You can remove it, the simple answer is to rebuild MBR, do everything BUT DONT BOOT INTO MAIN WINDOWS and then you format the C: drive to make the hard drive have no data, after that install windows, you will be greeted with a CLEAN OS, oh, it removed the bios? update to malware so it removes bios? well it is FINE just use the backup bios- wait you dont have any other? do bios recovery and you sould be able to boot the computer and then you could just chill again.
