What are viruses computer?
A virus is a type of malware that can infect a computer system without the user’s consent or knowledge. Once a virus is installed on a system, it can spread to other systems and can cause a lot of damage.
There are different types of viruses, but the most common ones are Trojan horses and Worms. Trojan horses are programs that disguise themselves as something else, such as a software application or a video file. Worms are self-replicating programs that can spread quickly from one computer to another.
Viruses can cause a lot of damage to a computer system. They can delete files, corrupt data, and even crash the system. They can also steal personal information from the system or install other malware on the system.
Viruses are often spread through email attachments, infected websites, and peer-to-peer file sharing networks. They can also be spread through USB drives, CDs, and other storage devices.
There are a few things that you can do to protect your computer from viruses. You should always have a good antivirus program installed on your system, and you should keep it up-to-date. You should also be careful when opening email attachments and clicking on links in emails. You should also avoid downloading files from unknown sources.

What is viruses in a computer?
A computer virus is a type of malware that can copy itself and infect a computer. Viruses can cause data loss or even destruction of the computer.
There are many different types of computer viruses. Some viruses are designed to spread quickly and cause as much damage as possible. Others are designed to steal information or harm the computer.
Viruses are often spread through email attachments, downloads, or visiting infected websites. They can also be spread through USB drives, flash drives, or other forms of removable media.
It is important to have antivirus software installed on your computer to help protect it from viruses. Antivirus software can detect and remove viruses from your computer.
What are computer viruses and its types?
A computer virus is a type of malicious software that, once installed on a computer, can replicate itself and spread to other computers.
There are many different types of computer viruses, but the most common ones are file infectors, boot sector viruses, and Trojan horses.
File infectors are the most common type of computer virus. These viruses attach themselves to executable files and spread when the files are copied or shared.
Boot sector viruses are viruses that infect the boot sector of a computer’s hard drive. These viruses can spread to other computers when the hard drive is shared or copied.
Trojan horses are programs that appear to be helpful or desirable but actually contain a virus or other type of malware. Trojan horses can be spread through email, websites, and other means.
Computer viruses can cause a variety of problems on a computer, including system crashes, reduced performance, and data loss.
It is important to have a good antivirus program installed on your computer to help protect it from viruses. Antivirus programs can detect and remove viruses, and they can also help protect your computer from new viruses.
What is virus in simple words?
A virus is a small, infectious agent that can replicate inside cells and spread from one organism to another. Viruses are often highly contagious and can cause a range of health problems, from mild colds and flus to deadly infections.
There are many different types of viruses, and they can infect a wide range of organisms, including humans, animals, plants, and even bacteria. Some viruses are specific to a certain species, while others can infect more than one type of organism.
Viruses are not alive in the traditional sense, but they do have some characteristics of living organisms. They are made up of genetic material (DNA or RNA) and a protein coat, and they can infect and replicate inside host cells.
Viruses are spread through contact with infected tissues, blood, or bodily fluids, as well as through the air or water. They can also be spread through contact with contaminated surfaces, such as doorknobs, door handles, and countertops.
The best way to protect yourself from viruses is to practice good hygiene and to avoid contact with sick or infected people. You can also reduce your risk of exposure to viruses by washing your hands regularly and avoiding close contact with people who are sick.
How computer virus is created?
How computer virus is created?
Computer viruses are created by individuals or groups of individuals with malicious intent. They can be created in a variety of ways, but most commonly, they are created by programming code that is executed when a user opens an infected file or attachment.
There are many different ways to create a computer virus, but most of them involve using programming code to exploit vulnerabilities in software or operating systems. For example, a virus might be programmed to take advantage of a security flaw in a web browser that allows it to execute automatically when the user visits a website.
Viruses can also be spread through social media, email, and other online channels. In many cases, they are spread through infected files or attachments that are sent to unsuspecting users. Once the user opens the infected file or attachment, the virus is executed and begins to spread to other devices on the network.
It’s important to note that not all computer viruses are created with the intention of causing harm. Some viruses are created for the purpose of testing or demonstrating security vulnerabilities. However, the majority of viruses are created with the intent of causing harm or stealing information.
How can you protect yourself from computer viruses?
The best way to protect yourself from computer viruses is to use an antivirus program and keep it up-to-date. Antivirus programs can detect and prevent infections from viruses, and they can also help to remove viruses if they do become infected.
In addition, you should always be careful about what files and attachments you open, and you should never click on links or download files from suspicious or unknown sources.
What is a virus short definition?
A virus is a type of malware that, once installed on a device, can replicate itself and spread to other devices. Viruses can cause a variety of damage to a device, including crashing the system, stealing data, and spying on the user.
What are the 3 types of viruses?
There are three types of viruses: single-stranded RNA viruses, double-stranded DNA viruses, and retroviruses.
Single-stranded RNA viruses are the simplest type of virus. They have a single strand of RNA (ribonucleic acid) as their genetic material. This type of virus can only reproduce inside a living cell, where it hijacks the cell’s machinery to make copies of itself.
Double-stranded DNA viruses are more complex than single-stranded RNA viruses. They have a double strand of DNA as their genetic material. This type of virus can reproduce both inside and outside of living cells.
Retroviruses are the most complex type of virus. They have a single strand of RNA as their genetic material, but they also have a enzyme called reverse transcriptase. This enzyme allows the virus to convert its RNA into DNA. This DNA can then be integrated into the host cell’s DNA, where it can replicate along with the host cell.
What’s the best definition of a virus?
There are many different definitions of a virus, but what is the best definition?
One definition of a virus is “a submicroscopic, obligate, intracellular parasite that replicates within a host’s cells, often causing disease.” This definition is from the Merriam-Webster dictionary.
Another definition of a virus is “a self-replicating agent that typically contains DNA or RNA but lacks the ability to replicate autonomously and that is typically parasitic on a living cell.” This definition is from the Oxford Dictionaries.
Both of these definitions are good, but I think the best definition is from the Oxford Dictionaries, because it includes the fact that viruses are parasites. This is important because viruses need a host in order to replicate.
