The history of the world’s most dangerous computer virus

In the early days of personal computing, viruses were spread mostly via floppy disks. As email became more popular, virus authors found new ways to spread their creations: by infecting attachments and sending them to contacts in address books. More sophisticated viruses appeared that could infect both executable files and documents. These new types of viruses posed a serious threat to businesses and individual users alike.

The world’s first known computer virus, called Elk Cloner, appeared in 1982. It was created by a high school student in the United States and spread via floppy disks. When a computer infected with Elk Cloner booted up, the virus would display a short poem on the screen. The poem ended with the line, “It will get on all your disks; it will infect your whole system. Beware!”

Elk Cloner was a relatively harmless virus, but it demonstrated how a virus could Spread quickly and easily. Just a few years later, in 1986, the first PC virus capable of infecting both executable files and documents was created. This virus, called Brain, originated in Pakistan. Brain quickly spread around the world, causing significant financial damage to businesses and individuals.

The damage caused by Brain inspired virus authors to create even more destructive viruses. In 1988, the first virus specifically designed to damage hard drives was released. This virus, called Stoned, was created in the Netherlands. It quickly spread to computer systems around the world, causing data loss and corruption.

The 1990s saw the rise of a new type of virus: the macro virus. These viruses infected documents, rather than executable files. The first macro virus, called Concept, appeared in July 1995. It spread quickly, infecting over one million documents within a few months.

The spread of macro viruses was facilitated by the popularity of Microsoft Office. Macro viruses could easily infect documents created in Word, Excel, and PowerPoint. As a result, macro viruses became a serious threat to businesses. In some cases, businesses were forced to shut down their email systems to prevent the spread of macro viruses.

The early 2000s saw the rise of another new type of virus: the worms. Unlike previous viruses, which required human interaction to spread, worms could spread automatically, without any action on the part of the user. The first worm, called Code Red, appeared in 2001. It spread quickly, infecting over 300,000 computers within a few days.

The Code Red worm was followed by a number of other, equally destructive worms. In 2003, the Blaster worm appeared. Blaster infected over 10 million computers within a few days. In 2004, the Sasser worm caused widespread disruption, infecting over 1 million computers.

The spread of worms was facilitated by the increasing popularity of broadband Internet connections. Worms could spread quickly and easily over high-speed Internet connections. As a result, they posed a serious threat to businesses and individual users alike.

In the early 2010s, a new type of virus appeared: the ransomware. Ransomware is a type of virus that encrypts the files on a victim’s computer and demands a ransom to decrypt them. The first ransomware, called CryptoLocker, appeared in 2013. It spread quickly, infecting over 250,000 computers within a few months.

Ransomware quickly became a serious threat to businesses and individuals. In some cases, ransomware victims were forced to pay tens of thousands of dollars to decrypt their files. In 2015, a ransomware called Cryptowall appeared. It was even more destructive than CryptoLocker, infecting over 600,000 computers within a few months.

Today, ransomware is one of the most serious threats to businesses and individuals. Ransomware authors are constantly evolving their viruses, making them more difficult to detect and decode. As a result, ransomware is a growing problem for businesses and individuals alike..Click for source

How do computer viruses work?

A computer virus is a type of malicious code or program that, when executed, replicates by inserting itself into other computer programs, data files, or the boot sector of the hard drive. When this insertion or replication occurs, the affected areas of the computer are typically corrupted or otherwise malfunctioning.

Viruses are typically spread by email attachments, infected websites, or by sharing infected files with other users. Once a virus has been introduced to a computer, it can spread rapidly by automatically replicating itself and sending itself out to everyone in the user’s address book. This rapid propagation can result in a computer being quickly overwhelmed by the virus, causing it to crash or become severely sluggish.

Viruses can also be spread by USB flash drives, external hard drives, or other removable media. When these devices are used on an infected computer, the virus can be copied onto them and then spread to other computers when the devices are connected to them.

Most viruses are harmless and only cause annoying symptoms like pop-up messages or slowed performance. However, some viruses can be much more destructive, deleti
