In early 2014, a several year old installation of Smilebox began showing a black postage stamp sized “window” in the upper left corner of the monitor. The square was eliminated by stopping the SmileBoxTray.exe using the Windows Task Manager. The black window reappeared after the Smilebox application was used. The black window did not seem to have any overt action associated with it but its properties showed LSOs from a number of websites. It isn’t clear if the SmileBoxTray was actually collecting the LSO information itself or if it just had access to LSOs collected by other applications that also used Adobe Flash. SmileBoxTray clearly seems to be spyware making use of the capabilities of Adobe Flash. 3/3/14
