While Apple goes to great lengths to keep all its devices safe, this doesn’t mean your Mac is immune to all computer viruses. What does Apple provide in terms of antivirus protection? In this article, we will discuss some signs that your Mac may be infected with a virus or malware, the built-in protections that Apple provides, and how you can protect your computer and yourself from threats beyond viruses.
A computer virus is a piece of code that inserts itself into an application or operating system and spreads when that program is run. While viruses exist, most modern threats to macOS come in the form of other malicious software, also known as malware. While technically different from viruses, malware impacts your Mac computers similarly: it compromises your device, data, and privacy.
While Apple’s macOS has robust security features, it’s not impenetrable. Cybercriminals can compromise a Mac through several methods that bypass traditional virus signatures. Common attack vectors include software vulnerabilities, phishing attacks that steal passwords, drive-by downloads from compromised websites, malicious browser extensions that seem harmless, or remote access Trojans disguised as legitimate software.
Understanding the common types of viruses and malware that target macOS can help you better protect your device and data. Here’s a closer look at the most prevalent forms of malware that Mac users should watch out for.
Whether hackers physically sneak it onto your device or by tricking you into installing it via a phony app, a sketchy website, or a phishing attack, viruses and malware can create problems for you in a couple of ways:
Is your device operating slower, are web pages and apps harder to load, or does your battery never seem to keep a charge? These are all signs that you could have a virus or malware running in the background, zapping your device’s resources.
Malware or mining apps running in the background can burn extra computing power and data, causing your computer to operate at a high temperature or overheat.
If you find unfamiliar apps you didn’t download, along with messages and emails that you didn’t send, that’s a red flag. A hacker may have hijacked your computer to send messages or to spread malware to your contacts. Similarly, if you see spikes in your data usage, that could be a sign of a hack as well.
Malware can also be behind spammy pop-ups, unauthorized changes to your home screen, or bookmarks to suspicious websites. In fact, if you see any configuration changes you didn’t personally make, this is another big clue that your computer has been hacked.
Your browser’s homepage or default search engine changes without your permission, and searches are redirected to unfamiliar sites. Check your browser’s settings and extensions for anything you don’t recognize.
Your antivirus software or macOS firewall is disabled without your action. Some viruses or malware are capable of turning off your security software to allow them to perform their criminal activities.
Fortunately, there are easy-to-use tools and key steps to help you validate for viruses and malware so you can take action before any real damage is done.
Macs contain several built-in features that help protect them from viruses:
There are a couple of reasons why Mac users may want to consider additional protection on top of the built-in antivirus safeguards:
Macs are like any other connected device. They’re also susceptible to the wider world of threats and vulnerabilities on the internet. For this reason, Mac users should think about bolstering their defenses further with online protection software.
If you suspect your Mac has been infected with a virus or other malware, acting quickly is essential to protect your personal data and stop the threat from spreading. Fortunately, this can be effectively done with a combination of manual steps and trusted security software:
In the most extreme cases, erasing your hard drive and reinstalling a fresh copy of macOS is a very effective way to eliminate viruses and malware. This process wipes out all data, including the malicious software. This, however, is considered the last resort for deep-rooted infections that are difficult to remove manually.
As cyber threats grow more sophisticated, taking proactive steps now can protect your device, your data, and your identity in the long run. Here are simple but powerful ways to future-proof your Mac, and help ensure your device stays protected against tomorrow’s threats before they reach you:
Staying safe online isn’t just about having the right software—it’s about making smart choices every day. Adopting strong digital habits can drastically reduce your risk of falling victim to viruses, scams, or data breaches.
An important part of a McAfee’s Protection Score involves protecting your identity and privacy beyond the antivirus solution. While online threats have evolved, McAfee has elevated its online protection software to thwart hackers, scammers, and cyberthieves who aim to steal your personal info, online banking accounts, financial info, and even your social media accounts to commit identity theft and fraud in your name. As you go about your day online, online protection suites help you do it more privately and safely. Comprehensive security solutions like McAfee+ include:
Yes. While Safari has built-in security features, you can still get a Mac virus by visiting a compromised website that initiates a drive-by download or by being tricked into downloading and running a malicious file.
Not necessarily. Many websites use aggressive pop-up advertising. However, if you see persistent pop-ups that are difficult to close, or fake virus warnings, it’s a strong sign of an adware infection.
Yes. While some consider it less harmful than a trojan, adware is a form of malware. It compromises your browsing experience, tracks your activity, slows down your computer, and can serve as a gateway for more dangerous infections.
If you have a security suite with real-time protection, your Mac is continuously monitored. It is still good practice to run a full system scan at least once a week for peace of mind.
Direct infection via a cable is extremely unlikely due to the security architecture of both operating systems. The greater risk comes from shared accounts. A malicious link or file opened on one device and synced via iCloud, or a compromised Apple ID, could affect your other devices.
Current trends show a rise in sophisticated adware and PUPs that are often bundled with legitimate-looking software. Cybercriminals are also focusing on malicious browser extensions that steal data and credentials, injecting malicious code into legitimate software updates, or devising clever ways to bypass Apple’s notarization process. Given these developments, Macs can and do get viruses and are subject to threats just like any other computer. While Apple provides a strong security foundation, their operating systems may not offer the full breadth of protection you need, particularly against online identity theft and the latest malware threats. Combining an updated system, smart online habits, and a comprehensive protection solution helps you stay well ahead of emerging threats. Regularly reviewing your Mac’s security posture and following the tips outlined here will also enable you to use your device with confidence and peace of mind.

New online threats emerge every day, putting our personal information, money and devices at risk. In its 2024 Internet Crime Report, the Federal Bureau of Investigation reports that 859,532 complaints of suspected internet crime—including ransomware, viruses and malware, data breaches, denials of service, and other forms of cyberattack—resulted in losses of over $16 billion—a 33% increase from 2023.
That’s why it is essential to stay ahead of these threats. One way to combat these is by conducting virus scans using proven software tools that constantly monitor and check your devices while safeguarding your sensitive information. In this article, we’ll go through everything you need to know to run a scan effectively to keep your computers, phones and tablets in tip-top shape.
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.
Each antivirus program works a little differently, but in general the software will look for known malware with specific characteristics, as well as their variants that have a similar code base. Some antivirus software even checks for suspicious behavior. If the software comes across a dangerous program or piece of code, the antivirus software removes it. In some cases, a dangerous program can be replaced with a clean one from the manufacturer.
Before doing a virus scan, it is useful to know the telltale signs of viral presence in your device. Is your 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? Maybe you’re seeing unexpected pop-up windows, or experiencing crashes and other program errors. These are just some signs that your device may have a virus, but don’t get too worried yet because many of these issues can be resolved with a virus scan.
Free virus scanner tools, both in web-based and downloadable formats, offer a convenient way to perform a one-time check for malware. They are most useful when you need a second opinion or are asking yourself, “do I have a virus?” after noticing something suspect.
However, it’s critical to be cautious. For one, cybercriminals often create fake “free” virus checker tools that are actually malware in disguise. If you opt for free scanning tools, it is best to lean on highly reputable cybersecurity brands. On your app store or browser, navigate to a proven online scanning tool with good reviews or a website whose URL starts with “https” to confirm you are in a secure location.
Secondly, free tools are frequently quite basic and perform only the minimum required service. If you choose to go this path, look for free trial versions that offer access to the full suite of premium features, including real-time protection, a firewall, and a VPN. This will give you a glimpse of a solution’s comprehensive, multi-layered security capability before you commit to a subscription.
If safeguarding all your computers and mobile devices individually sounds overwhelming, you can opt for comprehensive security products that protect computers, smartphones and tablets from a central, cloud-based hub, making virus prevention a breeze. Many of these modern antivirus solutions are powered by both local and cloud-based technologies to reduce the strain on your computer’s resources.
This guide will walk you through the simple steps to safely scan your computer using reliable online tools, helping you detect potential threats, and protect your personal data.
When selecting the right antivirus software, look beyond a basic virus scan and consider these key features:
The process of checking for viruses depends on the device type and its operating system. Generally, however, the virus scanner will display a “Scan” button to start the process of checking your system’s files and apps.
Here are more specific tips to help you scan your computers, phones and tablets:
If you use Windows 11, go into “Settings” and drill down to the “Privacy & Security > Windows Security > Virus & Threat Protection” tab, which will indicate if there are actions needed. This hands-off function is Microsoft’s own basic antivirus solution called Windows Defender. Built directly into the operating system and enabled by default, this solution provides a baseline of protection at no extra cost for casual Windows users. However, Microsoft is the first to admit that it lags behind specialized paid products in detecting the very latest zero-day threats.
Mac computers don’t have a built-in antivirus program, so you will have to download security software to do a virus scan. As mentioned, free antivirus applications are available online, but we recommend investing in trusted software that is proven to protect you from cyberthreats.
If you decide to invest in more robust antivirus software, running a scan is usually straightforward and intuitive. For more detailed instructions, we suggest searching the software’s help menu or going online and following their step-by-step instructions.
Smartphones and tablets are powerful devices that you likely use for nearly every online operation in your daily life from banking, emailing, messaging, connecting, and storing personal information. This opens your mobile device to getting infected through malicious apps, especially those downloaded from unofficial stores, phishing links sent via text or email, or by connecting to compromised wi-fi networks.
Regular virus scans with a mobile security software are crucial for protecting your devices. Be aware, however, that Android and IOS operating systems merit distinct solutions.
Antivirus products for Android devices abound due to this system’s open-source foundation. However, due to Apple’s strong security model, which includes app sandboxing, traditional viruses are rare on iPhones and iPads. However, these devices are not immune to all threats. You can still fall victim to phishing scams, insecure Wi-Fi networks, and malicious configuration profiles. Signs of a compromise can include unusual calendar events, frequent browser redirects, or unexpected pop-ups.
Apple devices, however, closed platform doesn’t easily accommodate third-party applications, especially unvetted ones. You will most likely find robust and verified antivirus scanning tools on Apple’s official app store.
Before you open any downloaded file or email attachment, it’s wise to check it for threats. To perform a targeted virus scan on a single file, simply right-click the file in Windows Explorer or macOS Finder and select the “Scan” option from the context menu to run the integrated virus checker on a suspicious item.
For an added layer of security, especially involving files from unknown sources, you can use a web-based file-checking service that scans for malware. These websites let you upload a file, which is then analyzed by multiple antivirus engines. Many security-conscious email clients also automatically scan incoming attachments, but a manual scan provides crucial, final-line defense before execution.
Once the scan is complete, the tool will display a report of any threats it found, including the name of the malware and the location of the infected file. If your antivirus software alerts you to a threat, don’t panic—it means the program is doing its job.
The first and most critical step is to follow the software’s instructions. It might direct you to quarantine the malicious file to isolate the file in a secure vault where it can no longer cause harm. You can then review the details of the threat provided by your virus scanner and choose to delete the file permanently, which is usually the safest option.
After the threat is handled, ensure your antivirus software and operating system are fully updated. Finally, run a new, full system virus scan to confirm that all traces of the infection have been eliminated. Regularly backing up your important data to an external drive or cloud service can also be a lifesaver in the event of a serious infection.
The most effective way to maintain your device’s security is to automate your defenses. A quality antivirus suite allows you to easily schedule a regular virus scan so you’re always protected without having to do it manually. A daily quick scan is a great habit for any user; it’s fast and checks the most vulnerable parts of your system. Most antivirus products regularly scan your computer or device in the background, so a manual scan is only needed if you notice something dubious, like crashes or excessive pop-ups. You can also set regular scans on your schedule, but a weekly full scan is ideal.
These days, it is essential to stay ahead of the wide variety of continuously evolving cyberthreats. Your first line of defense against these threats is to regularly conduct a virus scan. You can choose among the many free yet limited-time products or comprehensive, cloud-based solutions.
While many free versions legitimately perform their intended function, it’s critical to be cautious as these are more often baseline solutions while some are malware in disguise. They also lack the continuous, real-time protection necessary to block threats proactively.
A better option is to invest in verified, trustworthy, and all-in-one antivirus products like McAfee+ that, aside from its accurate virus scanning tool, also offers a firewall, a virtual private network, and identity protection. For complete peace of mind, upgrading to a paid solution like McAfee Total Protection is essential for proactively safeguarding your devices and data in real-time, 24/7.

AI, a term that might sound intimidating to many, is not so when we understand it. It is essentially technology that can be programmed to achieve certain goals without assistance. In simple words, it’s a computer’s ability to predict, process data, evaluate it, and take necessary action. This smart way of performing tasks is being implemented in education, business, manufacturing, retail, transportation, and almost every other industry and cultural sector you can think of.
AI has been doing a lot of good too. For instance, Instagram, the second most popular social network, is now deploying AI technology to detect and combat cyberbullying in both comments and photos. No doubt, AI is having a significant impact on everyday life and is poised to metamorphose the future landscape. However, alongside its benefits, AI has brought forward a set of new challenges and risks. From self-driving cars malfunctioning to potential jobs lost to AI robots, from fake videos and images to privacy breaches, the concerns are real and need timely discussions and preventive measures.
AI has made it easier for people to face-swap within images and videos, leading to “deep fake” videos that appear remarkably realistic and often go viral. A desktop application called FakeApp allows users to seamlessly swap faces and share fake videos and images. While this displays the power of AI technology, it also brings to light the responsibility and critical thinking required when consuming and sharing online content.

More importantly, change the default password on these devices and secure your primary network along with your guest network with strong passwords.
Having an open dialogue about AI and its implications is key to navigating through the intricacies of this technology. Parents need to have open discussions with kids about the positives and negatives of AI technology. When discussing fake videos and images, emphasize the importance of critical thinking before sharing any content online. Possibly, even introduce them to the desktop application FakeApp, which allows users to swap faces within images and videos seamlessly, leading to the production of deep fake photos and videos. These can appear remarkably realistic and often go viral.
Privacy is another critical area for discussion. After the Cambridge Analytica/Facebook scandal of 2018, the conversation about privacy breaches has become more significant. These incidents remind us how our private (and public) information can be misused for financial or political gain. Locking down privacy settings, being mindful of the information shared, and understanding the implications of reactions and comments are all topics worth discussing.
Awareness and knowledge are the best tools against AI-enabled cybercrime. Making families understand that bogus emails can now be highly personalized and can trick even the most tech-savvy users into clicking malicious links is essential. AI can generate phishing emails, scamming people into handing over sensitive data. In this context, constant reminders to be cautious with every click, even those from known sources, are necessary.
