A boot sector virus is believeable. Cross contamination my portable media with zero write protection has been an exploitable bug in the system.
In the old days of floppies, my service disks were write protected. In the days of CD's they were write protected by default. Since CF cards and beyond, Write protection is off by default and most often missing entirely.
Service software is now held on CD ROM on a USB drive. Anyone using writable software to service machines is a fool.
The author admits to using non write protected media to "Flash" his BIOS.
He needs to pratice safe computing in an infected environment if he is to get any chance of recovery. A known clean machine with known clean write protectable media such as a burned CD or DVD is the only way to clean up an infected machine with BIOS, Boot Sector, or other nasty infection.
Does the author know about write protected media and computer service to prevent spreading infections?
