Windows remains the world's most popular operating system, powering billions of PCs. But with rising cyber threats like ransomware, phishing, and zero-day exploits, built-in Windows Defender alone often falls short. Our extensive testing of over 40 antivirus programs for Windows 10 and 11 shows that premium software delivers 98-100% malware detection rates, compared to Defender's 92% in independent labs.
In 2024, the best antivirus goes beyond detection: it includes real-time web protection, password managers, and minimal CPU usage (under 5% during scans). Whether you're gaming, working remotely, or browsing, these tools keep your data safe without interrupting your day.
