In the past, I contacted Apple multiple times. One thing I learned is that when their tech support suspects a possibility of a virus on your Mac, they usually suggest downloading and running free Malwarebytes.
While I have never found any malware on those occasions, I do know how Malwarebytes works and can help you decide whether you need it or not and whether it is worth paying for.
In this article, I would only cover Malwarebytes for Mac. There is also a Windows version, but I have no opinion about it.
The story of Malwarebytes for Mac started when it was called AdwareMedic. The product was a donationware developed by Thomas Reed. In 2015 Malwarebytes, a software company from California acquired AdwareMedic and rebranded it as Malwarebytes Anti-Malware for Mac. The best thing is it still has a free version.
Is malwarebytes good for mac?
Yes, Malwarebytes is a well-regarded anti-malware solution that effectively protects Macs from various threats. It is a good choice for users looking to safeguard their Macs.
The company displays reviews on its main site. At the moment of writing, there were 123 reviews with an average rating of 4.8. Since most people usually leave reviews when they extremely happy or extremely unhappy with the product, the rating is impressive.
Most positive reviews mentioned the cases when the product was able to catch a virus or malware. There are a few negative reviews, and they mention problems with contacting the support.
And the majority of reviews mention that they were recommended by Apple tech.
Malwarebytes Free vs. Premium
If you go to the Download page, you can see a table comparing Malwarebytes Free and Premium editions. Scanning for threats and removing malware is the same in both versions.
In addition, the Premium version comes with real-time verification. And this part is crucial.
If the free version scans and detects viruses after they get on your Mac, the Premium version stops the malware before the Mac gets injected.
So, every time you open a mail attachment or browse a site, the Premium version of Malwarebytes verifies that they are free from malware. The free version doesn’t do it.
It means that when you browse a compromised web site, the free software will let you download malware, install it, and run. Imagine, you somehow got Keranger, MacRansom, or another ransomware app.
How long do you think it will take until it encrypts the entire disk? If you didn’t run scans while the malware was running quietly on the background, you might end up with a totally dead computer.
Malwarebytes allows running scheduled scans, but the feature is only available in Premium edition.
Malwarebytes has an API that can be called programmatically, and I have to admit, I tried to devise a plan to force the free version to run on a schedule I could set up with a third-party app. Unfortunately, the ability to run scans is only available with Premium, so no luck.
Is Malwarebytes Free Good Enough
To find how good is free Malwarebytes, I ran a test. The full video of the test is on YouTube:
I downloaded and installed Malwarebytes for Mac. After installation, I intentionally chose a free version (I could’ve choose a free 14-day Premium trial).
In my test, I had two keyloggers installed: Elite and Refog. Both are legitimate products, and they can be legally purchased online.
But since by nature they perform something that can be classified as potentially dangerous (if they were installed by someone who wants to steal your data), most antivirus products should detect them. Malwarebytes, even free ones, quickly detected them. So far, so good.
However, my Mac contained more than two keyloggers.
When I was working on testing antimalware solutions for Mac, I downloaded 117 malware samples to my Mac. They all resided in one folder on the startup disk.
However, the scan didn’t detect anything.
So, I browsed to my Virus folder and started AdWind. AdWind is a type of backdoor. It can download malicious software, execute remote commands, send data to the server controlled by a hacker, and record it through the webcam.
The only notification I got was from Apple, which stated that I shouldn’t download unverified software from the Internet. It’s a standard message you can get when downloading any executable. And in most cases, most users ignore the warning.
What about MalwareBytes? It didn’t warn me about anything.
But since I knew about the malware, I was able to find its traces: the folder it created under Users folder and a file in the LaunchAgents.
Then I ran another malware: Calisto.
Calisto disguises itself as an Intego antivirus installer. But this is not a real antivirus. It tricks you into entering an admin password (something we all do when installing antiviruses), but in fact, it created a new hidden folder called .calisto under Users folder.
So, what Calisto does: it’s another backdoor malware. It gives remote access to the hacker – it enables remote login, screen sharing, creates a hidden root account, etc.
Again, Malwarebytes said nothing.
The last malware I tried was Lamepyre. It pretends to be a Discord app, but it’s not. Instead, it takes screenshots and sends them to the server controlled by hackers.
Again, Malwarebytes didn’t warn about anything.
After that, I ran a manual scan, and finally, Malwarebytes detected all of them very quickly and offered to quarantine malware.
So, that’s the main difference between free and Premium versions: the free version does not support real-time protection.
The problem with this is that users may have a false sense of security after installing the program, when in fact, it does not protect your Mac unless you run manual scan pretty much every time after you do anything online or copy and file.
What I Like About Malwarebytes
I liked two things:
Malwarebytes is insanely fast. I tested a dozen of antivirus products, and I know what I am talking about: MalwareBytes scans faster than any other antivirus for Mac. On average, it takes no longer than 30 seconds for the Malwarebytes scan. However, there is a downside to faster speed, as indicated in things I don’t like section.
Virus and keylogger detection
Malwarebytes found all malware I was able to run on my Mac. And it was pretty good with keyloggers. The only keylogger it failed to detect was Perfect keylogger, but it is was hard to detect for all AVs (hence the name Perfect).
What I Don’t Like About Malwarebytes
No disk scan
Imagine you have a USB stick, and you want to check it for malware.
How do you do it normally when you have an antivirus? You plug it into your computer and point the AV to run a scan against the USB drive.
There is no such thing in Malwarebytes. Malwarebytes only detects malware when it is in memory; that’s why it scans so fast. Instead of scanning the entire disk and external drives, MalwareBytes quickly scans the processes in the memory, and that’s all.
If you try to open a file infected with a virus, then, depending on the version, the MalwareBytes will either do nothing (free) or scan it (Premium).
Lack of features
There three Premium features promoted on the compare screen: stopping exploit attacks, blocking ransomware attacks, and preventing access to and from known malicious websites. But if you look carefully, they are only available for Windows, not for Macs.
Why is this important?
Viruses and malware, in general, are just one way to harm your computer. Unfortunately, lately, the hacker community became larger and more active than before.
One way to attack a computer is to find a vulnerability in the OS, such as macOS, and use it to deploy a backdoor app. Once malware is installed, hackers can use it and run various exploits, such as track keystrokes, remote login, or screen sharing and then steal your information. Frankly, I would prefer to have protection from both malware and exploit attacks.
And now, I am ready to make a conclusion.
When Should You Use Free Malwarebytes?
If you notice certain changes in the MacBook behavior, such as sudden slowness, unusually high CPU, or Internet usage, and there is no other antivirus installed on Mac, then do what Apple tech support advises in this case: download free Malwarebytes and run the quick scan.
If there is a malware installed, the chances are that MB will find it.
Please check my review of other free Mac antiviruses.
When Should You Use Premium Malwarebytes?
If you need 24/7 malware protection, then the free version will not work for you. You have to upgrade to Premium. However, the absence of a disk scan makes MB a less desirable solution.
Instead, I suggest checking my post where I tested a dozen more antivirus products (in addition to Malwarebytes), and go with the one I recommend: Best Malware Detection App for Mac Removes 117 Viruses In 5 Min
