Nothing beats a USB port for convenience, whether you want to quickly transport a couple gigabytes of files for work, refresh the lineup on your MP3 player, or view the pictures from your recent trip to Boise. Unfortunately, USB ports also provide an overly convenient bridge for malware to creep from a portable media device onto an unsuspecting user's system. In fact, it seems nearly every client I visit these days has numerous computers carrying USB-infecting malware -- even trusted clients with otherwise stellar security histories. It's getting so bad that I'm scared to share USB keys with my clients.
