Side note: UDP port 4321 uses the Datagram Protocol, a communications protocol for the Internet network layer, transport layer, and session layer. This protocol when used over PORT 4321 makes possible the transmission of a datagram message from one computer to an application running in another computer. Like TCP (Transmission Control Protocol), UDP is used with IP (the Internet Protocol) but unlike TCP on Port 4321, UDP Port 4321 is connectionless and does not guarantee reliable communication; it’s up to the application that received the message on Port 4321 to process any errors and verify correct delivery.
Because protocol UDP port 4321 was flagged as a virus (colored red) does not mean that a virus is using port 4321, but that a Trojan or Virus has used this port in the past to communicate.
