What is the best antivirus for Mac?
Intego Mac Internet Security is the best Mac-specific choice: built exclusively for macOS for decades, with the deepest Mac malware knowledge. Bitdefender offers the best cross-platform option for mixed households, and Norton 360 the strongest bundle on Mac.
Mac security software is a different discipline: the threats are mostly adware, fake cleaners, and infostealers rather than classic viruses, and software that fights macOS instead of working with it gets abandoned by users fast. Intego has done nothing but Mac security since the nineties; VirusBarrier and NetBarrier feel native, catch Mac-specific threats first, and respect the system.
For households with Windows PCs and Android phones alongside the Mac, a cross-platform suite is more practical: Bitdefender's Mac app delivers the same top-shelf engine with ransomware protection and web filtering, under one subscription for every device. Norton 360 brings its VPN and backup along to macOS as well.
Whatever you pick, keep perspective: on the Mac, the built-in protections plus careful installation habits carry more of the load than on Windows. The paid product earns its place through web protection (where most Mac trouble starts), faster detection of new adware campaigns, and coverage for the rest of your devices. And as on every platform: scary popups about your infected Mac are the infection.
