Cybercriminals are becoming increasingly more sophisticated and high-profile attacks like the Columbia Pipeline hack are becoming more commonplace, which is concerning. Looking for free antivirus protection, malware protection or virus detection, willing to pay for an antivirus program that offers broad internet security coverage across all your devices, including from ransomware and phishing, or need to remove a computer virus or malware from your PC right now?
Here's where to start when looking for the best antivirus software for your needs. Honestly, if you practice safe computing -- you keep your software up to date, you use strong passwords with the help of a password manager , you steer clear of unexpected emails and you don't click suspicious links that may be phishing attempts -- you probably can avoid zero-day attacks and ransomware attacks. And with the free Microsoft Defender Antivirus software running on Windows 10, you have a malware protection safety net if you do let your guard down.
In fact, it is one of the best antivirus software. Note that Microsoft changed the name of Windows Defender to Microsoft Defender and has expanded the service to other platforms.
This free antivirus program is built into Windows and it's turned on by default, the antivirus engine does its thing, and this antivirus solution will cover the basics of internet security.
Microsoft pushes new updates frequently. Defender also lets you tune the level of protection you want, giving you control over blocking potentially unwanted apps and protecting folders and files from a ransomware attack.
Note that Windows 10 will automatically disable its own Windows Defender antivirus when you install third-party antivirus.
If you uninstall the third-party protection, Windows 10 will turn back on its own antivirus. Norton antivirus provides industry-leading security software for PC, Mac, and mobile devices. Note, we don't think antivirus protection is terribly useful outside the Windows realm. In addition to malware and virus protection for your computer and mobile device, this antivirus suite provides GB of backup to the cloud, safe-browsing tools, a secure VPN, password manager, parental controls and LifeLock identity theft protection and fraud alert.
While not all of those services are necessarily best in their respective class, getting them all in one package is a compelling option. If you'd like to take a step up in securing your PC without taxing your wallet, it's hard to beat Bitdefender's free antivirus software for Windows The Windows security software offers real-time monitoring for viruses, malware, spyware and ransomware protection.
Bitdefender Antivirus Free Edition is easy to set up and stays out of your way until you need it. And the protection this antivirus product offers is solid. Bitdefender antivirus software consistently earns top marks for its antivirus protection and usability from the respected AV-Test independent testing lab. The free antivirus version covers one Windows PC. Malwarebytes does protect your PC from a virus or malware attack, scoring reasonably well in recent independent testing for guarding against malware threats.
But that's not really what Malwarebytes is known for. If you find yourself in trouble, the go-to disinfectant for many is Malwarebytes. To get the antivirus company's free antivirus version, download this trial version , which "downgrades" to a no-fee on-demand cleaner with fewer features that detects and removes viruses and malware when you run an on-demand antivirus scan after 14 days.
In addition to the four antivirus apps we recommend above, a handful of other anti-malware tools are worth considering among the best antivirus protection if you find them at a better price or just prefer to use one over our picks above. It feels like McAfee Antivirus has been around forever, first on its own in the '80s, then as part of Intel starting in , and then again on its own when Intel spun it off in And McAfee Total Protection has been around forever because quarter after quarter it creates solid, modern antivirus software that protects your PC.
In recent evaluations by AV-Test, it had high scores on both protection and performance. Maybe this antivirus provider is not as well known to consumers because of its focus on enterprise security, Trend Micro antivirus quietly brings its business expertise to the home with its Trend Micro Maximum Security tools.
Trend Micro's software earns high marks from AV-Test -- consistently scoring well for detecting zero-day attacks and widespread viruses and malware. And Trend Micro does a good job of not taxing system resources. Free version? It earns high scores for usability and offers solid virus protection. The free antivirus version of Sophos Home gives you virus protection for three Windows PCs -- using the company's high-scoring anti-malware tool -- plus a day trial of the company's malware-removal tool.
Test after test, Avast Antivirus for Windows performs well for malware detection with options ranging from Avast free antivirus software to Avast Premium Security. And we've included its antivirus in our list of recommended security app options before. But Avast was in the news for several months for its non-antivirus business, so we looked at the company, specifically reports at the end of that Avast allegedly collected user data with its browser plug-ins and antivirus software and then sold data it collected through its Jumpshot subsidiary in early In response to the reports that his company gathered and sold the details of its customers' online activities, Avast CEO Ondrej Vlcek said in a statement that he understood that his company's actions raised questions of trust in his company.
To address that, Avast terminated Jumpshot data collection in January and closed its operations because the data collection business wasn't in line with Avast's privacy priorities. These newer reports follow another in from Avast that its internal network was breached , possibly to insert malware into its CCleaner software, similar to an earlier CCleaner hack that occurred prior to Avast's acquiring the Windows utility.
Avast is now saying the right things about taking its customers' privacy seriously , but it only came to that point after reacting to investigative reporting that revealed the Jumpshot practices. You can now get free antivirus protection that's as good as anything you pay for. So here are the best free antivirus programs based on their protection, system impact, ease of use and extra features. Kaspersky Security Cloud Free 2. Bitdefender Antivirus Free Edition 3.
Windows Defender Antivirus 4. Avast Free Antivirus 5. Kaspersky Security Cloud Free Antivirus may be the best free antivirus program we've ever seen. It has excellent malware protection, a decent set of extra functions and features, and a system-performance impact so small that our computer actually sped up after we installed the program. Bitdefender Antivirus Free Edition has been officially discontinued, and we're not sure how long Tom's Guide readers can still download it.
It's the best "set it and forget it" free antivirus option. It's now one of the best antivirus programs altogether. You don't have to install or download it — it's already on your PC. If you want an unlimited password manager or a hardened web browser, Avast Free Antivirus might be for you. Its malware protection is much better than it once was, although its performance impact is fairly heavy.
Avast's stepsister AVG has the same malware-detection engine, but lacks Avast's full slate of useful extra features. But it does have a file shredder and system optimizer. We have to mention one program that's not antivirus software, but which we recommend anyway: Malwarebytes Free.
While antivirus tries to stop malware from infecting your machine, Malwarebytes functions as the cleanup crew, sweeping out less-harmful adware or potentially unwanted programs that the antivirus software ignores. It works well alongside any antivirus program. Kaspersky doesn't talk much about its free antivirus product, and you might have a hard time finding the free Kaspersky software download page on the company's website.
That's too bad, because Kaspersky Security Cloud Free is the best free antivirus product we've ever tested. We've never seen such a combination of excellent protection and extra features in a free antivirus program. It's got a bright, comprehensible interface, a lot of customization potential and Kaspersky's unbeatable malware protection.
The program also lets you schedule scans, and its performance impact was so small that it actually sped up our test machine a bit. Kaspersky's useful extra features include a file shredder, an on-screen keyboard and an email scanner.
The password manager and VPN service are fairly limited, however, unless you pay. Read our full Kaspersky Security Cloud Free review. Bitdefender has officially discontinued Antivirus Free Edition, and it will be supported only until June 30, We still love it and you can still get it , but proceed at your own risk. Compared to premium paid antivirus programs that are big, heavy and loaded with extra bells and whistles, Bitdefender Antivirus Free Edition is like a '60's sports car, stripped to the essentials but still providing plenty of power.
Bitdefender Antivirus Free Edition offers nothing but the basics. There's no password manager, no gaming mode, no quick scans and no scan scheduling. You can manage the software from the program's System Tray icon, but you don't really need to interact with Bitdefender Antivirus Free Edition after its installation.
Yet Bitdefender Antivirus Free Edition has the excellent Bitdefender malware-detection engine, which sits just below Kaspersky and Norton in the lab-test rankings. It's the best free antivirus software if you want a security solution that you can set up and then forget about. It's also perfect if you need to protect the computer of an elderly relative but don't have time to manage antivirus software from afar.

While Windows Defender, aka Microsoft Defender Antivirus, doesn't quite beat Norton or Kaspersky in malware-protection lab tests, it comes out ahead of Avast, AVG and most other free antivirus products while operating almost entirely behind the scenes.
You won't be getting many extra features with Windows Defender itself, yet Windows 10 does have parental controls, a gaming mode and protections for its own Edge and Internet Explorer browsers. There's no built-in VPN, but you also won't be bothered by pop-ups trying to upsell you to paid antivirus software. As for a password manager, there's a stealth one built into the Microsoft Authenticator app for Android and iOS that syncs with the Edge browser, as long as you're signed into your Microsoft account on all devices.
We still recommend going for Kaspersky Security Cloud Free, which has even less of a system impact, better malware protection and more useful extras, but there's absolutely nothing wrong with using Windows Defender as your primary antivirus solution.
Read our full Windows Defender review. Avast Free Antivirus has the best assortment of extra goodies of any free antivirus program, including a hardened browser, a gaming mode, a Wi-Fi network scanner and a recently added ransomware shield. Unfortunately, the unlimited password manager has been discontinued. The program is also very customizable, letting you tweak its appearance and functions to suit your style.
It even offers limited access to Avast's VPN service. However, Avast Free Antivirus caused a pretty heavy system load in our testing and its scans took a long time. It also kept nagging us to upgrade to Avast's paid antivirus protection, and played bait-and-switch with features that looked like they were free but weren't. Most significant of all, the malware protection in Avast Free Antivirus is a peg down from Kaspersky's or Bitdefender's, whose free programs also bothered us less about paid upgrades and had lighter system loads.
Read our full Avast Free Antivirus review. AVG shares a decent, if unspectacular, malware-detection engine with its corporate sibling Avast while having a much lighter system-performance impact. While the latter is almost a free security suite with lots of bells and whistles, AVG AntiVirus Free is the quiet, neglected child that gets the hand-me-downs.
The good news is that AVG's wide range of customization options and its file shredder and system optimizer are still available, and its interface is open and easy to use. Worst of all, given its middling malware detection and dearth of extra features, there's no convincing reason to choose AVG AntiVirus Free over the built-in and overall better Microsoft Defender.
Malwarebytes Free, formerly called Malwarebytes Anti-Malware, is not antivirus software. Instead, it's a very useful malware-removal tool. What's the difference? Unlike antivirus software, Malwarebytes Free can't prevent a PC from being infected. But it does an excellent job of cleaning out malware that's already on your system, as well as removing legal adware and potentially unwanted programs that antivirus software often ignores.
Malwarebytes Free doesn't interfere with any antivirus software that's already installed, so it's perfectly safe to install it alongside one of our recommended brands. Just don't upgrade to the paid Malwarebytes Premium, true antivirus software that does poorly in lab tests and which will conflict with other AV programs. We recommend Malwarebytes Free as a complement to any of the best antivirus programs, free or paid. Read our full Malwarebytes Free review.
Before you buy antivirus protection, figure out what you need. If you have young children at home, then consider midrange antivirus products, most of which include parental controls. Do you want an all-encompassing security solution? Or are you a techie who understands and the risks of using the internet? Then a low-priced basic program might be all you need.
MORE: How to buy antivirus software. Once you've got your priorities figured out, then determine how many machines you'll need to protect. Most vendors offer single-device licenses for Windows PCs. But multi-device, multi-platform licenses for five, 10 or more computers and mobile devices are available in midrange and premium antivirus packages, covering Windows, macOS, Android, iOS and sometimes even Linux.
Some vendors offer plans that cover an unlimited number of devices. Gone are the days when you could walk into a store and pay a one-time fee for an antivirus product that came in a box off a shelf. All the vendors now sell their software licenses as yearly or multiyear subscriptions. The upside is that you'll always get the latest software, which you can download and install straight from the internet.
Many antivirus products are sold online for much less than their list prices. But each brand offers basic, midrange and premium configurations of features and pricing, with every step up adding more features. Think of autos at a dealership. You can get a base-model car that will get you from place to place just fine. For a few grand more, you can buy a car with satellite radio, but no heated side-view mirrors, alloy wheels or in-car Wi-Fi hotspot.
Or you can spend a lot more to get a loaded car with all the fixin's. Antivirus makers also hope you'll spring for extra options, whether you need them or not. The one thing you can't trade up to is a bigger engine: All the Windows antivirus products in a given brand's lineup will use the same malware-detection engine and provide the same level of essential protection.
The software will have essential malware protection and maybe a password manager or a two-way firewall. They generally add parental controls, some of which are very good, plus a few other features such as webcam protection.
They often include multi-device licenses and antivirus software for Mac and Android devices. At the top are the premium "security suites," which toss in all the extra security tools an antivirus brand can offer, such as password managers, VPN client software, backup software, online storage and even identity-protection services.
The password managers are often quite good, but the online storage can be paltry and the VPN services often don't give you unlimited data. That said, every free antivirus is going to include a few frustrating limitations. I tested and ranked each free antivirus listed here for malware detection, ease of use, and additional cybersecurity features. Read the full Norton review here.
Plus, Windows Defender consistently ranks below the top antivirus scanners in our independent lab testing. The free downloads on this list are from top-notch cybersecurity companies that are offering their premium antivirus protection for free. And some of the free programs on my list also include additional cybersecurity protections. Free antiviruses like Avira and TotalAV are pretty good, but their paid versions are way better — to begin with, they come with all of the internet security protections you need to stay as safe as possible online.
Together with a malware scanner, these tools are crucial to building a good online defense against hackers, scammers, and predators. Here are a few of them:. Avira Free Security for Windows is my favorite free Windows antivirus in — it has one of the best anti-malware engines on the market, includes more free features than any other competitor, and is really easy to use.
Paid programs like McAfee and Norton are equally effective at detecting malware, but their full disk scans will slow down your system much more than Avira will. The Safe Shopping browser extension for Firefox and Chrome is really good — it blocks suspicious phishing sites, web trackers, and unwanted advertisements.
The extension also automatically recommends links to better deals when shopping online. Download Avira Free Now. Another thing that makes Panda a good choice for Windows users is the Rescue Kit feature, which allows you to download a bootable version of Panda to a USB drive and then use the USB drive to clean an infected PC and get it up and running again. With lightweight malware scanning, an automatic gaming mode, a Rescue Kit, and a VPN, Panda is an excellent free internet security product.
Download Panda Free Now. It uses a huge blacklist to identify known phishing sites as well as an AI-powered phishing detection system to detect new threats. TotalAV is also the most intuitive free Windows antivirus on this list, with easy-to-use and easy-to-understand features and functions inside a minimalistic, well-designed dashboard. Kaspersky Security Cloud — Free is good at detecting and removing malware, and it also comes with plenty of extras — including:. All Kaspersky purchases include a day money-back guarantee.
Download Kaspersky Free Now. Malwarebytes Free is a good choice for users looking for a simple antivirus scanner that they can install and forget about.
Apart from the scanner, Malwarebytes Free also comes with a browser extension that protects against a wide range of threats, including malware, ads and trackers, scams, and PUPs.
