Introduction
In 2025, cyber threats are more advanced than ever. From ransomware and phishing scams to AI-powered malware, both Windows and Mac users need strong protection. While built-in security tools like Windows Defender and macOS XProtect have improved, they are not always enough against sophisticated attacks.
In this guide, we’ll explore whether you still need antivirus software in 2025, what features to look for, and the best antivirus solutions for Windows and Mac users.
Do You Still Need Antivirus in 2025?
Some users believe that built-in protections are enough. It’s true that:
Windows Defender has become very effective for everyday users.
macOS XProtect silently scans for known malware.
However, threats are evolving:
Ransomware can lock your files and demand payment.
Phishing attacks trick users into giving away credentials.
Zero-day exploits bypass built-in protection.
If you store sensitive data, shop online, or use your device for work, investing in a reliable antivirus is still highly recommended.
