What is a Computer Virus?
A computer virus is like a cold for your computer - it's a piece of harmful software (a program) that can make your computer sick. Just like a cold can spread from person to person, a computer virus can spread from computer to computer.
How Do Viruses Work?
Think of a computer virus like a burglar who breaks into your house:
- They get in without you knowing (through an email, website, or program)
- They look around and find your valuable things (your files, passwords, photos)
- They might steal things (your personal information)
- They might break things (delete files or slow down your computer)
- They might tell their friends how to get in too (spread to other computers)
How Do Viruses Get on Your Computer?
Viruses can get onto your computer in several ways:
1. Email Attachments
Someone might send you an email with a file attached (like a document or photo). If you open it, the virus gets onto your computer.
How to stay safe: Never open attachments from people you don't know. Even if it's from someone you know, if it seems suspicious, check with them first.
2. Websites
Some websites try to put viruses on your computer when you visit them. These are usually websites you shouldn't be on anyway (like illegal download sites).
How to stay safe: Stick to websites you know and trust. If a website looks suspicious, don't visit it.
3. Downloads
Downloading programs or files from the internet can bring viruses with them, especially if you download from untrustworthy websites.
How to stay safe: Only download from official websites (like the App Store, Google Play, or the program's official website).
4. USB Sticks or Memory Cards
If someone gives you a USB stick or memory card, it might have a virus on it.
How to stay safe: Only use USB sticks from people you trust. If you're not sure, scan it with antivirus software first.
What Do Viruses Do?
Viruses can do different things:
- Slow down your computer: They use your computer's power, making everything slower
- Delete your files: They might delete your photos, documents, or other important files
- Steal your information: They might steal your passwords, bank details, or personal information
- Show you pop-ups: They might show lots of annoying pop-up adverts
- Lock your files: Some viruses lock your files and demand money to unlock them (this is called ransomware)
- Use your computer for bad things: They might use your computer to send spam emails or attack other computers
How to Protect Yourself
The good news is, protecting yourself from viruses is easier than you might think:
1. Use Antivirus Software
Antivirus software is like a security guard for your computer. It watches for viruses and stops them before they can get in.
Good news: If you have WiseGuys device protection, we provide free antivirus software! It's included in your plan.
2. Keep Everything Updated
Updates fix security problems that viruses might use to get in. Make sure your computer, phone, and programs are all up to date.
3. Be Careful with Emails
Don't open emails or attachments from people you don't know. If an email seems suspicious (like it's asking for your password or bank details), delete it.
4. Be Careful with Websites
Stick to websites you know and trust. If a website looks suspicious or asks you to download something, leave it.
5. Use Strong Passwords
Strong passwords make it harder for viruses (and hackers) to get into your accounts. Learn how to create strong passwords.
How Do I Know If I Have a Virus?
Signs that you might have a virus:
- Your computer is much slower than usual
- Lots of pop-up adverts appear
- Programs open and close on their own
