As a leading researcher in cyber security and malware protection, they bring a lot of expertise to the table. In April 2015, an independent antivirus software testing group called AV-TEST showed that Norton detected 100% of tested malware samples, ranking it among the most effective antivirus software for Mac. Norton’s Global Intelligence Network reports on threats around the world, helping them keep their virus definitions up to date. And deluxe and premium versions of the software also include parental control software and cloud backup capabilities. Possibly the most appealing factor of Symantec’s antivirus software is that it didn’t slow down AV-TEST’s computer during the performance test. Norton is the least system-resource-intensive antivirus package out there, and the fact that it’s still 100% effective makes it an easy choice for the top spot on this list.

($40 / year) BitDefender, like Norton, scored a 100% detection rate in the AV-TEST comparison (though it scored 99% on another test run by AV-Comparatives). The fact that BitDefender is constantly updating its malware definitions from the cloud, where much of the heavy lifting is done, means you can be confident that almost nothing will slip by your defenses. Moving processing to the cloud also prevents BitDefender from hogging your system resources; BitDefender was the second lightest client in AV-TEST’s results, only slowing down their Mac by a little bit.

BitDefender says that their Mac antivirus software was designed specifically to work well with OS X, and this could be the reason why it doesn’t place a big drain on Mac systems.

AV-TEST and AV-Comparatives both found that Kaspersky’s Internet Security for Mac detected 100% of threats—which isn’t surprising, considering that Kaspersky is one of the most well-known group of internet security researchers.

Kaspersky’s antivirus package comes with a few features that set it apart from many of its competitors, like network attack blocking and parental controls. This makes it a very versatile program that you can use to protect both your computer and your kids. It provides free automatic updates, protects from PC and Linux malware, and includes extra protection for your online monetary transactions. Falling right in the middle of the field, Kaspersky didn’t impress in the AV-TEST system resources performance test (though the system slow-down would likely be all but unnoticeable during regular usage). With the level of protection that it provides and the solid reputation backing the Kaspersky name, it’s still a viable choice for protecting your Mac from all of the threats out there. (Free) Although it wasn’t tested in either of the two recent reference tests by AV-TEST and AV-Comparatives, Comodo has been given a very positive review by AV-TEST in the past, which emphasized its negligible effect on system performance. Automatic updates combined with drag-and-drop file scanning and easy scheduling make this an antivirus package that anyone can use, regardless of their level of tech savviness.
