The big question out there when it comes to Apple products is, 'Can a Mac get a virus?' The short answer? Absolutely.
Apple computers can get viruses and malware just like PCs can. While iMacs, MacBooks, Mac Minis, and iPhones may not be as frequent targets as Windows computers, all have their fair share of threats.
Adware, spyware, ransomware, and hardware and software vulnerabilities are some of the problems now affecting Macs, and not just PCs. Read on to learn more about some of the most common malware and viruses that can affect Apple devices, what the signs are, and what you can do to help protect your devices.
Four types of Apple viruses — and a vulnerability
Apple viruses can range from annoying to outright damaging.
1. Adware on Macs
Adware is a potentially unwanted program that can bombard users with advertising pop-ups. Adware can be both malicious or benign. Some adware can work in conjunction with spyware, a type of software that can spy on and record everything you do online.
Pop-up ads can lead users to malicious websites that could deliver data-stealing spyware onto their Macs. Adware can also send information back to a third-party server. This information could be used to commit crimes, such as identity theft, fraud, or even extortion.
Although they're not malicious, even benign pop-up ads can be extremely annoying and intrusive.
2. Trojan horses on Macs
Trojan horses are common to Macs and PCs. One notable Apple computer Trojan horse was found in February 2017. Dubbed 'MacDownloader,' it was malicious software hiding in a fake Adobe Flash update.
The MacDownloader malware was a form of spyware that attempted to steal personal data, including the user's keychain, which stores usernames, passwords, PINs, credit card numbers, and more.
3. Macro viruses on Macs
Microsoft Word macro viruses have been around for a long time, mainly affecting PCs, but eventually jumping over to the Mac OS.
Macro viruses go to work when a user opens an infected file with macros enabled. The macro then tries to run a code that could perform functions such as taking screenshots and even accessing webcams.
Macro viruses are capable of creating new files, corrupting data, moving text, sending files, formatting hard drives, and inserting pictures, among other things. How to reduce the size of a png on mac. One of their more popular uses is to deliver destructive viruses and malware.

Ransomware is finally here for the Mac. KeRanger was one of the first significant ransomware outbreaks for Macs. As its name implies, ransomware presents users with an ultimatum: pay a fee to unlock their computer or specific files to reclaim personal data. If users don't pay the price, they risk losing the data forever.
Macs can have software and hardware vulnerabilities, too
Software and hardware vulnerabilities can affect all devices, no matter their maker. You may have heard of a major vulnerability last year dubbed Meltdown and Spectre.

This was a particular form of malware that affected the processor chips of PCs and Macs. This hardware vulnerability allowed programs to steal data that was currently being processed on the computers' chip. This included data like your passwords stored in a password manager or browser, emails, personal documents, photos, and instant messages. All of these types of information were vulnerable until the right software patches were installed.
How to tell if your Mac has a virus
If you have a feeling that your Mac is behaving oddly or is just 'off,' you may have a virus. Strange activity, applications seeming to 'lag' when opening, and more can all be warning signs you may have malicious software on your Mac.
1. Ads and pop-ups are popping up often.
This could be a sign of adware. Being bombarded with a slew of advertisements every time you perform an action on your computer should be a signal that it's time to run a virus scan. Signs may include unusual amounts of banner ads, or fake pop-ups that recommend updates to your computer.
2. Your computer is slow.

2. Your computer is slow.
Mac users are familiar with what is referred to as the 'spinning wheel of death.' That's when the cursor turns into a rainbow wheel. This is a sign of a sluggish computer. That little wheel means that your Mac is working overtime, trying to do too many things at once. When this happens, it could mean there's a malicious program running in the background you may not know about.
3. You have browser issues.
Did your browser suddenly change its homepage to something you've never seen before? If your browser is unresponsive, or starts crashing regularly, you might have a virus.
4. Nothing at all.
That may sound odd, but it's true. A lot of malware aims to be installed without the user's knowledge and to run quietly in the background. This is why installing strong antivirus software is crucial for Macs, as it can detect threats you may not be able to.
Do Macs need antivirus software?
Antivirus software is kind of like insurance for your car or house. You may not need it all the time, but when trouble comes calling, you'll be glad you have it. While it's true that Macs have historically been considered to be less vulnerable to malware attacks than PCs, there are still significant threats out there. Adding an extra layer of device protection, like Norton Security Deluxe, is one way to help stay ahead of the curve.

Whether you think you might have a virus on your computer or devices, or just want to keep them running smoothly, it's easy to do a virus scan. How you perform the virus scan depends on the software you have, so we'll go through a few options below. But first, let's cover a few telltale signs that you might may have a virus.
Do You Need A Virus Scan?
Is your computer or device acting sluggish, or having a hard time booting up? Have you noticed missing files or a lack of storage space? Have you noticed emails or messages sent from your account that you did not write? Perhaps you've noticed changes to your browser homepage or settings? Or maybe, you're seeing unexpected pop-up windows, or experiencing crashes and other program errors. These are all signs that you may have a virus, but don't get too worried yet, because many of these issues can be resolved with a virus scan.

What Does A Virus Scan Do, Exactly?
Each antivirus program works a little differently, but in general the software will look for known malware that meets a specific set of characteristics. It may also look for variants of these known threats that have a similar code base. Some antivirus software even checks for known, suspicious behavior. If the software comes across a dangerous program or piece of code, it removes it. In some cases, a dangerous program can be replaced with a clean one from the manufacturer.
How Do You Run A Scan?
On a Windows Computer:
If you are using the latest version of Windows, Windows 10, go into 'Settings' and look for the 'Updates & Security' tab. From there you can locate a 'Scan Now' button.
Of course, many people have invested in more robust antivirus software that has a high accuracy rate and causes less drain on their system resources, such as McAfee Total Protection. To learn how to run a virus scan using your particular antivirus software, search the software's 'help' menu, or look online for exact instructions.

On a Mac Computer:
Computers running Mac software don't have a built-in antivirus program, so you will have to download security software to do a virus scan. There are some free antivirus applications available online, but we always recommend investing in trusted software that can protect you from a variety of threats. Downloading free software can be risky, since cybercriminals know that this is a good way to spread malware.

On Smartphones & Tablets:
Yes, you can get the virus on your phone or tablet, although they are less common than on computers. However, the wider category of mobile malware is on the rise and your device can get infected if you download a risky app, click on an attachment in a text message, visit a dangerous webpage, or connect to another device that has malware on it.
Fortunately, you can protect your devices with mobile security software. It doesn't usually come installed, so you will have to download an application and follow the instructions.
Because the Android platform is an open operating system, there are a number of antivirus products available for Android devices, allowing you to do a virus scan.
Apple devices are little different, however, because they have a closed operating system that doesn't allow third parties to see their code. Although Apple has taken other security precautions to reduce malware risks, such as only allowing the installation of apps from Apple's official app store, these measures aren't the same as an antivirus program.

All-In-One Protection:
If safeguarding all your computers and devices sounds overwhelming, you can opt for a comprehensive security product that protects computers, smartphones and devices from a central control center, making virus prevention a snap.
Why are virus scans so important?
New online threats emerge every day, putting our personal information, money, and devices at risk. In the first quarter of last year alone McAfee detected 504 new threats per minute, as cybercriminals adopted new tactics. That's why it is essential to stay ahead of these threats by using security software that is constantly monitoring and checking for new known threats, while safeguarding all of your sensitive information. Virus scans are an essential part of this process when it comes to identifying and removing dangerous code.
How Often Should You Do A Virus Scan?
Most antivirus products are regularly scanning your computer or device in the background, so you will only need to start a manual scan if you notice something suspicious, like crashes or excessive pop-ups. You can also program regular scans on your schedule.
Preventing Viruses
Of course, the best protection is to avoid getting infected in the first place. Here are a few smart tips to avoid viruses and other malware:
- Learn how to surf safe so you can avoid risky websites, links, and messages. This will go a long way in keeping you virus-free.
