KeyScrambler, a web browser plugin, encrypts your keystrokes to protect your important personal information from keyloggers.

How Keyloggers Work

When you type on your keyboard, the keys travel along a path within the operating system before it arrives at your browser. Keyloggers plant themselves along this path and observe and record your keystrokes. The collected information is then sent to the criminals who will use it to steal from you.
How KeyScrambler Protects You

KeyScrambler defeats keyloggers by encrypting your keystrokes at the keyboard driver level, deep within the operating system. When the encrypted keystrokes reach your browser, KeyScrambler then decrypts them so you see exactly the keys you've typed. Keyloggers can only record the encrypted keys, which are completely indecipherable.

Unlike anti-virus and anti-spyware programs that depend on recognition to remove keyloggers that they know about, KeyScrambler will protect you from both known and unknown keyloggers.
