The Michelangelo virus is a computer virus first discovered in April 1991 in New Zealand.[1] The virus was designed to infect DOS systems (but did not engage the operating system or make any OS calls; Michelangelo, like all boot sector viruses, basically operated at the BIOS level) and remained dormant until March 6, the birthday of Renaissance artist Michelangelo. There is no reference to the artist in the virus, and it is doubtful that the virus writer intended Michelangelo to be referenced to the virus. Michelangelo is a variant of the already endemic Stoned virus.

On March 6, if the PC is an AT or a PS/2, the virus overwrites the first one hundred sectors of the hard disk with nulls. The virus assumes a geometry of 256 cylinders, 4 heads, 17 sectors per track. Although all the user's data would still be on the hard disk, it would be irretrievable for the average user.

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.

  • This is the last directory of the 1.2 MB disks.
  • This is the second-to-last directory of the 1.44 MB disks.
  • The directory does not exist on 720 KB disks.

Although designed to infect DOS systems, the virus can easily disrupt other operating systems installed on the system since, like many viruses, the Michelangelo infects the master boot record of ahard drive. Once a system became infected, any floppy disk inserted into the system (and written to; in 1992 a PC system could not detect that a floppy had been inserted, so the virus could not infect the floppy until some access to the disk is made) becomes immediately infected as well. And because the virus spends most of its time dormant, activating only on March 6, it is conceivable that an infected computer could go for years without detection - as long as it wasn't booted on that date after being infected.

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'sLANSpool print server, infected with the virus. Although the infected machines numbered only in the hundreds, 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.

It was a "boot-sector virus", which means it didn't use the file system but instead wrote directly to the storage device.

What is cryptogram of virus?

Do you mean "what is a cryptogram virus?". If the answer is yes, then i have your solution. Cryptogram viruses are very dangerous viruses that infect your computer and then encrypt it, so that nothing, not even the Operating System, can read your computer except for the virus. Cryptogram viruses count as ransomware, which is a type of malware that after infection, the creator of the virus demands that you pay them a rather large sum of money in order to unlock your computer from the virus' grip. If you don't pay them the money, they will hack your computer regardless and basically rob you of everything if they are that skilled. Generally, they are not. Just be careful of what your download off the Internet (Rule #1 to keeping your computer virus free).
