What is NetStumbler?

NetStumbler is a tool for Windows that allows you to detect Wireless Local Area Networks (WLANs) using 802.11b, 802.11a and 802.11g. It has many uses:Verify that your network is set up the way you intended, find locations with poor coverage in your WLAN, detect other networks that might be causing interference with your network, detect unauthorized "rogue" access points in your workplace, help aim directional antennas for long-haul WLAN links & use it recreationally for WarDriving. Does not work well with Win7. This software has not been updated in years and harkens back to Win Vista days.

Just tried downloading and installing Network Stumbler. It came with a large set of malware downloads including a downloader active agent. Seems like it was pretending to be a zip opener. No permission was asked, and no options were presented to opt-out of the extra crudware.

In any case, cleanup required uninstalling at least three programs, running a Windows System restore to a previous date, and then running MalwareBytes, in order to completely remove all traces of malware.

This was an experience of the worst kind of misleading BS crapware.
