Removing
computer viruses ranges between painfully frustrating to impossible,
and an external rescue or boot disk is frequently required to clean
viruses that are resisting removal.
In
fact, the practice of cleaning an infected device from an independent,
external, known clean device is recommended by government cyber security
departments and computer security leaders around the world.
Win8 PCs contain a new technology called Secure Boot that only boots devices that have been verified by MSFT. Many popular rescue
disks won’t boot on PCs that ship with Win8 without modification to the
BIOS (called UEFI on Windows 8 PCs) system firmware. Even MSFT’s own
Windows Defender Offline won’t boot.
PC
manufacturers must include a technology called Secure Boot in order to
ship PCs with Win8. Secure Boot uses a public-key infrastructure to
verify the integrity of the operating system and prevent unauthorized
programs such as bootkits from infecting the device. One consequence of
Secure Boot is bootable removable media (rescue disks, Live CDs, Live
USBs) will no longer work on PCs that ship with Win8 unless they’re
upgraded to include the necessary signed components. So far it looks
like only FixMeStick has upgraded.
We’ll
keep you up to date as more rescue disks support this new Secure Boot
architecture and please let us know if you know of any that do already.
