Understanding Computer Viruses

What is a computer virus?

A computer virus is a malicious software program that can infect your computer and cause various problems. It is designed to replicate itself and spread to other computers, often without the user’s knowledge or consent. Viruses can be transmitted through email attachments, infected websites, or by downloading infected files. Once a virus infects your computer, it can damage files, steal personal information, and even render your computer unusable.

How do computer viruses spread?

Computer viruses can spread through various means, posing a significant threat to your system’s security. Understanding how viruses spread is crucial in implementing effective preventive measures. Here are the three primary ways computer viruses can spread:
