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.

How do you recognize phishing emails and texts? Even as many of the scammers behind them have sophisticated their attacks, you can still pick out telltale signs.
Common to them all, every phishing is a cybercrime that aims to steal your sensitive info. Personal info. Financial info. Other attacks go right for your wallet by selling bogus goods or pushing phony charities.
You’ll find scammers posing as major corporations, friends, business associates, and more. They might try to trick you into providing info like website logins, credit and debit card numbers, and even precious personal info like your Social Security Number.
Phishing scammers often undo their own plans by making simple mistakes that are easy to spot once you know how to recognize them. Check for the following signs of phishing when you open an email or check a text:
It’s poorly written.
Even the biggest companies sometimes make minor errors in their communications. Phishing messages often contain grammatical errors, spelling mistakes, and other blatant errors that major corporations wouldn’t make. If you see glaring grammatical errors in an email or text that asks for your personal info, you might be the target of a phishing scam.
The logo doesn’t look right.
Phishing scammers often steal the logos of the businesses they impersonate. However, they don’t always use them correctly. The logo in a phishing email or text might have the wrong aspect ratio or low resolution. If you have to squint to make out the logo in a message, the chances are that it’s phishing.
The URL doesn’t match.
Phishing always centers around links that you’re supposed to click or tap. Here are a few ways to check whether a link someone sent you is legitimate:
You can also spot a phishing attack when you know what some of the most popular scams are:
The CEO Scam
This scam appears as an email from a leader in your organization, asking for highly sensitive info like company accounts, employee salaries, and Social Security numbers. The hackers “spoof”, or fake, the boss’ email address so it looks like a legitimate internal company email. That’s what makes this scam so convincing — the lure is that you want to do your job and please your boss. But keep this scam in mind if you receive an email asking for confidential or highly sensitive info. Ask the apparent sender directly whether the request is real before acting.
The Urgent Email Attachment
Phishing emails that try to trick you into downloading a dangerous attachment that can infect your computer and steal your private info have been around for a long time. This is because they work. You’ve probably received emails asking you to download attachments confirming a package delivery, trip itinerary, or prize. They might urge you to “respond immediately!” The lure here is offering you something you want and invoking a sense of urgency to get you to click.
The “Lucky” Text or Email
How fortunate! You’ve won a free gift, an exclusive service, or a great deal on a trip to Las Vegas. Just remember, whatever “limited time offer” you’re being sold, it’s probably a phishing scam designed to get you to give up your credit card number or identity info. The lure here is something free or exciting at what appears to be little or no cost to you.
The Romance Scam
This one can happen completely online, over the phone, or in person after contact is established. But the romance scam always starts with someone supposedly looking for love. The scammer often puts a phony ad online or poses as a friend-of-a-friend on social media and contacts you directly. But what starts as the promise of love or partnership, often leads to requests for money or pricey gifts. The scammer will sometimes spin a hardship story, saying they need to borrow money to come visit you or pay their phone bill so they can stay in touch. The lure here is simple — love and acceptance.
Account Suspended Scam
Some phishing emails appear to notify you that your bank temporarily suspended your account due to unusual activity. If you receive an account suspension email from a bank that you haven’t opened an account with, delete it immediately, and don’t look back. Suspended account phishing emails from banks you do business with, however, are harder to spot. Use the methods we listed above to check the email’s integrity, and if all else fails, contact your bank directly instead of opening any links within the email you received.
While you can’t outright stop phishing attacks from making their way to your computer or phone, you can do several things to keep yourself from falling for them. Further, you can do other things that might make it more difficult for scammers to reach you.
The content and the tone of the message can tell you quite a lot. Threatening messages or ones that play on fear are often phishing attacks, such as angry messages from a so-called tax agent looking to collect back taxes. Other messages will lean heavily on urgency, like a phony overdue payment notice. And during the holidays, watch out for loud, overexcited messages about deep discounts on hard-to-find items. Instead of linking you off to a proper e-commerce site, they might link you to a scam shopping site that does nothing but steal your money and the account info you used to pay them. In all, phishing attacks indeed smell fishy. Slow down and review that message with a critical eye. It might tip you off to a scam.
Some phishing attacks can look rather convincing. So much so that you’ll want to follow up on them, like if your bank reports irregular activity on your account or a bill appears to be past due. In these cases, don’t click on the link in the message. Go straight to the website of the business or organization in question and access your account from there. Likewise, if you have questions, you can always reach out to their customer service number or web page.
Some phishing attacks occur in social media messengers. When you get direct messages, consider the source. Consider, would an income tax collector contact you over social media? The answer there is no. For example, in the U.S. the Internal Revenue Service (IRS) makes it clear that they will never contact taxpayers via social media. (Let alone send angry, threatening messages.) In all, legitimate businesses and organizations don’t use social media as a channel for official communications. They’ve accepted ways they will, and will not, contact you. If you have any doubts about a communication you received, contact the business or organization in question directly. Follow up with one of their customer service representatives.
Some phishing attacks involve attachments packed with malware, like ransomware, viruses, and keyloggers. If you receive a message with such an attachment, delete it. Even if you receive an email with an attachment from someone you know, follow up with that person. Particularly if you weren’t expecting an attachment from them. Scammers often hijack or spoof email accounts of everyday people to spread malware.
How’d that scammer get your phone number or email address anyway? Chances are, they pulled that info off a data broker site. Data brokers buy, collect, and sell detailed personal info, which they compile from several public and private sources, such as local, state, and federal records, plus third parties like supermarket shopper’s cards and mobile apps that share and sell user data. Moreover, they’ll sell it to anyone who pays for it, including people who’ll use that info for scams. You can help reduce those scam texts and calls by removing your info from those sites. Our Personal Data Cleanup scans some of the riskiest data broker sites and shows you which ones are selling your personal info.
Online protection software can protect you in several ways. First, it can offer web protection features that can identify malicious links and downloads, which can help prevent clicking them. Further, features like our web protection can steer you away from dangerous websites and block malware and phishing sites if you accidentally click on a malicious link. Additionally, our Scam Protection feature warns you of sketchy links in emails, texts, and messages. And overall, strong virus and malware protection can further block any attacks on your devices. Be sure to protect your smartphones in addition to your computers and laptops as well, particularly given all the sensitive things we do on them, like banking, shopping, and booking rides and travel.
