Choose the best antivirus for your Mac

Unlike with Windows PCs, there’s historically been little demand for antivirus software for Macs. Apple’s MacOS operating system has been built to withstand malicious attacks, and there have been comparatively few viruses written to target Macs.

However, Mac users could be exposed to a rise in viruses and malware in the future. With more Apple products being sold and Mac ownership on the increase, criminals are now actively targeting the Mac ecosystem.

Although it's missing some of the features we'd expect to see in paid-for software, it's still a great way to increase security on your valuable Mac.

Do I need Mac security software?

Even if the Mac operating system has traditionally proven resistant to virus attacks, there are still risks. If you use your Mac to go online, you’re still open to many of the same issues that affect Windows PC users, including spam emails, phishing scams, Trojan malware, browser vulnerabilities and ID theft. In fact, March 2016 saw the first example of Mac breaching ransomware.

Apple continues to keep its Mac operating system security beefed up. For example, its Gatekeeper tool can prevent you from installing anything other than Apple-approved or registered software. FileVault keeps your files safe from prying eyes by encrypting your Mac so it can only be used by an authorised user. Other MacOS security features include anti-phishing, privacy and parental controls.

MacOS now also includes App Sandbox, which keeps your apps separate from system components, so it’s easier to remove one app if it gets infected by a malicious program.

How to use the Mac firewall

Macs do not come with any antivirus or antispyware software, although they do have a built-in firewall. This, however, is turned off by default.

To turn the firewall on, go to Apple Menu > System Preferences > Security & Privacy, click the Firewall tab and click Turn On Firewall.

To configure settings to allow incoming connections from authorised sources, click Firewall Options.

Free antivirus for Mac vs paid-for packages

The best Mac antivirus software should be easy to use and eliminate all types of malware, even those designed for Windows PCs.

Free Mac antivirus software provides basic antivirus protection, but typically lacks the extras such as a firewall, identity protection, parental controls and email monitoring that you get with paid-for security suites.

For comprehensive protection, look for a security package that covers all the angles with antivirus, antispyware, email scanning, web protection and anti-phishing. Some programs include a two-way firewall and network protection. As viruses evolve quickly and new ones emerge daily, it’s best to look for software with an automated scanning and updating schedule.
