What your child will learn

• Define what a computer virus is and how it can harm a computer system.

• List basic security measures to prevent virus infections.
• Understand the concept of malware and its impact on computer performance.

Understanding the concept

Imagine your computer is like your body, and a computer virus is like a tiny germ that can make your computer 'sick'. Just as germs can make you feel unwell, a computer virus is a small program designed to cause problems for your computer. These problems can range from slowing down your computer, making it difficult to open files, or even deleting important information. Viruses often spread without you knowing, much like a cold can spread when someone sneezes. They can hide in emails, on websites, or even on USB drives. The good news is that just like we use medicines to fight germs, there are special programs called 'antivirus' software that act like a doctor for your computer. This software helps to find and remove viruses, keeping your computer healthy and running smoothly. By learning about these viruses, we can understand how to protect our computers and stay safe when using them, similar to washing our hands to avoid catching a cold.

Tips for parents & teachers

• Encourage your child to read through the questions carefully before attempting to answer them.
• Discuss real-life examples of cyber security news or incidents to make the topic more relatable.
• After completing the worksheet, review the answers together and clarify any misconceptions.
• Use this worksheet as a springboard to talk about safe online practices at home.
• Consider doing a mini 'security check' on your home computer with your child to apply concepts learned.
