Best Mac Antivirus of 2019 – Top Virus Protection Software for Macs


After evaluating eight free and paid antivirus products, we’ve chosen Kaspersky Internet Security for Mac ($40 per year) as the best antivirus for Mac. It had a nearly invisible impact on system performance, and it caught all malware.

Avast Free Mac Security is our favorite free option, as it provided nearly perfect malware protection and an easy-to-use interface with an imperceptible performance hit.

You do need an antivirus program on your Mac. Recent years have seen more Mac malware and adware than ever before, from Trojans to targeted attacks, supply-chain attacks like the XcodeGhost attack and even encrypting ransomware.

Latest Security Alerts and Threats

— Anyone with access to your private Instragram or Facebook posts can easily copy the content of the posts and pass it along to someone else, BuzzFeed News found. ADVICE: This isn’t much of a hack, since it just involves viewing the source code of a web page, but it’s worth keeping in mind that nothing you put online is ever truly private.

— Nearly 200 million records pertaining to prospective car buyers was found unprotected online. The records held names, addresses, phone numbers, email addresses, IP addresses and other sensitive information. ADVICE: It’s not clear if any bad guys found the database before it went behind a password, but if you’ve recently inquired about buying a car, make sure your email spam filter is working properly.

— Hundreds of thousands of cheap GPS tracking devices for pets, cars and children have a default password of “123456” that lets hackers take remote control easily, security firm Avast reported. ADVICE: Don’t buy GPS tracking devices from off-brands you’ve never heard of. Stick to better-known manufacturers.

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 Buy

Perfect malware detection

Minimal system impact

Parental controls

Kaspersky Internet Security is the best antivirus for Macs because it offers both the lowest system impact and some of the best malware-detection rates recorded. It even provides extra security features, including parental controls and options to lock down your webcam and stop websites from tracking your browsing activity. If you’re willing to pay to protect your Mac from malware, Kaspersky Internet Security is the best option available. 

Best Free Mac Antivirus

Reasons to Buy

Free

Excellent malware protection

Nearly no system impact in background

Password manager included

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

Perfect malware detection

Ransomware protection

Elegant modern design

Parental controls

Reasons to Avoid

Highest passive system impact

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

Excellent malware detection

Reasons to Avoid

Expensive

Noticeable system impact

Lack of special features

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

Excellent malware protection

Free

Easy-to-use design

Reasons to Avoid

No special features

Comparatively high background impact

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

Free

Remote manageability

Parental controls

Low system impact

Reasons to Avoid

Competitors beat it on malware detection

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

Free

Solid malware protection

Reasons to Avoid

Notable system impact during full scans

Avira Free Antivirus for Mac

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

Unlimited accounts

Familiar user interface

Reasons to Avoid

Sparse special features for paid service

Unproven detection rates

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.
