Computers are useful tools. We use them for school and work. But computers can get sick. They can get computer viruses. A virus is a bad program. It can steal your files or make your computer slow. You must protect your device. 🛡️
How Viruses Infect Computers
Hackers write viruses to do bad things. They hide them in email attachments. They also put them on shady download websites. If you click a bad link the virus downloads automatically. You might not even know it is there.
Here is how a computer gets infected:
[User Clicks Bad Link] ==> [Virus Downloads in Secret] ==> [System Files Corrupted]
This is why you must be careful. Do not click links from strangers.
How Antivirus Software Protects You
Antivirus software is like a shield. It scans your files daily. It looks for known virus signatures. If it finds a bad file it deletes it. It also blocks dangerous websites before you open them.

| System Update | Downloads new virus definitions | Protects against new hacks |
| Quarantine | Locks suspicious files in a vault | Prevents virus from spreading |
