7+ Best Antivirus Software for Macs in 2018 (Free + Paid)


If you use a Mac for business, you need to keep it secure. Even if you use your Mac for personal use, if you do a lot of financial transactions online, you may still wish to protect your computer. Here's what you need to know about antivirus software for the Mac.

The number of malware and virus attacks has increased in recent years. According to a recent McAfee Labs Threat Report, which researches and compiles threat statistics based on a sample database, there were over 700,000 incidents of Mac Malware attacks in the fourth quarter of 2017 alone.  The findings were confirmed by a number of other antivirus software labs including Sophos labs, which predicts significant continued efforts to infect Mac computers in the coming year.

To keep your computer from being compromised, antivirus software for your Mac can be an important part of your Mac security software. In this article we've rounded up some of the best security software for Macs, including both free antivirus software for Macs and premium Mac security software.

Do Macs Need Antivirus Software?

This is a complicated question and there's no one answer. 

Conventional wisdom has long held the Macs are secure and don't need antivirus software. Many people would say that this is still the case. While it's true that historically Macs have been more secure than PCs, the risks for Macs are increasing.

Macs are more secure than PCs due to their Unix-based operating system, which makes it more difficult for a virus to infect a Mac. Also, OS X 10.7.5 and later includes a default Gatekeeper security feature that's meant to keep users from downloading software from untrusted sites.

But malware is getting more aggressive—even for Macs. Some common type of threats to  computers are:

  • Ransomware. This malware keeps you from accessing your machine until you pay for access to be restored.
  • Adware. This causes unwanted and unwelcome advertisements to display on your computer. It may also include spyware.
  • Spyware. This malware collects data by recording how you use your Mac. It can record keystrokes, track online activities, and at times even take control of your computer.
  • Phishing. This is an attempt to gather your personal data, often through a malicious website or an email scam.
  • Cryptojacking. This new type of malware uses your computer without your permission to mine cryptocurrency.

While attacks on Macs are still less common than attacks on PCs, some of these threats are now targeting Mac operating systems. A common way for a Mac to get infected is by downloading software that contains malicious code from an unverified or untrustworthy source. Even though the newest versions of macOS have the Gatekeeper security feature that's meant to protect you from downloading Malware and other malicious software, that feature can be turned off or overridden. The effects of being infected by malware range from a loss of use of your system to data loss to simply slowing your system down.

With all this in mind, you should make your decision about whether to use antivirus software on your Mac carefully. In my opinion, if you're using your Mac to run a business where you store sensitive data that could be compromised, or if your business would suffer if your Mac became unusable, then it's better to be safe than sorry. The answer as to whether you need antivirus software is probably "yes."

Best Mac Antivirus Software

Let's take a look at some of the best antivirus software for Macs. Most of these packages will work well for solo professionals or small to medium businesses. Several of these software companies also offer security software for larger businesses.

Note: Many of these companies offer both Mac and Windows antivirus software, however, the focus of these overviews is on the Mac software.

Here are the Mac Antivirus software packages that consistently receive high ratings:

1. Sophos Antivirus for Mac

How to Keep Your Mac Secure

Mac Antivirus software is just the first step in keeping your computer secure. Whether you're using your Mac for personal use or business use, your information is important. The following actions can help your Mac to be more secure:

1.  Make Regular Backups

Back important information up regularly. Also, store backups securely—cloud storage can be a good option. 

2. Create Strong Passwords

Make sure to follow good password creation guidelines. Avoid using passwords that can be easily guessed such as the name of a family member or the street you live on. Also, don't use the same password for every login. Make sure that your passwords use upper and lower case letters, numbers, and symbols. Finally, change your passwords regularly.

3. Use Two-step Verification

Where it's available use two-step verification. Two-step verification requires you to provide more than just a password to access your information. Typically, you'll be sent a code through email or text message after entering your password. 

4. Don't Connect to Unsecure Networks

It's becoming popular for Wi-Fi to be available almost anywhere. But not all of those public Wi-Fi connections are secure. Even worse, criminals sometimes set up fake Wi-Fi hotspots in public locations for the sole purpose of gathering your information.

5. Keep Software and Operating System Updated

Software and operating systems are updated for a reason. Sure, sometimes it's to introduce new features, but often the main purposes of updates is to patch security vulnerabilities. If you don't update your OS and software, you could be leaving yourself open to a cyber-attack.

6. Only Download Software from Trusted Sources

Make use of the macOS Gatekeeper security feature, don't bypass it. Be cautious about downloading software from companies you've never heard of—even if the software is free. Likewise, be careful about clicking on links in emails you receive. Look for reviews on the software that you're planning on downloading to see what experiences others have had with it. If the software checks out, make sure that the website you're going to load the software is the legit site and not a fake. 

7. Use Antivirus Software for Macs
