ActiveScreenLock software gives computer users a secure and reliable way to protect their computers from unauthorized access. The idea behind the software is simple but ingenious - the program simply adds a password-protected window placed on top of all the others. In order to remove it, a correct password needs to be entered. Key combinations Alt+F4, Ctrl+Alt+Del, Alt+Tab, and WinKey are blocked. ActiveScreenLock keeps a log of all invalid access attempts and wrong passwords entered. The blocking window can be activated by clicking the program's icon or after the computer is idle for a set period of time. ActiveScreenLock is also capable of hiding mouse cursor, disabling task manager, and it runs automatically if the computer is reset.
