A computer virus is a type of malicious software program that, when executed, can replicate itself and spread to other computers. Viruses can damage files, or even delete them, and can also make computers crash. Some viruses are designed to spread spam or hijack computers for criminal activities.
Viruses are typically spread through email, infected websites, or removable storage media, such as USB drives. They can also be spread through social media platforms and instant messaging applications.
There are many different types of computer viruses, but the most common ones are Trojans, worms, and ransomware.
Trojans are programs that appear to be helpful or desirable, but actually contain harmful or destructive code. Worms are self-replicating programs that can spread rapidly through networks and infect vulnerable systems. Ransomware is a type of virus that encrypts files on a user’s computer and then demands a ransom payment to decrypt them.
The best way to protect your computer from viruses is to install anti-virus software and keep it up-to-date. You should also be careful about where you download software and files from, and never open email attachments or links from unknown sources.

What is a computer virus?
A computer virus is a type of malware that, once it has infected a computer, attaches itself to executable files or documents and spreads from one computer to another. Infected files may be replicated and spread as if they were viruses.
What are the effects of a computer virus?
The effects of a computer virus can be devastating. Some viruses can delete or corrupt files, while others can steal personal information or passwords. Some viruses can even completely destroy a computer’s operating system.
How can you protect your computer from a virus?
There are several ways to protect your computer from a virus. One of the most important is to keep your computer’s operating system and software up-to-date. You should also install a firewall and a good antivirus program, and keep both of them up-to-date. You should also be careful when you open email attachments and click on links in emails, and never download software from untrustworthy sources.

What even is a computer virus?
A computer virus is a type of malicious software that, when executed, replicates itself by infecting other computer programs and files. It can damage or delete data, spread to other computers, and create a security breach.
The term “virus” is also used to refer to other types of malware, including ransomware, spyware, and Trojans.
How do computer viruses spread?
Most computer viruses are spread through email attachments, infected websites, or file-sharing networks. They can also be spread through USB drives, social media, and other forms of electronic communication.
How can you protect your computer from viruses?
You can protect your computer from viruses by installing antivirus software and keeping it up-to-date. You should also be careful about where you download files from and what you open attachments from. You should also avoid clicking on links or downloading files from suspicious websites.
What are the 3 types of viruses?
There are three types of viruses: bacteriophages, DNA viruses, and RNA viruses.
Bacteriophages are viruses that infect bacteria. They are the most common type of virus and are found in almost all environments. Bacteriophages are made of DNA or RNA and can have a protein coat.
DNA viruses are viruses that infect cells and use the cells’ DNA to make new viruses. They can cause a wide variety of diseases in animals and plants. DNA viruses are made of DNA and can have a protein coat.
RNA viruses are viruses that infect cells and use the cells’ RNA to make new viruses. They can cause a wide variety of diseases in animals and plants. RNA viruses are made of RNA and can have a protein coat.
Why is it called a computer virus?
In computing, a computer virus is a type of malicious software program that, when executed, replicates by inserting copies of itself into other executable software programs or documents. Viruses can impact your computer in a variety of ways, such as deleting files, corrupting data, or even rendering your computer inoperable.
While the term “computer virus” is often used to refer to any type of malicious software, the term is more properly limited to programs that replicate themselves. Other types of malicious software, such as trojans, worms, and ransomware, are not actually viruses, but are instead named after their respective payloads or behaviors.
The first computer virus was created in 1971 by Bob Thomas, a student at the University of California, Los Angeles. The virus, called “The Creeper”, was designed to move from one computer to another and display the message “I’m the creeper, catch me if you can.”.
The term “computer virus” was first coined in an article by Fred Cohen, who also coined the terms “worm” and “trojan horse”. In his paper, Cohen described a hypothetical virus that could infect computers and spread from one machine to another.
So why is it called a computer virus? The term is derived from the biological concept of a virus, which is a self-replicating program that inserts itself into other programs or documents in order to spread. Like biological viruses, computer viruses can cause serious damage to your computer, and can be difficult to remove.
So if you’re ever unfortunate enough to encounter a computer virus, be sure to take steps to remove it as quickly as possible. There are a number of free and paid antivirus programs available that can help you do this, and it’s important to keep your antivirus software up-to-date to help protect your computer from the latest threats.
What is virus in simple words?
A virus is a small, self-replicating program that can attach to other programs or files, making them difficult to delete. Viruses are often spread through email, or shared on file-sharing networks. They can also be installed on your computer when you visit a website that’s been infected.
Some viruses are designed to damage your computer or steal your data. Others are simply annoying, and can cause your computer to run slowly or crash.
The best way to protect yourself from viruses is to install anti-virus software on your computer and keep it up to date. You should also be careful about where you download files from, and never open email attachments from strangers.
How computer virus is created?
A computer virus is a type of malicious software program that, when executed, replicates itself by attaching itself to other programs or files on a computer, often causing them to malfunction.
There are many ways that a computer virus can be created. One common method is to use a virus-writing toolkit, which allows a user to create a virus by entering a few lines of code. These tools are often available on the internet for free, and can be used to create a virus that is specific to the type of computer it is infecting.
Another way to create a computer virus is to use a script, which is a set of instructions that can be used to carry out a particular task. Scripts can be used to create a virus that is specific to the type of computer it is infecting, as well as the operating system that is running on that computer.
Computer viruses can also be created by modifying existing malware programs, or by combining different pieces of code to create a new virus.
Once a computer virus has been created, it can be distributed in a number of ways. One common way is to send it as an email attachment. The virus can also be distributed through file sharing programs, or by uploading it to websites.
It is also possible for a computer virus to be spread through social media networks, such as Facebook and Twitter. And, of course, the virus can also be spread through infected floppy disks, CD-ROMs, and USB drives.
Computer viruses can be very dangerous, and can cause a lot of damage to a computer system. They can delete or corrupt files, slow down the computer, or even cause it to crash.
In order to protect your computer from computer viruses, it is important to install a good antivirus program and keep it up-to-date. You should also be very careful about the emails and attachments you open, and avoid downloading files from untrustworthy sources.
What is the first computer virus?
The first computer virus is widely considered to be the Elk Cloner, which was created in 1982 by Rich Skrenta. The virus infected Apple II computers and would display a message on the screen when the computer was turned on. The message read “Elk Cloner: The program with a personality. It’s got a lot of friends and it’s growing fast.”
