This article on the spread of malware via USB drives caught my attention because I encountered this problem last year. I would think this would be a big issue in education at all levels. Students carry content on USB drives so they can use computers in multiple labs (and at home). I am not a big Windows user, but the classrooms in which I teach offer the Windows operating system for instructors. I prepare content on a Mac and present using Windows. This switching experience offers some interesting insights. When I bring the USB drive back to my Mac, I can see files that were not there when I took the drive to class. The instructors are sharing a machine and also malware.
