Even Macs Need Antivirus Protection

You heard it on the TV—Macs don't get viruses. And like much of what you hear on the TV, this isn't true. Sure, macOS is intrinsically more secure than Windows or Android, but Mac-centered malware totally exists. The time to think about protecting your Mac is now, not after you've lost all your important documents to ransomware. If you're picking a Mac antivirus for the first time, don't worry. Our reviews will help you make an informed choice.

As with Windows antivirus tools, the most common price is just under $40 per year for a single license. ProtectWorks is unusual in that a single $29.95 payment lets you protect all the Macs in your household, with no subscription needed. McAfee goes beyond that, with a $59.99 per year subscription that protects all your Macs, PCs, Android, and iOS devices. With Sophos Home Premium, $60 per year lets you install and remotely manage protection on 10 Macs or PCs. At the high end, you pay $99.99 per year for a three-license subscription to Intego Mac Internet Security X9.

You may have heard that macOS Mojave, the latest macOS, advances the platform's privacy and security. Safari on Mojave automatically blocks ads and social media trackers. The built-in password manager does more than ever. And when AppleScript apps try to access internal macOS features, Mojave makes them wait until you give permission. But nothing we've seen suggests that upgrading to Mojave will obviate the need for an antivirus utility.

Free Mac Antivirus Protection

There's another angle to the variation in Mac antivirus pricing. How about paying nothing at all? Avast Security (for Mac), AVG AntiVirus for Mac, Avira Free Antivirus for Mac, and Sophos Home Free (for Mac) are totally free for personal use, although Sophos technically limits you to three devices, macOS or Windows. AVG also offers free antivirus for Mac, but until its phishing protection improves we can't recommend it. The best commercial products offer more protection but if you can't afford the best, at least install a free antivirus.

What's Not Here

Every macOS antivirus that earned 3.5 stars or better appears in the chart above. Another half-dozen managed a decent three-star rating, but there isn't room for another six products. I chose to favor three products that originated on the Mac platform, ClamXAV and Intego Mac Internet Security. Everything else being equal, there's surely some virtue in loyalty to macOS.

Avast Security Pro (for Mac), ESET Cyber Security (for Mac), and Malwarebytes for Mac Premium also earned three stars, as did the Mac-specific ProtectWorks AntiVirus. However, ProtectWorks, ESET, and Malwarebytes don't have any lab results at present, and with Avast, you might as well use the free edition, because you don't get a lot more by paying. These four didn't quite make it into the chart. The names Avast, ESET, and Malwarebytes are well known in Windows circles. If you're using a Windows security product from one of these companies, it makes sense to do the same on your Macs.

Malware Protection Lab Certifications

When you go to select a new washer, refrigerator, or other appliance, chances are good you research it first. User reviews can be helpful, as long as you discard the very best and very worst of them. But actual test results performed by an independent lab give you more reliable information. Two large labs include macOS antivirus products in their testing, but the slate of products for testing is variable. When we first rounded up Mac antivirus products, all those in the chart below had at least one certification, but at present, many of them don't appear in either lab's test results.

The researchers at AV-Test Institute evaluate Mac antivirus products on three criteria: protection, performance, and usability. A product can earn up to six points for each. Protection against malware protection is essential, of course, as is a low impact on performance. A high usability score reflects a small number of false positives, legitimate programs and websites identified as dangerous. Several products achieved a perfect 18 points, all six points for all three criteria.

In the macOS malware test by AV-Comparatives, most charted products scored 100 percent. This lab, too, included a test using malware aimed at Windows. Yes, these samples can't affect a computer running macOS, but they could conceivably escape to Windows machines on the network. Scores in the Windows malware test ranged from zero to 100 percent, which is quite a span.

Results in macOS-specific tests have a much smaller point spread than in tests of Windows antivirus utilities. It's good that many products in the chart received at least one certification for Mac protection, and even better that some received two certifications.

Hands-On Phishing Protection Testing

When we test malware protection on Windows, we use live malware inside an isolated virtual machine. We've coded a number of analysis tools over the years to help with this testing. Little of that testing regimen carries over to the Mac.

Phishing, however, isn't platform-specific, and neither is our antiphishing test. Phishing websites imitate secure sites, everything from banks and finance sites to gaming and dating sites. If you enter your credentials at the fake login page, you've given the phisher access to your account. And it doesn't matter if you are browsing on a PC, a Mac, or an internet-aware sewing machine.

Almost all the products in the chart below include protection against malicious and fraudulent sites. With ClamXAV and Intego, this just isn't an included feature. Malwarebytes and ProtectWorks also lack an antiphishing component.

The wily malefactors who create phishing sites are in the business of deception, and they constantly change and update their techniques, hoping to evade detection. If one fraudulent site gets blacklisted or shut down by the authorities, they simply pop up with a new one. That being the case, we try to use the very newest phishing URLs for testing, scraping them from phishing-focused websites.

We launch each URL simultaneously in four browsers. One is Safari or Chrome on the Mac, protected by the Mac antivirus that's under test. The other three use the protection built into Chrome, Firefox, and Microsoft Edge. Discarding any that don't fit the phishing profile, and any that don't load correctly in all four browsers, we report the product's detection rate as well as the difference between its detection rate and that of the other three test systems.

Most of the products in this roundup beat the combined average of the three browsers. Kaspersky and McAfee top the list with 100 percent detection, while Bitdefender's score of 99 percent comes close behind. All three of these winners scored precisely the same when tested under Windows.

Ransomware Protection

The scourge of ransomware is on the rise. While ransomware attacks are more common on Windows devices, Macs have suffered as well. Of course, any antivirus utility should handle ransomware just as it handles spyware, Trojans, viruses, and other malware types. But since the consequences of missing a ransomware attack are so great, some security products add components with the sole purpose of preventing ransomware attacks.

We've observed a wide variety of ransomware protection techniques on Windows. These include blocking unauthorized access to user documents, detecting ransomware based on its activity, and recovering encrypted files from backup. Of the products listed here, Bitdefender and Trend Micro offer a ransomware component that blocks unauthorized modification of protected documents.

As with Bitdefender's Windows edition, the Safe Files feature prevents all unauthorized access to your documents. On a Mac, it also protects your Time Machine backups. Trend Micro offers multiple layers of Windows ransomware protection. Folder Shield, which, like Safe Files, prevents unauthorized document access, is the only layer that made its way to the macOS edition.

Sophos Home Premium includes the same CryptoGuard behavior-based ransomware protection found in its Windows equivalent. Our Windows test sytsems are virtual machines, so we feel free to release real-world ransomware for testing. We just roll back the virtual machine to a clean snapshot after testing. We don't have the option to do that on the physical Mac testbed, so we just have to figure that since it worked on Windows, it probably works on macOS.

Spyware Protection

Any kind of malware problem is unpleasant, but spyware may be the most unnerving. Imagine some creeper secretly peeking at you through your Mac's webcam! Other types of spying include logging keystrokes to capture your passwords, sending Trojans to steal your personal data, and watching your online activities to build a profile. As with ransomware protection, we've observed more features specifically devoted to spyware protection on Windows-based security products than on the Mac, but a few products in this collection do pay special attention to spyware.

Under Windows, Kaspersky's Safe Money feature opens sensitive sites in a secure browser that's hardened against outside interference. The Safe Money feature on the Mac doesn't do that, but it does check URLs to make sure you're on a legitimate secure site. Kaspersky offers an onscreen keyboard, so you can enter passwords with no chance of capture by a keylogger. Its webcam protection isn't as configurable as it is on Windows, but you can use it to disable your Mac's webcam whenever you're not using it. It even includes the ability to block advertisers and others from tracking your online activities. If spyware is your bugaboo, you'll like Kaspersky.

Sophos Home Premium offers protection for the webcam and microphone that's more substantial than Kaspersky's. You get a notification any time an untrusted program attempts to access either; you can allow access or stop the program. There's also an option to whitelist a program, so you don't get a popup every time you use your off-brand video chat tool.

Bonus Features

Many antivirus tools on Windows pack in a ton of bonus features, packing in everything from tune-up utilities to VPNs. That behavior seems less common on the macOS side, though Norton now includes a VPN with no bandwidth limits. Even so, some vendors don't have a standalone Mac antivirus, opting instead to offer a full security suite as the baseline level of protection, and a few others include suite-like bonus features in the basic antivirus.

A typical personal firewall component blocks attacks coming in from the internet and also manages network permissions for programs installed on your Mac. Intego, McAfee, and Norton each include a firewall component, while Kaspersky's Network Protection comes close.

Parental control is another common suite component. With Sophos (free or premium) and Trend Micro Antivirus for Mac, a content filter can block access to websites matching unwanted categories. Kaspersky goes beyond that, with content filtering, screen time limits, and control over apps used. An additional $14.99 per year unlocks all the features of the powerful Kaspersky Safe Kids.

Protect Your Mac

Most of the products covered in this roundup earned certification from at least one independent testing lab; some managed two certifications. There really are no bad choices here, as far as basic antivirus protection goes. Even so, a few products stood out. Bitdefender Antivirus for Mac not only achieved certification from both labs, it earned the maximum score in every test, and took the top antiphishing score. Kaspersky Internet Security for Mac also earned high scores. It offers a full suite of Mac security tools, at the same price competitors charge for basic antivirus protection. Symantec Norton 360 Deluxe (for Mac) is also a suite, and its features include a no-limits VPN. These three are our Editors' Choice winners for Mac antivirus protection.

Look over the reviews, pick the product that suits you best, and get your Mac protected. Once you've done that, you should also consider installing a Mac VPN. While an antivirus protects you, your devices, and your data locally, a VPN extends that protection to your online activities, protecting both your security and your privacy.

Editors' Note: We are aware of the allegations of Kaspersky's inappropriate ties to the Russian government. Until we see some actual proof of these allegations, we will treat them as unproven, and continue to recommend Kaspersky's security products as long as their performance continues to merit our endorsement.

    Read Review

Many casual users may think that identifying the best Mac antivirus software in 2019 is rather redundant, given that Macs 'don't get viruses.'

Yet although Apple machines are targeted less than their Windows counterparts, they can still be infected - and the risks are increasing, which is why you need protection.

Every product in this list has been chosen because it's especially designed to protect Mac systems and has scored highly at identifying and removing viruses and malware.

  • We've also highlighted the overall best antivirus

The macOS operating system is based on Unix, which is sandboxed, meaning it can be very difficult for viruses to do any damage. Think of them as locked in a little box from which they can’t escape, no matter how hard they try.

This means that you will need specific Mac antivirus software - whether that be the very strongest paid-for protection or a free download that we've picked out at the bottom of this guide - that's been designed to work with the unique demands that macOS has.

So read on for our top choices..

Mac antivirus: which is best at detecting threats?

The excellent AV-TEST regularly puts anti-virus programs through their paces, and their most recent tests took place in June 2018 on macOS High Sierra. They tested two key areas: how well the packages detected Mac-specific threats, and how well they protected against Macs in mixed-OS environments being hijacked to spread Windows malware.

While the amount of Mac malware is still considerably less than that targeting Windows, its still 100 times higher than what experts predicted just a few years ago.

For Mac malware, six packages achieved 100 percent detection without false positives:

1. Bitdefender Antivirus for Mac

Bitdefender Antivirus for Mac
$38.99
Integrates well with Mac OS
Not as many features as some competitors

Bitdefender Antivirus for Mac is one of the most accurate virus protection suites for Apple devices on the market, and it comes with a host of features, including multi-layer ransomware protection, adware removal, and it can also scan for Windows PC malware as well.

If you're concerned about internet nasties, Bitdefender Antivirus for Mac is the best software for Macs in 2019.

2. Intego Mac Internet Security X9

Mac internet security
Accurate virus scanning
Somewhat limited features

Intego has been protecting Macs for 20 years, so if there's any software that knows what kind of security Apple machines need, this is it.

It comes with an antivirus engine that cans for the latest Mac threats, as well as Windows and Unix malware as well, and it also features a full firewall for managing network permissions.

3. Kaspersky Internet Security for Mac

Kaspersky Internet Security for Mac
Good detection rates
User interface won't be to everyone's taste

Kaspersky is a well regarded name in the field of antivirus protection, and it maintains that reputation with its Internet Security for Mac software, which brings a range of features that put much of its competitors to shame, including protection against ransomware, parental controls and tools to make sure you can shop and bank completely securely online.

The huge range of features are certainly welcome, but it can make the interface a bit cumbersome to navigate if you're looking for a particular tool.

4. Norton Security Deluxe

Norton 360 Deluxe
$59.99
Excellent detection
Can impact speed of your Mac

Norton is another brand that's well known in the antivirus world, and the Norton Security Deluxe software helps protect your Mac with an excellent malware detection engine. It can cover a range of devices, so you can have it protect your Macs, or even any Windows PCs you have, or mobile devices. While the security it offers is great, there can be a noticeable impact on system speed when in use.

If you want to keep your Mac feeling as speedy as possible, look at one of the other choices in this best software for Mac list, but if you want robust, dependable protection, no matter what, then Norton Security Deluxe is definitely worth investing in.

The next four achieved between 99.5 percent and 98.4 percent without false positives:

5. Trend Micro Antivirus for Mac

Good security that includes social network protection

Trend Micro Antivirus for Mac
Good protection
Not the most accurate detection

If you're running the latest version of macOS, macOS High Sierra (10.13), then Trend Micro Antivirus for Mac is a very good choice, as it has been built for compatibility with the recent operating system. It brings antivirus protection, email scam filtering, a social media privacy checker and new ransomware protection tools.

Scanning speed has also been improved since the last version, making it faster to check your Mac for any viruses.

6. ClamXAV

A trusted scanner for macOS

ClamXAV for Home Users
Mac-specific tools
No website filtering

ClamXAV doesn't have the catchiest of names, but it's the antivirus software for Mac that many IT professionals swear by - not least because it only creates AV for Apple computers.

That doesn't mean it's overly complicated - in fact, it has one of the most simple and easy-to-use interfaces out of all the Mac antivirus software on this list.

It's particularly adept at catching viruses in email attachments, and while it doesn't come with some of the internet safety tools of other suites, it's still an excellent choice for protecting your Mac.

7. ESET Cyber Security for Mac

ESET Cyber Security for Mac
Plenty of features
No website filtering

ESET Cyber Security for Mac scores highly from independent testing labs, so you can rest assured that your Mac is being well looked after if you have this installed.

Antivirus

It's not the quickest software to scan your Mac for viruses, but it digs deep into your system to make sure your machine is completely free from viruses, and it has a pretty competitive price tag as well.

8. F-Secure SAFE

F-Secure 1 Year
$34.99
Strong protection
Integrated parental controls

F-Secure SAFE is pitched as an antivirus service for the entire family, protecting all manner of devices, including PCs, smartphones, tablets as well as Macs, and strong parental controls.

AV-Test found F-Secure protected against 100 per cent of zero-day threats during March and April 2018, as well as 100 per cent of all widespread and prevalent malware discovered during the previous four weeks. However as of June 2018, detection rates of MacOS malware are 96.4 per cent.

Concerns about the suite slowing down the installation of frequently used applications also persist, as does a relative lack of features. Having said that it does offer some nifty capabilities such as banking protection, which blocks specific sites and apps from interacting with your system while you’re logged in, and specific safeguards across the scourge of ransomware.

In short, F-Secure’s user-friendly UI and accurate protection make it an adequate choice, but it is lacking in the feature department.

Do I need free or paid-for antivirus for Mac?

The debate is the same regardless of whether you have a Mac or a PC. Free antivirus products are effective at protecting against threats but they lack certain premium features.

Having multiple systems on a network means cyberattacks have more users and more endpoints to target. Additional management tools that let you set policies can help mitigate this risk.

Macs might be considered safer than PCs, but it still might not be risking it for the sake of saving some money.

Top 5 best free antivirus for Mac in 2019

1. Avast Free Mac Security

Strong all-round protection for your Mac

Avast Free Mac Security
Real-time protection
Detects network vulnerabilities

Avast Free Mac Security goes the extra mile to protect your Mac with an unusually lengthy feature list.

The core antivirus engine offers real-time protection to catch threats when they appear, for instance. You can run on-demand full system scans if you suspect a problem, or launch a more targeted check on specific files, folders or drives. It's even possible to schedule scans to run automatically when you're not around.

A Web Shield warns you about malicious websites, blocks dangerous downloads and email attachments, and protects your privacy by eliminating intrusive ad tracking.

There's an unusual extra in Avast's wireless network scanner, which quickly checks your network, router and connected devices, alerting you to any vulnerabilities.

Mac antivirus software isn't often checked by the independent testing labs, but Avast's most recent results were good, with AV Comparative's 2018 test finding the package detected 100 percent of sample threats.

If you'd like even more, upgrading to Avast Security Pro gets you ransomware protection and instant alerts of Wi-Fi intruders or changes in your network security. A one Mac, one-year licence can be yours for £49.99 ($70).

2. Avira Free Antivirus for Mac

Block the latest malware before it can cause damage

Avira Free Antivirus for Mac
Real-time protection
No web filtering

While many antivirus companies try to win you over by piling on the features, Avira Antivirus for Mac takes a simpler, more lightweight approach. There's no web filtering, no network scanning or other security extras: it's purely focused on keeping your system malware-free.

That doesn't mean the package is short on power. Its real-time scanner checks any file the system accesses, picking up threats before they can do any harm. The scheduler enables setting up the app to scan your system automatically, or you're able to check your entire system whenever you like.

As a bonus, the app doesn't just protect against Mac threats. It also uses Avira's Windows experience to pick up any PC-related malware, ensuring you won't share any files that might endanger your friends.

The main testing labs haven't evaluated Avira Free Antivirus for a while, but AV Comparatives last report found the Avira engine blocked 100% of test malware (tying with Avast), and with Avira's strong record on the PC we've no doubt that this is an app you can trust.

Although this list is all about free Mac antivirus, Avira deserves a mention for its commercial Avira Antivirus Pro product. It includes tech support and protects up to three devices with one licence (Mac, Windows and Android) for a cost of £39.99 ($42) a year.

3. Bitdefender Virus Scanner for Mac

Bitdefender Virus Scanner for Mac
Easy to use
No real-time protection

Bitdefender Virus Scanner is a lightweight free malware hunter which can track down and remove both Mac and Windows-related threats.

A simple and straightforward interface makes the app extremely easy to use. A status display keeps you up-to-date on how your system is doing, and four buttons enable running a quick scan of critical locations, an in-depth check of your entire system, or speedy scans of running applications or a folder of your choice.

Best Antivirus 2018 For Android

Although this looks all very basic, use Bitdefender Virus Scanner for Mac for a while and you begin to notice some very neat touches.

The app doesn't force you to wait a day for your next virus signature updates, for instance. Bitdefender issues updates every hour and Virus Scanner always fetches the latest version before it starts a scan.

An option to exclude files and folders from the scan - network shares, system backups - is another plus, reducing the work the engine has to do and significantly speeding up your scan times.

What you don't get here is any form of real-time protection or web filtering, essential tools for a complete security solution. This simplicity also reduces the chance of conflicts with other apps, though, suggesting Bitdefender Virus Scanner could be a useful second opinion tool which you run alongside another security app.

Quick and easy anti-malware from a big-name provider

Malwarebytes Premium for Mac 1 Year
$39.99
Malwarebytes Premium for Mac 2 Years
$59.99
Lightweight
No real-time protection

Mac antivirus software isn't just about detecting the latest most deadly ransomware, or other high-risk threats. Most tools can also strip out adware and other potentially unwanted programs which may not be highly dangerous, but are wasting system resources and slowing your Mac down.

Malwarebytes has been eliminating the full range of Windows threats since 2006, and the Mac edition is just as simple, straightforward and effective.

The app is such a lightweight installation, the size of three digital music files, that you'll barely notice it's there. And while the lack of real-time protection means Malwarebytes can't stop attacks - only remove existing infections - it also ensures there's no real impact on your system resources and the app is unlikely to conflict with other antivirus tools.

Performance is another highlight, with Malwarebytes claiming the average system is scanned in less than 15 seconds. Set it running when you check your emails in the morning and it'll be finished before you are.

Installing Malwarebytes for Mac also gets you a 30-day trial of the Premium edition which is able to detect and block threats as they appear. If you're not interested in this, ignore it; real-time protection will disappear when the trial expires and you'll get on-demand scanning only.

Alternatively, upgrading to Malwarebytes Premium with a one-year licence costs just £29.99 ($38), with another option to protect up to 10 devices for £49.99 ($65)

5. Sophos Home for Mac

Sophos Home Premium
Sophos Home free
Loads of features
Protect Macs and PCs from one account

The free antivirus market is highly competitive and it can be difficult for individual companies to stand out from the crowd, but the British vendor Sophos has found a way: it gives you more features in its free products than many competitors provide in their paid editions.

On-demand scanning to clean up infected systems? Check. Real-time protection to prevent attacks in the first place? Of course. Browser filtering which blocks access to dangerous sites? Naturally. Parental controls to define the content your child can access online? Yep.

Oh, and you can cover up to three Mac or Windows devices with a single account, and remotely check and manage their status from a central web console - potentially very useful when protecting the whole family.

Sophos isn't just piling on these extras to disguise a weak antivirus engine, either. AV Test's December 2017 Mac detection rate tests showed Sophos delivered the same level of protection as products from Avast, Bitdefender, Kaspersky and other big names.

This works for us, but if you need more, Sophos Home Premium does have some worthwhile extra features: advanced ransomware protection, monitoring of access to your webcam and microphone, live chat and email support, and the option to protect up to 10 devices. It's a strong feature set, and competitively priced at £37.50 ($48) a year.

Mac antivirus: what’s the effect on performance?

Most of us believe that virus protection software has a negative effect on performance, but chances are it’s much less negative than we think: in their tests, AV-Test found that there was no measurable performance drop when using ClamXav, MacKeeper, Kaspersky or Norton. There was a measurable difference with Sophos and Trend Micro (two per cent of additional system load), and with ESET and Bitdefender, which added around four per cent to the overall system load.

Mac antivirus: do I really need it?

That really depends on you. The risk of infection remains pretty remote, and if you practice basic security measures and don’t fall for common scams then you’re very unlikely to suffer from any problems. Even ransomware can be defeated with the cunning tactic of having a backup of anything important.

That said, if you’ve ever experienced the mess malware can make on a Windows system you’ll know that just getting things back to normal can be an incredible time thief, especially if key data has been damaged. Perhaps the question shouldn’t be whether anti-virus is worth the money, but whether your time is more valuable than the cost of a security app.
