From Password Security Technology:
Password Protector is an intelligent real-time password protection software. It can help you keep your password from being stolen by spywares and trojans. It is different from traditional anti-spyware tools and trojan removers. Instead of searching for spywares and trojans by matching the definition database of them, Password Protector is based on action detecting system. When a spyware or a trojan is attempting to steal your password, credit card number or some other privacy information, Password Protector can detect the action and inform you to react in time. Thus, even the newest spywares, trojans or unknown variations of them can steal nothing from your computer. Under the protection of Password Protector, you will feel extra safe when you enter password on your computer.
