Free Public Wifi (not public, not free and not safe either!)

For years, I've been warning people about the nonexistant wifi network that pops up from time to time called "free public wifi".  It is the result of a bug in Windows XP where Windows automatically starts up an ad hoc network for the most recent ad hoc network it connected to.  I've seen free public wifi at airports and even at work.  Microsoft finally fixed this bug in Windows XP SP 3 but not everyone gets their MS updates.  

NPR has a nice article explaining the history, "The Zombe Network: Beware Free Public Wifi" here...
