I have been infected by backdoor.regin, in Windows 8.1 embedded industry pro, provided by my college.
I have formatted my hard disk, with the command dd if=/dev/zero of=/dev/sda, and after that, i reflash my bios uefi (v2.3.1).
I have installed a OEM version of windows 8,provided by constructor, and create a partition for debian, but I am not sure that it is enough (because GrayFish)
Have you idea that I am not infected now ?
Sorry for the inconvenience and also expression, i do not write and speak english very well
