Passwords that you type in Windows can be intercepted by keylogger programs. Keyloggers are used in IT organizations to troubleshoot technical problems with computers and business networks. Families and business people 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 called Anti-Keylogger. When Anti-Keylogger is active, keyloggers get random keystrokes instead of a real password. Even if your password is "aaaaaa", it will be intercepted and replaced with a random string. Every time you enter the same "aaaaaa" password, the intercepted string will be different.
