We have an Hp 8660 running win98. Recently Windows could not detect the cdrw drive. Suspecting a virus I scanned the whole system with AVG (yeah i know) and found nothing. So I booted from the recovery cd which worked fine. I formatted the hdd and recovered. At first boot the preinstalled Mcafee (very old) found the welcomB virus in memory. In windows it detects a CDROM drive which works, but not a CDRW drive, as adeptec burning software cannot find a supported cdrw drive. I cannot see how this virus survived the format and recovery or why it causes this problem as on the web it says it is harmless. Maybe the IDD ribbon is loose as the primary and secondary IDE controllers have a code 10. But then how did i recover the thing?
Probably unrelated, the machine had ram upgrades recently.
Any input would be great thx
