What is Antivirus Software?

Before diving into the top free antivirus software, it’s important to understand what antivirus software is and how it works. Antivirus software is a program designed to detect, prevent, and remove malware (malicious software) from your computer or mobile device. The types of malware it protects against include viruses, worms, trojans, spyware, adware, ransomware, and more.

How Does Antivirus Software Work?

  • Real-Time Protection: Most antivirus programs offer real-time protection, which means they continuously monitor your system for suspicious activity or files.
  • Scanning and Detection: Antivirus software scans files and programs to detect malware signatures or unusual behavior that could indicate a threat.
  • Malware Removal: Once a threat is detected, antivirus software will either quarantine or remove it entirely, depending on the level of risk.
  • Updates: Frequent updates ensure the antivirus software can recognize the latest malware and adapt to new threats.

Now that you understand what antivirus software is and how it works, let’s explore the top five free antivirus options available for the coming years.
