ever
There are many schools of thought when it comes to the most dangerous computer virus ever. Many people believe that it is the WannaCry virus that hit in May of 2017. This virus was particularly dangerous because it not only impacted individuals and businesses, but it also crippled hospitals and other critical infrastructure. The WannaCry virus encrypted data and demanded a ransom for the decryption key, which caused a lot of havoc for those who were infected. Another contender for the most dangerous virus ever is the Petya virus, which also hit in 2017. This virus was particularly dangerous because it not only encrypted data, but it also destroyed the master boot record, making it impossible to boot up the computer. This virus was also responsible for a lot of financial damage, as it hit many businesses hard.

Computer viruses come in many shapes and sizes and can wreak havoc on your computer, causing everything from slow performance to data loss. Some of the most dangerous viruses can even render your computer unusable.
While there are thousands of different computer viruses out there, some are more dangerous than others. Here is a list of some of the most dangerous computer viruses:
1. WannaCry
WannaCry is a ransomware virus that was first released in May of 2017. It quickly spread around the world, affecting over 200,000 computers in 150 countries. WannaCry encrypts files on infected computers and demands a ransom be paid in order to decrypt them.
2. NotPetya
NotPetya is another ransomware virus that was released in June of 2017. Like WannaCry, it quickly spread around the world, affecting thousands of computers. NotPetya differs from WannaCry in that it not only encrypts files, but also prevents infected computers from booting up properly.
3. Zeus
Zeus is a virus that is used to steal banking information. It is a type of malware known as a Trojan horse. Zeus is particularly dangerous because it is very difficult to detect and can easily go undetected for months, or even years.
4. Cryptolocker
Cryptolocker is a ransomware virus that was first released in September of 2013. It encrypted the files on infected computers and demanded a ransom be paid in order to decrypt them. Cryptolocker was particularly dangerous because it used strong encryption that was very difficult to break.
5. Stuxnet
Stuxnet is a virus that was specifically designed to target industrial control systems. It is widely believed to have been created by the United States and Israel in order to sabotage the Iranian nuclear program. Stuxnet is considered to be the most sophisticated computer virus ever created and is extremely dangerous.
These are just a few of the most dangerous computer viruses. There are thousands of others that can cause serious damage to your computer. It is important to have antivirus software installed on your computer and to keep it up-to-date in order to protect yourself from these threats.

of 2017
Most computer viruses are relatively harmless and cause little more than a temporary nuisance. However, some viruses can be quite dangerous and have the potential to cause serious harm to your computer. The most dangerous computer virus is the WannaCry virus, which was first discovered in May of 2017. The WannaCry virus attacks any computer that is running the Windows operating system. Once a computer is infected with the WannaCry virus, it will encrypt all of the files on the hard drive and will display a message that demands a ransom be paid in order to decrypt the files. The WannaCry virus has caused havoc around the world, with estimates of over 200,000 computers being infected in over 150 countries. Hospitals, businesses, and government agencies have all been affected by the WannaCry virus, with many of them being forced to shut down their systems until they can find a way to remove the virus. The WannaCry virus is considered to be the most dangerous computer virus because it has the potential to cause serious damage to a computer, and it can spread quickly and easily to other computers.
