How to Remove Malware from Your Mac

Before we start

 

Do you really think Macs are immune to malware?

 

Here's a tip: Download Clario and remove spyware from your Apple devices.

 

Has your Mac started crashing, acting strangely, making random sounds, or just seeming a little sluggish of late?

 

How about annoying pop-ups and unexplained browser redirects - have they suddenly started making an unwelcome appearance?

 

It can be tricky to pinpoint exactly what’s ailing your beloved MacBook or iMac when these issues start appearing.

 

The good news is, more often than not, it's just a glitch. Maybe a minor hardware issue, or your macOS has a bug that needs resolving. In short, nothing too nefarious to see here.

 

But, it could also signal some seriously unwelcome news: A malicious piece of software has infiltrated your beloved MacBook or iMac.

 

If this is the case, though, we can promise you that all is not lost. There are ways to root out that pesky malware before it can cause some real, costly damage.

 

In fact, if your Mac’s performance does tip you off to a potential malware infection, then you should consider yourself one of the lucky ones. Many cybercriminals have created some seriously sophisticated malware programs that operate quietly in the background and don’t make your Mac act suspiciously at all.

 

Meaning you’re none the wiser, while they’re lurking behind the scenes, potentially stealing your passwords, credit card info, and more for their own gain. Ouch.

 

But don’t worry. We’ll walk you through all the options, then you can decide for yourself how to remove the malware once and for all. Thankfully, there are lots of ways to go about clearing malware and viruses from your Mac that won’t cost you an arm and a leg.

 

For now, though, let’s debunk the biggest, most enduring Mac myths of all - that they're immune from malware.

Yes, Macs can get infected with malware

We've covered this in a lot more detail in an earlier article. But despite Apple’s best efforts and the fact that cybercriminals generally prefer to target PCs, yes, your Mac can absolutely contract a malware infection.

 

Notwithstanding the fact that Macs come with a built-in security software (called XProtect) that works to detect and remove malicious software, malware that can get around your Mac’s built-in antivirus is indeed a thing, and it’s on the rise.

More recently, in fact, there’s been quite the uptick in adware and Potentially Unwanted Programs (PUPs) outbreaks directed specifically at Mac users. To put this alarming trend into context, SecureList found that 1.8 million Mac malware attacks took place in the first half of 2019 alone. There have even been known instances of Mac ransomware in recent years.

 

Clario’s step-by-step guide to cleaning malware from your Mac

Some Mac malware removal methods work better than others, depending on the extent of the infection and the severity of the malware. Here are two approaches to cleaning up your Mac.

 

Option 1: Download a (legit) anti-malware program designed specifically for Mac

 

This is by far the quickest, most painless solution to your Mac malware woes.

 

In just a few clicks, a Mac anti-malware program, like Clario, can clear out any nefarious malware apps on your Mac.

 

Best of all, you can try it out today!

 

Option 2: Manually remove malicious applications from your Mac

 

If you’ve sussed out exactly what program on your Mac is malicious (some notable offenders include Bird Mine, OSX/Linker, OSX/CrescentCore and CookieMiner, although many other types of Mac malware are floating around) and want to handle removing it yourself, then you can follow these easy step-by-step instructions:

Step 1: Disconnect your Mac from the internet

Consider this a damage-control measure. It’s far and away the best way of curbing the malware spread and preventing more of your data being accessed by cybercriminals.

 

If you do decide you need a Mac malware removal tool, you can quickly reconnect to the internet for the duration needed to access one, then immediately disconnect once your download is complete.  

Step 2: Enter Safe Mode

Boot your Mac into Safe Mode. All you need to do here is hold the Shift key when the Apple logo makes an appearance.

 

This way, you’re starting your Mac with only the most essential programs needed for it to load, stopping any potential viruses from running amok. 

Step 3: Close the suspicious app (if it’s still running)

On your Mac dock, click Finder (the one that looks like a happy face) > Utilities > Activity Monitor. 

Step 4: Click on Applications

This will display any processes running on your Mac, including malicious software.

Step 5: Find and uninstall the suspicious app

You’ll be able to force the app to close within the Activity Monitor, then manually delete it via the Finder. Finally, don’t forget to empty the Trash (no dawdling at this point, you’re almost there!)

Step 6: Don’t forget to clear malware extensions from your browser

Adware especially loves to attach itself to your browser (and drive you stir crazy with unrelenting pop-ups), so this is a step in the malware clean-up process you don’t want to miss.

 

Removing malware from Safari: Go to the main menu and click on Safari Extensions. Locate the offending piece of adware. Click Uninstall. Remember to clear your cache when you’re done. 

Step 7: Don’t forget to check your Login items

Hey, don’t say we didn’t warn you that malware creators are a sneaky sort.

 

So sneaky, in fact, that they’ll often try to find their way into your Mac’s startup process so they can really take over the show.

 

Here’s exactly how to circumvent them:

  • Go to System Preferences.
  • Select Users & Groups.
  • Check your user name is highlighted.
  • Open Login Items
  • Use the "—" to disable any malware running.
  • Restart your Mac.

I think my Mac may still be infected with malware. What do I do?

Yep, we hear you - even with all these steps, malware removal can be a tricky beast.

 

It’s a bit like playing whack-a-mole trying to keep the fraudsters at bay. There might be parts of the malware app hiding out or otherwise lying dormant within your macOS, biding its time until it rears its ugly head and infiltrates your system once again.

 

And more often than not, you’ll be none the wiser as to what malware exactly you’re infected with, how it got into your computer in the first place and where it’s setting up shop in your computer’s system.

 

That’s why we heartily recommend installing a reputable antivirus app that can scan your Mac and catch any lingering vulnerabilities.

How to avoid getting another malware on your Mac

If you already have antivirus software running on your Mac, then you might want to consider scrapping it, then looking for another provider.

 

After all, your current antivirus program let that piece of malware slip through - who’s to say it won’t happen again? As the old saying goes, once bitten, twice shy.

 

And don’t rush into buying just any Mac anit-malware. The internet is chock full of bogus antivirus software that’s really just another piece of malware in disguise.

 

Your best bet is to shop around, do your research and opt for one that’s been highly rated by reputable tech review sites, like Techradar or MacWorld.

If all else fails, will factory reset remove the malware from my Mac?

Yes it can, but consider this more of a last resort, if you've followed all the steps above to no avail. The downside here, of course, is that you’ll probably lose any important files and docs you were working on since the malware wormed its way in. That said, if you’re someone who backs up everything to iCloud, Dropbox or another external backup solution, it shouldn’t be too much of an issue for you to recover this data if your Mac does get infected by malware.

 

All you have to do is restore your Mac using Time Machine (Apple’s inbuilt backup system), which lets you quickly restore your Mac to a happy working state (i.e. a point in time you know for sure your machine wasn’t infected). This way, you can do a wholescale update of all your software and macOS and know for sure your Mac has been cleaned of anything sketchy.

 

Time to breathe a sigh of relief - you have your malware-free Mac back again! Before you go, though, we’ve got a little piece of homework for you: read up on how to avoid getting scammed or phished again. After all, we don’t want you to find yourself having to remove another malware from your Mac again.
