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.

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.

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.

Avira Antivirus for Endpoint This is Avira's main small business product. It takes all the core features you'd expect — antivirus, baseline network protection, web filtering — and extends them with file server protection and optimisation, along with application whitelisting and blacklisting.

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.

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. 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 Antivirus 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 security cloud software on federal government computers because of alleged ties between Kaspersky and the Russian government. 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 internet security products -- and perhaps use one of the antivirus software products mentioned here instead.

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 runs virus 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.
