CurrPorts displays the list of all currently opened TCP/IP and UDP ports on your local computer.
For each port in the list, information about the process that opened the port is also displayed. This display includes the process name, the full path of the process, version information of the process (product name, file description, and so on), the time the process was created, and the user who created it.
Also, it allows you to close unwanted TCP connections, kill the process that opened the ports, and save the TCP/UDP ports information to an HTML file, XML file, or tab-delimited text file.
CurrPorts also automatically mark with pink color suspicious TCP/UDP ports owned by unidentified applications.
