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.

Whether it tags along via a smartphone, laptop, tablet, or wearable, it seems like the internet follows us wherever we go nowadays. Yet there’s something else that follows us around as well — a growing body of personal info that we create while banking, shopping, and simply browsing the internet. And no doubt about it, our info is terrifically valuable.
What makes it so valuable? It’s no exaggeration to say that your personal info is the key to your digital life, along with your financial and civic life as well. Aside from using it to create accounts and logins, it’s further tied to everything from your bank accounts and credit cards to your driver’s license and your tax refund.
Needless to say, your personal info is something that needs protecting, so let’s check out several ways you can do just that.
What is personal info? It’s info about you that others can use to identify you either directly or indirectly. Thus, that info could identify you on its own. Or it could identify you when it’s linked to other identifiers, like the ones linked with the devices, apps, tools, and protocols you use.
A prime example of direct personal info is your tax ID number because it’s unique and directly tied to your name. Further instances include your facial image to unlock your smartphone, your medical records, your finances, and your phone number because each of these can be easily linked back to you.
Then there are those indirect pieces of personal info that act as helpers. While they might not identify you on their own, a few of them can when they’re added together. These helpers include things like internet protocol addresses, the unique device ID of your smartphone, or other identifiers such as radio frequency identification tags.
You can also find pieces of your personal info in the accounts you use, like your Google to Apple IDs, which can be linked to your name, your email address, and the apps you have. You’ll also find it in the apps you use. For example, there’s personal info in the app you use to map your walks and runs, because the combination of your smartphone’s unique device ID and GPS tracking can be used in conjunction with other info to identify who you are. Not to mention where you typically like to do your 5k hill days. The same goes for messenger apps, which can collect how you interact with others, how often you use the app, and your location info based on your IP address, GPS info, or both.
In all, there’s a cloud of personal info that follows us around as we go about our day online. Some wisps of that cloud are more personally identifying than others. Yet gather enough of it, and your personal info can create a high-resolution snapshot of you — who you are, what you’re doing, when you’re doing it, and even where you’re doing it, too — particularly if it gets into the wrong hands.
Remember Pig-Pen, the character straight from the old funny pages of Charles Schultz’s Charlie Brown? He’s hard to forget with that ever-present cloud of dust following him around. Charlie Brown once said, “He may be carrying the soil that trod upon by Solomon or Nebuchadnezzar or Genghis Khan!” It’s the same with us and our personal info, except the cloud surrounding us, isn’t the dust of kings and conquerors. They’re motes of info that are of tremendously high value to crooks and bad actors — whether for purposes of identity theft or invasion of privacy.
With all the personal info we create and share on the internet, that calls for protecting it. Otherwise, our personal info could fall into the hands of a hacker or identity thief and end up getting abused, in potentially painful and costly ways.
Here are several things you can do to help ensure that what’s private stays that way:
Square One is to protect your devices with comprehensive online protection software. This defends you against the latest virus, malware, spyware, and ransomware attacks plus further protects your privacy and identity. Also, it can provide strong password protection by generating and automatically storing complex passwords to keep your credentials safer from hackers and crooks who might try to force their way into your accounts.
Further, security software can also include a firewall that blocks unwanted traffic from entering your home network, such as an attacker poking around for network vulnerabilities so that they can “break in” to your computer and steal info.
Also known as a virtual private network, a VPN helps protect your vital personal info and other data with bank-grade encryption. The VPN encrypts your internet connection to keep your online activity private on any network, even public networks. Using a public network without a VPN can increase your risk because others on the network can potentially spy on your browsing and activity.
If you’re new to the notion of using a VPN, check out this article on VPNs and how to choose one so that you can get the best protection and privacy possible. (Our McAfee+ plans offer a VPN as part of your subscription.)
In the U.S., the Social Security Number (SSN) is one of the most prized pieces of personal info as it unlocks the door to employment, finances, and much more. First up, keep a close grip on it. Literally. Store your card in a secure location. Not your purse or wallet.
Certain businesses and medical practices might ask you for your SSN for billing purposes and the like. You don’t have to provide it (although some businesses could refuse service if you don’t), and you can always ask if they will accept some alternative form of info. However, there are a handful of instances where an SSN is a requirement. These include:
Be aware that hackers often get a hold of SSNs because the organization holding that info gets hacked or compromised itself. Minimizing how often you provide your SSN can offer an extra degree of protection.
Protecting your files with encryption is a core concept in data and info security, and thus it’s a powerful way to protect your personal info. It involves transforming data or info into code that requires a digital key to access it in its original, unencrypted format. For example, McAfee+ includes File Lock, which is our file encryption feature that lets you lock important files in secure digital vaults on your device.
Additionally, you can also delete sensitive files with an application such as McAfee Shredder, which securely deletes files so that thieves can’t access them. (Quick fact: deleting files in your trash doesn’t delete them in the truest sense. They’re still there until they’re “shredded” or otherwise overwritten such that they can’t be restored.)
Which Marvel Universe superhero are you? Does it really matter? After all, such quizzes and social media posts are often grifting pieces of your personal info in a seemingly playful way. While you’re not giving up your SSN, you might be giving up things like your birthday, your pet’s name, your first car…things that people often use to compose their passwords or use as answers to common security questions on banking and financial sites. The one way to pass this kind of quiz is not to take it!
A far more direct form of separating you from your personal info is phishing attacks. Posing as emails from known or trusted brands, financial institutions, or even a friend or family member, a scammer’s attack will try to trick you into sharing important info like your logins, account numbers, credit card numbers, and so on under the guise of providing customer service.
How do you spot such emails? Well, it’s getting a little tougher nowadays because scammers are getting more sophisticated and can make their phishing emails look increasingly legitimate. Even more so with AI tools. However, there are several ways you can spot a phishing email and phony websites. Moreover, our McAfee Scam Protection can do it for you.
You can take two steps to help protect your personal info from being at risk via social media. One, think twice about what you share in that post or photo — like the location of your child’s school or the license plate on your car. Two, set your profile to private so that only friends can see it. Social media platforms like Facebook, Instagram, and others give you the option of making your profile and posts visible to friends only. Choosing this setting keeps the broader internet from seeing what you’re doing, saying, and posting, which can help protect your privacy and gives a scammer less info to exploit. Using our Social Privacy Manager can make that even easier. With only a few clicks, it can adjust more than 100 privacy settings across their social media accounts — making them more private as a result.
The “S” stands for secure. Any time you’re shopping, banking, or sharing any kind of personal info, look for “https” at the start of the web address. Some browsers also indicate HTTPS by showing a small “lock” icon. Doing otherwise on plain HTTP sites exposes your personal info for anyone who cares to monitor that site for unsecured connections.
By locking your devices, you protect yourself that much better from personal info and data theft in the event your device is lost, stolen, or even left unattended for a short stretch. Use your password, PIN, facial recognition, thumbprint ID, what have you. Just lock your stuff. In the case of your smartphones, read up on how you can locate your phone or even wipe it remotely if you need to. Apple provides iOS users with a step-by-step guide for remotely wiping devices, and Google offers up a guide for Android users as well.
Theft of your personal info can lead to credit cards and other accounts being opened falsely in your name. What’s more, it can take some time before you even become aware of it, such as when your credit score takes a hit or a bill collector comes calling. By checking your credit, you can fix any issues that come up, as companies typically have a clear-cut process for contesting any fraud. You can get a free credit report in the U.S. via the Federal Trade Commission (FTC) and likewise, other nations like the UK have similar free offerings as well.
Consider identity theft protection as well. A strong identity theft protection package pairs well with keeping track of your credit and offers cyber monitoring that scans the dark web to detect for misuse of your personal info. With our identity protection service, we help relieve the burden of identity theft if the unfortunate happens to you with $2M coverage for lawyer fees, travel expenses, lost wages, and more.
