Abstract
A system and method for preventing a program from being run under a debugger utility program. The method is part of a routine which is stored along with a software program on a hard drive of a computer system. The computer system has a processor for running both the software program and the routine and is capable of operating in a debug mode. The routine prevents unauthorized access to the software program, such as when the processor is running in the debug mode. When the processor is running the software program, the program can initiate execution of the routine. Once initiated, the routine checks a certain registers of the processor to determine if it is operating in the debug mode and if so, stops the processor from continuing to run the software program.
