Best Antivirus Apps for Mac

Contrary to popular belief, the macOS operating system is actually as vulnerable to malware as Windows. The Windows platform is more common, so many virus writers create their malicious software specifically for it.

The macOS is by no means flawless and is constantly the subject of close attention of cybercriminals, especially now when Apple sales go up. Yes, it is still hard to infect Apple devices with real devastating viruses, but malware like A.akamaihd.net is a fairly common thing.

So, Mac owners should think about their own security and install antiviruses. Fortunately, there are many effective, and most importantly, free security solutions that can counteract not only already known threats, but also various new viruses, unwanted adware, and dangerous file encryptors like ransomware.

Although most antivirus solutions function in the same way from a security point, these programs often have their unique methods of execution and features. Moreover, some security software pieces work better on Windows devices than they do on Macs. It means users need a Mac version of the program that is best suited to protect and clean Macs.

Besides, when dealing with antiviruses, CPU usage remains of the largest concerns. A great Mac antivirus software should work perfectly well while consuming very little CPU resources and should not slow down your computer.

Beware, that there are many fake antivirus programs on the market that do not clean or protect Mac devices. They are created just to scare computer users and make them pay money. These fake antivirus tools in fact act like a virus. They show fake alerts that are very annoying. Actual legitimate antivirus software will not do that. 

All Mac antivirus applications that we recommend are legitimate apps designed by reputable software firms. They are also regularly tested by several independent antivirus testing labs, review websites, and independent users. Below is a selection of the five best free antiviruses for macOS.

Although Malwarebytes for Mac was originally promoted as a solution to get rid of adware, over time, this app has become a full-fledged antivirus.

Why do users need antivirus for Mac?

The Internet is full of the webpages where tons of users ask the same question again and again: “Can macOS devices be infected with malware or viruses?” So, you are not the only one to ask this question.

According to DigitalTrends, the answer to this question is definitely – yes. DigitalTrends asked several malware experts, and they told the online magazine that there are many macOS security incidents, and there will be even more.

Based on data from CVE details, macOS is currently the 4th most vulnerable OS. It appears that the Mac operating system has more vulnerabilities than Windows, even including old and terribly unsafe Windows 7 and Windows Vista.

Malware attacks on Macs rises a jaw-dropping percentage each year. The increase comes primarily from adware bundled installations. Many of such rogue malware pieces are not dangerous and can be removed quickly. But it adds to the fact that the common belief that Macs are virus-free is not true anymore.

Netmarketshare says that about 9 percent of all computers are running macOS. This number is quickly growing but still represents only a small portion of all devices as Windows takes 88 percent. So, although, by percentage, macOS makes up a tiny group of desktop devices getting viruses, this is due to smaller market share rather than Mac’s better security.

On the other hand, macOS uses sandboxing. It is harder to infect your system and spread the virus throughout it. Also, tools to create Mac malware are rare. They are not as readily available as for Windows. And it is difficult to create such tools. Malware authors need more money and time to create such malware. So, Macs avoid getting viruses as there is less chance for hackers to return a profit. Looking from a broader perspective, there are more than 400 million Windows users and 100 million Apple users. For hackers, creating and spreading Windows malware has a higher chance of turning a profit.

Nevertheless, 100 million users is a big number. For some hackers, it is a sphere where there are less competition and more opportunities. Such virus creators are taking advantage of Mac user naivety who are used to the fact that they do not need to be afraid of malware.

Do I need a Mac antivirus? The correct answer is – yes. Every Apple user must have antivirus software on their device. And the next question that appears is what is the best antivirus for Mac, and what features should be taken into consideration while shopping for a Mac antivirus app.
