- Malware On My Mac
Macs don't get viruses, right? Wrong, sadly. Your Mac may be safer from malware than the average Windows PC, thanks to its Unix core and Apple's default security settings in the OS, but it's not immune. All it takes is one thoughtless click on a link in an email or on a website, and your Mac could be infected.
The good news is that performing a Mac virus scan is very easy and if it finds anything, getting rid of the virus is very straightforward, too.
It tries to brainwash the user that the MacBook Air is infected by a malware and that the user should immediately choose to 'Scan Now.' However, by doing so, it only leads the user to another harmful cargo. Adwares on MacBook Air. Another kind of threat to browsers installed on MacBook.
- To get rid of malware, you need to purchase the Premium version of Combo Cleaner. Open the app from your Launchpad and let it run the update of malware signature database to make.
- While it's true that Apple computers like your MacBook Pro are less susceptible to viruses, that doesn't mean that they won't ever get one. In fact, according to a recent report by Apple Insider, malware viruses specific to Macs, in particular, have grown 60% in 2019.
How to check your Mac for a virus
There are a number of tell-tale signs that your Mac has a virus. If it's not displaying any of those, there's probably nothing to worry about. So, before you scan your Mac for a virus, here are a few things to check.
1. Is your Mac behaving erratically?
This could include applications crashing, web browsers loading pages you didn't ask for, and unusually high traffic on your network.
2. Has it started running very slowly all of a sudden?
Some viruses run processes that hog CPU cycles and leave little capacity for the tasks you want to carry out.
3. Are you seeing adverts or pop-ups for things you would never normally see?
Adware viruses are designed specifically to show adverts in the hope that you'll click on them.
4. Have you noticed software appear on your Mac that you didn't deliberately install?
Some viruses appear in the form of browser extensions, others run in the background, but some may appear as applications in your Applications folder. Before we'll explain how to scan Mac for malware, check these 5 tell-tale signs.
If any of the above are true, it's possible that your Mac has a virus, but don't panic, it may be relatively easy to remove.
How to run a malware scanner on Mac
So how to check for malware on Mac? There are several Mac virus scanners that allow you to scan your system. However, it's very important that you don't just google ‘free Mac antivirus software.' Many sites that claim to offer free antivirus tools in fact host viruses themselves. So, you go to the site looking for a solution and end up making the problem worse. It's important to use a reputable tool. We recommend using CleanMyMac X.
CleanMyMac X detects thousands of malware threats, including adware, spyware, worms, ransomware, cryptocurrency miners, and if it finds something suspicious, it offers immediate removal. Here's how to scan your Mac for malware:
- Download CleanMyMac X (free edition here) and launch the app.
- Click on the Malware Removal tab.
- Click Scan.
- Click Remove.
Malware Monitor is another thing I love about CleanMyMac X. And this Mac malware scanner works in real-time. Whenever an adware attempts to enter some protected areas on your Mac, you'll get instantly notified.
How to get rid of suspicious apps
If you find an application that you didn't intend to install, you should get rid of it. But don't just drag it from your Applications folder to the Trash, that won't remove every trace of it from your Mac. Applications store files in a number of different places in your Mac's Library folders. You could hunt them down and remove them manually, but it's quicker and easier to use a dedicated uninstaller like CleanMyMac X. That way, you can be sure you will remove every trace of the application and no stray files will be left behind.
- Download CleanMyMac for free here.
- Launch it from your Applications folder.
- In the Utilities section, click on Uninstaller.
- Look through the list of applications until you see the one you want to get rid of.
- Check the box next to it.
- Press the Uninstall button.
How to prevent your Mac from getting a virus
Scanning Mac for malware is one thing. But prevention is always better than cure. So, if you want to make sure that every virus scan returns a clean bill of health, here's what to do.
- Never click a link in an email unless you're 100% sure where the email has come from and where the link will take you. Reputable companies and banks won't ask you to click a link to log into an account, for example.
- Never download anything unless you're certain what it is. That includes movie files, software updates, games, and anything else you're not absolutely certain about.
- Keep your Mac updated with the latest version of macOS. That doesn't mean you have to be running the very latest OS, but if you're running, say, Sierra, make sure you install the latest updates when they become available.
Scanning your Mac for threats is very easy. To check Mac for malware, you can download the free version of CleanMyMac X which is an Apple notarized app. With its help, you get rid of any applications you didn't intend to download and scan your whole system for malware very quick and easy. Give it a go.

I think my Mac has a virus!
If this is your first thought, then the next one is probably: how can I check for a virus on my Mac? Whatever your circumstances are, don't panic!
I also suggest you read the entire post without rushing to implement 'expert' recommendations. If you indeed have a virus, it happened due to a lack of knowledge, and the same lack of knowledge can make things worse. First, understand what the problem is and then try to fix it.
So, in short, here's what you should when malware is a suspect.
If you think that your Mac has a virus, the quickest way to verify it is by scanning the computer with the Malwarebytes for Mac program. Download a free version of Malwarebytes, and it will fully scan your Mac for malware in less than a minute.
Myth About Macs Being Free From Viruses
The myth that Macs are protected from viruses is just a myth. Heic to png converter software. While Macs are less targeted than Windows, they still have their share of malware.
For instance, KeRanger ransomware was detected in 2016 and it designed for macOS. It even affected several Macs in Apple headquarters in Cupertino, CA.
In 2019 there were several Mac-specific malware programs detected:
- OSX/Linker – exploited a zero-day vulnerability in macOS
- LoudMiner – uses your Mac to mine Bitcoins
- OSX/NewTab – adds new tabs in Safari with malicious web sites
- NetWire – spyware
So, if you thought you were shielded from viruses because Macs don't get viruses, you were wrong.
Did you know?
The first ever virus was written for the Apple II computer by Rich Skrenta when he was 15 years old. The virus did not do any harm to computers; it displayed a following poem on the screen:
Typical Signs That Your Mac Might Have Malware
There are several symptoms that may (or may not) indicate that the Mac was infected with the malware:
- Your Mac is slow or crashes unexpectedly
- The startup disk is running out of space
- Pop-ups appear on the screen when you are online or offline
- The browser home page or search engine has changed without your permission
The symptoms mentioned above can be caused by other things, however. For instance, you may be running Time Machine backups that taking entire disk space.
If the browser home page has changed after installing an app, sometimes all you need is to change it back.
But if you suspect something, it never hurts to scan the Mac for malware.
Will Your Mac Tell You If You Have A Virus?
The answer is as always: it depends.
macOS has two malware protection mechanisms: Gatekeeper and XProtect.
The way the Gatekeeper works is by setting the Quarantine Flag when the file gets downloaded. So, when a user opens an app with this flag, the Gatekeeper will check if the app came from a trusted developer or not. If not, then it will pop a warning message.
This message does not necessarily mean that the app is malware. It only means the macOS does not know anything about it. It is possible to override the warning by going to the Security and Privacy pane in the System Preferences app.
XProtect is another built-in protection system on macOS. It contains definitions of many malware programs.
When the Gatekeeper on Mac checks the file marked with the Quarantine flag, it also searches the file signature in a malware database provided by XProtect. If the signature is found, then your Mac will tell you that you have a virus.
For instance, in April 2019 the XProtect was updated to include TrojanSpy.MacOS.Winplye, a Windows file that can run on Macs.
So, if you happened to download an app that contains this Trojan, the XProtect would prevent it from running. However, there is a caveat. You must have the security update installed on your Mac.
So, here is rule number 1 for anyone who wants to make sure that their Mac is secure: Always have automatic updates turned on.
Here's What To Do If You Think Your Mac Has a Virus
Now, when we know, all the theory behind viruses and malware, let's do some practical things.
When I called the Apple support and told them that my MacBook is slow the first thing they suggested to restart the laptop in Recovery mode. The next step was to install the antivirus.
If you have reasons to believe there is a malware on the computer, skip the first and download the antimalware program.
The Apple support guy directed me to install Malwarebytes (affiliate). He and I enabled the screen share and here is exactly what he told me to do:
- Start Safari browser
- Type Malwarebytes in the bar and click on the link
- Click on the Free Download button
- Open Finder and go to the Downloads folder
- Double click on the Malwarebytes install file
- The installer program will start
- Keep clicking on Continue, Agree, and Install keys
- The app will require to enter the admin password
After installation, Malwarebytes will offer 14 days of Premium option for free. Click Not Now. You don't need it.

When Malwarebytes starts, click on Scan pane on the left and then click on Start Scan. Wait until the scan finishes.
If Malwarebytes finds 0 threats congrats! If your MacBook is still slow, then there may be reasons other than malware.

If a virus was detected, click on Confirm button to let Malwarebytes delete the threat, then restart the Mac and run the scan again. If the next scan finds new threats keep restarting and scanning until all threats are gone.
Choosing The Best Antivirus
Is free Malwarebytes a good antivirus? For a long time, I thought so, and I was actually actively recommending it until I did the following test.
I injected my MacBook with 117 malware samples (including Trojans and Ransomware). I tested 13 antivirus products.
The result surprised me – only one product (or two, depending on how you look at it) detected 100% of malware.
You can check the results of my test here: Best Malware Detection App for Mac Removes 117 Viruses In 5 Min
There are other antimalware programs besides MalwareBytes, and many of them are good.
The natural question is which one to choose?
I tried to find the answer, and here are my findings:
There are good several antimalware software choices. The most known are Norton, Intego, Bitdefender, Kaspersky, Trend Micro, Avast, VIPRE.
You can search for rankings published by bloggers, but the thing is they are more likely to promote their affiliate links.
So, how do you choose? The decision depends on your browsing habits.
If you are relatively conservative and cautious when clicking on links, then free AV may be good enough for you. Keep scanning your laptop periodically, and you'll be fine.
If you often visit sites that likely to have malware (torrents, adult, social media) then invest in active protection provided by paid versions.
When choosing the antimalware, consider testing at least two solutions. Then select the one that easier to use. Also, see if it's using too much CPU with the help of Activity Monitor. The last thing you want is an antivirus that slows down the computer.

Does Antivirus Guarantee Protection
Unfortunately, not. There is a term called zero-day vulnerability.
The usual cycle goes like this: someone finds a vulnerability in the software, e.g., in macOS. The first day the vulnerability is found is called zero-day.
The hackers will create software that exploits the vulnerability, and every computer is at risk even the ones that have an antivirus installed.
Then antivirus companies find a solution which needs to be downloaded and installed on the computer. The shorter the period between discovering a vulnerability and the fix fewer computers will be affected.
Bottom line, antimalware products protect from known viruses; they do not protect from malware, which was not written yet.
How To Find Malware Mac
A Side Note On Ransomware
Ransomware is probably the biggest reason why you would want to have active antivirus protection.
With other types of malware: adware, spyware, Trojans, you can download the antimalware software, scan and in most cases, remove the threats.
When you found out about the Ransomware in most cases it's too late: the disk was already encrypted and the time to pay the ransom is ticking. There is no point downloading anti-malware software because it will not be able to decrypt your data.
However, there are exceptions. In some cases, the effects of the Ransomware can be rolled back.
There is a web site nomoreransom.org which was founded by several organizations in order to fight this issue. They have a list of malware that they can help to fix.
First, you have to identify the type of Ransomware you encountered by following their instructions. If the threat is in their list, they will provide decryption tools.

How to prevent Ransomware
While preventing it is hard, there is one thing you can do to minimize the effect. You should invest time in a backup strategy.
The good thing is that Apple has a good backup software called Time Machine. Easiest 3d modeling software. I wrote an article which will teach you how to use it properly:
In case your MacBook was hit by Ransomware all you need is to restore the previous backup and scan for viruses.
Question: Q: How Do You Access Virus Scan On My MacBook Pro ..
Here's What I Do To Stay Secure
- I never open links from emails. If I do, I always check the sender of the email first and then check where the link is pointing to.
- I always submit downloaded packages to VirusTotal before running on my Mac.
- I make backups with Time Machine.
- I save my documents in DropBox. Even if the document was damaged by malware, and the damaged file was uploaded to the cloud, the DropBox keeps a 30-day history of my documents versions, so I can always rollback to the non-damaged version of the document.
- I use Norton 360 Deluxe to scan my MacBook periodically.
- I have automatic updates turned on.
