Norton Security for Mac review: Testing explained

Testing Mac Antivirus software is a split into four major sections. The first test is a regular malware detection test. Next, we measure the load AV software puts on a Mac’s performance. This is followed by a false positives test to make sure non-harmful files aren’t flagged as dangerous. The test is concluded with a Potentially Unwanted Applications test – PUAs are programs with excessive advertising, messaging or privacy policies. See for more information.


Protection & Performance


Norton Security 7.5 is one of a handful of Mac AV apps that posted a perfect 100% detection score during testing. Detected all 514 malware samples the test threw at it.

Tests were performed on an iMac running Sierra 10.12.6. During testing, we left internal MacOS protection running.

Norton Security also scored well in the system load test. Adding just one second to the base test speed. This is the best score measured in the 2018 Mac Antivirus test. Kaspersky Lab Internet Security for Mac is Norton’s closest rival, posting an equal score in malware detection while only added 1.5% to a Mac’s system load.

Some previous Mac Antivirus programs added an unacceptable load to system performance. To test the load of modern Mac AVs testers copied a combination of files measuring 27.28 GB to the Macs. A true performance time (203 seconds) was recorded without any Mac Antivirus software running. The test was then repeated with each Mac Antivirus package. Norton Security for Mac posted an impressive system load time of 204 seconds.

Potentially Unwanted Applications & False Positives


Norton detected over 98% of the potentially unwanted applications it was subjected to. This score is on a par with all 8 of its competitors.

PUAs (Potentially Unwanted Applications) are not technically harmful programs. However, users may not want them on their Macs due to excessive levels of advertising, messaging or dubious privacy policies.

The False Positives test was another perfect result for Norton. During testing, it successfully identified 100% of the harmful applications while allowing all safe applications through.

The aim of this test is to ensure AV software doesn’t incorrectly identify clean files as malware. During the test security packages has to test hundreds of clean program files and also monitor the installation of 35+ applications.
