Which Virus Protection Is Best For Mac

Even Macs Need Antivirus Protection

Best free antivirus for Mac: Avast Free Mac Security Many antivirus suites provide a decent level of protection, but a few rise above all others by providing the very best in performance. Avast Security (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.

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.

Avast Free Mac Security

What We Like

Detects several types of malware.
Blocks your computer from sending and receiving viruses in emails.
Able to minimize its impact on system resources.
Includes other security tools.

What We Don't Like

Some features only work in the pro edition.
Might take a while to install.

Avast Free Mac Security uses a traditional signature-based method to scan files on your Mac for known malware, Trojans, and viruses. Avast can root out rootkits and other methods that a hacker uses to gain control and is able to pry open compressed files to scan their content.

Beside malware designed for the Mac, Avast also looks for PC malware to help keep cross-platform infections from occurring. You don’t want to be the person sending off infected email attachments to your PC friends.

Avast uses real-time detection that runs in the background. Avast, like other antivirus apps that continually run in the background, can have an impact on your Mac's performance. Avast, however, gives you the option of using its real-time detection, or a scheduling system that can have less impact on your Mac's performance.

Scheduled scans allow you to set the time for Avast for Mac to run its routine scans for the presence of malware. Moving the scheduled time to when it will least impact your workload is a big plus.
File shield can check all of the files on your Mac for nefarious content. Files can also be checked by file type or location on your Mac.
Web shield blocks unsafe websites from loading or downloads from those sites from occurring.
Mail shield prevents dangerous email attachments from downloading or from being executed.
Local network scan makes sure your home network and all connected devices are free from vulnerabilities that hackers could make use of to steal personal data.

Bitdefender Antivirus for Mac

What We Like

Easy to set up and forget about.
Finds malware automatically.
Includes lots of really great features.
Has a lightweight footprint.

What We Don't Like

The free version is limited in several important ways.

Bitdefender offers two security apps for the Mac a free Virus Scanner for Mac and the paid Bitdefender Antivirus for Mac. Both use the same Bitdefender engine for finding and removing malware, but Virus Scanner for Mac uses a manual approach to scanning your Mac, while Bitdefender Antivirus for Mac is loaded with features to make the process simple and, if you want to, as automatic as possible to ensure you are never the victim of a malware attack.

In fact, the Autopilot feature works so well that you can just about turn it on and forget about it, knowing that your Mac is protected from current and future threats from malware as well as ransomware, which is on the upswing in the hacking world.

Time Machine Protection monitors your Time Machine backups and prevents ransomware attacks that may try to encrypt or remove your backups.
Safe File allows you to specify folders that will be continuously monitored, preventing unauthorized apps from making changes to these folders.
Adware removal can free your Mac from annoying ads, unwanted browser add-ons, and browser toolbars that may be added without your consent.
Traffic Light browser extension works with Safari, Chrome, and Firefox to add advance phishing detection to your browser and warn you of dangerous websites.

Bitdefender makes use of traditional signature-based detection system as well as behavioral-pattern recognition. To help keep its database of devious malware types up to date, Bitdefender uses a cloud-based data collection system that stores the most recently detected Mac malware, adware, and ransomware information, allowing all Bitdefender users to have the latest updated detection system.

Malwarebytes for Mac

What We Like

It's always active and running to find threats.
Provides advanced options that can be tweaked to your desires.
Doesn't use up lots of memory or CPU.

What We Don't Like

The free version only works in manual mode (i.e., it can't catch malware automatically).

Malwarebytes for Mac has been a top choice for finding and removing Mac-based malware ever since its early appearance as Adware Medic.

Now under the guidance of Malwarebytes, the app retains its free ability to find and remove malware but has also expanded its capabilities to offer a premium paid version that can actively prevent Mac virus, spyware, and malware infections. It can also keep adware and unwanted apps from finding a home on your Mac.

Detects and removes adware targeting Macs without requiring a separate browser add-on.
Real-time protection can be disabled, allowing you to scan only when you wish.
Includes an uninstaller for removing the Malwarebytes app.
Low system overhead even with background scanning enabled.

Malwarebytes uses a signature-based system to determine the presence of Mac malware. The signature list can be updated as often as once per hour. Malware that is discovered can be automatically quarantined for easy removal at a later date.

of 04

Sophos Home for Mac

What We Like

Provides real-time threat detection.
Identifies and removes various types of malware.
Includes unique features such as remote management.
Protects against web threats via filtering.

What We Don't Like

Several features are not included in the free edition.
You must provide personal details to download the free version.
It has a relatively large setup file.

Sophos has been a leader in business-grade antivirus and security protection apps for PCs and Macs for years. Sophos brings the same business-grade security system to the personal Mac (there is also a PC version) user for free.

Sophos Home for Mac can protect every Mac in your home from malware, viruses, and ransomware. It also can protect your web browsing from stumbling across inappropriate websites that may contain phishing schemes or malware.

Sophos uses signature-based as well as heuristic-based behavioral detection to monitor the unusual behavior of apps to identify suspicious activity. Like most antivirus apps for the Mac, Sophos can detect Windows-based threats as well, helping to prevent cross-platform contamination.

Remote management allows you to monitor, configure and control Sophos Home on up to ten Macs or PCs.
Parental controls can block viewing inappropriate websites while keeping a log of such web visit attempts for later review.
Background scanning had a low impact on overall performance.
On-demand scanning allows you to initiate a scan at any time.

Apple Antivirus Software

Sophos runs primarily in the background scanning your Mac and detecting if malware or related threats are present whenever you download, copy, or open a file or folder. The scanner can also examine compressed files to make sure files contained within are safe.
