Understanding Mac Malware
Now, even with XProtect built into macOS and third-party anti-malware software, your Mac can still get infected.
I explain why in episode 98, so if you missed it, I recommend checking it out.
In the previous episode, episode 99, I guided Macpreneurs like you through a Mac security checklist aimed at raising the bar to prevent your Mac from being compromised.
However, malware is becoming more and more sophisticated, and it's essential to know the warning signs of infections before it's too late.
My goal with today's episode is to arm you with the necessary knowledge by sharing 7 signs that your Mac might be infected with malware.
Knowing these can help you act quickly to protect your data and your business.
Sign 1: Browser Issues
Ok, sign number 1: browser issues. Malware can alter your browser settings, such as changing your homepage or redirecting you to unfamiliar websites.
One of my clients got bitten by that in Google Chrome, and the problem, luckily, was only happening for a main profile. So, in her case, the solution was simply to wipe the Google Chrome profile that she was using and then create a new one.
Now, frequent browser crashes can also be a symptom, and the first line of defense to prevent that from happening is to make sure that your browser is fully up to date and also to install a content blocker.
Sign 2: Unexpected Pop-ups
Sign number two: unexpected pop-ups and advertisements.
If you start seeing an unusual number of pop-up ads, even when you're not browsing the internet, this could indicate adware or other malware.
And if you see a ransom note asking you to pay a certain amount of bitcoins or other cryptocurrency to get your data back, first double-check whether it's true or not.
For that, visit the Documents folder and all the folders that you synchronize with your cloud backup services of choice, such as iCloud Drive, Dropbox, OneDrive, Google Drive, and so on.
Try to open any of your business-critical documents and see if they are indeed unreadable.
Next up, check your Time Machine backup disk, which may or may not have been affected too.
If you can restore data from the Time Machine Backup, then you're lucky.
Otherwise, your only other solution would be to restore from an offsite or a cloud backup.

If you haven't put in place an offsite backup strategy yet, I recommend signing up for Backblaze, an extremely affordable cloud backup solution. You can get unlimited storage for a mere $99 per year. Just for that, I'm storing more than 4TB worth of stuff.
It's possible to encrypt all the files with a password, preventing anyone, including Backblaze, from accessing the backed-up data. It's also possible to enable a one-year version history, totally for free.
You can choose the region where the cloud servers are located, and for folks in Europe, it's in the Netherlands. The backed-up data is accessible from my iPhone and my iPad via their mobile app.
And so you can try Backblaze for free for 15 days via my affiliate link macpreneur.com/backblaze.
No credit card required. And if you end up becoming a Backblaze customer after using my affiliate link, I will get a small commission at no cost to you.

Sign 3: Unfamiliar Applications
Sign number three: unfamiliar applications.
If you notice new applications that you didn't install, it's possible that malware has added them to your system.
In this case, simply putting those applications in the trash is usually not enough, since the malware at the root of it tends to hide itself deep into the system and respawn after each subsequent reboot.
Sign 4: Strange System Behavior
To deal with that, it's the same as the next sign, sign number four: strange system behavior.
Your Mac might open applications or files without your initiation, and you may notice high CPU usage and the fan running excessively.
These can also be signs that a malware infection is working in the background.
The first thing to do is to launch Activity Monitor, which is available inside a folder called Utilities, inside the Applications folder.
You will see different tabs in Activity Monitor, the first one being for the CPU usage. Sort by the column named '% CPU' to check which processes consume the most, and then you could Google the names of the top ones if you don't recognize them.
The second tab is memory, and there's the same thing. Look at what consumes the most, and then go through all the others.
Even though it's possible to kill a rogue process, it's highly likely that it will relaunch itself automatically, either almost immediately or after the next reboot.
And so, the second thing to do, and to double-check, is what gets launched at login.
If your Mac is running macOS 13 Ventura or later, open System Settings, then General, then Login Items.
And on macOS 12 Monterey or earlier, open System Preferences, visit 'Users and groups', then 'Login items'.
If you don't see anything out of the ordinary there, the malware could be hidden further, which is a bit too technical to get into for this podcast.
More often than not, malware scanners will check those hidden folders for you.
Sophos Anti-malware Affiliate Promo
And so, if you're still looking for a low-cost malware protection tool and remover for your Mac, I wholeheartedly recommend you consider Sophos.
With a paid plan, you can protect up to 10 computers, Macs or PCs, and everything is configured through an intuitive web portal.
And if you have kids, you can also easily configure some web browsing rules that they won't be able to circumvent.
You can try Sophos for free for 30 days using my affiliate link, macpreneur.com/sophos, S O P H O S.
Download and install Sophos, then create an account. No credit card required.
And if you end up becoming a Sophos customer after using my affiliate link, I will get a small commission at no cost to you.

Sign 5: Slow Performance
Sign number five: slow performance.
The Mac might become noticeably slower, with apps taking longer to load and the system generally lagging.
You will also often notice this kind of beach ball icon in place of your cursor.
This can be due to malware consuming resources in the background.
To address this issue, follow the same procedure as mentioned before. First, open Activity Monitor, and then check the Login Item.
Sign 6: Unusual Network Activity
Sign number six: unusual network activity.
If your internet connection seems slower than usual and you notice data being transmitted when you're not using the internet, this might be due to malware communicating with its command servers.
To check for this, open Activity Monitor again and navigate to the last tab called Network
Sign 7: Unexpected Webcam or Microphone Activity
Sign number 7, the last one: Unexpected webcam or microphone activity.
If you notice that your webcam light is turning on and off without your initiation, or if you hear your microphone activating randomly, it could indicate that a malicious application is accessing these devices.
Since macOS 12 Monterey, you will see an orange dot in the top right corner of the menu bar next to the icon for Control Center whenever an app accesses the microphone.
Just click on the Control Center icon, and it will show you the name of the app in question.
To double-check all the apps that have access to your camera and microphone, or on macOS 13 Ventura or later, open System Settings, then 'Privacy & Security', then open the Microphone and Camera sections.
On macOS 12 Monterey or earlier, open System Preferences, then Security & Privacy, then, on the Privacy tab, open the Microphone and Camera section.
Conclusion and Recap
So before concluding this episode, there's one more thing I'd like to mention. Most attacks are opportunistic, which means that everyone is at risk, and it usually takes one small mistake or misjudgment on your part to fall victim.
Never let your guard down and remember, the more pressured you will be to do something, the more likely it is a trap.
So to recap, we've gone through 7 alarming signs that your Mac might be infected with malware: browser issues, unexpected pop-ups, unfamiliar applications, strange system behavior, slow performance, unusual network activity, and finally, unexpected webcam or microphone activity.
Recognizing these signs early can save you a lot of trouble and keep your solo business secure.
On top of that, it's possible to minimize the risk of your Mac getting compromised.
How? By going through the checklist that I've covered in episode 99.
