Our favorite free option is Avast Security for Mac, which has nearly perfect malware protection and an easy-to-use interface. Norton catches all Mac and Windows malware in lab tests, has 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 an unlimited VPN and password manager. It had a nearly invisible impact on system performance in our own tests, caught all Mac and Windows malware in lab tests, rolls back files encrypted by ransomware, and hardens your web browser against online attacks. We think Bitdefender Antivirus for Mac is the best Mac antivirus program you can buy.

Its malware protection is top-notch, its system impact is minimal and it’s dialed back the annoying ads upselling you to a paid version. View Deal What is the best Mac antivirus program? Avast offers the best free Mac antivirusĪvast Security for Mac may cost nothing, but it doesn’t cut corners.
