Most banks in Europe offer a new service on their internet pages. When a user has to enter his login data he has the option to enter the password using a keypad that is displayed on the screen using a java applet. The user then clicks on the numbers and they appear in the password field. This is done to prevent the keylogging of the password.
The Anti-Keylogger does the same thing, only difference is, that its a tool that is started like every other windows program. After the tool is started you simply use the displayed keys to enter your passwords or other data on websites or even local programs.
