No Execute Mode Memory Protection (Available when supported by
the CPU and the OS.)
Set to Enabled to enable Execute Disable Bit and allow the processor to classify

thus preventing a worm or a virus from inserting and creating a ood of codes to
overwhelm the processor or damage the system during an attack.
Note: this feature is available when your OS and your CPU support the function
of Execute Disable Bit. The options are Disabled and Enabled. Note: For more
information regarding hardware/software support for this function, please refer to
Intel's and Microsoft's web sites.
