Kiosks: The Virus Source You're Unaware Of

Here's a good point: "Public kiosks, such as those used for photo printing, are exposed to thousands of USB drives and other media every month." So it's likely that the flash drives or memory cards you plug into PC-based kiosks may infect your home or office computer.

Lifehacker offers a straightforward solution. Once your removable media has served its purpose, simply format them on a PC booted up with a Live CD. Live CDs are self-contained boot discs (usually running a variant of Linux) that let you use a computer without accessing—or installing—anything on your hard disk. Your files and operating system remain safe, as you wipe any potential threats from your potentially dirty thumb drives and camera media cards.

A personal favorite is the Ubuntu installer. While it lets you install the popular Linux variant on your computer, its trial mode is for all intents and purposes doubles as a Live CD.
