I have a virus that blocks and unables the CD drive -How to delete it?

I know that most of you will say : format from zero. I have a PI 133mhz machine with 12x cd drive. I know, quite old. The thing is that it doens´t want to open the CD door and if it does by the mechanical option, it won´t acces it through win95a OS. I know I have a virus. I deleted the CD drive, restored it, put the drivers on....everything goes fine after reebooting.

When I shut it down, and turn it on after exactly 15 minutes, the CD is gone, and cannot acess it anymore.
