Side note: TCP port 4000 uses the Transmission Control Protocol. TCP is one of the main protocols in TCP/IP networks. Whereas the IP protocol deals only with packets, TCP enables two hosts to establish a connection and exchange streams of data. TCP guarantees delivery of data and also guarantees that packets will be delivered on port 4000 in the same order in which they were sent. Guaranteed communication over port 4000 is the key difference between TCP and UDP. UDP port 4000 would not have guaranteed communication in the same way as TCP.
Because protocol TCP port 4000 was flagged as a virus (colored red) does not mean that a virus is using port 4000, but that a Trojan or Virus has used this port in the past to communicate.
