You suspect that your Windows machine has been compromised with a Trojan virus. When you run anti-virus software it does not pick of the Trojan. Next you run netstat command to look for open ports and you notice a strange port 6666 open.

What is the next step you would do?

A.
Re-install the operating system.

B.
Re-run anti-virus software.

C.
Install and run Trojan removal software.

D.
Run utility fport and look for the application executable that listens on port 6666.

Explanation:
Fport reports all open TCP/IP and UDP ports and maps them to the owning application. This is the same information you would see using the ‘netstat -an’ command, but it also maps those ports to running processes with the PID, process name and path. Fport can be used to quickly identify unknown open ports and their associated applications.
