Since DMG file is a disk image its safety depends on its contents. DMG files are neither safe or unsafe, but they may contain viruses or malware inside. When downloading from the internet always make sure that the web site you are downloading is from a trusted developer. Downloading a DMG file does not compromise Mac security. An image file with a name beginning in 'Screen Shot' should be saved to the Desktop. Open the screenshot and make sure it's readable. If not, capture a smaller part of the screen showing only what needs to be shown. Start a reply to this message. Drag the image file into the editing window to upload it. You can also include text in the reply. To open a.dmg file in Windows 10, we turned to 7-Zip, an open-source tool that can be used to extract files on Windows. Alternatives like DMG Extractor should also be considered if 7-Zip doesn.

The more macOS grows in popularity, the more lucrative it becomes to hackers and rogue programmers, and with no anti-virus, your MacBook is at risk of attack. Viruses on Mac are more common than you might imagine. We're going to run through known Mac viruses, malware, and security flaws and show you how to keep your computer safe using CleanMyMac X.

Something to note before we continue: a virus is a type of malware, capable of copying itself and spreading across a system. Malware is a blanket term for a wide range of malicious software including adware, spyware, ransomware, and Trojans. So all viruses are malware, but not all malware are viruses if that makes sense?

Okay, let's dig in.

How a Mac virus infects your system

How does a Mac virus find its way onto your system in the first place? Typically with a helping hand from you.

Apple viruses rely on you downloading a program, clicking a link, or installing an app or plugin.

The most common ways for malware to infiltrate your computer is through third-party browser plugins like Adobe Reader, Java, and Flash, or by using a Trojan horse or phishing scam — an app or email that appears to be from a legitimate source, but is in fact fraudulent. The moment you click on a link and enter details or download the seemingly genuine app, you give the green light for a virus to infect your system.

The best way to avoid a virus on Mac is to be vigilant. Double check every app that you want to download and every email that you receive before following through on an action. If something seems off, there's every chance that it is.

However, as you'll see from some of the viruses, in certain cases even vigilance can't protect you.

Known Mac viruses

1. Microsoft Word macro viruses

What's that, a Microsoft program bringing its virus-riddled programs over to Mac? Unfortunately, yes.

Macros are commonly used by Word users to automate repetitive tasks and they're a prime target for Malware peddlers. Macro support on Mac was removed by Apple with the release of Office for Mac back in 2008, but was reintroduced in 2011 meaning files opened with macros enabled could run a Python code to log keystrokes and take screenshots of personal data.

In 2017, Malwarebytes discovered malware in a Word document about Donald Trump to the worry of Mac users. However, the chances of being infected rely on you opened that specific file, which is slim.

A warning message that Apple displays anytime a file contains macros should be enough to keep you safe from Word macro viruses.

2. Safari-get

Safari-get is a denial-of-service (DoS) attack that began targeting Mac in 2016. The malware is hidden behind a link in a seemingly genuine tech support email — you click on the link, the malware makes itself at home on your computer.

What happens then depends on whether you're running macOS 10 or 11. The first variant takes control of the mail application to force create multiple draft emails. The second force opens iTunes multiple times. The end goal for both is the same: overload system memory to bring your Mac to its knees so that you call up a fake Apple tech support number and hand over your credit card details to a bogus team on the other end of the line.

MacOS High Sierra versions 10.12.2 and above include a patch for this vulnerability, so updating your machine should keep you safe.

3. OSX/Pirrit

OSX/Pirrit is a virus that is able to gain root privileges to take it upon itself to create a new account and download software that you neither want nor need. The virus was found by Cybereason to be hidden in cracked versions of Adobe Photoshop and Microsoft Office that are popular on torrent sites.

A stark reminder, if ever you needed one, to never download pirated software!

Known Mac malware

1. OSX/MaMi

OSX/MaMi holds the distinction of being the first macOS malware of 2018. It targets Mac users with social engineering methods such as malicious emails and website pop-ups. Once it's made its way onto a system, the malware changes DNS server settings so that attackers can route traffic through malicious servers and intercept any sensitive data. MaMi is also capable of taking screenshots, downloading and uploading files, executing commands, and generating mouse events.

The Hacker News provides instructions on how to identify the virus on your system:

'To check if your Mac computer is infected with MaMi malware, go to the Terminal via the System Preferences app and check for your DNS settings—particularly look for 82.163.143.135 and 82.163.142.137.'

2. OSX/Dok

This piece of Malware is a worrying one in that it is signed with an Apple-authenticated developer certificate, thus allowing it to bypass Mac's Gatekeeper security feature and XProtect. Like OSX/MaMi, OSX/Dok intercepts all traffic (including traffic on SSL-TLS encrypted websites) moving between your computer and the internet to steal private information.

Since it arrived on the scene in April 2017, Apple has revoked the developer certificate and updated XProtect, however, it remains one to look out for.

3. Fruitfly

Fruitfly malware has stolen millions of user images, personal data, tax records and 'potentially embarrassing communications over a 13 year period by capturing screenshots and webcam images. Researchers are unsure how the near-undetectable 'creepware' finds its way on to Mac systems and while Apple has been working to patch the issue, it's unknown if newer versions still exist in the wild.

Check simple info (type and uid) from NFC tags, credit cards and nfc-enabled phones via the Pro controller and Joy-Con (R) Edit analog sticks user calibration. Edit the analog stick's X/Y ranges and centers. All controllers are supported.

4. X-agent

X-agent is classic malware capable of stealing your passwords and iPhone backups and taking screenshots of sensitive data. It has mainly targeted members of the Ukrainian military, which is very bad, of course, but if you're not a member of Ukrainian military you're unlikely to be affected.

5. MacDownloader

While its name suggests it could be a useful app, MacDownloader is a very nasty piece of malware programmed to attack the US defense industry. It's hidden inside a fake Adobe Flash update and shows a pop-up claiming your system is infected with adware. By clicking on the alert and entering your admin password, MacDownloader lifts sensitive data, including passwords and credit card details, and sends it to a remote server.

MacDownloader is designed to attack a particular audience, but it's worth checking for updates on Adobe's official website before installing any new version of Flash.

6. KeRanger

KeRanger is macOS's first introduction to ransomware — malware that encrypts system files and demands a ransom to decrypt them. It was bundled in with the torrent client Transmission version 2.90 and installed at the same time, using a valid Mac app certificate to sneak through Apple security. Once document and data files are encrypted, KeRanger demands payment in bitcoin for the malware to be removed.

Transmission has released an update to remove the malware and Apple has removed KeRanger's GateKeeper signature to protect users. If you're using Transmission 2.90, head over to the Transmission website to download the latest update.

Known Mac security flaws

1. Goto fail bug

The Goto fail bug was a bit of an embarrassing one for Apple in that the security flaw was as a result of its own doing. A bug in Apple's SSL (Secure Sockets Layer) encryption meant that a Goto command was left unclosed in the code, thus preventing SSL from doing its job to protect users of secure websites. The flaw put communications sent over unsecured Wi-Fi (the hotspots you use at the mall and in coffee shops) at risk, allowing hackers to intercept passwords, credit card details, and other sensitive information.

Apple has since patched the issue on macOS, but it certainly makes you think twice about how you browse the web on your MacBook in a public place.

2. Meltdown and Spectre

In January 2018, it was announced that there was a flaw in Intel chips used in Macs, giving rise to the dastardly duo of Meltdown and Spectre.

From Apple:

The Meltdown and Spectre issues take advantage of a modern CPU performance feature called speculative execution. Speculative execution improves speed by operating on multiple instructions at once—possibly in a different order than when they entered the CPU. To increase performance, the CPU predicts which path of a branch is most likely to be taken, and will speculatively continue execution down that path even before the branch is completed. If the prediction was wrong, this speculative execution is rolled back in a way that is intended to be invisible to software.

The Meltdown and Spectre exploitation techniques abuse speculative execution to access privileged memory—including that of the kernel—from a less-privileged user process such as a malicious app running on a device.

Meltdown and Spectre affects all Mac systems, but Apple insists there are no known exploits currently impacting customers. macOS 10.13.2 and above includes a patch to protect against both flaws.

3. High Sierra 'root' bug

As far as security flaws go, High Sierra's 'root' bug is a pretty big one. The flaw, which was discovered by software developer Lemi Orhan Ergin, allowed anyone to gain root access to a system by leaving the password field blank and trying multiple times in a row. So, anyone with physical access to your system, or access via remote desktop or screen-sharing, could type in 'root' and hit enter a few times to gain full control of your Mac. Scary thought, huh?

Apple has recently released an official fix for the flaw, but it's worth taking care about who shares access privileges on your Mac.

How to recognize a virus on Mac

So how do you spot a virus on your MacBook Pro or iMac? In the case of ransomware like KeRanger or a DoS attack like Safari-get, the issue is in your face. With other malware, however, the infection is less obvious.

A few of the tell-tale signs include:

• Unexpected system reboots
• Apps closing and restarting for no reason
• Browsers automatically installing suspicious updates
• Web pages obscured with ads
• Drop in system performance

How to avoid a virus on Mac

We briefly covered this at the top of the article, but there are measures you can take to help safeguard your system:

• Always check the source of an email by looking at the address of the sender
• Avoid pirated software
• Avoid software and media downloads from torrent clients
• Avoid apps or pop-ups that ask you to 'fix' an infected Mac
• Never download codecs or plug-ins from unknown websites
• How to remove a virus on Mac

If you suspect a Mac virus has infected your system, it's important to address the problem immediately. There are two ways that you can do this: manually or with CleanMyMac X.

How to remove a virus on Mac manually

To remove a virus manually, the first thing to do is find out what's causing the problem.

The chances are it could be a downloaded file, so go to your Downloads folder and search for .DMG files. If the file is unfamiliar, delete it and empty the Trash.

If an app is the issue, go to your Applications, drag the icon of the culprit to the Trash bin and empty the Trash immediately.

Both of these methods offer a quick fix, but neither is the most comprehensive of solutions. The way in which viruses work means that the infection could have spread to system folders. If the problem persists, opt for the more robust CleanMyMac 3.

How to remove malware on Mac with CleanMyMac X

CleanMyMac X is designed to detect and remove malware threats from your Mac, including adware, spyware, ransomware, worms, and more.

If malware is lurking within your Mac, it won't be after CleanMyMac is done with it.

1. Download CleanMyMac X (free download) and launch the app.
2. Click on the Malware Removal tab.
3. Click Scan.
4. Click Remove.

This app is actually notarized by Apple so you are safe using it. Speaking of malware, it has a real-time monitor that keeps an eye on your Launch Agents. If an unknown app tries to add itself into your system folders, you'll get an instant notification from CleanMyMac X.

Keep your Mac virus-free

For the most part, using a Mac is a pleasant, malware-free experience, but no computer is ever 100% virus-free. Keeping abreast of known Mac viruses so that you know what to look for and airing on the side of caution when downloading software will help keep your system running smoothly. And if a rogue app does make its way on your system, keep CleanMyMac X close to hand to remove it immediately and completely.

What is DMG file

A DMG File stands for Disk Image file and it is a file format which is used to create mountable disks on the Macintosh operating system. The DMG File format contains data in the form of blocks which are often secured using encryption methods or are compressed using compression algorithms. DMG files are used for installing tools and softwares into the Mac OS operating system. The file is downloaded from the internet from the software manufacturer's website and upon mounting the DMG file, a virtual disk is generated from where the user can either copy the application to the applications folder or run an installation script depending on the type of installation.

You can try to run these tool to fix the error The disc image file is corrupted.

The newer disk image file was used in place of the original IMG or image file which was used in earlier versions of mac that are classic mac operating systems. Disk Image Files are only meant to be used in Mac based systems and not on the Windows operating systems. However, using some image softwares like Daemon tools on windows, we can mount disk images of DMG type on windows too. Some tools can also convert DMG Files to windows-recognizable image files like .ISO files.

Mar 08, 2019 A DMG file is a mountable disk image created in macOS. It contains raw block data typically compressed and sometimes encrypted. DMG files are commonly used for macOS software installers that are downloaded from the Internet, which mount a virtual disk on the desktop when opened. Dmg file download. After installing DMG Extractor, all you have to do is double-click your DMG file to open it up. You can browse the files right in the DMG Extractor window if you just want to see what's inside the DMG file. Sep 07, 2019 How to Open DMG Files. This wikiHow teaches you how to open a DMG file on a Mac. Since DMG files are used predominately to install applications on Macs, you cannot properly open DMG files on Windows computers.

Recover lost or deleted iOS data and passcodes Explore + extract data from iOS backups & devices Download iCloud photos & data Manage & backup your iPhone and iPad Work with DMG files on Windows Get data from BlackBerry backups.

Benefits of DMG Disk Image format

1. DMG Images are read only which ensures that the files inside the installer are not altered with. This makes the software supplied inside the dmg secure from viruses as no one can alter the file after it is created.
2. Instead of sending more than one file over the internet, the creators have to send a single dmg disk image which contains all the required installation files of the software that can be simply dragged and dropped into the applications folder of Mac to install them.
3. DMG files can be customized according to the manufacturer's wish so that the installers look pleasing when people download the files for installing software.
4. Disk images can be mounted on a computer just like a physical cd. This is a good thing as people can save a copy of the DMG file as a backup which can be used later to restore the previous state of the files.

What is ISO File

An ISO file stands for International Organization for Standardization file format which specified ISO as the standard file format for disk image files in Windows. It is a file which can be used to mount disk image files in Windows operating systems. It can be used to emulate a CD, DVD or any other disk drive in Windows virtually.

It is generally used to hold disk images of operating systems like linux which can be burned into a disk or a USB drive. It is also used to send installation files of Windows softwares through the internet but they are usually sent through a binary package with an executable or an msi installer.

Basically ISO files are an image of something so you could have an image of a computer software package that would be all the files that existed on that computer software in one finite image. You can also burn that image file to a CD because these are optical images.

How to Convert DMG File to ISO

The ISO file format can be used on the Macintosh operating systems, however, almost all of the software packages for Mac is downloaded from the internet as a DMG Disk Image file. Although the DMG file format has some features which are not available in the ISO format like file encryption methods and compression algorithms, DMG files cannot be used anywhere else instead of a Mac. This is why we may need to convert DMG FIles to the ISO File format.

Corrupted Image Files

To convert dmg to iso file on Windows, you should install third party softwares like PowerISO. It is a disk image burning software that can be used to convert DMG File to ISO on Windows. You can also directly burn DMG Files to a CD/DVD using this software.

Before downloading PowerISO, check the system requirements that is required to install and run Power ISO.
