In the last couple of weeks, work implemented a 'USB Flash Drive Encryption' program. Every time you pop a flash drive on any machine on the network, it automatically tries to encrypt all files on the flash drive. It pops up this nice little window where you have to go through and deselect certain boxes before you can successfully cancel without all the files becoming encrypted, if you don't have the right ones deselected, it starts over. Major pain, especially since it installs the decryption program in some obscure location on the flash drive that you have to hunt for before you can use any files on the drive if you didn't cancel it in time (unless you are on the major network at work).
It is especially fun when vendors bring their flash drives in with their sales pitches. Good times!
