Abstract
A method is disclosed for securing an existing executable software program against infection or corruption by software viruses or the like, without requiring any modification to the program's source code or any recompilation or relinking. Security routines capable of detecting the presence of any virus infection or other corruption are coupled to the program. The loading information for the program is modified so that upon any attempt to execute the program, the security routines will execute first and scan for viruses or other corruption. If any viruses or corruption are detected, execution of the program is aborted and a warning is displayed. If no viruses or corruption are found, the security routines are removed from memory and execution of the program continues normally.
