Mar 23, 2020 What follows is the counter-argument as to why Macs don't need antivirus, but we still think it's better to be safe than sorry. Why Macs don't need antivirus (but aren't immune) All. Apple helps you keep your Mac secure with software updates. The best way to keep your Mac secure is to run the latest software. When new updates are available, macOS sends you a notification — or you can opt in to have updates installed automatically when your Mac is not in use. MacOS checks for new updates every day, so it’s easy to always have the latest and safest version.
The big question out there when it comes to Apple products is, “Can a Mac get a virus?” The short answer? Absolutely.

However, the initial version is limited, because it isn’t available for all apps just yet.At the moment, the ball is in the developer’s half. It’s the small things that make the difference between the Cupertino-based tech giant and their competitors and this option widens the gap.
Apple computers can get viruses and malware just like PCs can. While iMacs, MacBooks, Mac Minis, and iPhones may not be as frequent targets as Windows computers, all have their fair share of threats.

Adware, spyware, ransomware, and hardware and software vulnerabilities are some of the problems now affecting Macs, and not just PCs. Read on to learn more about some of the most common malware and viruses that can affect Apple devices, what the signs are, and what you can do to help protect your devices.
Four types of Apple viruses — and a vulnerability
Apple viruses can range from annoying to outright damaging.
1. Adware on Macs
Adware is a potentially unwanted program that can bombard users with advertising pop-ups. Adware can be both malicious or benign. Some adware can work in conjunction with spyware, a type of software that can spy on and record everything you do online.

Apple has frequently said that Macs don’t get infected by viruses. This is true, but not because macOS is inherently better than Windows. While the operating system does have some protections that can make viruses less powerful, that doesn’t mean macOS is airtight. And while Macs are rarely targeted by viruses, it pays to be careful. Reputable malware scanning software or antivirus software is a good addition to any secure system.
Do Macs Needs Antivirus Software?
Macs aren’t immune to viruses, but they also aren’t typically targeted by attackers. The platform simply doesn’t have a large enough user base to make it worth the time for attackers to custom-build specific attack packages for the operation system’s unique features. The Unix-based macOS operating system is fundamentally different from Windows in a number of ways, meaning that any attacker hoping to infect Macs would need to create custom code tailored specifically to the operating system. Furthermore, macOS runs in a sand-boxed environment, making it more difficult for errant programs to take control of your system.
Since Macs still represent only a sliver of market share, an enterprising hacker would get more bang for their buck by focusing on the most popular operating systems. Like spam and phishing attacks, virus distribution relies on the law of large numbers. Without a specific target, attackers will get the greatest benefit by distributing compatible malicious code to as many computers as possible. This increases the likelihood that they’ll encounter a vulnerable system, improving the odds that their attack will succeed.
While any computer can benefit from the protection of well-made and updated antivirus software, it’s not an essential operating requirement for Macs. This has lead to a couple of insufferably smug ads from Apple on the topic, which is sort of ironic. If the Mac was more popular, the machines would likely need more robust antivirus protection.
Do Mac Viruses Exist?
Mac viruses definitely exist. Back in 2014 a hacker used the iWorm malware to create a nearly 20,000-member botnet. The Flashback vulnerability in Java of 2012 affected more than 500,000 Macs, so many that Apple was forced to issue a security update to OS X Lion and patch the vulnerability. More recently, the KeRanger encryption malware was distributed inside a popular BitTorrent client for macOS. And according to antivirus vendor Malwarebytes, Mac malware has increased by 230% over 2016. Macs certainly can get viruses, and Mac-specific viruses do exist. They’re just less common than the Windows equivalent.
Are Macs Vulnerable to Other Attacks?
The thing with viruses is that they’re probably the least popular form of computer attack vector these days. Far more common are things like phishing attacks to crack email accounts and siphon password resets. And while Macs don’t require antivirus software, they’re still vulnerable to these attack vectors. This includes email-based phishing attacks or browser-based cross-site scripting or man-in-the-middle attacks. And potentially unwanted programs (PUPs) like Mac Defender are voluntarily installed by the user but include malicious features and can’t be easily removed. Even if they’re unlikely to get viruses, Mac users must still practice safe browsing habits.
What Antivirus Software Should I Get?
For security-conscious users, there are several reliable options for macOS antivirus software. It’s not mandatory, but an ounce of prevention is worth a pound of cure.
Bitdefender: this antivirus software stands at the top of AV Test’s antivirus rankings, blocking 100% of threats in those tests. It also has little impact on your system, so you won’t see slowdowns while scanning or during real-time protection. It’s also not cheap, clocking in at $40 for a license.

ClamAV: Windows or Linux users might be familiar with this open-source, multi-platform suite for detecting viruses and malware. It’s long-lived, well-respected software, and it has a great Mac version. This is definitely the choice of system managers, programmers and power users.
Computer Security Software For Mac
Sophos Home: This free consumer version of the Sophos enterprise security software works in Windows and macOS. In addition to detecting viruses and malware, it also protects against web-based attacks in real time. It’s a stepped-down version of enterprise software, so it might not run perfectly on a home environment.
Malewarebytes: Another much-loved malware detection tool for Windows, Malwarebytes also offers a Mac version. It’s fast, with a focus on real-time protection rather than scheduled scans. It sports a great reputation for removing PUPs, but it won’t scan macOS for Windows viruses. This makes it less of an antivirus program and more of an anti-annoyance program, and it’s great for home or individual users.
Apple Mac Security
Avast: Avast’s free software detects viruses and malware. It also proactively protects against web-based threats like unsafe websites and email attachments. Unfortunately, it’s also known for imposing a heavy load on system resources to offer these real-time features. You’ll probably want to avoid this one, but it’s worth mentioning because it’s so widespread.
