A problem with the Bitfender virus scanner mislabeled Windows system files as viruses and quarantined them.  Therefore, without these files being available during the boot process, the computers fail to boot.  This only seems to affect 64bit versions of Windows and they have made a patch available, which should be installed as soon as possible to avoid this issue.  Information on how to get around the boot problem can be found on their website also.
