Sep 26, 2019  Let’s be clear: antivirus software for your Mac is not essential. If you follow the basic “common sense” practices covered above, the chances of infection remain low. Even with an antivirus, your system could fall victim to a new, undocumented infection. Aug 22, 2019  Bitdefender Antivirus for Mac Protection against Mac and Windows malware Bitdefender runs in the background, deleting and eliminating Mac and Windows malware as it shows up. This protects both your Mac and friends' PCs from becoming infected. Nov 11, 2018  Any Windows user that operates without antivirus software is responsible for any infection they encounter. It's not up to a Mac user to provide malware protection for Windows users, and do do so would still leave such users vulnerable to all the Windows malware on the network that doesn't come through your Mac.

You should strongly consider protecting your Mac with a top-rated antivirus
program such as Bitdefender Antivirus for Mac ($39.99 for one year).

In the old days, things were simple for Mac owners. Computers running OS X didn’t get viruses or malware. It was far more lucrative for hackers to target PCs instead because there were so many more of them out there.

Today, a Mac that runs the OS X operating system is still far more secure than a PC running Windows. But that’s not to say Macs aren’t at risk. Apple dropped its “Macs don’t get viruses” advertising line two years ago following a high-profile botnet attack that infected over half a million computers. And, plenty of new malware threats have arisen in the meantime. Given the recent growth in OS X market share, the threats will keep coming.

Apple computers running OS X do have a default security program called XProtect built in. Unfortunately, testing has shown that protection to be quite unreliable. Thomas Reed over at Safe Mac ran a test of XProtect and found it failed to protect against many known malware programs – even older, well-known threats. If you don’t have a third-party security program running on your Mac, you’re definitely at risk for an attack.

Other threats to Mac owners

There are plenty of threats to your Mac beyond malware, too. Last week, Techlicious reported on a new computer bug affecting some Macs called Shellshock (Bash). If exploited, a hacker could execute a wide range of commands on your computer, effectively taking it over. Apple has since released a patch for OS X, which you can download directly from its website. Security researcher Greg Wiseman of Rapid7 warns, however, that the coverage that patch provides may be incomplete.

Another danger for Mac owners: Phishing attempts are on the rise. Thieves are getting increasingly clever with spoofing emails and websites, tricking even some of the most alert web users. Some crooks are using holes in Javascript to place their own webforms on your bank’s homepage. Many Mac security products will protect against these types of identity-theft attacks.

The best internet security software for Macs

Earlier this year, the security researchers at AV-TEST put 18 different OS X security software offerings to the test, seeing how each performed against known threats. Here, BitDefender, GData, Norman and Microworld all come in with perfect scores, identifying 100% of the malware infections it was tested against. Avira (68.4%), Symantec (54.7%), Trend Micro (38.5%), McAfee (26.5%) and Webroot (19.7%) all scored the lowest detection rates of the bunch.

Bottom line: If you own an Apple Mac, you should definitely invest in solid Internet security protection. Personally, I like the simple-but-effective Bitdefender Antivirus for Mac 2015. It tests well across the full range of malware threats, protects against malicious links, scans quickly and seems light on my computer’s resources. You can purchase a one-year subscription to the anti-virus platform for $39.95 (or $59.95 for up to 3 Macs) through bitdefender.com.

Best answer: Though Windows malware doesn't affect Mac devices, it's easy to unknowingly send these threats to PC-using colleagues, family members, and friends. During our testing, we used live malware and saw that the protections that come with Mac devices don't always stop them. Several threats are disguised to look like legitimate Mac programs and often sneak in through email messages and network connections. Luckily, a good antivirus program can stop them while keeping your Mac safe.

Do Macbooks Need Virus Protection

If you start to notice weird advertisements popping up in strange places on popular websites like YouTube, you might be infected. These ads tend to feature adult content or claim that a virus has been detected on your device and will often appear in places that you don't normally see ads.

You may also discover that your personal email or social networking sites are sending out messages that you didn't write. If this happens, you should immediately change your password to stop any more messages being sent from your account.

If your Mac just isn't responding the way it should, you might have malware planted into your system somewhere. If it takes much longer for your Mac to wake up than it used to, there may be something lurking in the shadows.

You won't always know if you have a virus. Technology has improved for the bad guys just as much as it has improved for the good guys. There are viruses out there that are smart enough to know how to hide deep in your system and work constantly to keep you from noticing it, all while performing malicious attacks. And once you're infected, it super easy for other devices connected to your network to become infected, too.

While you may think you don't need antivirus protection on your Mac, it's more important than ever now that Apple has grown so popular. Even if you use a limited, free version of a program, you'll be doing yourself a favor.

Do You Need Antivirus Software For Mac

How can I protect my Mac right now?

The Mac operating system includes a number of security tools that help keep adware and malware off your computer, including default restrictions on opening apps from unidentified developers. If you stick to only downloading apps from the Mac App Store and are good about staying away from seedy websites, you can keep your computer secure from most virus issues.

In fact, Apple's security tools are why you'll hear many old-school Mac users say that you don't need anti-virus protection. The Mac is locked down well right out of the box.

However, there is more to protecting yourself than just avoiding bad apps and websites. You never know when you are going to pick something up that could create havoc on your Mac or on somebody else's PC. That's why, for added protection, you should think about getting antivirus software.
