The invisible pirate -- information security
Strike the Root
by Joe Blow

"This edition covers file encryption, secure passwords, cleaning your computer, and a very comprehensive system utility that will keep your computer happy so that you won't lose any personal files or information. I am amazed that some people religiously change the oil in their car, but they never conduct any maintenance on their computer. Inevitably, they end up with long faces after their young children (or co-workers) delete their life's work, or post embarrassing photos of them on the web, stolen from their own hard drive. Use these methods routinely to keep you (and your computer) happy, and all of your personal information private, for free. Enjoy!" (07/27/05)
