If you’re trying to diagnose network problems – random slowdowns or potential malicious activity, for example – use Nirsoft’s brilliant Currports. It examines all the open ports on your PC and reports their activity in real time. With its latest update, Currports is even more useful. Now the tool displays columns for Sent Bytes, Received Bytes and Sent Packets, which lets you quickly establish which ports are hogging your bandwidth. Currports won’t display this data by default – the tool needs to be running in administrator mode (right-click the exe file and select ‘Run as administrator’). Currports is safe and won’t install any junk on your PC – in fact, it’s a portable program, so you don’t need to install anything on your computer at all.
