A computer virus is a type of malicious software that, once executed, replicates itself by copying itself to other files or programs on the computer. A virus can cause extensive damage to a computer system and its data.
Viruses are often spread through email attachments, infected websites, or peer-to-peer file sharing. Once a computer is infected, the virus can spread to other computers on the network.
Some common symptoms of a virus infection include:
-The computer runs slowly
-Pop-up ads appear on the screen
-The computer crashes or freezes
-The internet browser homepage has been changed
-The computer is unable to connect to the internet
To protect your computer from viruses, you should install antivirus software and keep it up-to-date. You should also be careful when opening email attachments and avoiding websites that are known to be infected.

What does a computer virus actually do?
A computer virus is a type of malware that can infect a computer system without the user’s knowledge or permission. Viruses can cause a variety of problems, including:
-Disrupting the normal functioning of the computer
-Preventing the computer from booting up
-Damaging or deleting files
-Stealing or corrupting data
-Spreading to other computers on the network
There are many different types of computer viruses, and they can be very difficult to detect and remove. It is important to keep your computer up to date with the latest security patches and antivirus software, and to never open attachments or click links in emails from unknown sources.
What 3 things can a computer virus do?
There are many different types of computer viruses, but they all have the potential to do damage. Here are three of the most common things a virus can do:
1. Delete or corrupt data
A virus can delete or corrupt important files on your computer, rendering them unusable. This can cause serious problems for your business or personal life, and can be very costly to fix.
2. Slow down your computer
A virus can slow down your computer, making it run more slowly than usual. This can be very frustrating, especially if you need to use your computer for important tasks.
3. Install other malicious software
A virus can also install other malicious software on your computer, such as spyware or ransomware. This can damage your computer, steal your personal information, or lock you out of your files until you pay a ransom.
What causes computer virus?
A computer virus is a type of malicious software that, when executed, replicates itself by copying itself to other computer files or programs. It can affect your computer system in many ways, including corrupting or deleting data, or even rendering your computer inoperable.
There are many different ways that a computer virus can be introduced into your system. Some of the most common methods include:
• Downloading and installing software from unauthorized or compromised websites
• Opening infected email attachments
• Connecting infected USB drives to your computer
Once a computer virus is in your system, it can be very difficult to get rid of. Often, the only way to rid your computer of the virus is to reformat your hard drive and reinstall your operating system.
So, what causes computer viruses? In short, there are many different causes, but some of the most common include:
• Ignorance – Many people install software or open email attachments without knowing whether or not they are safe.
• Carelessness – People often connect infected USB drives to their computer or visit compromised websites without taking the necessary precautions to protect their system.
• Malicious Intent – Unfortunately, there are also people out there who create computer viruses on purpose, either for financial gain or to cause damage to others.
No matter how a computer virus is introduced into your system, it can be a serious threat to your privacy and data. It is important to be aware of the dangers of computer viruses and to take the necessary precautions to protect your computer.
How does the virus infect a computer?
In computing, a computer virus is a type of malicious software program that, when executed, replicates by infecting other computer programs and files. Viruses can range from a simple program that displays a message on the user’s screen, to a program that can delete files or even reformat the computer’s hard drive.
Viruses are typically spread by e-mail, or through infected files that are shared on file-sharing networks. Some viruses can also spread through bootable media, such as floppy disks, CD-ROMs, or USB flash drives.
When a computer is infected with a virus, the virus may be hidden away in the computer’s memory, or it may be present in one or more of the computer’s files. Some viruses will activate automatically when the infected computer is booted up, while others may require the user to take some specific action, such as opening an infected file.
There are a number of different ways that a computer can become infected with a virus. The most common way is through e-mail. E-mail viruses are commonly spread through infected attachments, or through links to infected websites. Viruses can also be spread through file-sharing networks, or through infected media, such as floppy disks, CD-ROMs, or USB flash drives.
Many viruses are designed to exploit vulnerabilities in the operating system or in popular software applications. When these vulnerabilities are discovered, the makers of the virus will release a new version of the virus that takes advantage of the vulnerability. This is why it is important for computer users to keep their software applications up-to-date.
How do I get rid of a virus?
When your computer is infected with a virus, it can be difficult to know what to do. This guide will teach you how to get rid of a virus and protect your computer from future infection.
The first step is to identify the virus. There are many different types of viruses, and each one requires a different approach to removal. You can use a free online virus scanner to identify the virus, or take your computer to a technician for assistance.
Once you have identified the virus, you can begin the process of removal. This process will vary depending on the type of virus, but typically involves running a series of scans and removing the infected files. It is important to be careful when removing infected files, as any mistakes can result in further damage to your computer.
In addition to removing the virus, it is important to take steps to protect your computer from future infection. You can do this by installing a reliable antivirus program and keeping your computer up to date. You should also be careful when clicking on links or opening attachments in email, as these can often be vectors for virus infection.
With a little knowledge and preparation, you can safely remove a virus from your computer and protect it from future infection.
How can we remove computer virus?
A computer virus is a type of malicious software that, when executed, replicates itself by modifying other computer programs or files. It can inflict damage to the computer system or to the data stored on it.
There are a number of ways to remove a computer virus. The most common approach is to use an anti-virus software program. This program scans the computer for viruses and removes them. It is important to keep the anti-virus software program up-to-date so that it can protect the computer against the latest viruses.
Another way to remove a computer virus is to use a virus removal tool. This is a program that is specifically designed to remove viruses. It is important to note that not all virus removal tools are effective against all viruses.
If the computer is infected with a particularly nasty virus, it may be necessary to reformat the hard drive and reinstall the operating system. Reformatting the hard drive will erase all of the data on it. It is important to back up the data before reformatting the hard drive.
It is also important to keep the computer up-to-date with the latest security patches. These patches fix vulnerabilities in the operating system and help to protect the computer from attacks by viruses and other malicious software.
How bad is a computer virus?
A computer virus is a type of malware that can cause major damage to your computer. It can affect your computer’s performance, steal your data, or even damage your hardware.
There are many different types of computer viruses, and they can vary in severity. Some viruses are relatively harmless, while others can cause a great deal of damage. Some viruses can even delete or encrypt your data, or disable your computer altogether.
If your computer is infected with a virus, it’s important to take action right away. You can try to remove the virus yourself, or you can use a virus removal tool. If you’re not sure how to remove the virus, or if the virus is causing major damage, you may need to take your computer to a technician.
