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.

Symantec Endpoint Protection Symantec's first benefit is the company's Insight file reputation technology, an effective way to detect and block even the very latest undiscovered threats. Other layers of protection include virus protection, behaviour monitoring, intrusion protection, a firewall, and the 'Power Eraser' to remove stubborn threats and repair your system.

Highlights included the breadth of telemetry, the strength of threat intelligence, and the advanced, automatic detection through machine learning, heuristics, and behavior monitoring. Independent security industry tests aim to evaluate the best antivirus and security products in an unbiased manner. However, Microsoft sees a wider and broader set of threats beyond what's tested in the evaluations highlighted in this article.

In an average month, Microsoft's security products identify over million new threats. In other words, the vastness of the malware landscape makes it difficult to evaluate the quality of protection against real world threats.

The capabilities within Microsoft Defender for Endpoint provide additional layers of protection that aren't factored into industry antivirus tests, and address some of the latest and most sophisticated threats. Isolating AV from the rest of Defender for Endpoint creates a partial picture of how Microsoft's security stack operates in the real world. We've proven that Microsoft Defender for Endpoint components catch samples that Microsoft Defender Antivirus missed in these industry tests.

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. 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 and it returns to glory as one of the best antivirus software. Plans come with one to five VPN licenses.

Trend Micro was founded in in the U. The company operates worldwide and has many partnerships in the tech industry.

Our top choice for malware scanning, Malwarebytes, is the best at removing malware on demand among any providers.

Malwarebytes was founded in Santa Clara, California, in and specializes in protecting home computers and mobile devices. The free version of Malwarebytes is limited but powerful. It doesn't have many advanced features and protections—it simply detects and removes malware. Malwarebytes does an excellent job of capturing, quarantining, and removing malware that is wreaking havoc in your system.

You can run a full or quick scan of the free version whenever needed, and it will create a report on your system. The premium version can be used as antivirus software. The free version runs on-demand, scanning for and removing malware, but should always be used in tandem with more comprehensive antivirus software.

While the software is available for multiple operating systems, premium offerings only work on Windows. A free trial is available for 14 days, but the free version remains on your computer to be used on-demand. Antivirus AV software is designed to detect, block, and remove malicious software on a computer or network.

AV software is an advised layer of any cybersecurity system, as it is often the first line of defense to protect the computer before the malicious software burrows too deep. It offers protection to a computer or network and helps prevent the virus or other malicious code from spreading to other devices. Hackers don't just make money by selling your personal information; they can use that data to buy things fraudulently, compromise your credit score, drain your bank account, and generally wreak havoc on your and your business's financial life.

Adding antivirus software to your computers is the least you can do to protect yourself. Windows continues to fight viruses designed to exploit vulnerabilities in the operating system, and until those vulnerabilities are patched, AV software is the first line of defense.

Windows 10 is the first version to include its own AV software built into the operating system. But if you want something that offers specific protections, the best option is to add a paid version that covers your needs. However, a long-standing misconception is that computers using Mac or Apple operating systems are immune to viruses and other malicious software attacks.

That was true two decades ago, but as Apple products became more popular, cybercriminals found value in designing viruses and malware for those systems. Also, increasing numbers of attacks can bypass the operating system and go directly for applications and web portals, putting every type of computer system at risk.

Other things you should consider doing to protect yourself against hacks are installing anti-malware software, using a VPN, improving your password, and setting up two-factor authentication on your devices.

While there are free options, you get better protection and more features with a paid subscription. Paid versions offer features such as VPN, password management, and parental controls. Free AV software has improved greatly over the years, and again, anyone using Windows 10 already has free AV software that works pretty well.

If all you want is software that detects malicious software, blocks it from doing damage, and scans your system, then free is good.
