Like the Windows Task Manager, the a-squared HiJackFree Processes section lists all running processes. But additionally it shows tons of useful information at the details pane. File properties, loaded modules, online information and process details that indicate whether the program runs as a service, was started by an autorun entry or opens TCP and UDP ports. The Ports section of a-squared HiJackFree shows all local open ports. An open port means that there is a process running which listens on the port number for input from outside. The Ports Manager shows also the processes which listens on the ports so you can quickly see which processes must be shut down to close a specific port. You can kill a process and put it to quarantine for a later restore if needed.
