Information about Michelangelo (computer Virus)
The Michelangelo virus is a computer virus first discovered in April 1991 in New Zealand.[1] The virus was designed to infect MS-DOS systems and remain dormant until March 6, the birthday of Renaissance artist Michelangelo.
On March 6, if the PC is an AT or a PS/2, the virus overwrites the hard disk with nulls. The virus assumes a geometry of 256 cylinders, 4 heads, 17 sectors per track.
On hard disks, the virus moves the original master boot record to cylinder 0, head 0, sector 7.
On floppy disks, if the disk is 360 KB, the virus moves the original boot sector to cylinder 0, head 1, sector 3.
On other disks, the virus moves the original boot sector to cylinder 0, head 1, sector 14.
The virus first came to widespread international attention in January 1992, when it was revealed that a few computer and software manufacturers had accidentally shipped products, for example Intel's LANSpool print server, infected with the virus. Although the infected machines numbered only in the hundreds,[2] the resulting publicity spiraled into "expert" claims of thousands or even millions of computers infected by Michelangelo. However, on March 6, 1992, only 10,000 to 20,000 cases of data loss were reported. The news media lost interest, and the virus was quickly forgotten. Despite the scenario given above, in which an infected computer could evade detection for years, by 1997 no cases were being reported in the wild.[3]

A computer virus is a computer program that can copy itself and infect a computer without permission or knowledge of the user. The original virus may modify the copies, or the copies may modify themselves, as occurs in a metamorphic virus.
