What is the most dangerous computer virus in the world?
in the title
There is no definitive answer to this question as it depends on a number of factors, including the specific Computer Virus, the operating system it is targeting, and the level of security on the device. However, some of the most dangerous computer viruses in the world include:
1. WannaCry
WannaCry is a ransomware virus that targets the Microsoft Windows operating system. It was first discovered in May 2017 and quickly spread around the world, encrypting data on millions of devices and demanding payments in Bitcoin in order to unlock the files. WannaCry is considered particularly dangerous as it takes advantage of a security flaw in Windows known as EternalBlue, which allows the virus to spread quickly and easily from one device to another.
2. NotPetya
NotPetya is another ransomware virus that emerged in June 2017. Unlike WannaCry, which primarily targets Windows, NotPetya is designed to infect as many different types of devices and operating systems as possible, including Linux and macOS. NotPetya is also notable for its use of the EternalBlue exploit, as well as a secondary exploit called EternalRoman, which allows it to spread even more quickly and easily.
3. Stuxnet
Stuxnet is a computer worm that was first discovered in 2010. It is believed to have been created by the United States and Israel in order to sabotage the Iranian nuclear program. However, the worm ended up escaping the Iranian facility it was designed to target and eventually spread to other devices around the world, causing millions of dollars in damage. While Stuxnet is not specifically designed to infect and encrypt data like ransomware viruses, it is still considered one of the most dangerous computer viruses in the world due to its potential for causing widespread mayhem.
4. Flame
Flame is a computer virus that was discovered in 2012. It is notable for its sophistication, as it is considerably more complex than most other viruses. Flame is believed to have been created by the United States, Israel, and possibly other countries, and is thought to have been used in targeted attacks against Iranian computers. While Flame is not as well-known as some of the other viruses on this list, it is still considered to be extremely dangerous due to its sophisticated design and its potential for being used in future attacks.
5. Zeus
Zeus is a trojan horse virus that was first discovered in 2007. It is designed to steal sensitive information, such as banking details, from infected devices. Zeus is particularly dangerous as it is often used in so-called “phishing” attacks, where unsuspecting victims are enticed into clicking on malicious links or attachments. Once infected, the Zeus virus can be used to steal sensitive information or to allow remote access to the infected device.
These are just some of the most dangerous computer viruses in the world. While there is no sure way to prevent infection, staying up-to-date with security patches and using a reputable antivirus program can help to reduce the risk.

What are the most widespread computer viruses in the world?
Widespread computer viruses are those that have been particularly active and destructive, or have infected a large number of computers around the world. There are a number of ways to measure virus activity, but one common metric is the number of unique infections, which can give us a good idea of which viruses are the most widespread.
According to this metric, the most widespread computer virus in the world is the WannaCry ransomware virus, which first appeared in May of 2017. WannaCry quickly spread across the globe, infecting more than 230,000 computers in over 150 countries. The virus exploited a vulnerability in Microsoft Windows, and encrypted victims’ files, demanding a ransom be paid in order to decrypt them. While some victims were able to restore their files from backups, many were not, and WannaCry is estimated to have caused billions of dollars in damage.
Another highly widespread virus is the Cryptocurrency Miner Virus, which is a type of malware that hijacks a victim’s computer resources in order to mine cryptocurrency. This virus began appearing in late 2017, and by early 2018, it was estimated to have infected more than 2 million computers. The Cryptocurrency Miner Virus is often spread through malicious advertisements, or by websites that have been compromised by the virus. Once a computer is infected, the virus can slow down the victim’s machine, and use their resources to mine for cryptocurrency without their knowledge or consent.
These are just two of the most widespread computer viruses in the world; there are many others that have caused significant damage, and which continue to spread. As new vulnerabilities are discovered, and new ways to spread malware are devised, it’s likely that we will see more widespread viruses in the future. In order to protect your computer, it’s important to keep your software up to date, and to be careful about the websites you visit and the links you click.
