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.
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.

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:
- Go to the Applications folder via Go > Applications in Finder or using the shortcut Shift + Command + A.
- Scroll through the list and delete any unknown applications.
- Then empty the trash.
The second step you should do is check for browser hijackers and adware extensions:
- Go to Safari > Preferences. See what the Homepage URL is currently set to and correct if needed.
- 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
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:
- Go to System Preferences
- Select Security & Privacy
- Navigate to the FileVault tab
- 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:
- Use the shortcut Shift + Command + G to Go to Folder
- Type ~/Library/Caches and choose Go
- Delete any particular files inside the folder
If you are unsure about deleting cache files manually, use an app like CleanMyMac X:
- Launch CleanMyMac
- Go to System Junk and click Scan
- When the scan is complete, choose Review Details
- Select User Cache Files and pick the caches you'd like to delete
- Click Clean
In addition, CleanMyMac now features a Malware Removal function, using which should become your weekly habit.
- In CleanMyMac, choose the Malware Removal tab
- Click Scan
- 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.
- Go to System Preferences
- Select Security & Privacy
- 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.
Mac Os X Iso
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.

Nmap has supported Mac OS X since 2001, and our support has only improved over time. While Mac users can compile Nmap themselves, we also offer an executable installer. Nmap makes use of Jhbuild and gtk-mac-bundler which are used to build other projects for Mac OS X, such as OpenSSL, libapr, libsvn.. Nmap is also available through systems such as MacPorts and Fink which package Unix software for Mac OS X.
The easiest way to install Nmap and Zenmap on Mac OS X is to useour installer. TheMac OS X section ofthe Nmap download page provides a file namednmap-
, where.dmg
is the version number of the mostrecent release. The
.dmg
file is known as a'disk image'. Installation instructions follow:
Download the file
nmap-
.Double-click the icon to open it. Mac minimize shortcut. (Depending on how you downloaded thefile, it may be opened automatically.).dmg
The contents of the disk image will be displayed. One ofthe files will be a Mac meta-package file named
nmap-
.Open it to start the installer..mpkg
On OS X 10.8 and later, you may see a dialog likeFigure 2.2.
Figure 2.2. Apple Gatekeeper block screen
If this happens, it is necessary to right-click or control-click on the.mpkg
and select 'Open',as shown inFigure 2.3.Figure 2.3. Apple Gatekeeper Open menu
A dialog similar to the first will appear, this time having an'Open' button (shown inFigure 2.4).Click the button to continue.Figure 2.4. Apple Gatekeeper Open screen
Follow the instructions in theinstaller. You will be asked for your password since Nmap installs in a system directory.
Once the installer is finished, eject the disk image bycontrol-clicking on its icon and selecting'Eject'. The disk image may now be placed inthe trash.
See the instructions in the section called 'Executing Nmap on Mac OS X' forhelp on running Nmap and Zenmap after they are installed.
The programs installed by the installer will run on Intel Mac OS X 10.5(Leopard) or later. Users of earlier versions will have to compile fromsource or use a third-party package. Instructions for PowerPC (PPC) Mac systems (which Apple ceased selling in 2006) are available on our wiki.
Compiling Nmap from source on Mac OS X is no more difficult thanon other platforms once a proper build environment is in place.
Compiling Nmap on Mac OS X requiresXcode,Apple's developer tools that include GCC and the rest of the usual buildsystem. Xcode is not installed by default, but can be downloaded free ofcharge from the Mac AppStore. After installing Xcode, open'Preferences', select the'Downloads' tab, and click the'Install' next to 'Command LineTools'.
How To Scan With Mac Os X
Xcode installations don't always include the command line tools. You can install them by opening Xcode from the Applications folder, opening Preferencechoosing the Download
header icon and clicking the Install
button next to 'Command Line Tools'.
Once you have installed Xcode and the command-line tools, follow the compilation instructions found in the section called 'Linux/Unix Compilation and Installation from Source Code'. Note that on some older versions of Mac OS X, you may have to replace the command ./configure with ./configure CPP=/usr/bin/cpp. Also, on some newer Mac OS X versions, the libpcap version of the library provided by Apple may be too old. You may have to configure Nmap with the command ./configure --with-libpcap=included in order to use the compatible version included in Nmap, or you should update the libpcap installed on your machine.
Zenmap depends on some external libraries that do not come withMac OS X, including GTK+ and PyGTK. These libraries have many dependenciesof their own. A convenient way to install all of them is to use athird-party packaging system as described inSection . Once the dependencies areinstalled, follow the instructions in the section called 'Linux/Unix Compilation and Installation from Source Code' toinstall Zenmap as usual.
Another option for installing Nmap is to use a systemwhich packages Unix software for Mac OS X. The two discussed here areFink andMacPorts. See therespective projects' web sites for how to install the packagemanagers.
To install using Fink, run the command fink installnmap. Nmap will be installed as/sw/bin/nmap
. To uninstall use the commandfink remove nmap.
To install using MacPorts, run sudo portinstall nmap. Nmap will be installed as/opt/local/bin/nmap
. To uninstall, runsudo port uninstall nmap.
These systems install the nmap
executable outside the global PATH
. To enable Zenmap tofind it, set the nmap_command_path
variable inzenmap.conf
to /sw/bin/nmap
or/opt/local/bin/nmap
as described inthe section called 'The nmap
Executable'.
The terminal emulator in Mac OS X is calledTerminal, and is located in the directory/Applications/Utilities
. Open it and aterminal window appears. This is where you will type your commands.
By default the root user is disabled on Mac OS X. To run a scan withroot privileges prefix the command name withsudo,asin sudo nmap -sS .You will be asked for a password, which is just your normal loginpassword. Only users with administrator privileges can do this.
Zenmap requires the X11 application tobe installed. If it was not installed by default it may be available asan optional install on the Mac OS X installation discs. Facebook free download for mac.
When Zenmap is started, a dialog is displayed requesting that youtype your password. Users withadministrator privilegesmay enter theirpassword to allow Zenmap to run as the root user and run more advancedscans. To run Zenmap in unprivileged mode, select the'Cancel' button on this authentication dialog.
