What is the most dangerous computer virus in the world?

There are many computer viruses that have caused serious harm over the years, but there is one in particular that stands out as the most dangerous. The WannaCry ransomware attack was a global cyberattack that hit businesses and organizations in more than 150 countries. The WannaCry virus encrypted files on victims’ computers and demanded a ransom payment in order to regain access to them. This attack caused billions of dollars in damage and disrupted critical services around the world, including hospital care in the UK. While there have been other ransomware attacks since then, WannaCry remains the most damaging and dangerous virus to date.

What are the most dangerous computer viruses in the world?

Computer viruses come in many shapes and sizes, with new ones emerging all the time. Some are more dangerous than others, and can cause serious damage to your computer or even steal your personal information. Here are some of the most dangerous computer viruses in the world:

1. WannaCry

WannaCry is a ransomware virus that emerged in May 2017. It quickly spread around the world, infecting more than 230,000 computers in 150 countries. WannaCry encrypted users’ files and demanded a ransom of $300-$600 in Bitcoins in order to decrypt them. The virus caused massive disruption, with hospitals, businesses and schools all affected.

2. NotPetya

NotPetya is another ransomware virus, which emerged in June 2017. It primarily infected computers in Ukraine, but also spread to other countries including the UK, US and Russia. NotPetya encrypted users’ files and demanded a ransom of $300 in Bitcoins. However, unlike WannaCry, there was no way to decrypt the files – meaning that users who paid the ransom simply lost their money.

3. Zeus

Zeus is a virus that is used to steal people’s personal and financial information. It can infect your computer in various ways, including through email attachments and websites that have been compromised. Once installed on your computer, Zeus will collect sensitive information such as passwords and bank account details. It then sends this information back to the hackers, who can use it to commit fraud or steal your money.

4. Cryptolocker

Cryptolocker is a ransomware virus that was first seen in 2013. It infects computers through email attachments and compromised websites. Once installed, it will encrypt the files on your computer and demand a ransom in order to decrypt them. Cryptolocker is particularly dangerous as it uses strong encryption, which makes it very difficult to decrypt the files without paying the ransom.

5. SpyEye

SpyEye is a virus that is used to steal people’s personal and financial information. It works in a similar way to Zeus, by infecting computers through email attachments and compromised websites. Once installed, it will collect sensitive information such as passwords and bank account details. It then sends this information back to the hackers, who can use it to commit fraud or steal your money.
