May 07, · After checking for available updates for your Windows operating system, keep the automatic update turned on in order to download and install the important updates that can help protect your PC against new viruses or next-generation malware. Always remember to keep your OS up to date with the latest security available.
Your Windows PC needs protection against malware and free antivirus software may be enough. Here's the best antivirus protection for Windows 10 and what's worth paying extra for. Now that so many of us are working remotely and using personal devices for work projects, it's harder than ever to protect your personal information online. With so much increased time online, your security quiver needs plenty of arrows, including a secure VPN to protect your internet traffic, a password manager to keep track of login credentials and an end-to-end encrypted messaging app to stop others from spying on your communications.
And, if you're running Windows, that list should also include antivirus tools such as malware protection and antivirus software that monitors downloads and observes your system's activity for malicious software and suspicious behavior. An insidious program can easily wind up on your machine and that can lead to chaos. If you're looking for the best malware protection and antivirus software, here's the first thing you need to know: Microsoft Defender Antivirus -- the free internet security software and virus protection program that comes with Windows 10 -- does a decent job of protecting your PC and offering internet security.
Amazingly, Microsoft provided no built-in protection for Windows back in the days of Windows 98 and XP.
Using Microsoft Defender for threat detection should be your starting point for the best antivirus security on Windows and most people will find they don't need to go any further when it comes to nailing down an antivirus solution.
Stay current on the latest Microsoft news, plus reviews and advice on Windows PCs. However, keeping your personal data safe and guarding your privacy extends beyond virus protection, and that's where third-party antivirus software shines.
A full protection package can monitor your Windows operating system as well as MacOS, iOS and Android devices and include a password manager, secure online backup, identity theft protection, a VPN, parental control, webcam protection, protection against phishing and malicious websites and more -- all worthwhile security suite tools that can keep your data secure and guard your privacy.
To help you decide, I've put together a list of the best antivirus products for Windows 10, encompassing both free antivirus programs and subscription options. These picks of the best antivirus programs are a combination of recommendations from independent third-party labs AV-Test , AV-Comparatives and SE Labs , as well as our own hands-on testing.
This list is updated periodically. 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. 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.
Note that Microsoft changed the name of Windows Defender to Microsoft Defender and has expanded the service to other platforms. This antivirus program is built into Windows and it's turned on by default, so just let it do 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. 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 security 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 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 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 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 it's 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 not as well known to consumers because of its focus on enterprise security, Trend Micro 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. It earns high scores for usability and offers solid virus protection. The free 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's antivirus for Windows performs well for malware detection. 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 want to look at the company, specifically the reports at the end of last year that Avast allegedly collected user data with its browser plug-ins and antivirus software and then this year that it sold data it collected through its subsidiary company Jumpshot.
In response to the reports that his company gathered and sold the details of its customers' online activities, Avast's 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, he said that in January of this year, Avast terminated Jumpshot data collection and will wind down Jumpshot's operations because the data collection business is not 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. The CCleaner revelations, while concerning, were self-disclosed, which is important to building user trust.
We hope Avast's more privacy-friendly policies mean that there will be no further Jumpshot-style activities. In the meantime, we'd recommend using one of the many other solid choices in this realm listed above. Because the company has been in the news the past few years, let's talk about Kaspersky Lab -- specifically about the federal ban that blocks US government agencies from using Kaspersky products.
Based in Moscow, Kaspersky Lab has for years produced some of the best antivirus software for business antivirus needs and home customers. But in the US government prohibited Kaspersky software on federal government computers because of alleged ties between Kaspersky and the Russian government.
Notably, the ban does not apply to its consumer products. But, as with China-based Huawei , the question remains: If the federal government doesn't think the products are safe enough for its own devices, should consumers avoid them as well? In a statement sent to CNET, the company said, "Kaspersky Lab has no ties to any government, and the company has never, nor will ever, engage in cyber offensive activities.
Kaspersky Lab maintains that no public evidence of any wrongdoing has been presented by the US government, and that the US government's actions against Kaspersky Lab were unconstitutional. In Kaspersky's favor, it continues to earn top scores and awards for virus and malware detection and endpoint protection from independent testing labs.
And it's reasonably priced. In the end, even though no one has ever publicly produced a "smoking gun" linking the company to Russian intrigue, we think any of the options listed above are a safer bet. And, if you are a US government employee or work with the federal government, you'll want to steer clear of Kaspersky. Picking the best antivirus software for Windows means finding one that keeps your PC safe, doesn't take up a lot of system resources, is easy to use and stays out of the way till you need it.
Here's what to look for. Antivirus software scans for known viruses and malware, of course, and can offer real-time protection. And it watches for shady websites and suspicious links to keep you out of trouble. It can also offer ransomware protection and monitor unexpected behavior that may be a sign of new and not-yet-identified viruses and malware. You want antivirus software that can successfully identify these unknown online threats without flagging too many false positives.
Light on system resources. You don't want antivirus software that taxes your PC's resources. If after you install the program, websites open slowly, apps download or open sluggishly or file copies take longer than expected, you may want to try another service.
The good news is, all our picks offer a free trial to let you try out the antivirus program, so if your system feels sluggish after installation, you may want to keep looking.
Cost and discounts. Don't just pay the sticker price for antivirus protection. Before you buy, check for discounts on a company's website.
Another way to save: The prices we list above are for 10 devices -- if the company offered that package -- but you can trim your cost with antivirus packages if you need to cover just three or five devices.
You may also find discounts on an app's Amazon page. To be effective, antivirus software needs to monitor what's going on with your PC and check in with company servers about unusual behavior.
The companies say they anonymize this technical data as much as possible to protect your privacy. But if you want to know more, the security companies on our list post privacy policies on their websites, so read their privacy statements to learn what the companies do with the information you share. Protection for other platforms. Microsoft is by far the biggest target for viruses and malware.
While the Mac does come under attack via sideloaded apps, it's rare, and if you download apps only from the Mac and iOS app stores and keep your guard up when clicking links and download files, you should be OK without an antivirus app on Apple devices.
