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.

You consider yourself a responsible person when it comes to taking care of your physical possessions. You’ve never left your wallet in a taxi or lost an expensive ring down the drain. You never let your smartphone out of your sight, yet one day you notice it’s acting oddly.
Did you know that your device can fall into cybercriminals’ hands without ever leaving yours? SIM swapping is a method that allows criminals to take control of your smartphone and break into your online accounts.
Don’t worry: there are a few easy steps you can take to safeguard your smartphone from prying eyes and get back to using your devices confidently.
First off, what exactly is a SIM card? SIM stands for subscriber identity module, and it is a memory chip that makes your phone truly yours. It stores your phone plan and phone number, as well as all your photos, texts, contacts, and apps. In most cases, you can pop your SIM card out of an old phone and into a new one to transfer your photos, apps, etc.
Unlike what the name suggests, SIM swapping doesn’t require a cybercriminal to get access to your physical phone and steal your SIM card. SIM swapping can happen remotely. A hacker, with a few important details about your life in hand, can answer security questions correctly, impersonate you, and convince your mobile carrier to reassign your phone number to a new SIM card. At that point, the criminal can get access to your phone’s data and start changing your account passwords to lock you out of your online banking profile, email, and more.
SIM swapping was especially relevant right after the AT&T data leak. Cybercriminals stole millions of phone numbers and the users’ associated personal details. They could later use these details to SIM swap, allowing them to receive users’ text or email two-factor authentication codes and gain access to their personal accounts.
The most glaring sign that your phone number was reassigned to a new SIM card is that your current phone no longer connects to the cell network. That means you won’t be able to make calls, send texts, or surf the internet when you’re not connected to Wi-Fi. Since most people use their smartphones every day, you’ll likely find out quickly that your phone isn’t functioning as it should.
Additionally, when a SIM card is no longer active, the carrier will often send a notification text. If you receive one of these texts but didn’t deactivate your SIM card, use someone else’s phone or landline to contact your wireless provider.
Check out these tips to keep your device and personal information safe from SIM swapping.
With just a few simple steps, you can feel better about the security of your smartphone, cellphone number, and online accounts. If you’d like extra peace of mind, consider signing up for an identity theft protection service like McAfee+. McAfee, on average, detects suspicious activity ten months earlier than similar monitoring services. Time is of the essence in cases of SIM swapping and other identity theft schemes. An identity protection partner can restore your confidence in your online activities.

For years now, the popularity of online dating has been on the rise—and so have the number of online romance scams that leave people with broken hearts and empty wallets.
In a recent CBS News story, one Texan woman was scammed out of $3,200 by a scammer claiming to be a German Cardiologist. After months of exchanging messages and claiming to be in love with her, he said that he’d been robbed while on a business trip in Nigeria and needed her help.
According to the U.S. Federal Trade Commission (FTC), the reported cost of online romance scams was $1.14 billion in 2023.
Dating and romance scams aren’t limited to online dating apps and sites, they’ll happen on social media and in online games as well. However, the FTC reports that the scam usually starts the same way, typically through an unexpected friend request or a message that comes out of the blue.
With the phony relationship established, the scammer starts asking for money. The FTC reports that they’ll ask for money for several bogus reasons, usually revolving around some sort of hardship where they need a “little help” so that they can pay:
The list goes on, yet that’s the general gist. Scammers often employ a story with an intriguing complication that seems just reasonable enough, one where the romance scammer makes it sound like they could really use the victim’s financial help.
People who have filed fraud reports say they’ve paid their scammer in a few typical ways.
One is by wiring money, often through a wire transfer company. The benefit of this route, for the scammer anyway, is that this is as good as forking over cash. Once it’s gone, it’s gone. The victim lacks the protections they have with other payment forms, such as a credit card that allows the holder to cancel or contest a charge.
Another way is through gift cards. Scammers of all stripes, not just romance scammers, like these because they effectively work like cash, whether it’s a gift card for a major online retailer or a chain of brick-and-mortar stores. Like a wire transfer, once that gift card is handed over, the money on it is highly difficult to recover, if at all.
One more common payment is through reloadable debit cards. A scammer may make an initial request for such a card and then make several follow-on requests to load it up again.
In all, a romance scammer will typically look for the easiest payment method that’s the most difficult to contest or reimburse, leaving the victim in a financial lurch once the scam ends.
When it comes to meeting new people online, the FTC suggests the following:
Scammers, although arguably heartless, are still human. They make mistakes. The stories they concoct are just that. Stories. They may jumble their details, get their times and dates all wrong, or simply get caught in an apparent lie. Also, keep in mind that some scammers may be working with several victims at once, which is yet another opportunity for them to get confused and slip up.
As mentioned above, some romance scammers troll social media and reach out through direct messages or friend requests. With that, there are three things you can do to cut down your chances of getting caught up with a scammer:
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 give a romance scammer less information to exploit.
Be critical of the invitations you receive. Out-and-out strangers could be more than a romance scammer, they could be a fake account designed to gather information on users for purposes of cybercrime, or they can be an account designed to spread false information. There are plenty of them too. In fact, in Q4 of 2023 alone, Facebook took action on 693 million fake accounts. Reject such requests.
Online protection software like ours can help you spot fakes and scams. Features like Text Scam Detector use advanced AI to detect scam links in texts, email, and social media messages before you click. Our Personal Data Cleanup can keep you safer still by removing your personal info from sketchy data broker sites — places where scammers go to harvest useful info on their victims. And if the unfortunate happens, we offer $2 million in identity theft coverage and identity restoration support.
If you suspect that you’re being scammed, put an end to the relationship and report it, as difficult as that may feel.
Notify the FTC at ReportFraud.ftc.gov for support and next steps to help you recover financially as much as possible. Likewise, notify the social media site, app, or service where the scam occurred as well. In some cases, you may want to file a police report, which we cover in our broader article on identity theft and fraud.
If you sent funds via a gift card, the FTC suggests filing a claim with the company as soon as possible. They offer further advice on filing a claim here, along with a list of contact numbers for gift card brands that scammers commonly use.
Lastly, go easy on yourself. If you find yourself a victim of online dating or romance fraud, know that you won’t be the first or last person to be taken advantage of this way. By reporting your case, you in fact may help others from falling victim too.
