What is the most dangerous computer virus?
There are a great many computer viruses in the world, and it is hard to choose which one is the most dangerous. However, if we looked at the effects of viruses, rather than their popularity or ease of transmission, the most dangerous virus would be one that is able to disable critical systems or delete important data.
The Morris worm, released in 1988, was one of the first viruses to gain widespread attention. It was able to spread quickly and infect a large number of systems, but its real damage came from the way it overloaded servers, causing them to crash. This worm didn’t delete any data, but it was still incredibly disruptive.
The love bug, or ILOVEYOU, is a virus that first appeared in 2000. It spread quickly, emailing itself to everyone in the victim’s address book. The love bug didn’t do any serious damage, but it caused a lot of inconvenience as it filled up people’s inboxes and clogged up email servers.
The mydoom worm appeared in 2004 and is notable for being the fastest spreading virus ever. It infected millions of computers and caused a great deal of damage. The mydoom worm was used to launch denial of service attacks against major websites, and it alsosecurity flaw in Microsoft Outlook and Outlook Express to infect computers.
The WannaCry ransomware attack was one of the most serious viruses in recent years. It exploited a vulnerability in Microsoft Windows to encrypt people’s files and demand a ransom for the decryption key. The WannaCry attack affected countries all over the world, and it caused particular problems for the National Health Service in the UK where it led to the cancellation of appointments and operations.
It’s difficult to choose which of these viruses is the most dangerous, as they all caused a great deal of damage. However, if we looked at the sheer scale of the WannaCry attack, it is clear that this was the most dangerous virus of the bunch.
