Best Antivirus for Mac in 2026 (Compared and Ranked)

Lab results for Mac antivirus are now so close that price and extras decide the pick. In AV-Comparatives' June 2026 Mac test, all nine products earned the Approved Mac Security award with zero false alarms, and in AV-TEST's first-quarter 2026 macOS test, eight of ten consumer products scored the full 18 of 18 points. The practical answer: Bitdefender Antivirus for Mac is the paid default for one to three Macs (USD 24.99 for the first year on one Mac, as of October 31, 2026), Avast One Free or AVG AntiVirus Free is the free option, and Intego ONE suits Mac-only households that want a firewall in the same suite, with the lowest Mac malware score of the group in AV-Comparatives (96.7 percent).

Best Antivirus for Mac in 2026: Quick Picks

The same ranking logic applies to a Mac used for work: the cheapest product that sits at the top of both lab tables is the right default, and a paid suite earns its price only through extras you will actually use (firewall, VPN, backup protection, multi-device cover).

What macOS Already Does, and What Antivirus Adds

Apple states that macOS includes built-in antivirus technology called XProtect, which does signature-based detection and removal of malware, and that Apple updates those signatures automatically, independent of system updates, with macOS checking for updates daily by default (Apple Platform Security guide). Apple also runs Notarization, a malware scanning service for apps distributed outside the App Store, and Gatekeeper uses that information to block launch of flagged files.

That baseline is why Mac antivirus is less urgent than Windows antivirus, but the labs still find a large pool of Mac malware to test against: AV-Comparatives used 1,500 Mac malware samples and 1,500 Mac potentially unwanted application (PUA) samples in 2026, and AV-TEST used over 400 recent macOS malware samples. A third-party product adds extras on top of Apple's tools: a firewall with outbound rules, web and phishing filtering, backup protection, and (in some suites) a VPN. Whether those are worth paying for depends on how the Mac is used, which is the logic behind the picks above.

Lab Results Side by Side

AV-Comparatives Mac Security Test, June 2026

Test period April to May 2026 on macOS Tahoe, with 1,500 Mac malware, 1,500 Mac PUA and 100 Windows malware samples. No product produced a false positive, and every product earned Approved Mac Security (full report).

*AV-Comparatives treats Windows-malware detection on a Mac as discretionary, so CrowdStrike's 0 percent there is not a miss on Mac threats. The report also notes that its Mac sample size is very small compared with Windows, and that no Mac security product is ideal for every user. Avast One Free was tested in its free version at Avast's request, and Avast, AVG and Norton are Gen Digital products that share the Avast engine, so their near-identical scores are one engine measured three times.

AV-TEST Home macOS Test, Q1 2026

Run on macOS Tahoe 26.3 and published June 2, 2026, each product can earn up to 18 points (protection, performance and usability, 6 each). AV-TEST used over 400 recent macOS malware samples, over 40,000 clean files and nearly 200 harmless applications to check for false alarms; none of the 14 products tested, consumer and business, produced one (results, test write-up).

AV-TEST attributes every point deduction to the malware detection category: Trend Micro detected 98.5 percent of samples and Avira 97.5 percent. Both still passed the 10-point certification threshold, but they trail the eight products at full marks.

Price and Plan Comparison

Two billing traps are visible even without every price. First, Bitdefender's and Intego's own pages both warn that renewal pricing can differ from the first purchase, so the first-year figure is not the cost of owning the product. Second, Intego's listed price of USD 74.99 for two years works out to about USD 37.50 per year, while Bitdefender's one-Mac one-year plan is USD 24.99; the cheaper headline is not always the cheaper product once the term length is compared.

Feature Matrix

"Not confirmed" means the vendor pages and lab reports read for this guide did not state it, not that the feature is absent.

The Picks in Detail

1. Bitdefender Antivirus for Mac: best paid default

Best for: one to three Macs, or a mixed household that wants one vendor across devices. Price: USD 24.99 for the first year on one Mac, USD 29.99 on three Macs (1-year plans, as of October 31, 2026).

Bitdefender scored 18 of 18 in AV-TEST and 99.0 percent on Mac malware with 94 percent on PUA in AV-Comparatives, with no false positives. It is the lowest verified-price product that sits at the top of the AV-TEST table, and its page lists Time Machine Protection, aimed at malware that tries to encrypt or destroy backups, plus a browser extension that scans links. Its trade-offs: the Mac detection figures are a few tenths of a point behind the Gen Digital engine in AV-Comparatives, and the renewal price is not stated on the purchase page, so check the amount before the first renewal. Check current Bitdefender for Mac pricing.

2. Avast One Free and AVG AntiVirus Free: best free option

Best for: a single Mac where the goal is real-time protection without a subscription. Price: free.

The free versions posted 99.9 percent Mac malware detection and 95 percent PUA detection in AV-Comparatives, and Avast Security and AVG Antivirus each scored 18 of 18 in AV-TEST. AV-Comparatives' reviewers flag the cost of free: frequent upsell prompts (including a 60-day paid-trial offer after an initial decline), persistent alerts, and admin rights required to disable protection or restore quarantined items. Expect to be asked to upgrade.

3. Intego ONE: best Mac-only suite

Best for: households that run only Macs and want antivirus and a firewall in the same product. Price: Essential, one Mac, two years: USD 56.24 in a limited-time offer on October 31, 2026, with USD 74.99 per two years listed and shown as the renewal price.

Intego scored 18 of 18 in AV-TEST, and its plan ladder is clear: Essential is antivirus plus firewall, Advanced adds SmartClean, and Complete adds a VPN and an iPhone app. The weak point is detection: 96.7 percent of Mac malware in AV-Comparatives' 2026 test, the lowest of the consumer products, and 97.1 percent in the 2025 test. Terms matter too: the Essential checkout auto-renews every two years and says the renewal price is subject to change with advance notice. Check current Intego ONE pricing.

4. Norton: top scores, price unverified

Norton 360 scored 18 of 18 in AV-TEST and Norton AntiVirus Plus posted 99.9 percent Mac malware detection in AV-Comparatives. Norton's US pages could not be read in a plain fetch on this pass, so no price is quoted. Compare the first-year price and the renewal price on Norton's Mac page before buying, because intro-price renewals are where suite costs diverge.

5. ESET HOME Security: top scores for mixed-device households

ESET scored 18 of 18 in AV-TEST (ESET Security Ultimate 9.0) and 99.9 percent Mac malware detection in AV-Comparatives (ESET HOME Security Essential 9.0). ESET says its HOME Security plans secure Windows, macOS and Android devices under one subscription, with 30-day returns. AV-Comparatives notes that external-storage scanning and device control are off by default and recommends enabling PUA detection during setup. See the plans on ESET's protection plans page.

6. Malwarebytes: a cleanup tool, not a lab-tested suite

Malwarebytes describes its free product as a cleanup tool for devices that are already infected, and Premium as the version that runs continuously to stop attacks first, with a 60-day money-back guarantee. Neither AV-TEST's nor AV-Comparatives' 2026 consumer Mac lists include it, so there is no recent independent detection score to cite here. It is a reasonable second-opinion scanner, not a lab-verified primary product.

Kaspersky: scores 100 percent, but not available to U.S. buyers

Kaspersky Premium posted 100 percent Mac malware detection in AV-Comparatives and 18 of 18 in AV-TEST. For buyers in the United States it is not an option: the Commerce Department's Bureau of Industry and Security announced on June 20, 2024 that Kaspersky Lab, Inc. is barred from providing anti-virus software in the United States, with signature updates ending after September 29, 2024 (BIS announcement).

How to Choose Mac Antivirus Software

Do not stack two real-time products

Run one real-time engine at a time. A free on-demand scanner used occasionally is a different case: Malwarebytes Free, for example, is positioned as a cleanup tool rather than a continuous shield.

Check the term, not just the headline price

Divide the price by the number of years: Intego's USD 74.99 covers two years and Bitdefender's USD 24.99 covers one. Then find the renewal price on the checkout page before entering payment details.

Pair antivirus with the rest of the stack

Antivirus covers files and links. It does not replace automatic macOS updates, a password manager or a VPN on public Wi-Fi. See the guides to password managers and the best VPN for small business.

Frequently Asked Questions

Do Macs need antivirus software?

Macs ship with built-in protection: Apple says XProtect provides signature-based detection and removal of malware and is updated automatically, independent of system updates. A third-party product adds a firewall, web filtering and other extras, and in the 2026 labs every consumer product caught at least 96.7 percent of Mac malware samples. Whether the extras are worth paying for depends on how the Mac is used.

What is the best free antivirus for Mac?

Avast One Free and AVG AntiVirus Free posted 99.9 percent Mac malware detection and 95 percent PUA detection in AV-Comparatives' June 2026 test, with no false positives. The reviewers report frequent upsell prompts and persistent alerts in the free version.

Which Mac antivirus has the best lab scores?

Eight consumer products scored 18 of 18 in AV-TEST's Q1 2026 macOS test: Avast, AVG, Bitdefender, ESET, F-Secure, Intego, Kaspersky and Norton. In AV-Comparatives' 2026 test Kaspersky led at 100 percent of Mac malware, followed by Avast, AVG, ESET and Norton at 99.9 percent.

Will antivirus slow down a Mac?

Not measurably in the 2026 tests. AV-Comparatives reports no meaningful performance impact from any reviewed product, and all ten consumer products earned 6 of 6 for performance in AV-TEST.

How much does Bitdefender Antivirus for Mac cost?

As of October 31, 2026, Bitdefender lists USD 24.99 for one Mac on a 1-year plan and USD 29.99 for three Macs, both described as first-year prices. Two-year plans are USD 69.99 for one Mac and USD 89.99 for three Macs, and the page notes that renewal pricing may be higher.

Is Intego worth it compared with free options?

Intego ONE Essential bundles antivirus with a firewall and scored 18 of 18 in AV-TEST, but it posted 96.7 percent Mac malware detection in AV-Comparatives' 2026 test against 99.9 percent for the free Avast and AVG products. It is worth considering only if you want the firewall and a Mac-only vendor.

Is Malwarebytes enough protection for a Mac?

Malwarebytes describes its free version as a cleanup tool for devices that are already infected, and Premium as the continuous protection tier. Neither lab included Malwarebytes in its 2026 consumer Mac results, so there is no independent detection score to compare.

Can U.S. buyers still purchase Kaspersky for Mac?

No. The Commerce Department announced on June 20, 2024 that Kaspersky Lab, Inc. is barred from providing anti-virus software in the United States, and Kaspersky's signature updates to existing U.S. customers ended after September 29, 2024.

Which One Should You Buy?

For a single Mac and a small budget, Bitdefender Antivirus for Mac at USD 24.99 for the first year is the lowest-cost product verified at the top of the AV-TEST table, and the free Avast or AVG products are close behind in AV-Comparatives at no cost. For a Mac-only household that wants a firewall in the same suite, Intego ONE is the fit, with the lab caveat above. For mixed Windows and Mac households, price the cross-platform plans from Bitdefender, ESET and Norton against each other, including renewal.
