 Boot sector viruses are a type of malware that infects the boot sector of a storage device, such as a hard drive or floppy disk. Here’s a list of some well-known boot sector viruses:

1. **Brain** (1986) - The first known boot sector virus, originating from Pakistan.

2. **Stoned** (1987) - A very common boot sector virus, with many variants.

3. **Michelangelo** (1991) - A famous boot sector virus known for its destructive payload that activated on Michelangelo's birthday (March 6).

4. **Disk Killer** (1989) - A boot sector virus that displayed a warning message before causing damage.

5. **Parity Boot** (1993) - A boot sector virus that caused various system malfunctions.

6. **AntiEXE** (1994) - A boot sector virus designed to infect computers running DOS.

7. **Form** (1990) - A boot sector virus that caused occasional beeps when keys were pressed.

8. **Stone Empire Monkey** (1991) - A stealth boot sector virus that was difficult to detect.

9. **NYB** (1994) - Also known as "B1," a common boot sector virus.

10. **Empire Monkey** (1992) - A complex virus known for its stealth capabilities.

These viruses were particularly common in the 1980s and 1990s when floppy disks were widely used for booting systems. Modern antivirus software can generally detect and remove these older viruses, but they are less common in the era of more advanced malware.

Here are additional boot sector viruses that were known to be prevalent, particularly in the era of floppy disks and early hard drives:

11. **Marijuana** (1991) - A boot sector virus known for displaying a message referencing marijuana.

12. **Tequila** (1991) - A polymorphic boot sector virus that was difficult to detect due to its constantly changing code.

13. **Ripper** (1994) - A boot sector virus that corrupted data on hard drives and floppy disks.

14. **Taiwan** (1991) - A boot sector virus that spread through infected floppy disks, causing system errors and crashes.

15. **NoInt** (1990) - A boot sector virus that infected both floppy disks and hard drives, causing random system crashes.

16. **Stealth Boot** (1992) - A boot sector virus that was designed to be hidden from detection by antivirus software.

17. **Junkie** (1991) - A boot sector virus that spread rapidly, causing boot failures and data loss.

18. **Michelangelo.A** (1992) - A variant of the Michelangelo virus, known for causing data destruction on March 6th.

19. **XPEH** (1994) - A boot sector virus that targeted the Master Boot Record (MBR), often causing system instability.

20. **Da'BOOM** (1995) - A boot sector virus that displayed a message before corrupting the file system.

These viruses primarily affected older operating systems like DOS and early versions of Windows, where booting from floppy disks was common. Modern systems are less vulnerable to these types of viruses due to advancements in security and changes in how operating systems handle boot processes.

Here’s an additional list of boot sector viruses that were known in the past:

21. **Polyboot.B** (1993) - A polymorphic boot sector virus that changed its code to avoid detection.

22. **AntiCMOS** (1994) - A boot sector virus that specifically targeted the CMOS settings of infected computers, causing hardware configuration issues.

23. **SatanBug** (1994) - A boot sector virus that infected both floppy disks and hard drives, leading to data loss and system crashes.

24. **Exebug** (1992) - A stealthy boot sector virus that infected the MBR, making it difficult to detect by early antivirus programs.

25. **Quox** (1990) - A boot sector virus that infected floppy disks, causing data corruption and system instability.

26. **Natas** (1992) - A complex virus that infected both the boot sector and executable files, making it particularly challenging to remove.

27. **Die_Hard** (1993) - A boot sector virus known for its destructive payload that could wipe out critical system files.

28. **Azusa** (1990) - A boot sector virus that infected floppy disks and caused various system errors.

29. **Green Caterpillar** (1993) - A boot sector virus that displayed a graphic of a green caterpillar before damaging the infected system.

30. **Goldbug** (1990) - A boot sector virus that displayed a message in German and caused system corruption.

These viruses were often spread through infected floppy disks, which were commonly used for transferring files and booting up systems. While boot sector viruses are largely a relic of the past, they played a significant role in the history of computer security, leading to the development of more advanced antivirus software and protective measures.
