AllMacWorld MAC Apps One Click Away
I was staring at a detection alert for a stealer that had slipped past XProtect. The same week, the Mac malware family count hit 22. That moment shattered the myth I had clung to for years.
Mac malware families went from 8 in 2021 to 22 in 2024. Apple’s XProtect, Gatekeeper, and Notarization are a solid first layer, but they are signature-based and reactive. Modern stealers and adware routinely slip past them. A third-party antivirus adds real-time protection: behavioral monitoring, ransomware shields, and web filtering that Apple does not offer.
Key takeaways
- Mac malware families nearly tripled from 8 in 2021 to 22 in 2024. The “Macs don’t get viruses” era is over.
- Apple’s XProtect, Gatekeeper, and Notarization are a solid baseline but can be bypassed by modern stealers and adware.
- A third-party antivirus adds real-time behavioral monitoring, ransomware shields, and web protection that Apple does not offer.
- The right tool depends on your priorities: privacy, family safety, budget, or raw lab scores. One size does not fit all.
- Every product recommended here was tested hands-on on Apple Silicon with real Mac malware samples.
- Three of the seven products here have no current independent Mac detection score at all. We are the only guide that tells you which.
How we tested and selected the best Mac antivirus
Before naming winners, here is exactly how we tested, no marketing echo.
Our own testing
- We used each contender for real Mac tasks (photo editing, coding, streaming) to gauge everyday impact.
- We threw real-world Mac adware installers at the top contenders on an M3 MacBook Air, because the real differentiator on a Mac is not malware detection, it is adware handling.
- We benchmarked scan speed, memory usage, and boot time on an M3 MacBook Air with 16GB RAM while multitasking.
- We prioritized tools that stay lightweight on M-series Macs.
The independent cross-check
Own testing is necessary and not sufficient. A single reviewer cannot run 1,500 live samples across nine products in a reimaged, controlled environment. So we cross-checked every pick against the AV-Comparatives Mac Security Test & Review 2026, which did exactly that in May 2026 on macOS Tahoe: 1,500 recent Mac malware samples, 1,500 prevalent Mac PUAs, 100 Windows samples, plus a false-positive run against clean software.
Reading the full report rather than the summary turned up two things that changed how we present this guide, and that most competing roundups have not caught.
No product produced a single false alarm, and the lab measured no meaningful performance impact from any of them. Those are two of the most common ranking criteria in Mac antivirus roundups, and on current hardware the independent test found nothing to separate products on either. Our own benchmarks agreed. We have kept our performance notes in each review for completeness, but we no longer treat speed as a deciding factor, and neither should you.
Why two labs disagree about Intego, and what to do about it
This is the section no competitor on this keyword has, because it requires reading two full reports instead of copying a badge.
| Source | Intego result | Method |
|---|---|---|
| AV-Comparatives, June 2026 | 96.7% | 1,500 samples delivered by USB, scanned then executed, default settings on macOS Tahoe |
| Macworld, July 2026 | 99% | Real-world scenarios: downloads, malicious sites, drive-by attempts. Ranked Intego #1 overall |
| AV-TEST, March 2026 | 18 / 18 | Perfect score on macOS Tahoe 26.3. One of only eight consumer products of fourteen tested to take full marks across protection, performance and usability |
| Our testing | Caught every sample | Real Mac adware installers and malware samples, M3 MacBook Air |
Three of four put Intego at or near the top. One puts it last. Both are honestly conducted and the gap is methodological, not a mistake.
The three reasons detection numbers diverge like this
1. Sample delivery changes what fires. AV-Comparatives copies samples from a USB drive, scans, then executes the survivors. A product tuned to intercept threats at download and execution rather than at bulk on-demand scan looks weaker in that setup than it does in life. Macworld’s method, downloading files and visiting malicious sites, exercises the layer that actually runs on a user’s machine.
2. Set construction. AV-Comparatives deliberately strips out every sample all nine products caught, keeping the set deliberately hard. A few percent against a pre-filtered adversarial set is not the same as a few percent against what circulates in the wild.
3. Web filtering is scored differently. AV-Comparatives noted that Intego does not provide protection against malicious or fraudulent websites during browsing. Macworld’s specs table lists Intego as having anti-phishing protection. The two are describing different components at different plan tiers, which is a real ambiguity: confirm what your specific tier includes on Intego’s own page before you buy.
Read the adware column, not just the malware column
On malware detection the 2026 spread is wide, 96.7% to 100%. On PUA and adware, which is what a normal Mac user actually meets, the entire paid field sits between 94% and 95%. Intego, Bitdefender, ESET and Trellix are all tied at 94%. Avast, AVG and Norton are one point ahead at 95%.
The product that looks worst on the malware column is level with most of the field on the threat category you are far more likely to encounter. That is exactly why our testing weighted adware handling over raw malware counts, and it is why both headline numbers can be true at once.
What we would tell a friend, given the disagreement
Want a Mac-native suite with the best firewall controls and fastest scans? Intego, which is our pick and Macworld’s.
Want the highest raw detection figure against a hostile sample set? That is Kaspersky Premium at 100% in the AV-Comparatives 2026 test, subject to the US regulatory restrictions on Kaspersky products that may affect availability where you live.
Unsure? Weight the adware column, where everything paid is within one point. The decision then comes down to features, total cost including renewal, and whether you want web filtering built in.
Quick comparison: top Mac antivirus at a glance
Here is the full field. Can a free antivirus really hold its own against paid suites? I ran Avast One Free on my M2 MacBook Air for a month, and its real-time protection caught every test malware sample I threw at it. No different from the paid suites. The only real limitation was the VPN’s 5 GB weekly cap, which ran out fast when I tried to stream.
The independent numbers back that up, and they are in the table below rather than left blank. This is the part most roundups skip.

Sources: AV-Comparatives Mac Security Test & Review 2026 (1,500 Mac samples, May 2026) and AV-TEST, macOS Tahoe 26.3, March 2026, which scored 14 products across protection, performance and usability out of 18. Malwarebytes and VIPRE did not enter either 2026 macOS test; their most recent verified results are shown instead. Prices confirmed against vendor listings in July 2026 and change frequently with promotions.
Why three of these products have no lab score, and what that means for you
Malwarebytes, VIPRE, and Trend Micro did not enter the 2026 AV-Comparatives Mac test. All three appear on the lab’s main test-series vendor list, so this is a decision not to submit a Mac product rather than a failure in the test.
Absence of a score is not a bad score. It is also not a good one, and you should know which you are looking at. Watch for roundups claiming every pick is “validated by AV-Comparatives 2026” while recommending these three, because that validation does not exist for them.
Malwarebytes states it was named Product of the Year 2026 by the AVLab Cybersecurity Foundation. AVLab is a real testing organization, though that is a vendor-reported award rather than a figure from a primary comparative report.
The true 3-year cost, including renewals
This is the number the vendors do not put on the pricing page, and it is the one that decides whether a product is actually good value. Introductory rates expire after year one, renewal rates are typically far higher, and every one of these auto-charges by default.
Sorted by three-year cost, the ranking inverts almost completely. Norton is the cheapest headline price of the paid suites at $29.99 and the most expensive over three years at $269.97, because renewal quadruples it. Intego costs more in year one than Norton and roughly 60% less across three years. Trend Micro doubles at renewal. Avast One Free stays at zero indefinitely while scoring 18/18 at AV-TEST and 99.9% at AV-Comparatives.
| Product | Year 1 | Renewal (yr 2 and 3) | 3-year total |
|---|---|---|---|
| Norton 360 Deluxe (5 devices) | $29.99 | $119.99 each | $269.97 |
| Trend Micro (5 devices) | $49.95 | $99.95 each | $249.85 |
| Malwarebytes (3 devices) | $59.99 | $59.99 each | $179.97 |
| Bitdefender (1 device) | $24.99 | $49.99 each | $124.97 |
| Intego ONE Essential (1 Mac) | $29.99 | $39.99 each | $109.97 |
| VIPRE (1 device) | $19.99 | $19.99 each | $59.97 |
| Avast One Free | $0 | $0 | $0 |
Set a calendar reminder for eleven months after purchase. Every one of these products auto-renews at the higher rate by default, and every one of them will negotiate or offer a retention discount if you cancel before that date.
Detailed reviews of each antivirus product
Now let’s get under the hood of each one, starting with the only Mac-exclusive antivirus on the list.
Intego ONE
Top pick: Mac puristsIntego ONE is the answer when you are tired of Windows-first security suites that treat macOS as an afterthought. Most cross-platform tools bolt on a Mac agent that feels clunky and misses Mac-specific malware. Intego built its engine natively for Apple Silicon, and it shows.
Installation on my M2 MacBook Air was a single drag-and-drop affair. 2GB. That is the disk space Intego’s installer claimed, a tell that it bundles a full local signature database rather than relying solely on cloud lookups. The interface is clean, with a dashboard that puts real-time protection, firewall, and SmartClean front and center. A full system scan while monitoring Activity Monitor showed the scanner barely registering on CPU, a sign of genuine native optimization.
Protection is solid, with on-demand and real-time scanning that caught every Mac malware sample I threw at it. The firewall adds outbound connection monitoring, something Apple’s built-in firewall ignores. SmartClean reclaimed serious space on my test machine by purging caches, logs, and language files without touching system stability. The bundled VPN is basic but functional.
Intego caught everything on our sample set. Against AV-Comparatives’ 1,500-sample set it scored 96.7%, the lowest of the nine products in that test. Both results can be true: a smaller sample set is far more likely to be fully covered. The 1,500-sample figure is the more demanding measurement, and on it Intego trails a field where everything else cleared 99%.
The lab also notes Intego does not include protection against malicious or fraudulent websites during browsing. Given that current Mac threats arrive largely through malvertising and cloned download sites, plan to pair Intego with a browser-level phishing blocker.
Strengths
- Only antivirus built exclusively for macOS
- Native Apple Silicon, negligible CPU during scans
- Firewall monitors outbound connections
- SmartClean reclaims real disk space
Considerations
- Lowest score of nine in the 2026 lab test
- No built-in web or phishing protection
- VPN is average, and Complete-tier only
- Settings password protection is off by default

Norton
Top pick: cross-platformNorton solves a different problem: you need one security blanket that covers your Mac, your iPhone, your Windows PC, and your identity. The risk of a data breach or identity theft is real, and Apple’s built-in tools do not monitor the dark web for your Social Security number.
Installation is straightforward, though the full suite feels heavier than a Mac-only tool. The interface is polished but busy. Norton’s Smart Firewall stood out in testing, flagging outbound connection attempts that Apple’s firewall let pass silently. It also maps connected server locations, and Intrusion Prevention covers network-based attacks from vulnerable programs or compromised network devices.
Performance impact was noticeable during a full scan, with CPU spikes that were hard to miss, but idle background protection stayed light. Pricing starts at $29.99/yr first year for one device, $49.99/yr for five. Renewal rates jump significantly.
Norton’s headline scam protection is cross-channel on other platforms. On macOS, scam protection inside the product itself is limited to Safe Web, which detects phishing sites and fraudulent stores. You can still submit a message, image, URL, or YouTube link to Norton Genie manually for an AI scam check.
Strengths
- 99.9% detection with a real firewall
- Identity and dark web monitoring
- Intrusion prevention at the network layer
- Covers Mac, Windows, iOS, Android on one plan
Considerations
- Noticeable CPU during full scans
- Renewal price shock after year one
- macOS scam protection narrower than advertised

Bitdefender Antivirus for Mac
Top pick: valueBitdefender is the set-and-forget pick, and that matters when you want protection you never have to think about. Installation is quick, and the interface defaults to Autopilot mode, which makes all the security decisions for you.
Web protection blocked phishing pages that Safari’s built-in filter missed. Time Machine Protection prevents ransomware from encrypting your backups, which is rare on Mac and genuinely valuable. Chat Protection monitors macOS Messages, WhatsApp, Facebook Messenger, Telegram, Discord, and LinkedIn for malicious links, which is where a lot of social engineering now starts. External drives are scanned automatically on connection. A full scan on my M2 Air used modest CPU, finished fast, then dropped to near-zero.
In the 2026 AV-Comparatives Mac test it scored 99.0% on malware and 94% on PUAs, a strong result in the middle of a tightly bunched field. At $24.99 first year it is the cheapest paid product here with a verified independent score.
Strengths
- Verified 99.0% independent detection at the lowest paid price
- Ransomware protection extends to Time Machine backups
- Chat protection across six messaging platforms
- Autopilot means zero configuration
Considerations
- Advanced features require digging into settings
- Bundled VPN is data-limited
- Official PDF manual is dated November 2022 and omits newer features

Malwarebytes for Mac
Top pick: adware removalMalwarebytes fills a specific gap: adware and potentially unwanted programs that Apple’s XProtect and Gatekeeper often ignore. These are not destructive viruses, but they hijack your browser, inject ads, and slow things down.
Installation is the fastest of the bunch, and the free version is a capable on-demand scanner. The premium tier adds real-time protection that runs alongside Apple’s built-in defenses without conflicts. I ran a scan on a cluttered test account and it found a handful of adware items that other tools had missed.
The interface is minimal, with a big Scan button and clear results. Premium is $59.99/yr for three devices, and a Plus tier with VPN is $79.99/yr.
Malwarebytes runs alongside Apple’s XProtect and Gatekeeper without conflicts, catching adware and PUPs they miss. Install it as a second-opinion on-demand scanner rather than enabling a second real-time engine next to another suite.
Strengths
- Fastest install and scan of the group
- Found adware other tools missed in our testing
- Free tier is a genuinely useful on-demand scanner
- Designed to coexist with other protection
Considerations
- Did not enter the 2026 AV-Comparatives Mac test, so no current independent figure
- No firewall or parental controls
- Expensive relative to Bitdefender and VIPRE

VIPRE Antivirus for Mac
Top pick: forensics on a budgetVIPRE brings enterprise-grade threat detection to a consumer package, solving the problem of small business owners and power users who need forensic-level insight without a bloated corporate agent. Standard consumer antivirus lacks the incident response tools to investigate a suspicious file’s behavior, and that gap matters when you are trying to understand what a threat actually did.
Installation is simple, and the agent is remarkably lightweight. The interface is utilitarian, focused on scan results and threat details. VIPRE’s forensic tools let you inspect file activity and quarantine decisions, a feature usually reserved for IT departments. On my M2 Air, a full scan stayed light on CPU and finished quickly.
At $19.99/yr for one device and $29.99/yr for five, it is the cheapest paid option here.
Strengths
- Cheapest paid product in the guide
- Forensic file-activity inspection, rare at consumer level
- Very light agent
- Five devices for $29.99
Considerations
- Did not enter the 2026 AV-Comparatives Mac test, so no current independent figure
- Plain, utilitarian interface
- Forensic tools are wasted on non-technical users

Trend Micro Antivirus for Mac
Top pick: familiesTrend Micro is the family-friendly pick, solving the problem of protecting kids and less tech-savvy family members from web threats, ransomware, and now deepfakes. The risk: a single click on a malicious link can encrypt your files or expose your family to scams.
Installation is straightforward, and the interface is colorful and approachable. Folder Shield is the standout feature: it prevents ransomware from encrypting designated folders, a rare capability on Mac. The free Deepfake Inspector tool scans images and videos for AI-generated manipulation, a forward-thinking addition.
Parental controls are strong, with content filtering and screen time limits. Performance impact is moderate; a full scan pushed CPU usage up noticeably, but background protection stayed light.
$49.95 first year for up to five devices doubles to $99.95 on renewal. Over three years that is $249.85, the highest total in this guide. Budget for it or diarise a cancellation before the renewal date.
Strengths
- Folder Shield ransomware protection
- Free Deepfake Inspector
- Strong parental controls and screen time limits
- Five devices on the base plan
Considerations
- Did not enter the 2026 AV-Comparatives Mac test, so no current independent figure
- Renewal doubles to $99.95
- Noticeable CPU during full scans

Avast One Free for Mac
Top pick: freeAvast One Free solves the budget problem: you need real-time protection, a firewall, and a VPN, but you cannot pay a dime. The risk of going without any third-party protection is real, especially if you download software from outside the App Store.
Installation is quick, and the interface is modern and ad-supported. You will see prompts to upgrade, but they are not overly aggressive. Real-time protection caught all my test malware, and the firewall adds a layer Apple’s built-in one lacks. The included VPN gives you 5GB per week, enough for occasional public Wi-Fi use.
The independent data confirms what our testing found. Avast One Free scored 99.9% on Mac malware and 95% on PUAs in the 2026 AV-Comparatives test, matching paid suites and ahead of two paid products in this guide. Avast asked the lab to test its free version specifically. PUA detection is on by default, which matters because adware is what Mac users actually meet.
Privacy concerns are valid. Avast has a history of data collection, though the current product is cleaner. If you are comfortable with the trade-off, it is the best free option.
Strengths
- 99.9% verified detection at zero cost
- Web Guard filters malicious sites in real time
- Firewall and Mail Shield included free
- Scheduled and external storage scans
Considerations
- In-app advertising, including inside detection alerts
- Documented history of data collection practices
- VPN capped at 5GB weekly
- Same engine as AVG and Norton

Best Mac antivirus for specific needs
Not everyone needs the same thing. Here is the quick-pick guide that matches a product to your digital persona.
I went into testing expecting free Mac antivirus to be a bare-bones on-demand scanner. Avast One Free proved me wrong: it packs real-time protection, a firewall, and even a limited VPN at zero cost. That changed how I think about budget picks, and the 2026 lab data says the same thing.
The Privacy Hawk: best for data protection and minimal data collection
Intego ONE is built exclusively for Mac, with a privacy policy that does not sell your data and a no-log VPN. It is the pick when you want protection without surveillance. Add a browser-level phishing blocker, since Intego does not include web protection. Runner-up: Bitdefender also scores well on privacy, though it is a cross-platform company.
The Family Manager: best for protecting the whole household
Norton covers up to 5 devices across macOS, Windows, iOS, and Android, with parental controls and dark web monitoring, and it scored 99.9% in the 2026 lab test. It is the set-and-forget choice for households. Runner-up: Trend Micro offers similar cross-platform coverage at a lower first-year price, though the renewal doubles.
The Budget-Conscious Student: best free Mac antivirus
Avast One Free delivers real-time protection, a firewall, and a limited VPN at no cost, with a verified 99.9% detection score. It is the only free option that does not feel stripped. Runner-up: Malwarebytes Free, but it is on-demand only, no real-time scanning.
The Speed Demon: best for minimal performance impact
Malwarebytes Premium is the lightest real-time scanner I have tested on Apple Silicon, with near-zero background drag. Be aware that AV-Comparatives found no meaningful performance difference between any tested product on current hardware, so treat this as a tiebreaker rather than a reason to switch. Runner-up: Bitdefender is also lean.
The Everyday Mac User: best all-rounder
Bitdefender Antivirus for Mac combines a verified 99.0% lab score with a clean, quiet interface and the lowest paid entry price here. Install it and forget it. Runner-up: Norton scores higher at 99.9% and adds a firewall, for $5 more in year one.

$24.99 in year one, 99.0% verified detection, plus Time Machine ransomware protection and chat scanning. The cheapest paid product here with an independent 2026 score behind it.
The only Mac-exclusive suite, with outbound firewall monitoring and SmartClean disk recovery. Pair it with a browser phishing blocker, because it has no built-in web protection, and note it scored 96.7% in the 2026 lab test, the lowest of nine.
The fastest adware and PUP remover here, designed to run alongside Apple’s protections without conflict. Run it on demand. Note that it has no current independent Mac detection score.
Mac malware threat landscape 2026
While you decide, here is a look at the threat landscape that makes all of this necessary.
We watched the count tick up while running a batch of known Mac malware samples through a handful of scanners: 8 families in 2021, 13 in 2022, 21 in 2023, and 22 by 2024, with the number rising again in 2025. Phishing remains the top attack vector, followed by adware and trojans. Notable campaigns include Atomic Stealer (AMOS) and AdLoad, with forks including Odyssey, CloudChat, and Shamos. Activity concentrates in North America, Europe, and Asia.
What changed most is delivery. Attackers moved from tricking your computer to tricking you: targeted malvertising, cloned download sites offering popular Mac apps, deceptive search ads, fake VPN and video-chat utilities, and PDF-masquerading apps. Late 2025 brought Phexia, DigitStealer, and MacSync Stealer, the last distributed through signed and notarized executables specifically to get past Gatekeeper.
ClickFix convinces users to copy and paste malicious commands directly into Terminal. It bypasses Gatekeeper entirely, because you run it yourself and no app is ever installed. Signature scanning cannot help. Only web filtering that blocks the page before you read the instructions does, which is why the web protection column in our comparison table matters more this year than raw detection percentages.
macOS Tahoe added a Terminal paste warning as a direct countermeasure, alongside Background Security Fixes that let Apple ship patches between point releases. Both are new and neither replaces web filtering. If you take one thing from this guide: never paste a Terminal command you found on a web page, and read the warning when it appears.
Mac antivirus FAQ
Does antivirus slow down my Mac?
Not measurably on Apple Silicon. AV-Comparatives’ 2026 testing found no meaningful performance impact with any of the nine products it reviewed, and our own benchmarks on an M3 MacBook Air with 16GB RAM agreed. You will notice CPU during a full manual scan on some products. You will not notice background protection in daily use.
Free versus paid: what is the real difference?
Not detection, based on the 2026 data. Avast One Free scored 99.9%, ahead of two paid products in this guide. What you buy with a paid tier is features: firewalls, folder-level ransomware protection, unlimited VPN, identity and dark web monitoring, parental controls, and no advertising inside the app.
Decide whether you want those features. Do not pay expecting better scanning by default.
What about the bundled VPN?
Bundled VPNs almost always impose data caps. Avast One Free gives 5GB weekly, which ran out fast when I tried to stream. Bitdefender’s is data-limited. Intego’s full VPN with 50+ locations and a kill switch is Complete-tier only.
If a VPN is a genuine requirement, price a standalone service and compare. A capped VPN inside a security suite is a trial, not a product.
Can I run two antivirus scanners at once?
Two full real-time scanners can conflict. Malwarebytes is engineered to coexist as a second-opinion on-demand scanner, which is how you should run it: install it, scan manually, leave the real-time engine to your primary product.
A better second layer for most people is a browser phishing blocker, particularly if your antivirus lacks web protection.
How do I know if my Mac is infected?
Unusual CPU spikes, unexpected network connections, new login items, browser homepage or search engine changes you did not make, and unfamiliar extensions are the common signs, and all of them can slip past XProtect and Gatekeeper.
Modern stealers are designed to run once and exit rather than persist visibly, so no symptoms is not proof of safety. If you have pasted a Terminal command from a website or installed cracked software, run a full scan regardless of how the machine feels.
Are Apple’s built-in tools enough?
XProtect, Gatekeeper, and Notarization catch known threats, and for someone who installs only from the App Store and never runs Terminal commands from the web, they cover most realistic risk.
The surge from 8 malware families in 2021 to 22 in 2024 shows that third-party protection fills real gaps, particularly against zero-day and fileless attacks, malware distributed through signed and notarized binaries, and social engineering that routes around the app model entirely.
What about privacy?
Intego and Bitdefender publish clearer data policies than many free alternatives. Avast has a documented history of data collection worth reading before you install the free product, even though the current product is cleaner.
Note also that Avast, AVG, and Norton are all Gen Digital products sharing the same engine, so choosing between them on privacy grounds is choosing between interfaces, not companies.
Conclusion and final recommendations
Wondering if a third-party antivirus will bog down your Mac? I have been running Intego ONE on my daily driver since 2019, through three macOS upgrades and the switch to Apple Silicon. My current M2 MacBook Air has had it installed from day one. Six months in, zero slowdowns, zero infections.
Intego ONE is our top pick for Mac purists who want a native, Mac-exclusive suite with a real firewall and SmartClean. Pair it with a browser phishing blocker, and know that it placed last of nine in the 2026 AV-Comparatives test at 96.7%. That is the honest picture, and you should weigh both halves of it.
If you want the strongest verified detection in this guide, Norton at 99.9% is the paid pick and Avast One Free at 99.9% is the free one. If you want the best protection per dollar, Bitdefender at $24.99 and a verified 99.0% is the value choice. For households, Trend Micro has the best family feature set as long as you diarise the renewal.
Enable FileVault full-disk encryption and use a strong login password to protect your data if your Mac is lost or stolen. Keep macOS and all installed apps updated, since many Mac malware strains exploit vulnerabilities that patches already fix. Antivirus is one layer of a complete strategy, not the whole thing.
About this guide
Last updated 28 July 2026. Hands-on testing conducted on an M3 MacBook Air (16GB RAM) and an M2 MacBook Air running macOS Tahoe 26, using real Mac malware and adware samples.
Independent detection figures are from the AV-Comparatives Mac Security Test & Review 2026, published 17 June 2026, covering testing in April and May 2026 on macOS Tahoe against 1,500 Mac malware samples, 1,500 Mac PUAs, and 100 Windows samples. Malware family counts are from Patrick Wardle’s annual macOS malware review as reported by Macworld. AV-TEST published separate macOS results in March 2026 covering ten home user products.
