What is Antivirus software

Antivirus software is a program designed to detect, prevent, and remove malicious software, or malware, from computers and other devices. Its primary role is to protect your system from various threats such as viruses, worms, trojans, ransomware, spyware, and adware.

Here’s how antivirus software typically works:

  1. Scanning: The software scans files and programs on your device to identify any potential threats. This can be done through:
    • On-Demand Scanning: When you manually start a scan.
    • Scheduled Scanning: Automated scans that run at specified times.
    • Real-Time Scanning: Continuous monitoring of your device for any suspicious activity.
  2. Virus Definition Updates: Antivirus software relies on a database of known malware signatures to identify threats. This database needs to be regularly updated to recognize new threats as they emerge. Most antivirus programs update their virus definitions automatically.
  3. Heuristic Analysis: This method involves analyzing the behavior of programs to detect new, unknown viruses or variations of known ones. It looks for suspicious activities or patterns that could indicate malware.
  4. Quarantine and Removal: When the software detects malware, it often places the infected files into quarantine, isolating them from the rest of your system to prevent further damage. You can then choose to delete or attempt to repair the files.
  5. Firewalls and Additional Features: Many antivirus programs come with additional security features such as firewalls, which monitor and control incoming and outgoing network traffic, and tools for protecting against phishing attacks, securing your internet browsing, and more.

Using antivirus software is a key component of a comprehensive cybersecurity strategy. It helps safeguard your personal information, prevents data loss, and keeps your system running smoothly.
