1. A computer system for securing computer files from modification comprising:

  • a processor;

    a first internal data storage area;

    a non-volatile second internal data storage area physically separate from the first data storage area, the second data storage area having stored thereon files that are executable by the processor, including executable files of an operating system configured to save temporary files on the first data storage area; and

    a control circuit operatively coupling the first internal data storage area and the second internal data storage area to the processor, wherein the control circuit is configured to operate in a first mode to allow communication from the processor to the first internal data storage area of all commands received from the processor, to block communication to the second internal data storage area of commands that are configured to modify the second internal data storage area, and to allow communication to the second internal data storage area of commands received from the processor that are configured not to modify the second internal data storage area, and to operate in a second mode to allow communication from the processor to the first and second internal data storage areas of all commands received from the processor.
