What are the most dangerous computer viruses?
Most Dangerous Computer Viruses
Computer viruses are malicious software programs that replicate themselves and spread from one computer to another. When a virus infects a computer, it can corrupt or delete data, inflict damage on the system, and even steal personal information. Some viruses are designed to cause more harm than others, and these are typically the ones that are considered the most dangerous.
Here are some of the most dangerous computer viruses that have been released over the years:

The rise of dangerous computer viruses
With the rapid development of computer technology, the number and types of computer viruses have increased rapidly. A virus is a malicious code or program that self-replicates by infecting other computer programs and files. Once a computer is infected, the virus can spread to other computers connected to the same network. The most common way for a virus to spread is by email attachments or by downloading infected files from the internet.
The first viral infection on a computer was the Creeper virus, which was created in the early 1970s. The Creeper virus would display the message “I’m the creeper, catch me if you can!” on the infected computer’s screen. The Creeper virus would then copy itself to any other connected computers.
In the 1980s, computer viruses became more sophisticated and destructive. The Elk Cloner virus, which infected Apple II computers, was one of the first viruses that could spread itself without any user interaction. The virus would infect a computer’s boot sector, which is the part of the computer’s memory that contains the code that starts up the computer. When an infected computer was turned on, the Elk Cloner virus would copy itself to any floppy disks that were inserted into the computer. Once a floppy disk was infected, the virus would spread to any other computer that used that disk.
In 1982, the first IBM PC virus, known as Brain, was created. Brain would infect the boot sector of an infected computer and add the text “Welcome to the Dungeon” to the beginning of any infected files. Brain was created by two Pakistani brothers, Basit Farooq Alvi and Amjad Farooq Alvi, who used it to infect the computers of their competitors.
In 1986, the first Mac virus, known as nVIR, was created. nVIR would infect the boot sector of an infected computer and add the text “Welcome to the Dungeon” to the beginning of any infected files. nVIR was created by an unknown person.
In the 1990s, computer viruses became more widespread and destructive. The Michelangelo virus, which was first released in 1992, was a destructive virus that infected the boot sector of an infected computer. The virus would activate on March 6, the birthday of the Italian artist Michelangelo, and would encrypt all of the files on the infected computer’s hard drive. The virus would then display a message that said “Your computer has been infected by the Michelangelo virus. If you see this message, your data is safe. If you don’t see this message, your data is probably destroyed.” The Michelangelo virus caused over $5 million in damage and was one of the most destructive viruses of the 1990s.
In 1999, the Melissa virus was released. Melissa was a destructive virus that infected Microsoft Word documents. The virus would spread itself by emailing itself to the first 50 addresses in the victim’s address book. The virus would then infect any Word documents that were opened on the infected computer. The Melissa virus caused over $80 million in damage and was one of the most destructive viruses of the 1990s.
In the 2000s, computer viruses became more sophisticated and destructive. The ILOVEYOU virus was released in 2000. The ILOVEYOU virus was a destructive virus that spread itself by emailing itself to the victim’s entire address book. The virus would then infect any files that were opened on the infected computer. The ILOVEYOU virus caused over $10 billion in damage and was one of the most destructive viruses of the 2000s.
In 2001, the Code Red virus was released. The Code Red virus was a destructive virus that spread itself by infecting web servers. The virus would then infect any computers that accessed the infected web server. The Code Red virus caused over $2 billion in damage and was one of the most destructive viruses of the 2000s.
In 2004, the Mydoom virus was released. The Mydoom virus was a destructive virus that spread itself by emailing itself to the victim’s entire address book. The virus would then infect any files that were opened on the infected computer. The Mydoom virus caused over $50 billion in damage and was one of the most destructive viruses of the 2000s.
In 2007, the Storm Worm virus was released. The Storm Worm virus was a destructive virus that spread itself by emailing itself to the victim’s entire address book. The virus would then infect any files that were opened on the infected computer. The Storm Worm virus caused over $80 billion in damage and was one of the most destructive viruses of the 2000s.
