Macs are known for being generally reliable and secure, but just like any other piece of technology, they also have weak points, which may be taken advantage of by unscrupulous perpetrators. Within the last few years, there have been several reports of malware and virus attacks on Macs, albeit not worsening enough to be considered an epidemic. Still, the fact remains that the threat is out there and Mac users are not totally invulnerable to cyber attacks.

The latest reported Mac threat was the OSX/MaMi. It made the news in January 2018. The malware was designed to install a new root certificate, allowing it to intercept communications, even the encrypted ones. When it gets to successfully route traffic through malicious servers, that’s when it intercepts sensitive information.

Protect your Mac from malware. MacOS has many features that help protect your Mac and your personal information from malicious software, or malware. One common way malware is distributed is by embedding it in a harmless-looking app. You can reduce this risk by using software only from reliable sources. MacOS has built-in antivirus/anti-malware protection, but if you want another means to determine if your Mac is 'infected' I would suggest that you try either Malwarebytes for Macor EtreCheckas the means to do so. There are a few in-built antimalware programs that come along with macOS through which you can check for viruses or malware on your Mac device. XProtect, Gatekeeper, Sandboxing etc are some in-built anti-malware tools that come along with Mac. These tools have the ability to scan the system automatically. Text presented within 'MAC OS Is Infected With Viruses' pop-up: WARNING! MAC OS X is infected with Viruses and other malicious applications. Viruses must be removed and system damage repaired. It is necessary to run the Virus removal procedure immediately, please proceed. If you leave this site your Mac OS X will remain damaged and vulnerable.

Because of threats such as this, it’s imperative that you know of free Mac virus removal methods. Aside from virus removal methods, you should also educate yourself about the signs of malware and virus infection, as well as the most common sources of malicious and dangerous programs.

Is Your Mac Infected? Signs Your Mac Has a Virus

Before we proceed, let’s set things straight first. You probably noticed we mentioned both malware and virus, but take note that they are different. Malware is typically disguised as an app or program that promises to do something good for you or your system, but actually does something bad, such as spy on your online activities and collect sensitive data. Viruses, on the other hand, are bits of codes that penetrate your system in one way or another and designed to mess with your system.

The first step towards Mac virus removal is to of course know if your device has one. Here are some symptoms:

• Your Mac becomes slow and sluggish all of a sudden.
• There’s a new toolbar or plugin in your browser that you don’t remember installing yourself.
• Your searches get redirected to a different site, or to one that looks like a fake version of the real site you intend to visit.
• Every webpage is riddled with ads, including those that you don’t expect to be so.
• Advertisements that are not at all connected to your recent and common searches pop up out of nowhere.

If you notice any of these signs, be cautious and don’t panic. For one, there are many possible reasons for Mac slowdown. You can blame it on junk file and cache overload, or maybe an insufficient RAM. Before you assume the worst, run a Mac scan using a 3rd party cleaning tool to see if there are items that you can get rid of to improve your Mac’s performance. But if the problem persists, then it’s probably a malware or virus indeed.

Where Do Viruses and Malware Come From?

So, where could you have gotten the malware or virus currently wreaking havoc on your Mac? It might have originated from any of these:

• Laced software – Sometimes, legit and innocent programs and files may be laced with malware and viruses. These can range from simple adware that you unconsciously agreed to install on your system to more dangerous ones that are meant to gather important information about you.
• Fake files and programs – Malware and viruses may be disguised as another program — ironically, as an antivirus or anti-malware even. They are also sometimes made to appear in a photo, video, or pdf file that you might have downloaded onto your system unsuspectingly.
• Fake updates and utilities – You may also get malware and viruses by downloading a fake update or system tool for a program or an app on your Mac.
• Unsecured websites – If you don’t see a padlock icon on the URL bar, this means that you’re browsing an unsecured website. Even if the site itself doesn’t have any bad intentions, it can be easily penetrated by malware and viruses, which in turn can enter your system.

Free Protection Against Viruses: The Built-in Mac Tools

Now, you probably think that in order to protect your Mac from these threats and get rid of them should they get into your system, you have to shed a few dollars. Well, how did you think Mac got its reputation for being secure and capable machines? Well because of built-in tools, invisible background protection against malware and viruses. Your Mac has the following:

• File Quarantine – This is a Mac feature that was first introduced in OS X Leopard. When you download a potentially malicious file over a quarantine-aware platform, such as Safari or Mail, that file will be quarantined. When you open the file, you will be asked by macOS if you’re sure you want to open it, warning that it may be dangerous for your system. It will be in your best interest to heed the warning and not open the file.
• Gatekeeper – This basically works like File Quarantine, but for applications. A relatively new program, Gatekeeper was first introduced in Mountain Lion. It is designed to protect your Mac from malware and dangerous app downloads straight from the internet (not from the App Store). Apple gives recognized developers, who make their apps available outside the App Store, a unique Developer ID. If an app was created by a developer without a Developer ID, Gatekeeper will block its installation. The same goes for apps with fake or tampered Developer IDs.
• Xprotect – This is Apple’s built-in Mac virus scan. It was first introduced in Snow Leopard as a built-in feature of File Quarantine. Xprotect was added to scan for malware and viruses that may be embedded within the file downloaded from the internet. If the file is found to be infected, you will be informed so, and you should move it to the Trash.

By taking your Mac’s warnings seriously, you could keep it malware and virus-free.

Safety Precautions to Observe if You Think Your Mac Was Infected

If the File Quarantine, the Gatekeeper, and the Xprotect detected a threat that tried to penetrate your system, you need to be extra cautious when using your Mac until you’re really sure that it’s virus and malware-free.

1. Don’t type passwords. If you suspect that your Mac is infected by a malware or virus, stay away from anything that requires you to type in passwords or login details. Some malware has keyloggers, which can record your login credentials as you type them. Some may even take screenshots, so refrain from copying and pasting passwords from a note or document. Do not click on the Show Password option as well.
2. Stay offline as much as possible. Until you’re completely sure that the threats are fully extinguished, turn off your Mac’s WiFi or disconnect the Ethernet cable. This will prevent unauthorized transfer of data. If possible, use a different device if you really have to go online.
3. Use Activity Monitor to your advantage. If your gut tells you a malware was installed along an update or app, quit that malicious app by pressing Command + Q. You may also choose Quit from the menu. Then, open Activity Monitor, which can be found in Applications > Utilities folder. On the search field at the top right, type in the name of the app you just quit. If it’s still in the list of running programs despite the fact that you’ve already quit it, then your suspicion has just been validated. Select that program, click [X] at the top left of the toolbar, then choose Force Quit.
4. Use the help of third-party Mac cleaners. Tools like Outbyte MacRepair serve as an additional layer of protection on top of Mac’s built-in ones. With these tools, you can scan your Mac for problematic files and apps, allowing you to decide whether to keep them or remove them from your system to ensure optimal and secure performance.
5. Restore from a backup. If you keep your Time Machine backup up-to-date, you can restore a version of your Mac from the time when it was still malware and virus-free.
6. Change your passwords. After you’ve restored an old version of your Mac, consider changing passwords for all of your accounts. This way, even if a malware was able to capture any of your login credentials, they won’t be used to log in to your accounts anymore.
7. Reinstall macOS and apps. Probably the last and final measure you could do to make sure no remnants of malware and virus is left in your system is to reinstall macOS and all of the apps you use.
8. Check with your bank. Call your credit card provider to check if any unauthorized transactions were done using your card. You should also check your bank account if any fund transfer was made without your consent. Tell your credit card provider and bank about the situation as well as to warn them not to approve any unusual transactions. If possible, request for a new card and arrange to have your online account login details changed.

Indeed, your device is equipped with tools to remove Mac virus for free. However, we will never know when unscrupulous developers will be able to create malware and viruses that could hide and escape from those built-in tools. Sure, Apple will once again develop and offer improved versions of their free malware and virus removal tools to fight advanced threats. However, you should also do your part to keep your Mac safe from harm. Make it a habit to scan for malicious files and programs, and stay away from unsecured sites.

how to get rid of malware on macComputer viruses hold a sweet spot between boring, everyday occurrences, dating back to the 70s, and dramatic, science fiction fueled monsters that will haunt us in our new information-driven world.

One may ask, “Do you need antivirus to protect your Mac?” The reality is, all computers, even Macs, are vulnerable to malware (short for malicious software). While Apple takes a lot of security precautions, how secure your Mac is depends on your knowledge of how to check for viruses and how to remove them.

Whether you want to know how to remove virus from MacBook Pro, MacBook Air, or iMac, learning to keep your information safe first is necessary and easy, with a few tips from the professionals.

How to scan your Mac for a virus

Why checking your Mac for viruses is important? If a computer virus was the only thing to watch out for, this world would be a simpler place. Malware, adware, spyware, malicious files, worms, trojans, phishing software, you name it, you should check for it. The old way of thinking was that because there are more PCs than Macs in the world, the “virus people” would focus on them instead of Macs. But, we’re not in the 2000s anymore. In fact, in 2018, Apple moved to the fourth position in global laptop shipments. This means, Macs are no longer shiny white boxes that are meant for fun and entertainment.

Checking Your Mac For Malware

Not only do we run our businesses off Apple devices and different versions of macOS but we also store family photographs, send out sensitive info — and, thanks to cloud computing, each device is synchronized. Unfortunately, this means your Mac could be a far juicier target than the PC sitting in some corner cubicle.

Know what a Mac virus is

Most of us are familiar with recognizing what a virus looks like thanks to its atrocious design and alarming vocabulary. However, not all viruses take the shock-and-scare approach to getting on your Mac. The latest adware could look like an Adobe Flash Player installer, but is, of course, fake. Not only does it trick you into thinking it's something as normal as Flash, but the installed adware then pretends to be a virus scanner. It shows you bogus problems and encourages you to fix them by giving over sensitive information.

Other forms of viruses could look like Microsoft Office files (e.g. Excel sheets, Word documents), Adobe Photoshop add-ons, as well as music and movie files that you get from BitTorrent or other file sharing programs. But the most common file format that a virus takes is a .dmg file, because it was created by Apple itself to help install good software on your computer. Your task in securing your Mac is to look out for .dmg files showing up when you’re trying to install something. If you’re ever trying to download something you know is supposed to be an image, music, movie, or document, but you get a .dmg file instead — that is as red as a red flag gets in terms of viruses. Do yourself a favor and delete that file immediately.

Keep Mac virus sources in mind

When it comes to having your Mac infected by a virus, we probably expect the attack to come from a stranger. Truth be told, a lot of viruses come from our friends, family, and colleagues, who unfortunately became the primary victim and are now unintentionally passing their viruses to you.

A popular malware virus of 2017 was embedded into a Word document — a Mac Word file, not a PC one. In 2018, Apple discovered flaws in their Intel processor chips that could lead to two kinds of very ambitious strains of Mac viruses too. It’s wild to think that even iPads and iPhones can contract malware.

How to check for malware

In an ideal world, scanning for viruses and the other methods for malware removal should be automatic and happen nearly continuously. In reality, you can consider yourself reasonably safe if you scan your Mac close to once a week. Fortunately, there are quite a few ways to make sure you are as protected as possible.

A good start to scan your Mac for viruses is to see whether you have applications installed that you don’t recognize:

1. Go to the Applications folder via Go > Applications in Finder or using the shortcut Shift + Command + A.
2. Scroll through the list and delete any unknown applications.
3. Then empty the trash.

The second step you should do is check for browser hijackers and adware extensions:

1. Go to Safari > Preferences. See what the Homepage URL is currently set to and correct if needed.
2. Then proceed to the Extensions tab and uninstall any you don’t recognize, as they could spy on you, save your private data, and redirect you to their malicious websites.

How to run a Mac virus scanner and stop viruses from stealing your information

Check For Viruses Mac

It’s a common misconception that viruses only happen to people who are gullible, ignorant, or technologically illiterate. The stigma is that hackers prey on people, when in reality, they prey on behavior.

Our basic assumption with Macs is that we expect Apple and our applications to have done all the security work for us. In truth, every user has to adjust their own behavior when using their Mac.

Do you use public WiFi? Consider getting a Virtual Private Network (VPN) to encrypt the connection between your laptop and the external network. Shimo is a great VPN manager app that will help you here. While using it, raw information (whether sensitive or not) can’t be fed to any malicious programs lurking on your Mac, and hackers on the same network won’t be able to decode anything you’re working on.

Speaking of encryption, Macs using OS X Lion or later come with the option to encrypt their hard drives using FileVault 2. Although encryption won’t prevent viruses from entering your computer (for that, you’ll need a scanner), it would still be very helpful in stopping viruses from stealing your information. To turn on FileVault:

1. Go to System Preferences
2. Select Security & Privacy
3. Navigate to the FileVault tab
4. Choose Turn On FileVault

Keep your Mac secure and virus-free

Trademark signs of something being wrong with your Mac: slow processing memory, a bloated disk space, intense CPU usage, and network speed lag. Unfortunately, viruses don’t live in an easy-to-find location like your computer’s desktop. They can be embedded within an application, most notably, your favorite web browser, where it’s easier for them to view what you’re viewing and track what you’re typing. If you kept on seeing weird websites taking over your search bar, it's a sign that your browser has been hijacked. Other applications can get corrupted or infected too, especially if they have particularly weak security systems. Another example could be an email app you use or an open-source application that is behind on their patch upgrades. Check out how to get rid of malware on mac.

If you think one of your applications is infected, a typical knee-jerk reaction would be to delete the whole thing and redownload it. Often, this will do the trick, but there are simpler solutions available. Clearing the application's cache should always be your first step, and, if there are optional hidden files, consider removing them as well.

Scan your Mac for viruses with CMM X

Run an instant malware scan to identify and remove suspicious files from your Mac. There’s no tool that can do it better than CleanMyMac X.

To remove any application’s cache and get rid of Mac malware from the Library folder:

1. Use the shortcut Shift + Command + G to Go to Folder
2. Type ~/Library/Caches and choose Go
3. Delete any particular files inside the folder

If you are unsure about deleting cache files manually, use an app like CleanMyMac X:

1. Launch CleanMyMac
2. Go to System Junk and click Scan
3. When the scan is complete, choose Review Details
4. Select User Cache Files and pick the caches you’d like to delete
5. Click Clean

In addition, CleanMyMac now features a Malware Removal function, using which should become your weekly habit.

1. In CleanMyMac, choose the Malware Removal tab
2. Click Scan
3. Follow the instructions given. Hopefully it should say your Mac is clean most of the time.

Unfortunately, not all viruses are easy-to-understand files that just sit on your computer. Sometimes they are root certificates that intercept your passwords and messages, and send a copy to hackers. To effectively secure yourself from this, only download apps with valid developer certificates. Which ones are those? It’s hard to know but Apple built a feature that could help you here.

1. Go to System Preferences
2. Select Security & Privacy
3. In the Allow apps downloaded from: select App Store and identified developers

You are well on your way to being protected from malware now. But, the truth is, simply avoiding viruses is not enough. You need to be proactive — it’s time to get a virus scanner.

Check viruses like a pro

If you want complete Mac security, there is no better tool than CleanMyMac X, which can effortlessly scan for all the latest viruses, malware, spyware, and more. Just launch the app on the regular basis and click the Smart Scan option to inspect your Mac for any suspicious activity, besides other suggested features for optimization and cleaning out old files.

Remove viruses from Mac completely

Using a tool like CleanMyMac makes getting rid of viruses, of all shapes and formats, very easy. After the scan, it tells you what it’s found and gives you the option to remove it completely right then and there. Additionally, it will give you all kinds of other great options on how to optimize your Mac’s performance.

As mentioned above, hackers who want to steal your information don’t target you specifically, they target your behavior. So, with this in mind, change your behavior when it comes to using your Mac in potentially unsafe ways. Recognize that viruses come and go, all the time, and across many different file formats. If you get a virus, you’re not ruined.

Arm your computer with encryption tools (like FileVault and a VPN), so that your information can’t be stolen. Practice a healthy dose of skepticism when downloading files. But, most importantly, get professional apps that bring you the most results, like CleanMyMac or Shimo — all of which are available on Setapp for your to try free. So get a scan now and see what it says.

Meantime, prepare for all the awesome things you can do with Setapp.
