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.
1.Remove malware from Mac manually:
The Activity Monitor
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.
- Open Activity Monitor (type its name in the Launchpad).
- Locate the problematic app in the Processes.
- 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.
Tip
Do a quick search for virus-infected .DMG files within your Downloads. The potential culprits could be recently downloaded files, especially media-related ones. Delete them and empty the Trash bin.

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.

- Amazon Shopping Assistant by Spigot Inc.
- Slick Savings by Spigot Inc.
- FlashMall
- Cinema-Plus
This is just to give you an idea of how different these adware extensions could be. But if you’re looking at how to remove malware from the Mac Safari browser, follow this path.

6. 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.
7.How to remove daemons and agents from Mac startup
- Click Finder.
- Choose Go > Go to Folder.
- 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.
- Download CleanMyMac X (it’s free to download).

If all else fails
Below a few more ideas to help you remove malware from Mac.
- Switch to a different user account and do a full system cleanup.
- Restore your Mac using Time Machine (to the point before it got infected).
- Update all your software, including the macOS.
How to protect Mac from malware

These might also interest you:
A decade-old Windows malware trojan wormed its way into the macOS ecosystem, complete with a signed (likely stolen) Apple developer certificate. The exploit appears as an Adobe Flash Player installer. Once permission is granted, it hides itself deep inside macOS folders. Its certificate has already been revoked by Apple, but it's good to be aware of your enemies.
According to Fox-IT, Snake, a malware framework that has been infecting Windows software since 2008, and more recently Linux, is now targeting Mac.
Now, Fox-IT has identified a version of Snake targeting Mac OS X.As this version contains debug functionalities and was signed on February 21st, 2017 it is likely that the OS X version of Snake is not yet operational.Fox-IT expects that the attackers using Snake will soon use the Mac OS X variant on targets.
Snakes are dangerous and here's why
![Malware in library mac Malware in library mac](/uploads/1/2/5/6/125697302/714176053.jpg)
Similar to the Dok trojan that we heard about earlier this week, Snake popped up with an authenticated developer certificate, which means the Mac's built-in security system, Gatekeeper, would consider it legit and allow the installation process to complete.
It's important to note that Apple has already revoked this fake or stolen developer certificate, so Gatekeeper will block it. However, there is still a slight chance of someone downloading Snake by accident if they've found it through dubious channels. Malwarebytes explains:
Fortunately, Apple revoked the certificate very quickly, so this particular installer is no further danger unless the user is tricked into downloading it via a method that doesn't mark it with a quarantine flag (such as via most torrent apps).
How Snake slithers into your Mac
Just like most malware attacks, Snake doesn't just magically appear on your Mac one day. There isn't someone shooting corrupted files through your ethernet cable directly into your software. Snake has to be welcomed into your operating system by you.
Think of it is a vampire. If you don't invite it into your home, it can't attack you.
The file, named Install Adobe Flash Player.app.zip, will appear to be an Adobe Flash installer (Say what you will about Flash, but there are still a lot of people that have to use it for school or work). From Malwarebytes:
If the app is opened, it will immediately ask for an admin user password, which is typical behavior for a real Flash installer. If such a password is provided, the behavior continues to be consistent with the real thing.
Interestingly, once the installation is complete, Flash is actually installed on the Mac, making it even more difficult to tell that it's a trojan.
How you can protect yourself against Snake
As noted above, the fake/stolen developer certificate that allowed Snake to get a pass from Gatekeeper has already been revoked, so it's likely that, even if you download the zip file and try to open the app, your built-in security program will say, 'Nope Dope!'
But to refresh best practices, if you receive an email with an attachment at all, do some due diligence to make sure it's from a legitimate source. Check the sender address to make sure it is from an address you recognize. Click on the sender's name to view the email address it was sent from to make sure it's not a spoofed email. If you're still unsure, confirm with the sender by texting, calling or sending a separate email asking if the attachment is legit.
Specific to the Snake trojan, avoid downloading any zip files with the name Install Adobe Flash Player.app.zip.
What to do if Snake already bit you
Do you like my snake puns?
If you think you might have managed to accidentally install the Snake trojan onto your Mac, you can find and delete the following files:
- /Library/LaunchDaemons/com.adobe.update.plist
- /Library/Scripts/installd.sh
- /Library/Scripts/queue
- /var/tmp/.ur-*
- /tmp/.gdm-socket
- /tmp/.gdm-selinux
Next, delete the stolen/fake signed Apple Developer certificate.
- Launch Finder.
- Select Applications.
- Open your Utilities folder.
- Double-click on Keychain Access.
- Select the certificate named Adobe Flash Player installer with the signed certificate issued to Addy Symonds.
- Right or Control + click on the Certificate.
- Select Delete Certificate from the drop down options.
- Select Delete to confirm that you want to delete the certificate.
Lastly, change your administrator password to ensure that you're backdoor is rekeyed so the hackers can't get back in.
Remember best practices for staying safe
It is unlikely, at this point, that Snake will slither through your Mac's backdoor. For one, Apple has revoked the certificate, which makes it nearly impossible to make it through the installation process without you knowing about it.
How To Remove Malware From Mac
To reiterate, don't open attachments from unknown sources. Double check the sender email address to make sure it is not spoofed. Don't open suspicious-looking files or give administrator permission to unknown programs. You can protect yourself from attacks if you stay safe.
If you do end up with malware on your Mac, take a moment to relax and know that everything will be O.K. You can remove malware on your own, but if it seems too difficult for you to tackle, you can talk to Apple support. Someone will be able to help you.
