According to Malwarebytes, 2017 saw a 230% spike in malware activity within Mac ecosystem. The notable examples include Proton Remote Access Trojan and KeRanger virus. But whatever is that ends with “-ware” on your Mac — ransomware, adware, malware, or scareware — we’ll share a couple of methods to delete it. So, welcome to our Mac Malware Removal Guide.

Mac malware: The symptoms

Oftentimes a malware app would trick you into believing it’s perfectly harmless. Such apps are known to disguise themselves as antiviruses, extractors or video players. But how to check your Mac for viruses? Here are some of the tell-tale signs:

• A sudden drop in Mac’s performance or frequent freeze-ups.
• Pages that you visit get obscured with ads.
• Unexpected Mac reboots or apps starting for no reason.
• Your browser installs suspicious updates automatically.

How to remove a virus from Mac

Just as with any disease, to doctor a virus you need to remove the infected part of your software — as simple as that.

Remove malware from Mac manually

If you know which app on your Mac is malicious, you’re half-way through the problem. First of all, you need to close the app and then root it out from the system processes.

1. Open Activity Monitor (type its name in the Launchpad).
2. Locate the problematic app in the Processes.
3. Use [x] button to quit the process

Now go back to your Applications and move the app to the Trash bin. Immediately empty the Trash.

This method is simple, but for the best malware removal results, you’d have to invest a bit more time. There are still parts and pieces of the virus app scattered around your system folders. It’s a bit like killing a dragon that re-grows its head after you’ve chopped it off. To remove malware from your Mac completely, it’s better to use a powerful uninstaller.

Get rid of malware using CleanMyMac X

CleanMyMac X has a 10-year reputation of guarding Macs around the world. The app will scan your Mac for any vulnerabilities and offer immediate removal if it finds something suspicious. CleanMyMac detects thousands of malware threats, including viruses, adware, spyware, ransomware, cryptocurrency miners, and more. The app’s database is regularly updated to keep all those “-wares” away from your Mac.

Here’s how to remove malware from your Mac:

1. Download CleanMyMac X — it’s free to download.
2. Click Malware Removal tab.
3. Click Scan.
4. Click Remove.
5. Done!

How to remove Mac Adware cleaner

Ironically, the app called “Mac Adware cleaner” maybe itself be the very source of annoying adware on your Mac — the classic case of a wolf in a sheep’s skin. To remove it, you can use CleanMyMac (which is a legit app that has a 4.5-star rating from MacWorld magazine). Additionally, you can browse through your Login Items list to stop any dubious apps from auto-launching. Below is how to do it.

Remove Mac malware from your Login Items

Most adware or spyware will try to sneak inside the bootup process. Good news, you don’t have to be Kaspersky to prevent this.

1. Go to the Apple menu > System Preferences
2. Choose Users & Groups section
3. Make sure if your username is highlighted
4. Open Login Items tab

Now use the “—” sign to disable all the suspicious apps (like Mac Defenders) that you’ll find. Restart your Mac for the changes to take place.

How to get rid of pop-up ads on Mac

Advertising pop-ups are browser-related, so whatever browser you are using, be prepared for a thorough cleanup. First off, don’t buy into whatever the ad is telling you. Some scary alerts would mention 343 viruses found on your Mac forcing you to immediately install a “Mac Defender” or “Mac Security” tool. Just ignore it and don’t click anywhere on the pop-up. Use [x] button and if it doesn’t close the ad, Ctrl + click the browser icon to quit the browser completely.

How to block pop-up ads in Safari

1. Open Safari preferences (in the top menu)
2. Go to the Security tab
3. Tick “Block pop-up windows”

How to get rid of pop-ups in Chrome

How To Check For Mac Virus Terminal

1. Open Chrome Settings (a three-dot icon)
2. Click Advanced
3. Go to Privacy and security > Content setting
4. Locate the Popups tab and block them from appearing

Additionally, make sure your browser’s homepage is set to standard Google page or other trusted source.

Clean up extensions to remove adware from Mac

Apple lists several browser extensions as potentially malicious. The list includes:

Amazon Shopping Assistant by Spigot Inc.
Slick Savings by Spigot Inc.
FlashMall
Cinema-Plus

This is just to give you an idea how different these adware extensions could be. But if you’re looking how to remove malware from Mac Safari browser, follow this path.

Remove extensions in Safari

1. Go to Safari Preferences
2. Choose the Extensions tab
3. Select an extension and click Uninstall

Disable browser extensions in Chrome

And here’s how to remove malware from Mac Chrome. Open Chrome and click Window in the top menu. In the bottom of the list choose Extensions. This opens up the list of all your installed extensions. Now use a trash bin icon to remove the ones you suspect are adware viruses. Right after that, your Chrome experience should get much less distracting.

Just to be doubly sure, we recommend you to remove all the extensions you'll find. Later you can re-install each one separately.

Launch Agents and Daemons: Where else to look

So far we’ve covered browser Extensions, Applications, and Login Items trying to remove malware from your Mac. But these are not the only locations where malicious agents may be hiding. Another type of system services that could be affected by malware are the so-called Launch Agents and Daemons — yes, the name does derive from the word demon. These are small helper programs that stealthily run in the background, like software updaters or automatic backups.

While Launch Agents and Daemons are two different entities, both can be infiltrated by malware. As it often happens, trojan apps would place their executable files within the Launch Agents folder. The result — the virus app launches automatically and potentially harms or steals your data.

How to remove daemons and agents from the Mac’s startup

1. Click Finder
2. Choose Go > Go to Folder
3. Type in: /Library/LaunchDaemons

For Launch Agents, repeat the steps above, but this time search in 2 more locations:

/Library/LaunchAgents
~/Library/LaunchAgents

Inside you’ll find a bunch of PLIST files and if some of them look suspicious to you, delete them. Sure, the names of these files may not be very telling, but if you already know the problematic app that you are after, knowing this folder may help you fully extinguish it.

Don’t forget to reboot your Mac — until you do, all these files are still in memory.

One more way to remove daemons, agents, and plug-ins

If the manual path described here sounds too complicated, you can again be rescued by CleanMyMac X. This app has a special tool to remove malware Launch Agents.

1. Download CleanMyMac X (it’s free to download).
2. Install the app.
3. Click Optimization tab > Launch Agents
4. Click Perform.

By the way this app has a real-time anti-malware monitor. It monitors for any problematic apps that try to get into your Launch Agents. If it finds such, it will notify you and offer to remove the intruder.

According to the ClamXav home page –

Today, the number of viruses actively attacking OS X users is…NONE! However, this doesn’t mean we should get complacent about checking incoming email attachments or web downloads, for two reasons. Firstly, there’s no guarantee that we Mac users will continue to enjoy the status quo, but more importantly, the majority of the computing world use machines running MS Windows, for which an enormous quantity of viruses exist, so we must be vigilant in checking the files we pass on to our friends and colleagues.

So – do you even need anti-virus software on your Mac? That’s up to you to decide. If you do decide you want anti-virus software on your Mac, this tutorial will guide you through installing and using ClamXav – a free (and frequently updated) virus scanner for OS X.

Apple

1. Start out by downloading ClamXav. Once the download has completed, open the DMG file, and drag ClamXav to your Applications folder.
2. ClamXav isn’t very large, so it won’t take long to copy/install.
3. Open up an instance of Finder. Select your user name from the left navigation window, and go to Library ->Contextual Menu Items. Back in the opened DMG window, drag ScanWithClamXav.plugin to the Contextual Menu Items folder. Sign out of your Mac (or restart, but signing out and back in will do the trick). Signing out and back in again will activate the “Scan with ClamXav” plugin.
4. Now launch ClamXav from your Applications folder. You’ll be prompted to install the Clam Anti-Virus engine. Click the Install button.
5. On the Introduction screen, click Continue.
6. Review the Software License Agreement and once again, click Continue.
7. Click Agree to accept it, again.
8. Now click Install.
9. Enter your password when prompted, and click OK.
10. And now the scanning engine will install.
11. Click Close once the process has completed.
12. Now launch ClamXav from your Applications, again. Before you start the scan, click the Update virus definitions button.
13. Once completed, you should see a Virus definitions updated successfully status message.
14. Now click the Preferences button.
15. On the General tab, make the selections that are appropriate for you. I opted to quarantine infected files rather than outright delete them, in case of any false positives (ClamXav flagging a file as being infected with a virus, when it in fact isn’t).
16. Depending on which settings you opt for, you may receive a message telling you not to turn on certain features if you plan on having your email scanned or watched. This wasn’t an issue for me as I use Gmail (via the web) but it is something to consider if you use Mail or Entourage for email.
17. Select the Internet tab, and again, make any changes you see fit. I opted to have ClamXav check for all possible updates each time it starts.
18. Select the Schedule tab, and if you’d like to schedule virus scans, this is the place to create them.
19. Select the Folder Sentry tab. From here you can add folders to be constantly monitored for viruses (eg. your Downloads folder). Review the other options and make any changes you see fit. Click OK when you’re done.
20. Back in the main ClamXav window, click the Choose what to scan… button.
21. If you attempt to select your entire startup disk (as indicated in the screenshot below)…
22. you’ll get an error.
23. So instead, just select all of the folders (hold down the Apple Key to select multiple items) on the drive you want to scan. Then click Open.
24. Finally, click the Start Scan button.
25. ClamXav will do a “quick” (it’s not that fast) scan of your drive to determine how many files it’s going to check.
26. And then they actual scan will begin.
27. At this point, you might as well settle in for the long haul. Depending on the size of your hard drive, the number of files on it, and the speed of your Mac, the process can take quite a long time. As indicated in the screenshot below, it took ClamXav 172 min and 31 seconds to complete on my MacBook Pro (an older one). With all of that said, I was able to work on my Mac the entire time without much of a noticeable slowdown. However, I kept my tasks to the relatively ‘safe’ – the last thing I wanted was a crash in the middle of the scan, forcing me to start over again. Running the scan overnight while you’re sleeping is probably a good idea.
28. And that’s it. Now you may want to scan your Mac for spyware, malware and tracking cookies.
