Even as the first Mac virus threats appeared, they inspired counter measures. The first Mac antivirus programs were created in 1987 in response to nVIR and variants of nVIR. In addition, those of us sufficiently long in the tooth might even remember one of the most popular early Mac antivirus programs—a free utility named Disinfectant. As for virus protection there are few if any such animals affecting OS X. You can protect the computer easily using the freeware Open Source virus protection software ClamXAV. Personally I would avoid most commercial anti-virus software because of their potential for causing problems. For more about malware see Macintosh Virus Guide. Sep 26, 2019 The exploits require that you download and run malicious software for it to do any harm, and there’s no evidence that any Mac owners were directly affected. Meltdown and Spectre highlight the fact that even hardware outside Apple’s control can result in serious security exploits. Do not install any commercial 'anti-virus' software. It's all useless and can only cause problems. The Mac OS has built-in detection of Mac malware in downloaded files. The recognition database is updated daily. Although the protection isn't perfect, it's as good as you'll get.

An Apple Macintosh computer can get a virus or malware infection, so the short answer to the question is Yes. However, it's less likely for an Apple Macintosh computer to be infected compared to a MicrosoftWindows computer.

Note

The term 'virus' and 'malware' are often used interchangeably. For the sake of simplicity, 'virus' will be used on this page and refers to either a virus or malware.

Several examples of viruses that have infected Apple Macintosh computers include the following.

  • Flashback malware - Infected over 600,000 Apple computers in April 2012; designed to steal user's personal information, including account login credentials.
  • OSX/KitM.A virus - Infected a small number of Apple computers in May 2013; designed to take screenshots of a user's desktop and upload to one of several websites.
  • OSX.PROTON - Infected thousands of Apple computers in 2017; designed to steal user's account credentials by accessing the macOS Keychain app.
  • OSX/MaMi - Infected several thousand or more Apple computers in January 2018; designed to allow a person to view a computer's Internet traffic, also called 'snooping.'

In 2015, the senior e-threat analyst at Bitdefender, Bogdan Botezatu, was quoted as saying 'Mac OS X software has more high-risk vulnerabilities than all versions of Windows put together.' Despite that statement and apparent fact, Mac computers are still infected by viruses much less often than Windows computers. Below are some of the reasons why Apple Macintosh computers do not have as many viruses as Windows computers:

  1. Beginning with macOS X in March 2001, Macintosh operating systems are built on 'Darwin,' a fork of the BSDkernel.
  2. Most of the computer virus writers are more familiar with the IBM platform and Microsoft Windows, which means it's easier for them create a virus for that platform.
  3. Many of the tools, scripts, and code used to create viruses or other malware are designed for Microsoft Windows.
  4. Many of the targets of viruses are governments and businesses, with an aim to either steal information, money, or create havoc. The majority of computers used by government agencies and businesses have the Windows operating system, resulting in most viruses being targeted towards Windows computers, instead of Macs.
Note

If you are running a virtual PC on your Apple Macintosh or Windows in Bootcamp, because it is emulating Microsoft Windows, it can become infected with Windows viruses.

Software and plug-in threats

Although the Apple OS is more secure than many versions of Windows, additional software, plug-ins, and add-ons that connect to the Internet can introduce security vulnerabilities. The most common ways to attack a Mac computer is through a third-party browser and browser plugins, like Adobe Reader, Flash, and Java. Today, most Mac users have these plugins installed and enabled on the computer, and, in doing so, compromise the overall security of the system.

Additional security threats

Although a Mac is less susceptible to viruses, Mac users can still be the victims of trojan horses, phishing scams, and online fraud. If you are a Mac computer user, we still recommend keeping informed about how to keep safe while online. There is no such thing as a 100% safe computer. Mac, Windows, and even Linux computers are all capable of being infected with a virus or other malware.
