KeyScrambler Personal is a security application for your web browser that protects everything you type from key-loggers. It supports 40+ popular browsers, including Edge, IE, Firefox, and Chrome, as well as more than 200 other applications. This basically means that your activity remains private without changing the way you use your computer or restricting your online activities.
It defeats key-loggers by encrypting your keystrokes at the keyboard driver level. If a key-logger does manage to record your keystrokes, they will only be able to record the encrypted keys that are, obviously indecipherable.
As KeyScrambler Personal mostly works in the background, you will normally not notice it in operation. It does, however, have an intuitive interface that provides you with easy access to all of the application's features: When you start typing in a supported browser, you can see a banner at the top of your active window, which shows the encrypted text as you are typing. If you right-click on the tray icon, it allows you to open the Options menu. This is where you can do things like set a hotkey for turning the application on and off etc.
Overall, KeyScrambler Personal is a good tool for evading key-loggers, and it does not interfere with your daily use of other applications on your computer.
