How do computer viruses spread?
A computer virus is a code or program that has the ability to copy itself and spread itself to other computers. The term “virus” is used because this code or program has the potential to do harm to the computer it infects. There are many ways that a virus can spread, including email attachments, infected websites, and shared network drives.
Email attachments are the most common method of spreading a virus. This is because email is such a commonly used method of communication and because it is so easy to send an email attachment. When a person receives an email with an attachment, they may not think twice about opening it, especially if they know the sender. Once the attachment is opened, the virus will install itself on the computer and start replicating.
Infected websites are another common method of spreading a virus. Websites can become infected with a virus if they host malicious code or if they have been hacked. When a person visits an infected website, the virus can install itself on their computer. This is why it is important to be careful when visiting websites and to only visit websites that you trust.
Shared network drives can also be a source of infection. If a computer on a network is infected with a virus, the virus can spread to other computers on the same network. This is why it is important to have antivirus software installed on all computers on a network.
There are many other ways that a virus can spread, but these are the most common. It is important to be careful when using email, visiting websites, and using shared network drives. If you think that your computer may be infected with a virus, you should run a virus scan as soon as possible.
What are some of the most common computer viruses?
There are many different types of computer viruses, but some of the most common ones include the following:
1. The boot sector virus is one of the most common types of viruses. This virus infects the boot sector of a computer’s hard drive, making it difficult or impossible for the computer to start up.
2. Another common type of virus is the file-infecting virus. This virus attaches itself to executable files, making it difficult to run programs or open files.
3. Another common virus is the macro virus. This virus is often spread through email attachments, and can be used to remotely control a computer.
4. Another type of virus that is becoming more common is the ransomware virus. This virus encrypts a computer’s files, making them inaccessible unless a ransom is paid.
5. Finally, there is the spyware virus. This virus collects information about a computer’s user, such as their passwords and browsing habits.
