The Norton name has been synonymous with cybersecurity for decades. And while there was a period where its software was criticized for being bloated and slowing down computers, it’s improved a lot in recent years. If you’re looking for Mac cybersecurity, it’s likely to be one of the first solutions you think of. 

There are a few different tiers of Norton antivirus for Mac. Among them is Norton 360 Deluxe, a premium version with several advanced features. This gives you antivirus, anti-ransomware, a firewall, a password manager, parental controls and 50GB of backup space. Plus it protects your webcam privacy and monitors your email address to see if it’s been leaked on the dark web. 

On top of that, you get a VPN service for up to five devices and a junk cleaning tool. It really is the complete package for Mac security and privacy. But it’s not cheap. The first year is only $24.99, but that jumps right up to $104 a year afterward. If you just want a more basic package, Norton’s cheaper AntiVirus Plus may be a better alternative.

Despite negative reviews of previous versions, MacKeeper has come a long way in a short time. An intuitive, user-friendly Mac clean-up tool with a range of security features, MacKeeper is our favorite antivirus for non-techie users. MacKeeper detects and blocks adware, malware, ransomware, spyware, and viruses with complete protection in real-time.

Automatically scheduled to run every 24-hour, MacKeeper’s flexible scans allow you to scan an individual file, folder, or your entire computer, automatically removing any threats found. Unfortunately, MacKeeper does not view rootkits (tools used by hackers to gain control of your computer) as a virus, so you’ll need to use a dedicated rootkit removal tool to scan your Mac periodically.

One feature that stands out is MacKeeper’s ID Theft Guard. It enables you to quickly see what online accounts associated with your email address have been hacked. After the initial scan is done, MacKeeper monitors your email address for signs of identity theft, notifying you if your online credentials have been compromised.
Additional features: Adware cleaner, duplicate finder, ID theft protection, integrated VPN, memory cleaner, application update tracker, and many more.

Avast Security detects viruses, ransomware, and other threats in real-time. Still, advanced users may find the lack of access to granular features somewhat frustrating unless they bite the bullet and upgrade to Avast Premium Security at $69.99 (12-month plan) for one device.
For example, the free version detects ransomware but doesn’t stop it from corrupting personal files.

Despite its limitations, though, Avast is an excellent free antivirus and anti-phishing solution for macOS, with a built-in network scanner to detect security problems on devices within your network.


There were some allegations of Avast being involved in collecting and selling private data a couple of years back. But as a free antivirus solution with excellent lab scores, you can’t go wrong.
Additional features: Anti-phishing protection and Wi-Fi Inspector.

What to look for in Mac antivirus

There’s no point in having antivirus on your Mac if it can’t detect viruses. So you want security software with a good detection rate. Testing specialists like AV-Test track this kind of thing, so it’s worth looking at how different apps score in the latest round of tests. 

Aside from that, you should consider extra features. Some Mac antivirus solutions don’t have much more than the basic security, but others include additional features like VPN, password managers, junk cleaners and more. 

Price is important too. Unless you use a free antivirus app for Mac, you’re going to be paying for a subscription. These can vary massively, and some offer more features than others. If you can keep your costs down by leaving out features you don’t need, that might be worth your time. 

Finally, ease of use is a major factor in choosing the right cybersecurity for your Mac. Some apps are much easier to use than others, and a confusing interface can be a real pain. If you can, try out a free trial before committing to a full subscription. 

So which Mac antivirus is right for you?

All the security solutions we’ve looked at here will do a good job of protecting you. Which one you choose ultimately depends on your budget and what features you feel you need the most. 

The most important thing is that you have some kind of security in place. The days of Macs being immune to viruses are long gone. Cybercriminals are actively creating malware to attack Mac users, so you need to protect yourself. 

And, of course, you should make sure to follow best practice when it comes to things like choosing passwords. The more layers of defense you have, the better. 

Mac Antivirus FAQs

Do Macs need antivirus software?

In a word, yes. While it appears on the surface to offer adequate protection, Apple’s built-in antivirus, XProtect, is only designed to provide essential protection against widely known threats. It can’t compete with dedicated malware research teams and third-party antivirus apps. These provide comprehensive malware removal, scheduled system scans, and performance features such as cookie blacklists and cache cleanup.

What should I look for in a Mac antivirus app?

When choosing the best antivirus software for you, consider the protection it provides and the premium features that matter most to you. At the very least, your Mac antivirus software should include both scans and real-time protection against adware, malware, ransomware, spyware, and viruses. It should also police and block phishing attempts via plugins or extensions.

How do I purchase a Mac antivirus app?

Antivirus apps are typically purchased on a subscription basis, with discounts for paying a year in advance rather than every month. The good news is that many subscriptions allow you to install the software on multiple devices, so you can protect all Macs in your household with one yearly payment.

Can I use a free antivirus app for Mac?

Yes, you can, but choose carefully. Some free products are inadequate when it comes to protecting you fully, while others are designed to force you to upgrade to the paid version, to get additional features or more granular control. Of course, even free protection is better than no protection at all.

Does antivirus affect Mac performance?

All antivirus products affect Mac performance to some extent. Some are lightweight with minimal impact, while others are more resource-intensive. But the good news is that other than while running your first full scan following installation, it’s unlikely you’ll notice.
