Keyloggers are sneaky little programs that can record everything you type, including usernames, passwords, credit card numbers, and other sensitive information. Although antivirus software is often able to detect and eliminate such programs once you’re infected, they’re not foolproof. KeyScrambler Personal promises to encrypt your keystrokes at the level of your keyboard driver and decrypt them when they reach your browser so they’re visible to you. Sounds good in theory, but does it work? We can’t guarantee that it’s perfect, but we can say that it worked just fine when we tried it.
