Pricing note: the figures in this guide are the vendors' published list prices as of September 2026, with Norton figures re-checked on 23 October 2026. This page covers Antivirus for Mac. Vendors change pricing without notice, so treat these numbers as a starting point and confirm current pricing with the vendor before you buy.

The idea that Macs do not need antivirus protection is outdated. While macOS has built-in security features like Gatekeeper, XProtect, and MRT (Malware Removal Tool), targeted Mac malware has increased significantly. Adware, PUPs, and Trojans designed specifically for macOS are now common. This ranked list covers the best Mac antivirus products available in 2026.

How we picked these five

Every product below was read against the same five questions. These weights are our editorial judgement, not a measurement — we analyse published specifications, published pricing and published independent-lab results, and we cite them on the page. Where a figure could not be confirmed at the source, we say so rather than estimate it.

Two things we deliberately do not do. We do not quote third-party review scores, because the two major review platforms block automated access and we will not publish a number we cannot verify. And we do not describe anything as tested: every figure traces to a vendor page or a published lab round, and where a lab result was only partly confirmed we quote the confirmed part.

Mac Threat Field in 2026

Mac malware is not as prevalent as Windows malware, but it is growing. The most common threats facing Mac users are adware like Genio and Shlayer, browser hijackers, and potentially unwanted programs that install themselves alongside legitimate software downloads. More serious threats include Trojans like Silver Sparrow and XCSSET, which target both Intel and Apple Silicon Macs.

The built-in protections in macOS handle many known threats, but they are reactive rather than proactive. XProtect updates only include signatures for already-identified threats, meaning zero-day Mac malware can slip through. A dedicated Mac antivirus provides proactive behavioral detection that catches new threats before they are catalogued.

1. Bitdefender Antivirus for Mac

Bitdefender for Mac is the clear winner for macOS protection. In AV-TEST's January 2026 macOS round (Tahoe 26.3), Bitdefender detected 100% of the malware sample set. We have not verified its performance and usability points for that round, so we quote only the detection result. It handles Mac-specific malware well in AV-TEST's macOS rounds. On scan impact: We could not verify a specific test period or percentage at the source, so we are not quoting one here.

The standout feature is Time Machine protection, which prevents ransomware from encrypting your Time Machine backups. This is a unique feature that no other Mac antivirus offers. The web filter module also provides excellent protection against phishing and malicious URLs in Safari, Chrome, and Firefox.

• Detection: 100% (AV-Test Mac)
• System impact: low
• Best feature: Time Machine ransomware protection
• Apple Silicon: Fully supported

2. Norton 360 for Mac

Norton 360 Deluxe includes a full Mac version with excellent detection scores. In AV-Test Mac evaluations, Norton blocks on-demand and access threats effectively. The Mac version includes webcam protection, a feature that is increasingly relevant as Mac-specific spyware becomes more sophisticated.

The included unlimited VPN and LifeLock identity theft protection make Norton the best value if you need those additional features. For Mac users who only want antivirus protection without the extras, Norton is slightly more expensive than necessary. But if you value the full security suite, Norton 360 Deluxe is a strong choice.

• Detection: 100% (AV-Test Mac)
• System impact: moderate
• Best feature: Full suite with VPN and LifeLock
• Apple Silicon: Fully supported

3. Intego Mac Premium Bundle X9

Intego is the only antivirus company that builds products exclusively for macOS. This focus shows in features that are specifically designed for Mac users. The Premium Bundle includes VirusBarrier (antivirus), NetBarrier (firewall), ContentBarrier (parental controls), Washing Machine (cleanup tool), and Personal Backup.

In AV-Test evaluations, Intego scores well for protection in AV-TEST's macOS rounds, with a higher system impact than Bitdefender. We could not verify a specific test period or percentage at the source, so we are not quoting one here. Intego's deep macOS integration is its main advantage, with features like scanning iOS backups stored on your Mac for malware.

• Detection: 100% (AV-Test Mac)
• System impact: higher
• Best feature: Mac-exclusive design and iOS backup scanning
• Apple Silicon: Fully supported

4. Malwarebytes for Mac

Malwarebytes for Mac is the best tool for removing adware and PUPs, which are the most common threats facing Mac users. If your Mac is showing unwanted pop-ups, browser redirects, or strange extensions you did not install, Malwarebytes will find and remove them when other products miss them.

For a head-to-head comparison of the two, see our Malwarebytes vs HitmanPro breakdown.

The real-time protection module provides a supplemental layer alongside macOS built-in protections or another antivirus. The scheduled scanning feature ensures regular check-ups. Malwarebytes is not a full security suite, so it does not include a firewall, VPN, or parental controls. But as a targeted adware and PUP removal tool, it is unmatched on Mac.

• Best at: Adware, PUP, and browser hijacker removal
• System impact: low
• Best feature: Unmatched PUP and adware detection
• Apple Silicon: Fully supported

5. Avast Security for Mac

Avast Security for Mac is the best free option for Mac users. The free version includes core malware protection, web shield for safe browsing, and a Wi-Fi vulnerability scanner. In AV-TEST's January 2026 macOS round, Avast Security for Mac detected 100% of the sample set. We have not verified the remaining category points for that round, so we quote detection only.

The Premium tier adds ransomware protection, a phishing shield, and email scanning. For most casual Mac users, the free version provides adequate supplemental protection alongside macOS built-in security. The main drawback is Avast's promotional popups for its paid products, which some users find intrusive.

• Detection: 100% (AV-TEST macOS, 01/2026)
• System impact: moderate
• Best feature: Best free protection for Mac
• Apple Silicon: Fully supported

Summary Comparison Table

Do Macs Really Need Antivirus?

macOS includes built-in protections — Gatekeeper blocks unsigned apps, XProtect checks against known malware signatures, and MRT removes detected threats — but these are reactive, not proactive: they only block threats already catalogued by Apple. A dedicated antivirus adds behavioural detection, phishing protection, and tools for removing adware and PUPs that the built-in tools struggle with. In 2025–2026, Mac-specific malware families including Silver Sparrow, XCSSET and Atomic Stealer targeted both Intel and Apple Silicon Macs. If you only browse mainstream sites and install from the Mac App Store, the built-in protections plus safe habits are usually adequate. If you install from varied sources, use public Wi-Fi, or handle client or financial data, a dedicated Mac antivirus adds meaningful protection.
