This is a tool to watch all open ports (both TCP & UDP) and active network connections used by process. It will help you to find out any suspicious network activity on your system. You can detect any trojans, malwares which are continuously sending keyboard strokes, browsing data or any secret information to the remote system. By looking at active connections, you can easily find out the remote machine and associated remote port. This information makes it easy to detect any illegal activities as well as to trace the remote system.
