The history of the world’s most dangerous computer virus

In the early days of computing, viruses were commonly spread by people exchanging software on floppy disks. As the internet became more popular, viruses began to spread online, often attached to email messages or hiding in websites. Some of the most famous viruses in history have caused billions of dollars in damage and caused havoc for businesses and consumers alike.

The first known computer virus was created in the 1970s by a Pakistani computer scientist named Dr. Farooq Alvi. His virus, which he called the “creeper,” was designed to delete files and spread itself to other computers. The creeper was not particularly harmful, but it was the first virus to be seen in the wild.

In the 1980s, another virus called the “Elk Cloner” became the first to infect Apple computers. This virus was spread by people sharing floppy disks and was designed to display a message on the victim’s screen that read “Elk Cloner: The program with a personality.”

The late 1980s and early 1990s saw the rise of the first mass-mailing viruses, which were able to spread quickly by sending themselves to everyone in the victim’s address book. One of the most famous of these viruses was the “Melissa” virus, which caused more than $80 million in damage when it was released in 1999.

The early 2000s saw the rise of viruses that were designed to steal personal information, such as credit card numbers and passwords. These so-called “Trojan horses” became increasingly common as online banking and shopping became more popular.

One of the most damaging viruses in history was released in 2010. Called “Stuxnet,” this virus was specifically designed to sabotage Iranian nuclear facilities. The virus proved so effective that it is believed to have set back Iran’s nuclear program by several years.

Today, viruses are more common than ever. Most are designed to steal personal information or to hold computer systems hostage until a ransom is paid. However, there are still some viruses that are designed simply for the sake of causing damage. As long as there are computers in the world, there will be viruses.
