What is the most destructive pc virus ever made?

There are a few contenders for the most destructive virus ever made. One is the Mydoom virus, which was released in 2004. It caused widespread havoc, infecting millions of computers and causing an estimated $38 billion in damages. Another contender is the Storm Worm, which was released in 2007. It was responsible for a massive botnet which was used to launch distributed denial of service attacks and send out billions of spam emails. It is estimated to have caused over $1 billion in damages.

Then there is the WannaCry ransomware attack, which hit in May of 2017. It used a vulnerability in Microsoft Windows to spread quickly and encrypt users’ files, demanding a ransom in order to decrypt them. It caused an estimated $4 billion in damages and crippled many organizations, including the UK’s National Health Service.

Mydoom and Storm caused a lot of financial damage, while WannaCry caused a lot of disruption and chaos. In the end, it’s hard to say which is the most destructive, as they all caused a great deal of damage in their own way.

What are the most dangerous computer viruses?

There are many different types of computer viruses out there, but some are definitely more dangerous than others. Here is a list of the most dangerous computer viruses that you should know about:

1. WannaCry

WannaCry is a ransomware virus that was first seen in May of 2017. It quickly spread around the world, affecting thousands of businesses and individuals. The virus encrypts files on an infected computer and then demands a ransom be paid in order to decrypt them. Unfortunately, even if the ransom is paid, there is no guarantee that the files will be decrypted. This virus has caused a lot of financial damage and disrupted many businesses.

2. Petya/NotPetya

Petya is a virus that first surfaced in 2016. It is a type of ransomware that encrypts a computer’s hard drive, making it impossible to access the files. Unlike WannaCry, there is no way to decrypt the files even if the ransom is paid. This virus caused a lot of damage to businesses, particularly in Ukraine where it first originated.

3. Locky

Locky is a ransomware virus that was first seen in February of 2016. It is spread through spam emails that contain attachments that, when opened, infect the computer with the virus. Locky will then encrypt files on the computer and demand a ransom be paid in order to decrypt them. As with WannaCry, even if the ransom is paid there is no guarantee that the files will be decrypted.

4. CryptoLocker

CryptoLocker is a ransomware virus that was first seen in September of 2013. It is spread through email attachments and infected websites. Once a computer is infected, the virus will encrypt files and demand a ransom be paid in order to decrypt them. This virus is particularly dangerous because it can encrypt not only files on the infected computer, but also files on any connected network drives.

5. Zeus

Zeus is a type of malware that is used to steal information. It is usually spread through phishing emails that contain attachments or links that, when clicked, will infect the computer with the virus. Once a computer is infected, the Zeus virus will be able to steal passwords, banking information, and other sensitive data. This information can then be used to commit fraud or theft.

These are just a few of the most dangerous computer viruses out there. Be sure to protect your computer by installing an antivirus program and keeping it up-to-date. Avoid clicking on links or opening attachments from unknown sources. And never pay a ransom if your computer is infected with ransomware.

What is the most dangerous computer virus in the world?

The most dangerous computer virus in the world is the WannaCry ransomware virus. This virus encrypts files on the infected computer and demands a ransom be paid in order to decrypt the files. This virus has caused billions of dollars in damage and has infected computers in over 150 countries.

How do computer viruses spread?

Computer viruses are programs that copy themselves onto your computer without your permission. They can damage your computer, delete your files, and even steal your personal information. Some viruses are so powerful that they can even take control of your computer.

There are many ways that computer viruses can spread. They can come from email attachments, infected websites, or even from USB drives. Once a virus is on your computer, it can spread to other computers on your network.

Most viruses spread by replicating themselves. They attach themselves to files and programs on your computer and then when you run that file or program, the virus copies itself onto your computer. It then looks for other computers on your network and tries to copy itself onto those computers as well.

Some viruses spread by email attachments. These viruses can infect your computer just by you opening the email. The virus will then start replicating itself and will try to send itself to everyone in your address book.

Other viruses spread by infected websites. When you visit an infected website, the virus can install itself onto your computer. The virus can then track what websites you visit and what you do online.

USB drives can also spread viruses. If you plug in a USB drive that has a virus on it, the virus can copy itself onto your computer. Once the virus is on your computer, it can spread to other computers when you plug the USB drive into those computers.

The most dangerous viruses are the ones that take control of your computer. These viruses can delete your files, steal your personal information, and even send spam emails from your account.

You can protect your computer from viruses by using a good antivirus program. Antivirus programs scan your computer for viruses and remove them. You should also scan any email attachments and USB drives before you open them.
