Keyloggers are used in IT organizations to troubleshoot technical problems with computers and business networks. Families and businesses use keyloggers legally to monitor network usage without their users direct knowledge. However, malicious individuals can use keyloggers on public computers to steal passwords or credit card information.
To prevent this kind of attack, BestCrypt contains a special utility named Anti-keylogger. When it is activated, it prevents keyloggers from intercepting the real password that the user types.
Anti-keylogger can be enabled/disabled in Control Panel-->Options-->Anti-keylogger settings menu:

When Anti-keylogger is disabled, any utility, that can capture input from your keyboard, can see exactly what you type in. 

Below you can see how keylogger can capture a password.

If you decide to activate anti-keylogger, all your input will be shown as randomly generated.

When  Anti-keylogger on, it is visible, as small red underline appear.

The Anti-keylogger was successfully tested with many existing keyloggers.

So it is recommended to have it enabled, if you want to ensure your safety.
