Title: Method of ensuring that the PC is not used to make unauthorized and surreptitious telephone calls

Abstract: The present invention prevents unauthorized access and modifications to programs and non-executable files, particularly a dialer program, stored on a personal computer system (PC) by providing a protected storage area on a hard drive of the PC wherein access to the protected storage area is controlled by the owner/user of the PC. Attempts to add, remove, or modify any of the programs and non-executable files in the protected storage area will result in an interrupt prompting the user to supply a valid password or other acknowledgement. A preferred embodiment includes a protected memory area as a part of the computer's internal random access memory (RAM) such that upon initialization of a program, the program and non-executable files are copied into the protected memory area from the protected storage area. The protected memory area may also be password protected to provide additional safeguards against unauthorized access. Also disclosed is a method and apparatus for creating and utilizing a program storage table and a program function table for controlling access and modifications of programs and non-executable files, particularly a dialer program, stored in the protected storage area. Preferably, the present invention may be embodied as a computer program product stored on a program storage device.
