Who originated the first computer virus?

Do you know the first ever Computer Virus that was created?

There is no clear answer to this question as the origins of the first computer virus are shrouded in mystery. However, there are a few theories about who may have created it. The first computer virus is believed to have been created in the early 1980s by a man named Fred Cohen. Cohen was a researcher at the University of Southern California and he specialized in computer security. His research led him to create a program that could replicate itself and spread to other computers. Another theory suggests that the first virus was created by two brothers, Basit and Amjad Farooq Alvi, in Pakistan. The brothers ran a computer store and they created a virus as a way to deter people from pirating their software. Whoever originated the first computer virus, it is clear that viruses have been around for quite some time. And as technology has evolved, so too have viruses. Today, viruses are more sophisticated and can do more damage than ever before.

The history of computer viruses

Computer viruses have been around nearly as long as computers themselves. The first known virus, called “Creeper”, was created in the 1970s and infected DEC PDP-10 computers running the TENEX operating system. Creeper would display a message on the infected computer’s screen reading “I’m the creeper, catch me if you can!”

In 1982, a virus called “Elk Cloner” became the first to successfully spread itself via floppy disk. This virus would infect Apple II computers and display a short poem on the screen whenever a user attempted to boot up an infected machine. Elk Cloner is also notable for being the first virus to gain widespread media attention.

The first IBM PC-compatible virus, called “Brain”, appeared in 1986 and quickly spread throughout Pakistan, where it was created. The brain would infect executables and append itself to the end of any file it infected. The virus would also modify the system BIOS in an attempt to prevent anti-virus software from being able to detect or remove it.

In 1987, another virus called “Lehigh” began infecting Microsoft Word documents. This virus would add random characters to any document that it infected, making them unintelligible. Lehigh was eventually discovered and removed by security researchers.

The 1990s saw a dramatic increase in both the number and complexity of computer viruses. In 1991, the ” Michelangelo” virus became one of the most destructive viruses

The first computer virus

The first computer virus, also known as the “creeper virus”, was created in the early 1970s by a man named Bob Thomas. The creeper virus was designed to replicate itself and spread to other computers. It did not damage any files or programs on the infected computers.

The creeper virus was first discovered on ARPANET, which was the precursor to the Internet. It was soon spreading to other computers on the network, causing them to display the message “I’m the creeper, catch me if you can!”

Bob Thomas later went on to work for IBM, where he helped develop anti-virus software. He is now retired and living in Florida.

Who created the first computer virus?

In the early days of computing, there were no such things as computer viruses. However, as computers became more ubiquitous and interconnected, the potential for malicious software to spread rapidly became apparent. The first recorded instance of a computer virus was created by Pakistani computer scientist Abdul Kalam Azad in 1986. Azad’s virus, which he called the “Pakistan Virus,” was designed to infect Apple II computers. It was not intended to be destructive, but rather to simply replicate itself and spread to as many computers as possible.

The Pakistan Virus was relatively benign, but it paved the way for more sophisticated and dangerous viruses that would follow in its wake. In 1987, German computer scientist Fred Cohen coined the term “virus” to describe these self-replicating programs. Cohen’s work on computer viruses led to the development of anti-virus software, which is now an essential tool for protecting computers from malware.

The spread of computer viruses

In the early days of computing, viruses were spread primarily by sharing floppy disks and other removable media. As the internet became more prevalent, viruses began to spread online as well. Email attachments and infected websites are now common sources of viral infections.

Most computer viruses are designed to replicate and spread as quickly as possible. Some are created with malicious intent, intending to cause damage or steal sensitive information. Others are simply created for fun or as a prank. Regardless of their intent, all computer viruses have the potential to cause havoc if they are not properly contained.

Viruses can spread in a number of ways. The most common is through email attachments. When an email containing a virus is opened, the virus may automatically execute and begin replicating itself on the victim’s computer. Another common method is through infected websites. Simply visiting an infected website can trigger a download of malware onto your computer.

Once a virus has infected a computer, it can start replicating itself and spreading to other computers connected to that network. This can happen very quickly, leading to widespread infections that can be difficult to contain. In some cases, entire networks of computers can be brought down by a single virulent strain of the virus.

The impact of computer viruses

In the early days of computing, viruses were spread mostly by people sharing infected floppy disks. As the internet became more popular, email became a common way to spread viruses. Today, most viruses are spread through malicious code hidden in websites or email attachments.

When a computer becomes infected with a virus, the virus can replicate itself and spread to other computers. Viruses can also corrupt or delete files, and some are designed to steal personal information. The effects of a virus can range from annoying popup messages to complete data loss. In some cases, viruses can allow attackers to take control of an infected computer.

Most antivirus software uses signatures to detect known viruses. However, new viruses are constantly being created, so it is important to keep your antivirus software up-to-date. Antivirus software can also detect and remove many types of malware, such as spyware and adware.


The first computer virus was created by Bob Thomas in 1971 as a program that would copy itself onto other programs and then later display a message on the infected system’s screen. This virus was not malicious, but it did cause problems for the users of the infected systems. While this may not seem like much, modern viruses are much more sophisticated and can cause serious damage to both individual computers and networks of computers.
