There is no virus by this name. However, we sometimes get queries about it from Macintosh users, since Mac OS v7.6 sometimes displays this message during boot-up.

A description of the problem distributed to Apple tech-support agents recommends that users encountering the problem start up from the Mac OS's Disk Tools floppy, find their hard disk's System folder, move the Finder and System file to the Trash, empty the Trash, rename the System folder, then restart the machine from the Mac OS 7.6 CD-ROM and use the Easy Install option to install a new copy of the OS.
