Hello, I have a problem about my disk driver: My CD disk driver doesn't appear in the "my computer" window. when i noted that error, I checked in driver manager but it didn't show any error. Then i got an idea to restart the computer and the disk driver appeared for a short time and re-disappeared suddenly after 4minutes. Is that a virus? Or is that a system problem? if it is a virus, i don't why my antivirus can't find it. I use AVG 8.00. Plz help me. In case u need to know, my OS is Windows Vista Premium. My computer is HP Pavilion dv6000 and the CD disk driver is "FIJITSU MHW2120BH ATA Device".
