There’s not much wrong with Trend Micro Antivirus for Mac, apart from a rather heavy system-performance impact during full scans. It offers 300MB of daily VPN usage, but its password manager and parental controls also are limited unless you pay more. Kaspersky Internet Security for Mac has perfect malware-detection scores, webcam protection, and a hardened browser. Its system-performance impact is far, but it once was, and it not nags you to upgrade to paid Avast products. Our favorite free option is Avast Security for Mac, with nearly perfect malware protection and an easy-to-use interface. Norton catches all Mac and Windows malware in lab tests, features a very small system-performance impact, and includes LifeLock dark-web monitoring. It also offers 200MB of VPN data daily, although that’s just a tease for the unlimited VPN service.Ĭlose behind is Norton 360 Standard, which has even better malware detection plus a vast VPN and password manager. It had an almost invisible impact on system performance in our tests, caught all Mac and Windows malware in lab tests, rolls back files encrypted by ransomware, and hardens your browser against online attacks.
