SoftPerfect WiFi Guard is an application for Windows that scans your network and displays a list of all the connected computers. It pings all devices connected to the network and shows everything that returns a ping. Moreover, if an unknown device connects to the network, you are immediately alerted through a notification on your screen. When you run the app for the first time, the Settings dialog box pops up. It lets you select the default Network Adapter, choose the Scanning Options and specify the UI behavior. The application allows you to scan up to 32 devices simultaneously and enable the network to be rescanned periodically. You can specify a range from 1 – 60 minutes the rescan interval.
