What are some of the most dangerous computer viruses in existence?
There are an endless amount of computer viruses that exist, with new ones popping up every day. While there are too many to name, we’ve compiled a list of some of the most dangerous viruses in existence.
1. WannaCry
WannaCry is a ransomware virus that made headlines in 2017 for encrypting important files on infected computers and demanding a ransom payment in order to decrypt them. This virus targets Windows computers and can spread quickly through networks. WannaCry is particularly dangerous because it takes advantage of a vulnerability in Windows that had been previously identified and patched by Microsoft – but not all computers had installed the updates.
2. NotPetya
NotPetya is a virus that shares many characteristics with WannaCry, in that it is also ransomware that encrypts files on an infected computer. However, NotPetya is even more destructive, as it not only encrypts files but also prevents the entire system from booting up. This means that even if a ransom is paid, the victim will not be able to access their files or use their computer. NotPetya also has the ability to spread quickly through networks, making it even more dangerous.
3. Cryptolocker
Cryptolocker is a type of ransomware that specifically targets data that is important to businesses, such as financial records and confidential customer information. This virus puts businesses at risk of not being able to operate if their important data is encrypted and they can’t access it. In some cases, even if a ransom is paid, the files may not be decrypted and the businesses may never recover their data.
4. Zeus
Zeus is a virus that is used by cyber criminals to steal banking information, such as login credentials and passwords. This virus can infect a computer when the user visits a website that has been infected with Zeus or downloads a malicious email attachment. Once the virus is on the computer, it will start recording the user’s keystrokes in order to steal sensitive information. Zeus is particularly dangerous because it can be used to empty a bank account or make fraudulent charges.
5. iloveyou
The iloveyou virus is a malicious email attachment that, when opened, installs a worm on the victim’s computer. This worm then proceeds to send itself to all of the victim’s email contacts. The iloveyou virus is particularly dangerous because it can spread very quickly and can cause a lot of damage to computers and networks.
These are just a few of the most dangerous computer viruses in existence. While there are many other viruses out there, these are some of the most destructive and harmful. If you suspect that your computer may be infected with a virus, it’s important to run a scan with antivirus software and to not open any email attachments or click on any links from unknown sources.
What is the most common type of computer virus?
There are many types of computer viruses, but according to Kaspersky Lab, the most common type of virus is a Trojan. Trojans are malicious programs that disguise themselves as legitimate software. They can be used to steal personal information, or to take control of your computer.
