Here’s a detailed explanation of computer malware:
🦠 What Is Malware?
Malware (short for malicious software) is any software intentionally designed to:
- Disrupt or damage computer systems
- Steal sensitive data
- Gain unauthorized access
- Spy on user activity
- Extort money or resources
It can infect computers, servers, mobile devices, and networks—posing serious risks to individuals, businesses, and governments.
🧬 Types of Malware
| Type | Description |
|---|---|
| Virus | Attaches to files and spreads when they’re opened |
| Worm | Self-replicates and spreads across networks without user action |
| Trojan Horse | Disguises itself as legitimate software to trick users into installing it |
| Ransomware | Encrypts files and demands payment for their release |
| Spyware | Secretly monitors user activity and steals data |
| Adware | Displays unwanted ads and may track browsing behavior |
| Rootkit | Hides deep in the system to allow persistent access |
| Botnet | Turns infected devices into “zombies” for coordinated attacks |
🧠 How Malware Works
Malware typically enters a system through:
- Phishing emails
- Malicious websites or downloads
- Infected USB drives
- Software vulnerabilities
Once inside, it may:
- Hijack system functions
- Steal or encrypt data
- Install additional malware
- Use your device for attacks (e.g., DDoS or crypto mining)
⚠️ Signs of Infection
- Sluggish performance
- Frequent crashes or freezes
- Unusual pop-ups or ads
- Mysterious loss of disk space
- Unauthorized access or changes
🛡️ How to Protect Against Malware

- Keep your OS and apps updated
- Avoid clicking suspicious links or attachments
- Enable firewalls and multi-factor authentication
