ActiveScreenLock is a must have program for all those who care for the security of their computers and the data within.
    The concept of designing this program is simple yet very intelligent. It simply creates a window above all other windows locking your system from unauthorized users and disabling the keys. Hotkeys such as Alt+F4, Ctrl+Alt+Del, Alt+Tab and WinKey are disabled. The system can be reaccessed only by providing the correct password. Any other attempts to access the system including resetting it does not work as the program starts automatically when Windows starts. It is not possible to disable or delete the program from the taskbar by unauthorized users. The interface is customizable allowing you to display a computer clock or an image slideshow while the lock is on. Any attempts to break into the system are logged and displayed to the authenticated user only.
    This control utility makes it impossible to break into your system when you are away.
