A computer virus is a type of malicious software that can infect a computer and cause a wide range of problems, from slowing down performance to stealing sensitive information. Viruses can spread quickly and easily through email attachments, software downloads, and other online sources. Once a virus infects a computer, it can replicate itself and spread to other computers on the same network. Some viruses are designed to be stealthy, making them difficult to detect and remove. To protect against computer viruses, it's important to use antivirus software and keep your operating system and other software up to date. It's also important to be cautious when downloading and opening files from the internet or unknown sources. You can use this template if you want to explain this idea to your audience.
