PortDetector tells you if you are being monitored or your files viewed remotely. Currently (as shown above) you may choose any port to monitor (defaults for basic services are shown.) This is particularly useful if you are in a public wifi spot and want to take extra precautions to stay safe.

Tried downloading from both this website and the developer's. Upon unstuffing (unzip), Stuffit returned this error:
"An error occurred attempting to expand 'PortDetector2Trial.zip'. The archived may be damaged. Error 17537"

The only result of the expanded zipfile was an empty folder titled, "PortDetector2.0Trial"

Recommend the developer download it and attempt to expand it himself.

Why didn't the beta testers notice this?
