What is the most deadliest computer virus and what does it do?
There are many different types of computer viruses, and each one has the potential to cause damage in a variety of ways. Some viruses are designed to delete important files, while others may encrypt files or make changes to the way your computer operates. The most deadly viruses are those that are able to spread quickly and cause extensive damage.
One of the most deadly viruses is the WannaCry virus, which was responsible for a global ransomware attack in 2017. This virus encrypted files on infected computers and demanded a ransom be paid in order to decrypt them. This attack caused billions of dollars in damage and affected thousands of organizations, including hospitals, businesses, and government agencies.
Another deadly virus is the Conficker virus, which was first discovered in 2008. This virus spread quickly and caused a great deal of damage by changing the way computers operate and making it difficult for users to access important files. This virus also caused financial damage by stealing sensitive information, such as bank account numbers and passwords.
These are just two examples of the many different types of computer viruses that can cause serious damage. It’s important to have a good antivirus program installed on your computer and to be cautious when opening email attachments or clicking on links from unknown sources.

What is the most frequently asked question about computer viruses?
Computer viruses are among the most deadliest of threats to both personal and business computers today. Many people believe that a virus is only something that can come through email, but in reality, there are many ways that viruses can be contracted. Not only can they come through email, but they can also come through websites, downloads, and even removable media like USB drives. The most deadly virus might not be the one that causes the most damage, but the one that is the most difficult to remove. Some of the most frequently asked questions about computer viruses are:
-What is a computer virus?
-How do computer viruses spread?
-How can I protect my computer from viruses?
-What are the symptoms of a computer virus?
-How can I tell if my computer has a virus?
-What is the most deadly computer virus?
A computer virus is a program or code that is designed to replicate itself and spread from one computer to another. viruses can corrupt or delete data, slow down your computer, or even crash your system. Viruses can be contracted in a number of ways, the most common being through email attachments, websites, downloads, and removable media.
How do computer viruses spread?
Computer viruses spread by replicating themselves and attaching themselves to programs or files on your computer. When you open a file or program that has a virus, the virus code will execute and the virus will attempt to spread to other files and programs on your computer. Computer viruses can also spread through email attachments, websites, downloads, and removable media.
How can I protect my computer from viruses?

Second, be careful about what emails you open and what websites you visit. Third, don’t download files or programs from websites that you don’t trust. Fourth, don’t plug in removable media (like USB drives) from other computers unless you trust the source.
What are the symptoms of a computer virus?
The symptoms of a computer virus can vary depending on the type of virus and the level of damage it does. Some common symptoms include:
-Your computer is running slow
-Your computer crashes or freezes
-You see strange error messages
-Files or programs are deleting themselves
-You see new files or programs that you didn’t install
How can I tell if my computer has a virus?

What is the most deadly computer virus?
The most deadly computer virus is the one that is the most difficult to remove. Some viruses are so sophisticated that they can disable your antivirus software and prevent you from removing them. Other viruses can delete or corrupt critical files on your computer, making it difficult or impossible to recover your data.
How do computer viruses spread?
A computer virus is a malicious code that replicates itself by copying itself into another program, computer boot sector or document and changes the way a computer works. A virus cannot spread or infect without a human action, such as running an infected program or opening an infected document.
The first thing a virus does is make copies of itself. Then it attempts to insert those copies into other programs or documents on the same computer. Finally, it tries to spread to other computers.
Viruses spread in a few different ways. The most common is when you run an infected program or open an infected document. The virus copies itself into memory and then looks for other programs to infect. When it finds one, it copies itself into that program. This process can continue, infecting more and more programs on a single computer.
Another way viruses spread is by being included in an email attachment. When you open the attachment, the virus copies itself into your email program. Then, when you send emails to other people, the virus copies itself into those emails. So, each email you send can infect other computers.
A virus can also spread by being included in a download, such as a program or document. When you download the infected file, the virus copies itself onto your computer. From there, it can infect other programs and documents.
Once a virus is on a computer, it can do different things. Some viruses display annoying messages or ads. Some delete files. Others lock you out of your computer until you pay a ransom. Some viruses do nothing at all.
The most dangerous viruses are called ransomware. They encrypt your files so you can’t access them. Then, they demand you pay a ransom to get the encryption key. If you don’t pay, you lose access to your files forever.
Some of the most deadly viruses include:
1. CryptoLocker
CryptoLocker was a ransomware virus that was first seen in 2013. It spread by being included in email attachments. When you opened the attachment, the virus would encrypt your files. Then, it would display a message demanding you pay a ransom to get the encryption key. If you didn’t pay, you lost access to your files.
2. WannaCry
WannaCry was a ransomware virus that spread quickly around the world in 2017. It spread by taking advantage of a security vulnerability in Microsoft Windows. When it infected a computer, it would encrypt the files. Then, it would display a message demanding you pay a ransom to get the encryption key. If you didn’t pay, you lost access to your files.
3. NotPetya
NotPetya was a virus that spread quickly around the world in 2017. It was disguised as ransomware, but it was actually designed to destroy data. It spread by taking advantage of a security vulnerability in Microsoft Windows. When it infected a computer, it would encrypt the files. Then, it would display a message demanding you pay a ransom to get the encryption key. However, even if you paid the ransom, you would not get the encryption key.
4. ILOVEYOU
ILOVEYOU was a virus that spread quickly around the world in 2000. It spread by being included in email attachments. When you opened the attachment, the virus would send itself to everyone in your address book. It would also delete important files on your computer.
5. Melissa
Melissa was a virus that spread quickly in 1999. It spread by being included in email attachments. When you opened the attachment, the virus would send itself to everyone in your address book. It would also insert random text into your documents.
