For many years, Apple fans who used Mac computers claimed that their computers couldn't get infected by a virus. But can you get a virus on Mac? The simple answer is yes.

A virus is nothing more than a computer program that gets installed on your computer. Instead of doing something productive like a spreadsheet program or a web browser, a Mac virus is an application that attempts to do something malicious to your computer.

Why Macs are Less Likely to Get Viruses

A phishing scam has targeted Mac users by redirecting them from legitimate websites to fake websites which tell them that their computer is infected with a virus. The user is then offered Mac Defender 'anti-virus' software to solve the issue. This “anti-virus” software is malware (i.e. Malicious software&rpar. Hi, I recently made the switch from Avast to AVG on my Mac and have been having trouble with the program. My preferred use of Antivirus (while not recommended, I know) is to keep it disabled and only use it to scan when I want to at my convenience.

As the use of Mac computers became more mainstream, more hackers started turning their attention toward programming virus that could attack Mac computers.

It is a little harder to circumvent Mac OS security, but it isn't impossible. How do Macs protect users better than the Windows OS does?

• File Checking: Whenever you attempt to download a file to your Mac, the Mac operating system scans the file for malware.
• Approved Software: You aren't allowed to install applications on your Mac that haven't already been approved by Apple and are digitally signed. However, users can bypass this protection by holding down the Ctrl key when opening the app.
• Xprotect: Whenever you attempt to open an application, Mac's Xprotect tool automatically scans the application to see if it's on Apple's list of known malicious software.
• Automatic Updates: Unlike Windows computers where users can either slow down or even entirely disable updates. On a Mac, all updates happen automatically, keeping the system immediately up to date and patched whenever Apple identifies vulnerabilities.
• Sandboxing: Approved Apple applications are blocked from performing any actions that aren't approved by Apple.
• Safari Anti-Phishing: Safari, the default Mac browser, has anti-phishing technology built-in that detects fraudulent websites and blocks the page from loading. The browser only allows the latest version of plug-ins like Flash, QuickTime, Java, and Silverlight.

These challenges cause most hackers to turn to writing Windows viruses instead, because Windows is easier to manipulate. However there are some hackers that feel compelled to focus on writing Mac viruses because of its growing user base.

The Most Common Mac Viruses

We know Macs can get viruses because in recent years there have been major ones.

How To Do A Spyware Scan On My Mac

The following are the most common malicious applications that still remain a threat to Mac systems across the world.

Avast Mac Security offers three shields and on-demand scanning. Our Web Shield and Mail Shield combine to check the vast majority of incoming data from the Internet, while File Shield scans all programs stored and executed from your hard drive. Avast for mac upgrade keeps popping up. What's New in Avast Mac Security.

• Word Macro Viruses: Word macros are scripts that run inside word, but macro viruses will actually log keystrokes or steal private information off the computer.
• Safari Viruses: One major threat to Safari users is a piece of malware known as Safari-get. Once your computer is infected with it (usually by clicking a bad web link), the virus will overload your Mac and attempt to freeze it with a window displaying a fake Apple tech support number in order to steal your credit card information.
• Pirrit: Hidden inside cracked versions of Adobe Photoshop and Microsoft Office, this virus is able to gain root privileges and download additional malicious software.
• Dok: This malware will intercept all web traffic in order to scrape your private or sensitive information.
• Fruitfly: This malware, once on your system, will steal files like images, sensitive records, and other files by capturing screenshots and even taking images from the computer webcam.
• MaMi: First introduced in 2018, the path of infection is usually either malicious website ads or email phishing attempts. The software alters DNS settings to redirect web traffic and capture sensitive information.

There have been other Mac viruses through the years. In some cases they were simply scareware meant to make users believe their systems were hacked when they weren't. But what this list makes clear is that a mac can get a Trojan virus, malware, worms, and any other threat that Windows users face.

How to Protect Your Mac from Viruses

Since there are many protections already in place if you own a Mac, staying safe from these threats is fairly easy.

The best way to avoid malware and viruses from infecting your Mac is to stick to only using approved software from the Mac store.

The following actions will further ensure your Mac stays clean.

• Browser Updates: Keeping Safari fully updated will ensure you have the latest versions of Java, Silverlight, and other browser add-ons. These are sure to have the latest patches that will protect you from any viruses.
• App Updates: Keep all apps that you use on your Mac fully updated. This will prevent any new security vulnerabilities from becoming a threat to your Mac.
• Beware Phishing: When you receive an email with a link, be very wary about clicking on it. If it's from a company you do business with, avoid clicking the email link and log into the company website directly instead.
• Avoid Social Ads: Social media is fast becoming one of the most commonly used platforms by hackers. Avoid clicking on ads on Facebook and elsewhere. If a friend sends you an 'interesting video', avoid the temptation to click it.
• Don't Install Flash: Since HTML5 has made Flash obsolete, there's little reason to install Flash Player at all. Flash is a significant security risk, and keeping it off your system will greatly improve your security.

How to Remove a Mac Virus

Avast for mac standalone. If you do find your Mac infected with a virus, there are a few things you can do to clean a virus from your Mac.

• Downloaded Files: Viruses most commonly come from downloaded files. So the first thing you'll want to do is go to your downloads folder and clear it out. Remember to empty the trash after.
• Delete New Apps: If you recently installed a new app, go to Applications and drag the icon to the Trash bin, then empty the trash.
• Uninstall New Extensions: If a malicious browser extension is the cause, find recently installed extensions in your browser and uninstall them.
• Malwarebytes: This application is one of the most successful at removing adware, malware, and viruses. Install Malwarebytes for Mac and run a full scan on your system.

The most important thing you can do, whether or not you've been infected, is to install antivirus software for your Mac. There are a number of very good antivirus apps available for Mac. Choose one, and install it.

What Is System Scan On My Mac

As we talked about in last week’s Working Mac, you may have been led to believe that you don’t have to worry about computer viruses on your Mac. And, to some extent, there’s truth to that. While your Mac can definitely be infected with malware, Apple’s built-in malware detection and file quarantine capabilities are meant to make it less likely that you’ll download and run malicious software.

How Do I Do A Virus Scan On My Mac

Apple introduced malware detection to the Mac OS with Snow Leopard (Mac OS 10.6). This system consists of the quarantine of any app downloaded from the Internet, the use of Code Signing certificates to verify that an app is coming from a legit source, and regular security updates that include databases of known malware targeting the Mac OS.

Because of this system, called File Quarantine and occasionally referred to as XProtect:

• Apps in quarantine display a dialog window reminding you where the app came from and asking whether or not you’re sure you want to open it.

• Apps with no code signing certificate, depending on your Gatekeeper settings, may display a message saying the app can’t be opened because of your settings. (For software you know is good you can bypass this by control-clicking the app and selecting Open from the resulting contextual menu.)

• Apps that are known malware cannot be opened at all. You’ll be met with a message offering the option to toss the app in the trash.

And this is why Macs remain mostly virus and malware free.

To make sure your Mac malware database is always up to date you’ll want to verify that your Mac always automatically installs security updates and related system data files.

To do this:

1. Open System Preferences
2. Open the App Store preference
3. Make sure that Automatically check for updates and Install system data files and security updates are checked.

This should keep your Mac free from most malicious software, although it’s important to note that it does not make it impossible for malicious software to be installed on your Mac. There is no software that’s able to catch everything. If new malware is released today and you download and run it today you will have done so before Apple’s databases could have been updated. So it’s always best to be wise when downloading software from unknown sources.

While it’s unlikely that your Mac will run any malware, there is possibly a more pernicious issue: You Mac could become the Typhoid Mary Windows viruses, which is to say, you could be harboring viruses on your Mac that won’t effect you, but can be problems for Windows users.

Think I’m joking? Have a look at this screenshot, taken from my Mac during the course of writing this column:

That, my friends, is a list of 30 potentially bad things that..you guessed it, were found on my Mac while I was running a test virus scan, one of which is a Windows virus. And, nope, I did not plan this, even though I did plan to write about this problem.

So, how do you keep your Mac from relaying Windows viruses to Windows users?

ClamXav.

Why ClamXav? Because it has one job and it does it very well. It’s not too intrusive. It doesn’t try to do too much. If you’re using Apple’s Server app to host your email, it’s what Apple uses to scan incoming mail for viruses.

ClamXav is, like AdWare Medic, donationware and it is fantastic. You’ll find it at the Mac App Store or you can download it directly from the ClamXav Website, where you can also make a donation.

Once you’ve downloaded and opened the app you’ll want to set the app’s preferences, as the default behavior is to scan for viruses but not delete or quarantine them. ClamXav offers five configuration options:

• General: For setting up alerts and whether or not to scan for malware and phishing in your email messages (which is where the app found infected files on my Mac)
• Quarantine: For defining where you want to quarantine malicious files
• Exclude Files: To specify file types you don’t want scanned
• Log Files: For setting whether or not you want log files stored and for viewing them
• Schedule: For defining when you want the latest virus definitions downloaded and when you want scheduled scans to take place

Once you’ve finished your setup, click the Start Scan button and go grab some milk and cookies. Scanning may take awhile, but when it’s done you’ll know for sure your Mac is clean.
