Why Antivirus Software Still Matters in 2025

Some users argue that built-in protections like Windows Security (Defender) or macOS XProtect are enough. While these tools are stronger than ever, hackers are also smarter.

Case Study: In 2024, a mid-sized company in Lagos was hit with ransomware that bypassed its default security tools. The company lost weeks of productivity and over $100,000 in recovery costs. A third-party antivirus with advanced threat detection could have prevented the attack.

• Ransomware protection
• Firewall & network monitoring
• Phishing detection

• Cross-platform support (Windows, macOS, Android, iOS)
