Or a dedicated anti-ransomware layer of protection that only comes with the paid-for product could help catch one of the most dreaded infections and halt it in its tracks. For more on this, read our full piece on whether free antivirus is enough to protect you. Or just keep scrolling as we reveal today's best free antivirus software providers Paying for a premium service means you get more features like spam filters, parental controls, system scans and advanced firewalls.

It also means you avoid annoying pop-ups that try and tempt you to upgrade to the full version. In fact, these days you can get top quality protection absolutely free, with just about every single major vendor out there offering a free antivirus. Avira Free Antivirus is today's best free security download If you're determined to get free antivirus, we strongly suggest that you go for our pick of best security downloads - Avira Free Antivirus.

We've highlighted its long list of features below, together with information on how well it performs at independent testing labs. A very impressive freebie. That's pretty good for a freebie, and why we have no qualms at all in naming it as our 1 best free antivirus download. As well as the essential security smarts, we also love the clean, friendly interface and the fact it has a track record of throwing up minimal false positives.

In fact, the list of features reads more like a fully paid premium package. It throws in identity protection, a password manager, anti-scam protection to prevent phishing attempts, and even a PC cleaner to keep your system spick and span. If there's one thing we'd change then it's the tad overeager badgering - although popups and advertisements are very common to free products, and that doesn;t prevent us from wholeheartedly recommending Avira Free Antivirus.

Review and where to download: Avira Free Antivirus. Avast and AVG haven't yet fully merged, despite the former formally acquiring the latter in mid The newly combined company says the two free antivirus products will remain separate, although there's apparently a joint AV package on the way soon. Obviously, though, Avast now has a lot more data to work with, having expanded its effective userbase and, therefore, its threat detection network to a whopping million users.

The latest edition of Avast's free antivirus - now branded Avast One Essential - adds an automatic gaming mode to mute popups and reduce system load when you're firing up a processor-hungry game, which is very handy indeed, and the interface has been given a clean new overhaul. There's a password manager, too, which is an undeniably good addition to your security portfolio.

It scores well on AV-TEST's widespread malware benchmark and continues a clean sweep against 0-day attacks — presumably that expanded detection network is really helping.

Less impressive is the slight negative effect Avast has on software launch times, and its slightly popup-heavy attitude. Review and where to download: Avast Free Antivirus. Microsoft Defender formerly Windows Defender was generally seen as a bit of a joke in the not-too-distant past.

It performed terribly by most measures and was a good advert for why you should really pay for antivirus. But as we explain further up this article, Microsoft Defender has come on leaps and bounds and can now legitimately be mentioned in the same company as Bitdefender, Norton and Kaspersky.

As well as very solid virus protection, Defender has extra bits and bobs like a ransomware shield, webcam protection, privacy tools and even basic parental controls and cloud backup. And the best bit No need to download a thing, just find it in your menu and get protected straight away.

Read more and see how to use: Microsoft Defender review. The paid-for version of Kaspersky's Windows security software frequently tops charts of best virus prevention solutions and AV-TEST once again gave it full marks across the board in its latest round of testing.

As you would expect, Kaspersky Free is a scaled down version of the full program - a tool that we really like more on which below. The free version ditches additional features such as privacy protection and safe payment sandboxes to concentrate on powerful, no-frills and - most importantly - free protection for your PC. The result is a tremendously easy to use and navigate bit of software that does an effective job of keeping you protected from viruses.

Using the nuts and bolts real-world scanning engine of the paid-for suite, Kaspersky Free is fiendishly hard for viruses and trojan horses to break down. And we love that it doesn't constantly pester you with nudges to upgrade to the full version.

But, ironically, we will just for a moment, because Kasperksy Anti-Virus isn't expensive to buy and yet affords much better protection to your PC or PCs. Review and where to download: Kaspersky Free. Marketing itself as "business-grade security", Sophos Home does a little more than most free antivirus software, and actually seems better suited to families. You get standard virus protection and anti-malware protection, along with browser tools like anti-phishing and, most importantly, content control.

Combined with central management of up to 10 PCs, this means you can effectively lock down your kids' browsing options.

Although Sophos Home has always had desktop notifications, there was no premium version of the software for it to encourage an upgrade to. That changed in February with the launch of Sophos Home Premium. Review and where to download: Sophos Home.

Each entry in this list has been carefully chosen for its business features, such as remote installation and central management. The best business antivirus software will have enterprise-level protection against threats, but that doesn't mean they have to cost a lot of money, either.

The price per installation can sometimes be cheaper than even our recommended best antivirus packages. Avast Business Antivirus Pro An excellent business antivirus suite, giving you various tools such as virus protection, Firewall, email protection, anti-spam and the ability to sandbox applications for complete security.

Avast Business Antivirus Pro as opposed to the standard Avast Business Antivirus also includes Sharepoint and Exchange protection, as well as a number of tools for your servers. Bitdefender products are loved by the independent testing labs, highly rated for malware detection, removal, performance and usability. Most of the features work automatically — anti-malware, firewall, web advisor, URL filtering — but you can also customise the product to control user actions.

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.

There are well over of them, and you can export your settings to make setup on another PC quick and easy. We chose Avira as our free option because of the level of customization available. Whether you want to duck your head into the software's menus and start fiddling with knobs and dials is up to you, but if you do decide to tweak Avira's behavior, you'll find a modest tool chest of options.

One setting we highly recommend enabling is to search for rootkits before scanning. It will increase scan times, but rootkits are particularly nasty in how they dig their hooks deep in the OS, so it's better to err on the side of safety. You can also configure how aggressively Avira scans for zero-day threats through heuristic analysis, set to a medium detection level by default.

Cranking it up to high puts Avira in an extra cautious state but at the risk of reporting false positives. Putting it on low has the opposite effect, or you can turn off heuristic analysis altogether, an option we don't advise.

What you don't get with the free version of Avira is a Game Mode. And though Avira doesn't cost any money , you pay for it through the annoying ads. This is where BitDefender's free version has the advantage. In contrast, it doesn't use ads, nor does it nag users with pop-ups, and it pauses system scans when you're gaming.

The best antivirus will be reliable above all else, but the best antivirus for gaming will keep your gaming PC safe without interrupting your gaming sessions. It should also be light on system load, though that's not always an easy task. Generally, you can get away with just running Windows Defender, but it also requires a good dose of common sense.

Remember to only download games from trusted sites and avoid clicking random links. If you're dubious, it's worth spending a little on an antivirus solution for extra peace of mind.

There's no noticeable difference when it comes to the best antivirus', particularly if it's just ticking away in the background. Running a scan can be a different matter however, so we recommend doing so outside of your game time.
