The Windows 98 boot disk will enable CD-Rom support if the CD-Rom is an ATAPI drive. If it is propritory like an older Mitsumi etc. you must secure from the mfg. website and load drivers for the CD-Rom from the DOS Prompt. Some virus issues cannot be easily cleaned once the virus has spread if the virus program is loaded after the infection; even a simple virus like WIN95C111. And if you are not able to clean the drive or if the virus program keeps becoming disabled I would format and start over with a fresh install of your software.
