As for the driver for Virtual Disk Bus Enumerator - I assumed that this was the Comodo vdbus.sys driver rthat I had renamed earlier. I renamed it back to the original name, and then via the Device Manager uninstalled it. Then I scanned for new hardware, and the device did not re-appear. I then rebooted, and the device did not appear in the Device Manager. I am not going to worry, as I do not use Comodo Backup anymore.
As for corruption on my C: drive - I have seen cases in the past where the drive was corrupted, and I could not determine why. On my C: drive I have 10 found.nnnn directories from previous disk corruptions and subsequent "chkdsk c: /f" executions. I ran a chkcsk c: before I rebooted, and there were no errors reported.

In most cases, I cannot tell from the recovered files what directory was corrupted. There have been times when I have experienced a BSOD, and, upon reboot, Windows 7 Pro automatically ran a chkdsk c:: command.
