Just to let you all know. I was getting the same problem.
Nothing could burn - Nero, CD BurnXP, etc
Ran AVG Rootkit, it found 2 hidden driver files and renamed them on reboot.
Ran Malwarebytes' Anti-Malware 1.38 and it found 26 infect files associated to the SKYNET Trojan.
Every program burns now, no problems.
Thank god ImgBurn actually has a useful console or I never would have known why my drive was not being seen
