Add Windows' built-in password protection, and yes, you've got some basic security. Another simple but effective safeguard is Desktop-Lok , which displays a phony desktop that makes it look like your PC isn't locked. You can customize the background color and wallpaper of this dummy desktop to mirror your own settings, and snoops won't suspect a thing. So now you're all set. Unless you share a computer with others.
Encryption is the answer.
And encryption does not get much easier than Kremlin . With this straightforward privacy tool, you simply drag and drop the files you want to encrypt. Decryption is just as easy. Also, Kremlin can wipe all traces of sensitive data from the computer by securely shredding the files you delete. If you want to share encrypted files with other users, try SecurPC .
