How We Tested

To find the best antivirus for Mac desktops and laptops, we evaluate ease of use, interface and performance impact, we installed each AV program on the same Late 2013 MacBook Pro with Retina Display running macOS 10.12 Sierra. It was powered by a 2.6-GHz Intel Core i7 processor and had 8GB of RAM and 70GB of data stored on a 512GB SSD.

We conducted our own tests in July and August 2017 based on how much each antivirus product affected our laptop's performance. To do this, we used our custom OpenOffice benchmark, which matches 20,000 names and addresses in a spreadsheet. We measured how long it took to run a quick scan and a full scan while the laptop crunched numbers in the background.

We assessed how easy each program was to use and the number of useful extra features it offered (including free add-on software). To gauge how effective each package was at stopping malware, we used the results of evaluations conducted in May 2017 by AV-TEST, a well-regarded independent product-testing lab in Germany, and results from other tests conducted in July 2017 by AV-Comparatives, a similarly well-respected firm in Austria.

Reasons to Avoid

Best Free Mac Antivirus

Avast Free Mac Security

Reasons to Buy
Excellent malware protection
Password manager included
Reasons to Avoid

Avast Free Mac Security caught 99.9 percent of all malware, packs in a password manager, barely leaves a smudge on system impact and doesn't charge a dime. If only it caught 100 percent of malware, as Kaspersky did.

Bitdefender Antivirus for Mac

Reasons to Buy
Ransomware protection
Parental controls
Reasons to Avoid
Bitdefender Antivirus for Mac

Bitdefender Antivirus for Mac is one of only a few solutions we tested that offers perfect malware detection. Further, its modern, streamlined interface places on-demand scans front and center. Bitdefender has dropped from first place, though, because its system-impact scores don't match the flawless marks posted by Kaspersky.

Norton 360 Deluxe

Reasons to Buy
Reasons to Avoid
Noticeable system impact

Norton 360 Deluxe may offer excellent protection, but it charges more (after the first year) than its competitors do, without offering as many perks. Norton AntiVirus Plus offers similar protection for a single Mac, but with fewer perks. Still, both have always-on-call customer support.

AVG Antivirus for Mac

Reasons to Buy
Reasons to Avoid
Comparatively high background impact
AVG Antivirus for Mac

If you're looking for the best antivirus for Mac without having to pay, AVG AntiVirus for Mac is not too shabby, with its 99.9 percent detection rate and easy-to-use design. Unfortunately, other free competitors provide extras (Sophos with parental controls, Avast's password manager) that AVG does not.

Best for Families

Sophos Home

Reasons to Buy
Remote manageability
Low system impact
Reasons to Avoid

With Sophos Home for Mac's simple interface and low system-performance impact, you'll barely realize the program is shielding you until you need it. Anyone with young children at home will find Sophos' parental controls useful, as they allow for remote scans and checks, and let you block sites by category. Sophos even keeps a log of when users try to reach banned pages. This program's major drawback, though, is its lackluster malware-detection rate.

Avira Free Antivirus for Mac

Reasons to Buy
Solid malware protection
Reasons to Avoid

Once our favorite, Avira Free Antivirus for Mac is no longer the best antivirus for Mac. That's because it is a hair shy of perfection in its malware detection, and fell behind in system-performance testing, earning some of the higher performance impacts recorded.

McAfee Antivirus Plus

Reasons to Buy

Best Free Antivirus For Mac Os X El Capitan

Familiar user interface
Reasons to Avoid
Unproven detection rates
McAfee® AntiVirus Plus

Best Malware Antivirus For Mac

While McAfee's unlimited licenses mean you can support a whole family of Macs (and PCs and Android devices, too), this program's lack of special features (for a paid version) make it hard to recommend. Further, we don't have malware-detection testing scores for McAfee, so its protection powers are unproven.
