Best antivirus for Windows PC in 2026: 7 apps to keep your PC safe

11/10 03:15 - Best antivirus for Windows PC in 2026: 7 apps to keep your PC safe
You need antivirus software. Because of AI, online threats keep getting more sophisticated—more and more AI-fueled attacks pop up with each passing week. Even the tech-savvy and cautious can get tricked into exposing themselves to malware, spyware, ransomware, or a phishing attack. This guide compares the best Windows antivirus suites, including when Windows Security is enough and when extra privacy, parental, or identity tools make a paid suite worth it. Make sure you understand how all our picks differ before settling on any one choice. For instance, Norton is great for all around value, but Avast is great for ease of use, AVG for budget buyers, Avira Prime for beginners, McAfee for the privacy-conscious, and Panda for a surfeit of features. Not to mention what Windows Security brings to the table at no cost at all. Why you should trust PCWorld for antivirus reviews: PCWorld has been deep in the trenches of testing computer hardware, software, and services since 1983—including security suites. As users of PC hardware and software, we run all products through rigorous testing, with plenty of hands-on evaluation and benchmarks (when the later is applicable). We don’t recommend gear or apps we wouldn’t use ourselves. Best antivirus of 2026 reviewed and ranked Norton 360 Deluxe – Best antivirus for PC overall Pros Strong antivirus protection Wide protection against major online threats Simple, straightforward features Cons Performance impact on some PCs User interface would benefit from consolidation Upselling of additional services Best Prices Today: Retailer Price $49.99 View Deal Price comparison from over 24,000 stores worldwide Who should buy Norton 360 Deluxe? Norton 360 Deluxe works for everyone—it consolidates all the biggest protections you need online into one affordable package, including parental controls. If you have trouble keeping up with security experts’ recommendations (or haven’t yet gotten around to following all of them), this suite centralizes and simplifies it all. That’s how it won out as our pick for the best antivirus software of 2026. This plan has just about everything most PC users need, without extra bloat. For antivirus performance, Norton offers strong online protection, while having minimal impact on system resources if you don’t often download or copy large amounts of files. Additionally, you get malicious link and attachment screening, dark web and privacy monitoring, and webcam safeguards. Norton also tosses in 50GB of storage for cloud backups, access to Norton’s password manager and VPN, parental controls, and PC utilities that include the ability to monitor for outdated software. And those major extras—the password manager, VPN, and parental controls—have easy, simple interfaces, without feeling stripped to the bone. Norton 360 Deluxe: Further Considerations As part of its efforts to consolidate online security protections into a single software interface, Norton sports a refreshed user interface. It also began promising better scam protection at the beginning of the year, in addition to its other features. And despite all this value, its pricing remains very reasonable. For the first year, you’ll pay $50 for five devices, and then $120 per year thereafter.

For those seeking utter ease of use, Avast One not only offers solid protection, but a simple, friendly interface. Combine that together with useful extra features and multi-device coverage, and you have a winning combo. In addition to top-ranked antivirus protection, it offers safeguards against remote webcam takeovers, malicious websites, and trackers. The Avast One plan also includes dark web monitoring, a VPN with unlimited bandwidth, and protections for saved passwords to a browser. You get utilities to help you keep your PC’s drivers up to date, clean up your PC, and optimize your apps, too. These features may sound standard, and to be fair, many of them can be found in rival software. But Avast makes staying on top of security dead simple, whether you’re a novice or a security veteran. Its default settings require little input to keep your PC protected, and if you want to dig in further or tinker, you still have that option, too. Avast One: Further Considerations Unlike Norton 360 Deluxe (our top pick), Avast One does not come with a password manager, nor parental controls. As a result, it doesn’t cost as much. You have the option of the 1+1 device plan (PC and mobile) for $38.99/yr ($77.99 thereafter); or you can cover 10 devices for $49.99/yr ($99.99 thereafter). Read our full Avast One review AVG Internet Security – Best budget antivirus suite Pros Top-rated antivirus protection Expanded protection against malicious websites and remote attacks Clean, straightforward interface Cons Some PCs may experience a performance hit during heavier workloads Several features are a bit rudimentary Who should buy AVG Internet Security? AVG is best known for its excellent free antivirus software, but there’s good reason to upgrade. AVG Internet Security not only offers more comprehensive protection, but also easy management of those tools. That user-friendly interface is valuable if you find keeping up with online threats too overwhelming or time consuming. The Internet Security plan builds upon the free version’s top-ranked protection against malware and web, email, and network threats. It also guards the passwords saved to your browsers; webcam takeovers; unknown access to files with sensitive data; malicious redirects for websites you’re trying to visit (aka DNS hijacking); and Windows Remote Desktop attacks. Dark web monitoring is included as well. And the app has minimal impact on system resources when monitoring your system in the background, though full scans can hit budget or older systems harder. AVG Internet Security: Further Considerations AVG Internet Security costs just $60 during the first year for 10 devices, with the fee rising to $100 thereafter. The price is fair, especially given the deeper control and more expansive protection compared to the free version. But without elements like parental controls, VPN, and a password manager, it doesn’t provide the same value as Norton 360 Deluxe. Read our full AVG Internet Security review Avira Prime – Best antivirus for beginners Pros Strong security with a reasonable subscription price Well designed and user-friendly Offers a host of features in the areas of security, privacy, and performance Cons No subscription option for fewer than five devices Simplicity of app feels slightly at odds with the depth of the PC tools Best Prices Today: Retailer Price Avira Operations GmbH $59.99 View Deal Price comparison from over 24,000 stores worldwide Who should buy Avira Prime? Avira Prime is one of the best choices for those seeking more help with managing their PC, thanks to its simple, clear interface and feature lineup. In addition to to solid antivirus protection, it offers a password manager, unlimited VPN, and a boatload of PC utilities that (among other things) can keep apps up to date, securely delete files, and back up data. Thise security suite will best suit users seeking a simple antivirus suite, broad online protections, and robust PC utilities—and also want to use those latter tools for more confident management of their computer. Not every utility is a winner, but the overall set can help you identify and understand the more technical aspects of Windows and system upkeep. Avira Prime: Further Considerations The one major feature missing from Avira Prime is a set of parental controls. You can’t use it to filter web content or monitor device usage. The app also can hit older and budget PCs hard when full scans are running, if you’ve added or changed large amounts of files. But typically, it only minimally affects system performance when left to run in the background, so most people won’t notice Avira running. For the first year, you’ll pay $60 for the first year, and then $105 for every year after. That first-year cost is slightly higher than our overall top pick, but if you prefer more newbie-friendly software, it’s worth the extra ten bucks. Read our full Avira Prime review McAfee Total Protection – Best antivirus for privacy Pros Good protection Nice features like file shredder and home network analyzer Cons Mixed impact on performance New app design is a little scattered Best Prices Today: Retailer Price $89.99 View Deal Price comparison from over 24,000 stores worldwide Who should buy McAfee Total Protection? Your personal information can be used against you online—and with data breaches so painfully common these days, it can be a relief to have help in tracking who has your info. For anyone who doesn’t have as much time to handle that work themselves, or even keep track of a separate service, McAfee Total Protection can serve as a central spot for managing all your online security concerns. Total Protection hunts down current threats to PCs, with solid results. These days, dangers extend beyond just malware to identity and privacy issues, and this app addresses these just as much as it does ransomware and phishing sites. That ID protection makes it stand out against competitors, especially if you pay to scale up the service. The plan we tested included dark web scanning for multiple pieces of personal information (email address, phone number, social security number, passport, driver’s license, date of birth, tax ID, credit card, usernames, and more). The app also offers to help change your password for online accounts, when applicable. VPN access is included as well. McAfee Total Protection: Further Considerations Mid-tier and budget machines can see impact on system resources when running McAfee scans. When we ran a full scan during a variety of common tasks (web browsing, document editing, etc), we noticed some dips in performance. You can mitigate this effect by timing scans for off hours, however. Currently, McAfee Total Protection is available through third-party sellers (McAfee has turned its attention to its slightly newer McAfee+ plans on its website). We like this version still because of how extremely affordable it is—for example, a license on PCWorld’s own software site is just $19 per year, which covers up to 10 devices for one year. Read our full McAfee Total Protection review Panda Dome Complete – Most feature-rich antivirus Pros Very easy-to-understand mobile-like interface Contains some basic smart home network monitoring Month-to-month pricing option Cons Good performance results but currently limited in third-party testing Best Prices Today: Retailer Price Panda Security $30.10 View Deal Price comparison from over 24,000 stores worldwide Who should buy Panda Dome Complete? All deluxe antivirus suites offer extra tools as part of their package, but Panda Dome Complete particularly stands out. It also has one of the most striking interfaces we’ve seen, while still putting everything right at your fingertips. Similar to Microsoft’s Bing homepage, Panda Dome features a beautiful background photo, with the interface elements placed on top of it. A whole raft of utilities come with this suite, including a virtual keyboard, advanced virus removal, an update manager for your Windows apps, a disk defragmenter, hard drive cleaner, and startup apps manager. You also get Wi-Fi protection (which lets you see what devices are connected to your network), a password manager, parental controls, and a VPN that offers 150 megabytes of bandwidth per day. In addition to offering reliable antivirus protection, Panda had the most minimal impact on system performance during our benchmarks. So minor, in fact, that in the real-world it worked out to no difference. Panda Dome Complete: Further Considerations As one of the most feature-rich offerings, Panda Dome Complete is among the more expensive options. You can purchase a subscription for $54 during the first year ($90 per year afterward), but that’s covers just one device. Fortunately, it only costs a little more to upgrade to a three device plan ($55 for the first year, $100 per year afterward) or five device plan ($54 for the first year, $110 per year afterward). Read our full Panda Dome Complete review Windows Security (Microsoft Defender) – Best free antivirus for Windows Pros Built into Windows 10 and 11 Settings are easy to review and customize Integrates with other security aspects of Windows Cons Tends toward false positives, especially with SmartScreen Lacks the advanced features found in third-party products Who should choose Windows Security? Windows’ built-in security suite is an excellent free antivirus option—as we discovered in our roundup of the best free antivirus—even if its protection isn’t quite as strong as third-party rivals when your PC is offline. It bundles together Defender, which monitors for viruses and malware; Firewall, which blocks malicious incoming traffic and suspicious outgoing traffic; ransomware protections (including controlled access to folders, as well as data recovery via OneDrive integration); app restrictions; and even basic parental controls. The most important of these protections are automatically enabled in Windows—you don’t have to lift a finger to get real-time antivirus scanning or network protection. You will have to manually switch on some features, though, including ransomware folder controls and file recovery. You can find more features in other antivirus suites, like online privacy tools, a VPN, and encrypted cloud backups. But this free protection comes preinstalled on Windows machines and does a good job of keeping you protected from most threats. Windows Security: Further Considerations To coax the most out of Windows Security, you will have to configure it. (See this Windows Security primer to learn more.) You’ll also need to separately choose and manage additional security services for optimum online protection—e.g., privacy tools, VPN, password manager, and encrypted cloud backup. Read our full Windows Security review Other antivirus software tested Surfshark One: This VPN software includes adequate antivirus protection with a clean, simple interface, but you’ll get more bang for your buck (and a lighter hit to your PC’s system resources) by choosing rival security software with a stronger focus on antivirus protection. McAfee+ Ultimate: This comprehensive all-in-one package offers strong antivirus protection and a vast array of online protections, but its apps, services, and tools could use more polish. Its scans also can tangibly decrease performance on mid-range and budget PCs. Avast Premium Security: You can choose a couple of different paths when upgrading from Avast’s already excellent free antivirus software—and this branch of the company’s software leans hard into safeguarding your PC. However, a couple of buggy features keep this suite from standing out among its rivals. Bitdefender Total Security: Superb antivirus defenses are packed into an easy-to-use app that includes a unique safe payment environment. However, it lacks some features you get with similarly priced suites, like a password manager. Malwarebytes Premium Security: Technology newbies will like this antivirus software’s simplicity, but you can get more bang for your buck elsewhere. Norton Antivirus Plus: Its one-device limitation is tight, but this simplified antivirus suite is affordable and offers more features than similar rivals. If you can work comfortably with its quirks and potentially heavy performance effect, it can be ideal software for digital minimalists. Trend Micro Maximum Security: Even when you can count on Trend Micro Maximum Security to work, this beginner-friendly antivirus suite feels underbaked. You can find much stronger malware protection, along with a more robust set of features, in rival software—and often at a lower price. How we test antivirus software Our approach to testing antivirus software is multi-pronged—we look not just at how well the suite catches malware and other threats (though that’s certainly a top factor), but other elements as well. First, we spend some time in the interface, to determine if it’s simple or complex to use. Ideally, it should take just a click or two to find vital tools like PC scanning, and also the password manager and VPN (if included). Elements that are clickable should be clear, too. And alerts should make sense — you should both understand what they are telling you and they should be relevant to what you’re doing. We also look at the available features. Reputable antivirus suites should include basics like real-time protection and deeper scans. Better subscription plans will also add on a password manager or a firewall. Overall, we try to figure out if the extras are helpful, or just another marketing bullet point. To evaluate how hard an antivirus app will hit your PC’s system resources, we run several benchmarks. The first is PCMark 10’s Extended test, which simulates various workloads, including editing documents, web browsing, video chatting, and light gaming. Second is UL Procyon, focusing on document editing in Microsoft Office apps—e.g., Word, Excel, PowerPoint. Then, as the most punishing test, we run Handbrake to transcode a large video into a smaller one. This encoding task often utilizes 100 percent of the CPU on many home PCs.When performing benchmarks, we first run all three tests on our Windows 11 PC before installing the antivirus suite under review. Then we install the app and run the benchmarks again, as an approximation of how the app behaves while running in the background. Finally, we open the software and fire up full scans continuously while running each benchmark again. Afterward, we compare the scores to look for any decline, and note the amount. Currently, the laptop we use for testing is an Acer Aspire 3 15 with an AMD Ryzen 5 7520U, 8GB RAM, and a 512GB SSD. We use a clean install of Windows 11 when testing each security suite. For calculating an antivirus suite’s detection abilities, we rely on the testing of dedicated security researchers. Most often, we look at reports from organizations like AV Comparatives and AV Test. We also evaluate pricing for each subscription, as well as the features you get for the price. Generally, we do the bulk of our testing using free trials to understand what customers will actually see. Any review codes provided by companies are used to take clean screenshots for the review (i.e. free of reminders to upgrade or buy). For even more details about our review process (and the philosophy behind why we test as we do), you can also read our full explanation about our antivirus testing practices.

How to choose the best antivirus software When shopping for antivirus software, you want to be mindful of the must-haves versus the nice-to-haves. The former consists of core protection and usability features: If an antivirus program doesn’t offer the following three things, it’s doing it wrong: High detection rate for malware and other threats, both online and offline Low use of system resources A simple, clear interface Beyond that, it’s up to you what other additional features are necessary from your antivirus. Security suites now come packed with extras like a backup service for essential files, mobile apps for Android and iOS, advanced firewall features, content restriction and GPS location for family members, and the ability to install the app on multiple computers. Access to a VPN and a password manager have become more common, too. Your budget and personal situation will dictate if you need these additional features. If you’re looking to go beyond the basics, our baseline recommendation is to find a suite that comes with a firewall, supports enough devices to cover what you own, and (if you don’t already have separate services set up) access to a password manager and VPN. Not sure if you need all that? Our guides on security suite features, password managers, and VPNs can help you decide. FAQ 1. What is the best antivirus software? Norton 360 Deluxe is our top pick for antivirus. It’s a very comprehensive security suite with a simple app that offers strong antivirus protection and protection against online threats, as well as a whole boatload of features—parental controls, storage for cloud backups, a password manager, VPN, and PC utilities. We like it for how extensive yet affordable the service is—you’ll be hard-pressed to find a comparable rival. 2. What is the best free antivirus software? If you’re reading this on a Windows machine, you already have it installed. Windows Security is a superb free antivirus option that covers all the basics, including ransomware protection and light parental controls—and it’s automatically enabled if no other antivirus software is installed on your PC. Its only downside? You’ll must tweak its settings to get the most of it, and also still sign up for other security services like a password manager for well-rounded online protection. 3. Is antivirus necessary in 2026? Unfortunately, yes. Viruses, malware, and other online threats have only increased and become more sophisticated over time. Spending time on the internet or attaching any external drives to your computer without antivirus software is like going into battle without a stitch of armor. 4. Is Windows 10/11’s built-in Microsoft Defender antivirus enough, or should you pay for more? While Windows Security (which includes Microsoft Defender) performs well, the best third-party antivirus software have even higher rates of detecting threats. The top antivirus apps also offer more control over settings, detailed logs of your PC’s activity, a more user-friendly interface, and additional features to strengthen your online security beyond just viruses and malware. So strictly speaking, a Windows PC doesn’t need third-party antivirus software, but you can benefit from more comprehensive online protection. (Macs also need antivirus software.) ...
