What is the best virus scanner for Mac?
[1] https://www.av-comparatives.org/about-us/ AV-Comparatives is an independent organization offering systematic testing that checks whether security software, such as PC/Mac-based antivirus products and mobile security solutions, lives up to its promises. Using one of the largest sample collections worldwide, it creates a real-world environment for truly accurate testing. AV-Comparatives offers freely accessible results to individuals, news organizations and scientific institutions. Certification by AV-Comparatives provides an official seal of approval for software performance which is globally recognized.
Currently, AV-Comparatives' Real-World Protection Test is the most comprehensive and complex test available when it comes to evaluating the real-life protection capabilities of antivirus software. Put simply, the test framework replicates the scenario of an everyday user in an everyday online environment – the typical situation that most of us experience when using a computer with an Internet connection.
AV-Comparatives works closely with several academic institutions, especially the University of Innsbruck’s Department of Computer Science, to provide scientific testing methods.

If you want additional protection, I believe your best option is Avast:

Snarkiness aside, you don't need an antivirus on your Mac. As long as you run as a non-admin user, enable a firmware password, and stay away from Adobe Flash, you are golden.
Since you do need to install stuff sometimes, I'm not sure what a power user who's careful about password prompts would gain from routinely running as a non-admin.
And keep your system up to date of course (done by default, or at least the notifications to that effect). And don't use the admin user on a day to day basis (done by default).
