Hyper-Threading (ALL)
Select Enable to use Intel Hyper-Threading Technology to enhance CPU performance. The
options are
Enable
and Disable.
Execute Disable Bit (Available if supported by the OS & the CPU)

it cannot, thus preventing a worm or a virus from flooding illegal codes to overwhelm the
processor, damaging the system during a virus attack. The options are
