What Is Antivirus Software and Why You Need It

1. What Is Antivirus Software?

Antivirus software is your digital bodyguard. It protects your computer, smartphone, or tablet from harmful programs called malware — including viruses, spyware, ransomware, and more. While you work, browse, or watch a video, it runs in the background to keep your data and privacy safe.

2. What Does It Protect You From?

Modern antivirus programs guard you against:

• Viruses – malicious code that spreads and corrupts files

• Spyware – secretly tracks your activities and steals sensitive data

• Ransomware – locks your files and demands payment to restore them

• Trojans – fake software that secretly installs malware

• Phishing attacks – fake websites or emails that try to steal your passwords

Without protection, even one wrong click can open the door to serious damage.

3. What Can Happen Without Antivirus?

You may not notice anything at first — and that's the danger.

• Hackers could steal your login details or banking information

• You could lose important files like photos or documents

• Your device could be turned into a tool for spreading spam or viruses

• Criminals might lock your data and demand payment to get it back

Antivirus software stops threats before they take over.

4. How Does Antivirus Work?

Antivirus tools use advanced technology to detect and stop threats. They:

• Scan new files and apps in real-time

• Compare suspicious files to known threat databases

• Analyze behavior patterns to catch new and unknown malware

• Isolate (quarantine) or delete harmful files automatically

• Keep themselves updated to fight the latest attacks

The best antivirus tools run quietly, but react fast when danger appears.
