Hi We just discussed using dd on a mbr. writing to 512 bytes destroys the partition table as well as the MBR. Kerry suggests 446. But this would make your MS OS unbootable. From memory of your question. If you install a linux distro and putting the grub signature in the master boot record, this will overwrite any virus residing there.
