How does a computer get a virus? Computers have become an integral part of our lives. We use them for work, entertainment, communication, and so much more. However, with the increased use of computers comes the risk of viruses and malware. In this article, we will explore how a computer gets a virus and what you can do to protect yourself.

What is a computer virus?

A computer virus is a type of malicious software that can replicate itself and spread to other computers. Once a virus infects your computer, it can cause various problems, such as data loss, system crashes, and identity theft.

How do viruses spread?

Viruses can spread through various means, including:

1. Email attachments

One common way that viruses spread is through email attachments. Hackers often send emails with attachments that contain viruses. When the user downloads the attachment and opens it, the virus is activated.

2. Downloaded software

Downloading software from the internet can also be a source of viruses. Hackers can embed viruses into legitimate-looking software, and when the user downloads and installs it, the virus is installed as well.

3. Infected websites

Visiting infected websites can also lead to virus infections. Hackers can create websites that contain viruses, and when the user visits the site, the virus is downloaded onto their computer.

4. Infected devices

Viruses can also spread through infected devices, such as USB drives. If a virus-infected USB drive is connected to your computer, the virus can spread to your computer.
