Why Antivirus Still Matters in 2026
Some people believe that built-in protections are enough. While tools like Microsoft Defender have improved significantly, independent security labs still show that dedicated antivirus software detects and blocks more advanced threats.
For example, a 2025 AV-Test report found that premium antivirus solutions detected over 99% of zero-day attacks, compared to lower rates for free options. That difference can mean the safety of your private data or falling victim to ransomware.
