Best Mac Antivirus Software (Updated March 2018)

If you own a Mac and you want to keep your computer safe, you need Mac antivirus software. In this Best Mac Antivirus 2018 article, we’ll explain to you exactly why you need it and also how Macs are vulnerable to viruses and ransomware.

Do you need virus protection on a Mac?

macOS is a Unix-based OS, which is important for security reasons because it means its sandboxed. This keeps threats localised on your computer and prevents the ability to spread infections easily. However, it doesn’t completely protect Macs from viruses and Malware.

Macs are susceptible to viruses just like PCs are. The reason they don’t get as many is simple, there aren’t as many Macs in the world as there are PCs. This means the reward for creating malicious Mac malware isn’t as big. Add in the fact it’s harder to infect Macs en-masse, because they’re sandboxed, and you start to understand the economics behind why Macs are generally safer than PCs.

But Macs do get infected by malware. One of the most famous infections to strike Macs in recent years is the KeRanger Trojan. While it wasn’t the biggest of attacks, the simplicity of how the software was installed onto Macs is alarming. Hackers gained access to legitimate websites and replaced downloadable DMG files, with infected files. This meant users downloaded, installed and gave computer permissions to what they thought was a trusted program.

Best Mac Antivirus: Do Macs need antivirus?

Yes. Many people will tell you the opposite, of course. And it is true that the threat is much less urgent if you are a Mac user than those Windows-using clowns. But if you have a Mac you care about, and it is connected to the web, you ought to install security software.

Macs are less vulnerable than are Windows PCs and laptops for two reasons. Firstly, there are fewer Macs. All cybercrime is based on plucking low-hanging fruit, so the much larger group of Windows users in the world is a much bigger target. That may change, however, as the Apple user base grows. Lest we forget, Macs are expensive so Apple users are a lucrative target.

Which brings us to the other point: Macs are harder to attack than are Windows PCs. That’s because the Mac OS (previously OS X) is a UNIX operating system, built in the dim-and-distant past on a UNIX derivative. This means that it is sandboxed. Unlike a Windows PC or laptop, if a crook infects a Mac in one area, they can’t get it all. Not easily, anyway.

This makes Macs less attractive to hackers. But that is a long way from making them invulnerable. So if you value your computer and the information on it, get yourself some security software. These are the best.

We base our ranking on the most recent AV-Test group review of Mac antivirus products, as well as price and ease of use. The tests look at efficacy in terms of detecting and destroying known and unknown web threats, and the impact each program has on system performance. We’ve split the best Mac antivirus products into those you pay for and free Mac antivirus. In general, the best free products offer high levels of protection but tend to have a greater negative impact on system performance when compared to their paid brethren.
