Bitdefender Total Security 2018 comes bundled with separate programs for PC and Mac computers, and for Android and iOS mobile devices. The program protects against malware on all these devices, though we found its virus scan causes some slowdown on Mac computers. The Best Computer Protection Software of 2018 We spend hundreds of hours each year testing dozens of computer protection programs to find the best ones on the market.

Norton Security Standard is compatible with both Mac and Windows computers, so it’s ideal if you have computers running different operating systems that need virus protection.
In partnership with Norton

After all our testing and research, we feel Bitdefender Antivirus for Mac is the best antivirus protection for Mac users. It does a good job detecting and protecting against threats, including Windows malware.

It has extra security tools like a VPN, and it doesn’t cause your computer to slow down. For Windows computers, we found Bitdefender Antivirus Plus 2019 to be the best antivirus security software.

Why trust us on Mac Antivirus software?

We spend most of the year testing internet security programs, including antivirus software for Mac. We devote hundreds of hours to downloading, using and testing the most popular security programs on multiple devices running different operating systems, including Mac OS, Windows 10, Windows 8 and Windows 7. We test programs that are compatible with mobile operating systems as well. All this helps us understand just how each program works and if any slowdowns, quirks or tools affect performance on each device.

As part of our testing methodology, we research the standards of the Anti-Malware Testing Standards Organization (AMTSO) and follow several of these suggestions. The most important standard is to maintain unbiased. This means we don’t talk with program developers, representatives or vendors during testing, and we either purchase each program or download the free trials from the program’s website to make sure the software we are testing is the same version users get rather than one that may have been tampered with to create a more favorable outcome.

We have developed relationships with several experts in the internet security industry, including security analysts, IT technicians and cybersecurity managers. We also follow security blogs and news outlets, receive monthly newsletters from manufacturers, attend trade shows and do all we can to stay on top of new developments and security breaches within the industry. Devoting this much time over the last 15 years has helped us become a leading expert in antivirus and internet security practices. This is why you can trust us when it comes to the best antivirus Mac software.

1. Bitdefender Antivirus for Mac: best overall

Bitdefender Antivirus for Mac

Blocked 99 percent of the live threats we used and scrubbed most of them from our system automatically

Reasons to Buy

Reasons to Avoid

When we tested Bitdefender Antivirus for Mac, it blocked 99 percent of the live threats we used and scrubbed most of them from our system automatically. It also did a decent job recognizing Windows threats so they wouldn’t be accidently sent to a PC user.

The vulnerability scanner looks for outdated software then gives you a trusted link where you can download the latest patch or version. This helps cover any weak spots where hackers and ransomware could infiltrate your computer. Bitdefender warns of malicious websites with its safe browsing feature, and it scans USB drives to stop any threats from infecting your computer at that point. It is also one of the only programs that includes a VPN that hides you while online so adware and other trackers can’t see your search history or which sites you visit. The biggest drawback is Bitdefender isn’t the easiest program to set up or use. There are some tools and features that can only be accessed through the online portal while others are only found on the dashboard.

2. AVG AntiVirus for Mac: best free Mac AntiVirus

AVG AntiVirus for Mac

AVG AntiVirus for Mac is an extremely budget-friendly Mac antivirus solution

Reasons to Buy

Reasons to Avoid

This simple program offers great virus protection, doesn’t slow down your computer and includes a few additional internet security features. It is also free for home use.

This software scans incoming email and anything connected to the USB port, including mobile devices, and removes any threats it finds so your computer isn’t infected. It also scans for outdated software since this is one of the biggest ports of for ransomware and hackers. AVG has phishing blockers and spam filters that keep threats in emails from downloading to your computer or directing you to dangerous sites designed to gather personal information. It is one of the easiest programs to use, with large icons for each tool. Because it is a free program, AVG does have in-program ads that can be distracting. It also requires the vulnerability scanner to be installed separately from the antivirus program, though once it’s installed you can access it from the program dashboard.

3. Norton Security Standard: best for multiple devices

Norton Security Standard

Norton Security is the best antivirus software if you have computers that run different operating systems

Reasons to Buy

Reasons to Avoid

It offers the same level of protection to both Mac and Windows machines, easily detects threats on both, and even detects and removes some Windows malware hidden on Mac machines.

Norton Security Standard scans email and USB shared files to make sure they don’t have hidden threats that may infect your Mac. It also looks for out-of-date software that may create a weak spot that hackers and ransomware can use to infect your computer. The antivirus program for Mac includes a password manager and banking tools to shield your important information from identity thieves, keyloggers and other internet tracking programs. The biggest drawback is Norton costs significantly more than other programs and charges a fee for each device you want to protect.

4. Intego Mac Internet Security

Intego Mac Internet Security

It’s designed to look, feel and work similarly to other Mac system programs like Finder or Safari

Intego Mac Internet Security does an excellent job detecting and protecting against Mac threats including viruses, Trojans and ransomware. It’s designed to look, feel and work similarly to other Mac system programs like Finder or Safari, so it isn’t too difficult to figure out. Along with ContentBarrier, the program that protects against malware, Intego Mac Internet Security also comes with NetBarrier, a personal firewall that secures your computer against anyone trying to steal your internet which slows down your speeds. Any cellphones, tablets or other mobile devices attached to your computer through its USB ports are scanned by Intego to make sure there aren’t any threats that can infect your computer as you transfer files. Because it isn’t a premium security program, Intego Mac Internet Security doesn’t come with parental controls or a system vulnerability scanner, but you can purchase these separately.

5. Sophos Home

Sophos Home

During our tests Sophos wasn’t very effective at protecting against Mac malware

We know many Mac users look at Sophos Home as a cost-effective solution since its basic program is free. However, during our tests Sophos wasn’t very effective at protecting against Mac malware, and it is very difficult to figure out how to use. It only detected 78 percent of the threats we unleashed during testing, and a few threats we had to manually remove after following the online instructions from Sophos. But these instructions included disabling the automatic virus protection, which triggered Sophos to reboot. Once we reopened Sophos, the virus protection was on again and we couldn’t continue through all the steps of removing the threats. Ultimately, we gave up, uninstalled Sophos and installed another program to find and scrub our Mac clean of threats. Sophos did a good job of identifying and blocking Windows malware on our Mac machines.

Do I need antivirus software for my Mac?

The short answer is, yes, you do need antivirus software for your Mac. While Macs are less susceptible to viruses thank Windows computers, Macs are still at risk.

We conduct our own in-house tests using 165 of the nastiest Mac malware to find the antivirus programs that protect Macs best. These threats were tucked inside a zipped file that, when opened, downloaded the files and let them loose. We looked at which point each virus scanner picked up the threats, including Trojans and ransomware, and if the program automatically removed them or placed them in a quarantine folder for us to take care of later. Most of the Mac antivirus programs caught the threats as the files opened and deleted them immediately. Some programs moved each threat into the quarantine folder while others quarantined just those threats that were created to look like legitimate programs. This gave us a good idea of how well the programs protect Mac computers. It also is a good way for us to evaluate how much of our computer’s resources are used while running. During virus scans we perform common tasks, such as sending email, browsing the web, watching movies and playing online games and look for any lag, buffering or slowdown that may be caused by the antivirus software.

While testing we look for how easy the program is to download, install, set up and use. We feel this is important since many users aren’t computer savvy, so an easy setup process ensures that all a program's tools are in working order.

How much does antivirus for Mac cost?

Because Mac antivirus solutions are basic programs without many tools beyond malware protection, you can expect to pay between $30 and $40 for a single user license. Some programs, like F-Secure SAFE, come with a minimum of three licenses to protect multiple computers or laptops at once. There are a few free programs available, but they generally don’t recognize as many threats – plus they bog down your computer and have lots of annoying pop-up ads. If you want more protection with parental controls, a personal firewall or a password manager, check out Mac internet security suites that typically come with these extra tools for around $50.

Which antivirus is best for Mac?

Bitdefender Antivirus for Mac, Trend Micro Antivirus for Mac and Kaspersky Internet Security for Mac are all great Mac antivirus programs that proved in our lab tests they are excellent at detecting, blocking and protecting against malware, including Trojans and ransomware. Because the most important function of antivirus for Mac is protecting against malware, Top Ten Reviews invests considerable time testing each program using live threats, so we can tell you exactly how the program works and how well it detects and blocks malware.

Windows threats don’t affect Mac devices, but we still test how well Mac antivirus tools detect these threats because they can hide among your files and accidentally be sent on to a PC through email or file sharing. Avast Security for Mac, AVG AntiVirus for Mac and Trend Micro all do an excellent job of detecting both Mac and Windows malware on Mac computers.

After protection, the biggest differences among Mac antivirus solutions are security features. Detection features are where and what the antivirus program scans on your computer. All of the leading programs scan USB drives and incoming email. Some Mac antivirus software includes a system vulnerability scan that looks for weak points in your computer, typically out-of-date software, and prompts you to install the latest version to strengthen those points. Programs such as Bitdefender present you with a legitimate link where you can download newer software rather than chance downloading a malicious link.

Extra security tools include parental controls that let you set up time limits or block family members from accessing dangerous websites. Password managers shield your username and password from key loggers as you log into email, bank accounts and social media pages. And safe banking tools protect you from identity thieves as you bank and shop online. These aren’t typically included with basic antivirus programs but are included with Mac internet security suites.

Mobile protection isn’t included with antivirus programs, but a few solutions, such as Intego and ESET, will scan your mobile phone or table for any threats and remove them if the device is connected to your computer through a USB port.

How do I remove viruses from my Mac?

The hardest part of cleaning a threat from a Mac computer is finding what the malware is called and where it is hiding, especially since there are sophisticated viruses that look and function like a legitimate app. There are sites that list common Mac malware and where they can be found using the Activity Monitor on your iOS. Once the threat is located, the next step is to stop the malicious application from running and quickly move it to the trash bin. This will keep the program from restarting. If there are any other folders or files that were installed along with the malicious application, make sure these are placed in the trash too; otherwise these files will continue to drain your computer’s resources and cause frustration. When you empty the trash bin these files will be permanently removed.

An easier way to ensure you quickly find and remove Mac viruses is to use an antivirus program like Bitdefender Antivirus for Mac because it not only locates malicious apps and files, but automatically scrubs them from your computer for you. On top of that, because Mac antivirus programs are paid for through a yearly subscription, you can keep the program installed and use it to prevent a malware attack in the future.

Kaspersky Total Security

Bitdefender Antivirus Plus

Norton 360 Deluxe

All Windows systems need antivirus software, even if it's free antivirus software. The Windows Defender software built into Windows 10 has gotten much better, but it still can't quite match the best third-party paid offerings. We believe it's worth paying for Windows antivirus software because you'll get the best protection coupled with the latest updates and the most useful features.

Our top pick overall is Kaspersky's Windows antivirus lineup, which combines excellent malware protection with a moderate system impact, a full slate of extra features (such as a hardened web browser, webcam protection and file encryption) and an easy-to-use interface.

Right behind it are Bitdefender, whose cheapest paid product is the best bargain in antivirus software, and Norton, which offers excellent protection with optional identity protection. Trend Micro and McAfee also have very good malware protection, but had a heavier impact on system performance; ESET's protection is a half-step below the rest.

— All versions of Kaspersky antivirus software for Windows released since the fall of 2015 inadvertently let websites track users, a German journalist discovered. ADVICE: Kaspersky has patched the flaws, so make sure your Kaspersky software is up to date.

— A flaw in Bitdefender Antivirus Free Edition permitted full-system takeover. ADVICE: BItdefender has patched the flaw, so make sure your software is up to version 1.0.15.138.

The best Windows antivirus software overall

Reasons to Buy

Kaspersky's Windows products have excellent malware-detection scores and a light-to-moderate system-performance impact, the two most important criteria in our rankings. The basic program, Kaspersky Anti-Virus, has dedicated ransomware protection, a virtual keyboard and a convenient online account portal. But at this price level, it's beaten by Bitdefender Antivirus Plus, which has even more features.

Kaspersky Internet Security is our top choice among the midrange packages. It has parental controls, a secure browser, anti-theft protection for laptops, webcam protection and a VPN client that kicks in when you connect to an open Wi-Fi network. It also includes software for macOS, Android and iOS.

The premium antivirus suite, Kaspersky Total Security, adds backup software, file encryption, a file shredder and a password manager. It's our favorite among all the premium security suites.

Strong protection on the cheap

Reasons to Buy

Bitdefender Antivirus Plus is our top choice among basic antivirus products. It has nearly perfect malware-detection scores and a very light system performance impact, and it also offers the most value, with a password manager, a secure browser, VPN client software, a file shredder and protection against encrypting ransomware. It also automatically stops scans if it senses you're playing a computer game.

The midrange Bitdefender Internet Security adds parental controls, file encryption, webcam protection and a two-way firewall, while Bitdefender Total Security tops off the lineup with an anti-theft feature for laptops and a system optimizer. The best deal is the Bitdefender Family Pack, which puts Total Security on up to 15 devices for (a frequently discounted) $120 per year.

Reasons to Avoid

All of Norton's antivirus products offer excellent malware protection, and the once-crushing system-performance load is now much lighter. But Norton's packages come with fewer security features than competing products, even after a recent overhaul that resurrected the old Norton 360 nameplate and added identity-protection options and unlimited VPN service.

The bare-bones Norton AntiVirus Plus has a password manager, but no webcam protection. You'll get that, plus a VPN client and more online storage, with the otherwise identical Norton 360 Standard. Norton 360 Deluxe adds parental controls and licenses for up to five devices, plus more online storage.

For an extra $50 per year, you can gets Norton 360 with LifeLock Select, which adds LifeLock identity protection plus even more storage space. Topping out the list are Norton 360 with LifeLock Advantage and Norton 360 with LifeLock Ultimate, which expand the identity-protection services but offer the same malware-protection features as Norton 360 Deluxe. If you're looking for just an antivirus solution, however, even a midrange Bitdefender or Kaspersky package will give you more useful security tools.

Best Computer Security For Mac

Trend Micro offers very good malware protection, but its detection engine creates a heavy system-performance impact. Its entry product, Trend Micro Antivirus+ Security, is pretty basic in terms of extra tools. Parental controls and a system optimizer and file shredder come with the midrange Trend Micro Internet Security. The top-end Trend Micro Maximum Security adds a password manager, a secure browser and file encryption, but none of Trend Micro's programs include a two-way firewall.

McAfee's malware detection has improved greatly in the past couple of years, but it still slows down PCs a lot during scans. Despite that, McAfee AntiVirus Plus is a bargain; $60 per year buys software for up to 10 (in fact, it's unlimited) devices, whether they run Windows, OS X, iOS or Android, and the software comes with a file shredder and a two-way firewall. (A single-device license costs $40.)

McAfee Internet Security adds one of the best password managers in the business, but to get parental controls, you'll have to spring for the 10-device license of McAfee Total Protection or its sibling McAfee LiveSafe, which comes pre-installed on many new PCs. The multi-device licenses of those two security suites also come with an identity-protection service, but none of the McAfee products have a secure browser or webcam protection.

Nothing fancy

Reasons to Buy

Reasons to Avoid

ESET is one of the biggest antivirus names in Europe, but while it has a moderate system-performance load, its malware-detection rate isn't as spectacular as those of the other antivirus brands on this page. The entry-level ESET NOD32 Antivirus is easy to use but has few useful extra tools. ESET Internet Security adds a network scanner, webcam protection, parental controls and a hardened web browser.

The top-billed ESET Smart Security Premium tosses in file encryption, a virtual keyboard and a password manager. To get software for multiple platforms, you'll need the ESET Multi-Device Security Pack, which oddly offers the midrange Windows product instead of the premium one, but does include antivirus software for Linux.

Antivirus Buying Tips

The truth is that any of these six brands will protect your computer from infection very well. But before you buy antivirus software, you have to figure out what you will use it for.

If you have children at home, then you'll want to consider the various brands' midrange antivirus products, most of which include parental controls. Do you want an all-encompassing security solution? Many of the top-priced, premium products include backup software and VPN accounts. Or are you a techie who understands the risks? A low-priced basic program might be all you need.

Then you'll have to determine how many machines you need to protect. Got a single, solitary PC? Most vendors offer single-device licenses. Got a desktop, a laptop, a tablet and a smartphone? Multi-device, multi-platform licenses are available for most midrange and premium packages. Does your whole family need to protect its devices? Some vendors offer plans that cover 10, or an unlimited number of, devices on multiple platforms.

But the days when you could walk into a store and pay a one-time fee for an antivirus product are long gone. All the vendors now sell their software licenses as yearly (or multiyear) subscriptions. You'll always be getting the latest software, and you can download and install the software straight from the internet. But you'll be paying again every year.

Antivirus Pricing and Features

You don't have to spend a lot for antivirus software. Many products are sold online for much less than their list prices. But each brand offers at least three configurations of features and pricing -- basic, midrange and premium -- with every step up adding more features to the one before.

Best Computer Protection For Mac 2018 Collections

Think of antivirus packages like cars at an auto dealership. You can get a base-model Toyota Camry that has few extra frills but will get you from place to place just fine. For a few grand more, you can buy a Camry with satellite radio, but no heated side-view mirrors, alloy wheels or in-car Wi-Fi hotspot. Or you can spend a lot more to get a loaded Camry with all the fixin's.

Like automakers, antivirus makers hope you'll spring for extra options, whether you need them or not. The one thing you can't trade up to is a bigger engine -- all the Windows antivirus products in a given brand's lineup will use the same malware-detection engine and provide the same level of essential protection.

The basic rung of antivirus software is usually just called 'Antivirus' or some variant of that, and list prices for subscriptions are $40-$60 per year per PC. The software will have essential malware protection and possibly a few extra features, such as a password manager or a two-way firewall. Bitdefender Antivirus Plus provides the best bang for the buck at the basic level, with more useful features than rival brands' products.

Midrange antivirus software packages are frequently nameplated as 'Internet Security.' They generally add parental controls, some of which are very good, plus a few other features such as webcam protection. Midrange packages more likely to come with multi-device licenses than basic antivirus products, and will often include antivirus software for Macs and Android devices. (The iOS 'antivirus' apps aren't worth paying for.)

Listed yearly subscription prices for midrange antivirus packages start in the $60-$80 range per machine, but you can pay less if you're patient as online prices will change. Our pick of the litter is Kaspersky Internet Security, which covers multiple platforms and has almost everything you'd want.

At the top of the heap are the premium antivirus 'security suites,' which toss in all the extra security tools an antivirus brand can offer, such as password managers, VPN client software, backup software, online storage and even identity-protection services. (Not every antivirus brand offers all of these tools.)

The idea is that a premium antivirus suite can be a one-stop shop for all your security needs. List prices for premium packages start at $80-$100 per year, but make sure those extra security tools you'll be paying for are tools you'll actually use. The password managers in security suites are often quite good, but the online storage can be paltry and the VPN services generally don't give you much data before you have to pay for more.

How We Test Antivirus Software

Our evaluations are based on four different criteria: malware protection, performance impact, extra features and ease of use and of installation. How good is the program at detecting and removing malware? How much do scans slow down the computer's performance? Does the program have any additional tools, and are they useful? Can you easily navigate, and easily understand, the program interface? Most antivirus programs have user-friendly interfaces, but we'll ding one if it's too hard to find important tools.

All of our Windows antivirus tests are performed on the same Asus X555LA laptop running the latest mainstream build of 64-bit Windows 10 home, with an Intel Core i3 processor, 6GB of RAM and a 500GB hard drive containing 36GB of files.

Free Virus Protection For Mac

To assess a program's impact on system speed, we use our custom OpenOffice benchmark test, which matches 20,000 names and addresses on a spreadsheet. The longer it takes the laptop's CPU to complete the matching task, the heavier the performance impact.

For malware-detection scores, we use the most recent available testing results from four independent testing organizations: AV-TEST in Germany, AV-Comparatives in Austria, SE Labs in England and our own labs in Utah. Each lab regularly subjects the major antivirus brands' products to stress tests involving hundreds of previously unseen pieces of malware and thousands of instances of known malware.

Editors' Note: Why We Still Recommend Kaspersky

Kaspersky antivirus products have been banned from U.S. government networks, which we can understand. Because the company is Russian, using its software would create an unacceptable risk for persons and organizations involved in national security and critical infrastructure.

Best Computer Protection For The Money

However, we think Kaspersky software is perfectly safe for home users. We've seen no evidence to convince us otherwise. Kaspersky researchers are well respected throughout the antivirus industry, and the company has publicly exposed Russian cyberespionage campaigns as well as American ones.
