More Win8 Bad News


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.
