The Friday the 13th virus, also known as the Jerusalem virus, is a type of computer malware that was first discovered in 1988. This virus was a significant threat to computer systems in the late 1980s and early 1990s, causing widespread damage and disruption. In this article, we will explore the history of the Friday the 13th virus, its impact on computer systems, and the lessons that can be learned from this malicious threat.
History of the Friday the 13th Virus
The Friday the 13th virus was first discovered on October 13, 1988, at Hebrew University in Jerusalem, Israel. The virus was named after the date of its discovery, which coincided with the supposedly unlucky Friday the 13th. The virus was initially thought to be a prank, but it quickly became clear that it was a malicious program designed to cause harm to computer systems.
The virus was written in assembly language and was designed to infect IBM-compatible computers running MS-DOS. It spread quickly through floppy disks and infected thousands of computers worldwide. The virus was particularly damaging because it was able to replicate itself and spread to other computers without the user’s knowledge or consent.
How the Virus Worked
The Friday the 13th virus worked by infecting the boot sector of a floppy disk. When an infected floppy disk was inserted into a computer, the virus would load into memory and begin to replicate itself. The virus would then infect other floppy disks that were inserted into the computer, spreading the infection to other computers.
The virus would also infect executable files on the computer, including .COM and .EXE files. When an infected file was run, the virus would load into memory and begin to replicate itself. The virus would also overwrite the contents of the infected file, causing it to become corrupted and unusable.
Symptoms of Infection
The symptoms of a Friday the 13th virus infection were varied, but they often included:
- Corrupted or missing files
- Unexplained changes to system settings
- Slow system performance
- Unusual error messages
In some cases, the virus would also display a message on the screen, including the phrase “Friday the 13th” or “Jerusalem.”

What is the Friday the 13th Virus?
The Friday the 13th Virus is a type of computer malware that was first discovered in the early days of personal computing. It is a boot sector virus, which means it infects the boot sector of a computer’s hard drive, allowing it to load into memory before the operating system. This type of virus was particularly problematic because it could spread quickly through floppy disks, which were a common method of data transfer at the time. The virus would overwrite the boot sector of a disk, replacing the normal boot code with its own malicious code.
The Friday the 13th Virus was designed to cause chaos and destruction on infected systems. When a computer infected with the virus was booted on Friday the 13th, the virus would delete all files on the hard drive, rendering the system unusable. The virus was relatively simple in design, but its impact was significant, highlighting the vulnerability of early computer systems to malware attacks. The virus also served as a wake-up call for the computer industry, leading to the development of more robust security measures and antivirus software to protect against such threats.
How does the Friday the 13th Virus spread?
The Friday the 13th Virus spreads through infected floppy disks. When an infected disk is inserted into a computer, the virus is loaded into memory, allowing it to infect the computer’s hard drive. The virus can also spread through other means, such as infected software downloads or compromised networks. In the early days of personal computing, floppy disks were a common method of data transfer, making it easy for the virus to spread from one system to another. The virus would often be transmitted unintentionally, as users would share infected disks without realizing they were carrying malicious code.
The spread of the Friday the 13th Virus was facilitated by the lack of security measures in early computer systems. Many systems did not have built-in antivirus software or other security features, making it easy for malware to infect and spread. Additionally, users were often unaware of the risks associated with sharing disks or downloading software from unknown sources, further contributing to the virus’s spread. As the computer industry evolved, security measures improved, and users became more aware of the risks, making it more difficult for viruses like Friday the 13th to spread.
What are the symptoms of the Friday the 13th Virus infection?
The symptoms of the Friday the 13th Virus infection can be subtle, making it difficult to detect the virus until it’s too late. One of the primary symptoms is the presence of unusual or unexplained errors on the system. Infected systems may experience frequent crashes, freezes, or other stability issues. In some cases, the virus may also cause strange or unexpected behavior, such as unusual disk activity or unexplained changes to system files. However, the most significant symptom of the virus is the deletion of all files on the hard drive, which occurs when the system is booted on Friday the 13th.
The symptoms of the Friday the 13th Virus infection can be similar to those of other malware or system issues, making it challenging to diagnose the problem. Users may notice that their system is running slowly or that certain files are missing, but these symptoms can be caused by a variety of factors. To confirm the presence of the virus, users would need to run a virus scan or examine the system’s boot sector for signs of infection. In the early days of personal computing, diagnosing and removing malware was a complex and time-consuming process, often requiring specialized knowledge and tools.
How can I protect my computer from the Friday the 13th Virus?
To protect your computer from the Friday the 13th Virus, it’s essential to take a multi-layered approach to security.
