDP port 137 was flagged as a virus
(colored red) does not mean that a virus is using port 137,
but that a Trojan or Virus has used this port in the past
to communicate.
This above answer we can consider as one of the example.
Still we have lot many things to explain in this ragards..
