Introduction
Why Antivirus Software Still Matters in 2025
Cyber threats are evolving, and so should your digital defenses. While Windows has made some impressive strides with built-in tools like Microsoft Defender, relying on it alone is like locking your front door but leaving the windows wide open. In 2025, threats are more complex, persistent, and socially engineered. We’re not just talking about viruses anymore—ransomware, spyware, phishing scams, and zero-day attacks are at an all-time high.
Whether you’re a casual user, a business professional, or a hardcore gamer, one click on a malicious link or one download from a shady website can compromise your identity, files, and even your financial data. And with the rise of AI-generated malware, traditional detection methods just don’t cut it anymore.Best Antivirus Program for PC.
