What are the most dangerous computer viruses in existence?
There is no doubt that computer viruses are becoming more and more dangerous with each passing day. As technology advances, so do the methods and motivations of cyber criminals. Here are some of the most dangerous computer viruses in existence today.
Ransomware
Ransomware is a type of malware that encrypts a victim’s files and holds them ransom until a payment is made. Often, the ransom is demanded in Bitcoin or another cryptocurrency. This makes it difficult to trace the criminals and almost impossible to get the victim’s files back without paying the ransom.
WannaCry
WannaCry is a particularly nasty piece of ransomware that hit thousands of computers across the globe in May of 2017. One of the most alarming things about WannaCry is that it exploits a vulnerability in Microsoft Windows that was first discovered and developed by the United States National Security Agency.
NotPetya
NotPetya is another ransomware virus that emerged in June of 2017. This one is particularly dangerous because it not only encrypts a victim’s files, but it also renders their computer unusable. In other words, even if you were to pay the ransom, there is no guarantee that you would get your files back or that your computer would be usable again.
Cryptojacking
Cryptojacking is a type of malware that allows criminals to use a victim’s computer to mine cryptocurrencies. This can slow down a victim’s computer and use up a lot of their electricity. In some cases, it can even cause physical damage to the computer.
Spyware
Spyware is a type of malware that allows cyber criminals to collect victim’s personal information, such as passwords, credit card numbers, and banking information. This information can then be used to commit identity theft or fraud.
Adware
Adware is a type of malware that displays unwanted advertising on a victim’s computer. This can be in the form of pop-up ads, banner ads, or even full-screen ads. While this might not seem as dangerous as some of the other types of malware on this list, it can be extremely annoying and can lead to a victim clicking on a malicious ad and infecting their computer with other types of malware.
These are just a few of the most dangerous computer viruses in existence today. As technology advances, so do the methods and motivations of cyber criminals. It is important to be aware of the dangers of clicking on unwanted links or opening email attachments from unknown sender. It is also important to have a good anti-virus program installed on your computer and to keep it up-to-date.

Most dangerous computer viruses
There are many computer viruses that can be extremely dangerous, and it can be hard to know which ones are the most dangerous. Here is a list of the most dangerous computer viruses:
1. WannaCry
WannaCry is a ransomware virus that was first seen in May 2017. It targets Windows systems and encrypted files on the infected computer, making them inaccessible. It then demands a ransom be paid in order to decrypt the files. WannaCry is particularly dangerous because it can spread itself quickly and easily to other computers on the same network. It has caused millions of dollars in damage and has even been linked to some deaths.
2. NotPetya
NotPetya is another ransomware virus that was first seen in June 2017. It shares many similarities with WannaCry, but is even more destructive. It not only encrypts files, but also renders the entire computer unusable. NotPetya has caused billions of dollars in damage and is considered one of the most devastating cyber-attacks in history.
3. Zeus
Zeus is a virus that is used to steal banking information. It is often spread through phishing emails that look like they are from a legitimate bank or financial institution. Once the victim clicks on the link or attachment in the email, their computer becomes infected with Zeus. It can then be used to steal passwords, account numbers, and other sensitive information. Zeus is particularly dangerous because it can be used to empty bank accounts and cause a lot of financial damage.
4. CryptXXX
CryptXXX is a ransomware virus that was first seen in April 2016. It encrypts files on the infected computer and demands a ransom be paid in order to decrypt them. CryptXXX is particularly dangerous because it is constantly evolving and changing, making it hard to defend against. It has also been known to infect backup files, making it even more difficult to recover data.
5. Locky
Locky is a ransomware virus that was first seen in February 2016. It targets both Windows and Linux systems and encrypts files on the infected computer. It then demands a ransom be paid in order to decrypt the files. Locky is particularly dangerous because it uses a wide variety of methods to spread itself, including email attachments, malicious websites, and drive-by downloads. It has also been known to encrypt backup files, making it even more difficult to recover data.
These are just some of the most dangerous computer viruses out there. Be sure to keep your antivirus software up to date and be careful when clicking on links or opening attachments in emails.
