Do Mac computers need antivirus protection?

Think your Mac is invincible to malware? Time to update that notion. Gone are the days of Apple saying Macs don’t catch viruses. While it’s true that Macs have some built-in security advantages over Windows, hackers are turning their sights toward Apple. A shocking 2021 study revealed a 1,000% increase in Mac-targeted malicious programs. Don’t risk it; it’s time to add some antivirus muscle to your Mac. This post will guide you through the why and the how.

Do I need antivirus protection for a Mac?

Simply put, you need antivirus software on your Mac. They’re not the fortress you might think they are. Sure, Apple’s internal security measures are decent, but a quality antivirus adds an extra layer of protection. Plus, with the uptick in Mac-focused cyber activities, it’s not something you want to overlook.

Now that we’ve concluded the importance of using antivirus software on Macs let’s get into how we select the best providers for the task at hand. Check out our selection criteria below for more details:

3. Customer support: Help when you need it is paramount, so we select antiviruses with email, ticketing, live chat support, or a mix of each support option.
4. Malware scanning: We use inert and live malware samples to test the blocking capability of the providers we recommend.

How AV tools secure Mac computers

The first question to ask is, “Does malware exist on the macOS platform?”

The answer to that is yes, it does. While Macs have largely flown under the radar of cybercriminals in the past, that’s no longer true. In 2020 alone, 674,273 new Mac malware samples were discovered.

Yes, figures do suggest that Mac computers are less likely than Windows PCs to come under threat from malware. But just because the risk is lower doesn’t mean there’s no risk at all. Plus, the risk is amplified if you’re a business that runs multiple Mac computers.

Top 10 types of Mac malware detected 2020-2021

Even if you’re just using a Mac as a home computer, there are some good reasons to consider improving security:

• Macs are becoming more popular. Part of the allure of attacking Windows PCs is that the impact is so huge, with Windows having around 76 percent of the market share. But Mac’s rise in popularity certainly makes it a juicier target for attackers than in years gone by.
• Mac users are attractive targets. With Macs being a lot more expensive to purchase than Windows PCs, Mac users will typically be wealthier. As such, they are attractive targets for criminals, especially those looking to steal personal data, including financial information.
• Windows is becoming more secure. Macs used to have a big lead over Windows PCs in terms of security, making the latter easier to attack. The latest versions of the Windows operating system are more secure than ever before, closing the gap, and making them more tough targets. It would be less surprising to see malicious hackers turn their efforts towards Macs.
• Malware development is easier than before. In the past, attackers have had to rely on existing malware or develop their own (which required extensive expertise). These days, malware development is much easier. Cybercriminals can often make small tweaks to existing malware to create a custom threat.

The macOS operating system comes with built-in malware detection, which we’ll discuss in more detail below. This built-in detection feature is a nice-to-have, but with an increasing number of threats, there’s a higher likelihood that new malware could find its way onto your system before Apple updates its databases. These are referred to as zero-day threats, and are reason enough to consider installing some security software.

Note that even an antivirus can’t protect you against many attacks. For example, if someone tricks you into installing malware, it’s already too late for an antivirus to save you. Human error doesn’t distinguish between operating systems and Mac users can fall prey to scams just as easily as PC users can.

MacOS built-in malware detection

Mac software is based on Unix, which comes with its own security features. This is one reason Mac has remained relatively secure. Mac also provides built-in security measures to help combat malware, including:

• Gatekeeper: If software that hasn’t been digitally approved by Mac attempts to run on your computer, Gatekeeper will block it until you provide authorization for it to continue. Keeping your Mac updated will prevent attempts to bypass Gatekeeper and you should be very careful when authorizing applications.
• XProtect: The XProtect feature detects known malware and automatically blocks its installation. The feature is constantly updated with the latest malware signatures. It monitors for new malware infections (and strains), and if any are found, then XProtect is updated. These updates occur separately from system updates, so you don’t have to wait to be protected from new malware.
• Malware removal tool: In case malware finds its way into a system, macOS technology can remediate infections. Removal of known malware will occur with each system update.

Apple continues to patch security vulnerabilities with each subsequent update. It’s crucial that you install updates as soon as possible to keep your system secure. Macs provide automatic security updates, but you need to make sure they’re enabled. To check, simply follow these steps:

1. Click on the Apple icon found in the top left corner of your screen and then on System Preferences.
2. Select Software Update.
3. Select your update preferences by checking the tick boxes.

Best free antivirus software for Mac

As with most things in life, there’s usually a catch when a product is free. Security is not an area we recommend you cut corners on but if you really don’t want a paid solution, here are two free options.

1. Intego Mac Security X9: Intego is a solid option for Mac users for one simple reason: It was built from the ground up for Mac. In fact, Intego doesn’t make a Windows version of its app. It’s exclusively for Mac and offers real-time monitoring, automatic scans, file quarantines, firewall protection, and more.

2. Comodo Free Antivirus for Mac: Although the brand doesn’t have the same punch as others on this list, Comodo offers a fairly broad range of features for customers of its free service. These include real-time malware protection, scheduled virus scanning, quarantines, suspicious file removal, drag-and-drop and one-click scanning, and more.

Other tips for securing your Mac computer

While built-in and additional antivirus software can help, there are other things you can do to secure your computer. Beyond the unlikely event of a virus taking hold of your Mac, the most likely threats you’ll face are adware and spyware. The best way to avoid those and other threats is by taking basic but effective security steps:

• Enable your firewall: Your firewall is your first line of defense against potential security threats. To enable your firewall, select System Preferences > Security & Privacy, and go to the Firewall tab. To make changes, you’ll need to click the padlock symbol in the bottom-left corner of the window and enter your password. Then hit Turn On Firewall. For more advanced customization, select Firewall Options.
• Keep your computer close: This may sound obvious, but never let anyone else have access to your Mac or install files on it on your behalf unless you know you can trust them. Get into the habit of locking your device if you are ever away from it.
• Avoid opening unknown files: Never open email attachments or other files that you have received from unknown or dubious sources. Check the email and the name it appears to be coming from.
• Be skeptical of software providers: Only install software from reputable sites you know you can trust and avoid pirated software.
• Use strong passwords: Ensure your Mac, as well as all your local and online accounts, are protected with strong passwords made up of at least eight characters. Passwords should include numbers, letters (both upper and lowercase), and special characters. Test your password strength here.
• Keep your software up to date: Keep your Mac and applications up to date at all times. Get those updates through the developers’ sites or the App Store, not from pop-ups.

Many attacks on web browsers are enabled by JavaScript, and disabling JavaScript used to be good security advice. However, because of the amount of websites that will have their functionality affected on the modern web, this isn’t something we recommend for most people, despite the security benefit. You might opt for a browser extension instead that allows you to allow or deny JavaScript on a site-by-site basis instead. If you wish to disable JavaScript, uncheck Enable JavaScript in Safari > Preferences > Security.

If you practice all the above, you shouldn’t have to worry about threats disrupting your enjoyment of your Mac. Of course, things do change, so keep abreast of the latest security news just in case.
