Do Mac computers need antivirus protectionIf you’ve got an Apple iMac, MacBook, Mac Pro, or Mac Mini, you may be wondering if you need to install an antivirus program to remain safe and secure and protect against the range of threats you keep hearing about in the media. But then again, you may have heard that malware only affects Windows systems. So what’s the truth? As with most questions relating to security, the answer is not crystal clear, but this article will help you gain a better understanding of the topic.

Mac computers have long enjoyed a reputation for being essentially immune to viruses and other types of malware. However, while they are still much more secure than Windows systems, Apple Macs are still vulnerable to some viruses and other malware, and it’s a growing problem. Apple’s built-in security system does a reasonable job at keeping malware at bay, but you should still consider beefing up protection by installing antivirus software.

In this post, we discuss why you need to consider using antivirus with a Mac computer and reveal some of the best antivirus software to help.

Do you really need an antivirus to protect a Mac?

In short, yes you do. Mac’s are not immune to malware and Mac-targeted attacks are increasingly prevalent. Following best practices for securing your device and using built-in security features can help, but an antivirus software can serve to protect your device even further.

Let’s explore this in more detail:

The first question to ask is, “Does malware exist on the MacOS platform?” The answer to that is yes, it does. Although Macs appear to be secure, there’s nothing to stop criminals targeting the software.

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

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 80 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, it follows that 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 difficult targets. It would be less surprising to see malicious hackers turn their efforts towards Macs.

Mac’s operating system does come 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 more threats, there’s an increased 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 all types of attacks. For example, if someone tricks you into escalating admin privileges to install 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.

Mac’s built-in malware detection

Information about built-in malware detection for Macs.

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

  • 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.
  • 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 does find its way into a system, MacOS technology can remediate infections. Removal of known malware will occur with each system update.

Mac 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. Open the App Store.
  3. Lastly, ensure that the tick boxes next to ALL the update options are checked, as seen in the image below.

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 will face are adware and spyware. The best way of avoiding 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, go to System Preferences > Security > Firewall.
  • Disable Java in your browser: Java comes with security flaws and is generally not needed. To disable Java, uncheck “Enable Java” in Safari > Preferences > Security
  • 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.
  • Avoid opening unknown files: Never open email attachments or other files that you have received from unknown or dubious sources.
  • 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 lower case), 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 popups.

If you practice all of 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.
