We have a PC with firmware malware on - at least - both DVDs.
Ugh, sorry, not sure I've got answers that might be useful for you. So.... we have *trustworthy* computing at work once again. The infection could be at the BIOS level of the PC, it could be that somehow the DVD drive's firmware has been infected -- how would you really know? DVD drives are very, very cheap these days. It could be bad USB playing games; if that is the case, then perhaps USB sticks and drives also have problems (potentially). Are the DVD drives connected via USB or SATA? It would have to be an old system if XP might be part of the problem and even older if you are using IDE drives (optical or other).
I don't know if it's worth recovering the system, but I definitely want to find diagnostics for identifying infections and vectors on the rest of the LAN.
The trouble may be that at some time in the future, it will be very hard to get motherboards that are free and open enough to rely upon. What about the possibility of installing a different motherboard firmware? Perhaps core-boot? I don't know. If the equipment is too old, then doing anything much will likely be a waste and replacing with newer (if not brand new) gear might be the best way to go.
