What was the most damaging computer virus in history?
in history
The most destructive computer virus in history is known as the Mydoom worm, which was first released in early 2004. The Mydoom worm is estimated to have caused billions of dollars in damages to businesses and individuals worldwide. The Mydoom worm spreads itself by emailing itself to addresses found in the victim’s address book. Once the email is opened, the worm attaches itself to the victim’s computer and begins replicating itself. The Mydoom worm is particularly damaging because it not only replicates itself, but also deletes files and launches denial-of-service attacks against websites. The Mydoom worm is believed to be the work of a group of Russian hackers.

What is the most deadly computer virus?
of 2018 and what are the top 10 most dangerous viruses
The most deadly computer virus is the WannaCry virus. It is a ransomware virus that was released in May of 2017. It infected over 200,000 computers in 150 countries and caused over $4 billion in damages. The virus encrypts files on the infected computer and demands a ransom be paid in order to decrypt the files. The virus spread quickly due to a vulnerability in the Windows operating system that was exploited by the virus. The vulnerability has since been patched by Microsoft.
The second most deadly computer virus is the Petya virus. It is a ransomware virus that was first spotted in 2016. It uses the same exploit as the WannaCry virus to spread. It encrypted the hard drives of infected computers and demanded a ransom be paid in order to decrypt the files. The virus caused over $1 billion in damages.
The third most deadly computer virus is the NotPetya virus. It is a ransomware virus that was first spotted in June of 2017. It uses the same exploit as the Petya virus to spread. It encrypted the hard drives of infected computers and demanded a ransom be paid in order to decrypt the files. The virus caused over $10 billion in damages.
The fourth most deadly computer virus is the Locky virus. It is a ransomware virus that was first spotted in February of 2016. It uses a variety of methods to spread, including email attachments and malicious URLs. It encrypts the files on the infected computer and demands a ransom be paid in order to decrypt the files. The virus has caused over $1 million in damages.
The fifth most deadly computer virus is the Cryptolocker virus. It is a ransomware virus that was first spotted in September of 2013. It uses a variety of methods to spread, including email attachments and malicious URLs. It encrypts the files on the infected computer and demands a ransom be paid in order to decrypt the files. The virus has caused over $3 billion in damages.

How can I protect my computer from viruses?
There are a few steps you can take to protect your computer from viruses:
1. Install and update antivirus software. Antivirus software can help detect and remove viruses from your computer. Be sure to keep your antivirus software up-to-date, as new viruses are constantly being created.
2. Don’t click on links or open attachments from strangers. If you don’t know the sender of an email or message, don’t click on any links or open any attachments that it contains. These could contain viruses that will infect your computer.
3. Keep your software up-to-date. Software updates often include security updates that can help protect your computer from new viruses.
4. Back up your files. This way, if your computer does get infected with a virus, you’ll be able to restore your files from a backup.
What is the most dangerous computer virus in terms of its ability to cause damage?
caused damage as the title
While there are many computer viruses that can cause damage to your computer, there is one in particular that is considered to be the most dangerous. This virus is known as the WannaCry ransomware.
WannaCry is a type of malware that encrypts your files and then demands a ransom in order to decrypt them. It first appeared in May of 2017 and quickly spread around the world, affecting hundreds of thousands of computers in over 150 countries.
WannaCry is particularly dangerous because it takes advantage of a vulnerability in Windows that was first discovered by the United States National Security Agency (NSA). This vulnerability, known as “EternalBlue”, allowed WannaCry to spread quickly and infected computers that did not have the latest security updates installed.
While Microsoft did release a security update to patch the EternalBlue vulnerability, many computers had not yet installed it when WannaCry began spreading. This left them vulnerable and resulted in a large number of computers being infected.
The WannaCry ransomware attack caused billions of dollars in damage and caused many businesses and organizations to shut down temporarily while they dealt with the fallout. Hospitals, banks, and government agencies were all affected by the attack.
While the WannaCry ransomware attack was the most damaging and widespread attack of its kind, it is not the only dangerous virus out there. Other viruses, like the Petya virus, can also cause significant damage.
Petya is a type of malware that encrypts your hard drive and then prevents you from booting up your computer. This can render your computer unusable and can cause you to lose all of your data.
Petya first appeared in 2016 and was used in a number of attacks, the most notable of which was the “NotPetya” attack that took place in June of 2017. This attack affected computers in over 65 countries and caused billions of dollars in damage.
While WannaCry and Petya are considered to be the most dangerous viruses in terms of their ability to cause damage, there are other viruses that can also be damaging. Some, like the CryptoLocker virus, can encrypt your files and then hold them ransom until you pay a fee to decrypt them.
Others, like the Zeus virus, can steal your banking information and lead to identity theft. And still others, like the Blaster virus, can disable your computer or network.
The most dangerous virus is the one that is currently causing the most damage. However, all viruses have the potential to cause damage, and it is important to take steps to protect your computer from them.
In recent years, computer viruses have become increasingly sophisticated and dangerous. While there are many different types of malware, some viruses are more destructive and costly than others. Here are some of the most dangerous computer viruses in recent history.
1. WannaCry
WannaCry is a ransomware virus that first appeared in May 2017. It quickly spread around the globe, affecting more than 200,000 computer systems in 150 countries. The virus encrypts files on infected computers and demands a ransom payment in order to decrypt them. WannaCry has caused billions of dollars in damage and is considered one of the most destructive viruses in history.
2. NotPetya
NotPetya is another ransomware virus that first appeared in June 2017. Unlike WannaCry, which primarily affected Windows systems, NotPetya primarily affected computers running on the Windows 7 operating system. This virus also spread quickly, affecting more than 12,000 computer systems in at least 65 countries. NotPetya caused major disruptions and damage to businesses, with some estimates suggesting the virus cost businesses billions of dollars.
3. Melissa
Melissa is a virus that first appeared in March 1999. It spread quickly via email, with infected attachments being sent to contacts in the victims’ address book. Melissa caused major disruptions to email systems and infected an estimated one million computers. The virus was eventually traced to its creator, who was sentenced to 20 months in prison.
4. ILOVEYOU
ILOVEYOU is a virus that first appeared in May 2000. Like Melissa, it spread quickly via email, with infected attachments being sent to contacts in the victims’ address book. ILOVEYOU caused significant damage, with estimates suggesting it caused billions of dollars in damage. The virus was eventually traced to its creators, who were both sentenced to prison.
5. Code Red
Code Red is a virus that first appeared in July 2001. It affected computers running on the Microsoft Windows operating system and caused them to display a message stating “Hacked By Chinese!” Code Red was used in a number of high-profile attacks, including against the White House website. The virus was eventually traced to its creator, who was sentenced to prison.
Computer viruses are becoming more and more sophisticated and dangerous. WannaCry, NotPetya, Melissa, ILOVEYOU, and Code Red are just some of the most destructive and costly viruses in recent history. As viruses continue to evolve, it is important to be aware of the dangers they pose and take steps to protect your computer and data.
