I can fix a boot sector virus in 98 very easily. I'd seek other fix-it articles. For me, I make a virus free boot diskette (run win98se.exe from bootdisk.com) on a virus free machine, then boot that write protected diskette and type...

FDISK /MBR

The boot sector virus is now removed. BUT if it's in the OS or elsewhere, you still need to deal with that.
