Top rating antivirus software

Does the program offer useful additional tools? Some of our newer performance tests were done on a Lenovo ThinkPad T with a 2. To assess a program's impact on system speed on both Windows and macOS, we used our own custom tests, which measure how long a CPU takes to match 20, names and addresses on an OpenOffice or Excel spreadsheet.

The longer it took the laptop to finish either test, the heavier the performance impact. Each lab subjects the major antivirus brands' products to stress tests involving thousands of pieces of malware, including hundreds of previously unseen samples.

Kaspersky antivirus products have been banned from U. Because the company is Russian and antivirus software can peer deep into a PC, using Kaspersky software would create an unacceptable risk for persons and organizations involved in national security and critical infrastructure.

However, we still think Kaspersky software is perfectly safe for home users. We've seen no evidence to convince us otherwise. Kaspersky researchers are well respected throughout the antivirus industry, and the company has publicly exposed Russian cyberespionage campaigns as well as those from the United States and other countries around the world.

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.

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. Whether you choose to go free or upgrade, the software is really in favor with the independent testing labs at the moment, ranking towards the top of the pile in real-world malware tests and anti-phishing tasks.

You also benefit from a simple firewall, data breach scanning to warn you if your online accounts are breached, and apps for Windows, Mac, Android and iOS. So why bother paying for Avast One? You'd have to really want one of those specific add-ons to want to part with your cash, otherwise we'd suggest going for a more fully featured internet security suite or just sticking with the free Essential download.

We saw a lot more thought pieces coming out in suggesting that the time was at an end to pay for your antivirus software. And while we generally disagree with that notion, Microsoft Defender is probably the best argument in its favor. That's because if you're a Windows user, there's a perfectly capable virus protection already sitting within your operating system. Microsoft Defender is a solid product that gives capable mid-range protection - mostly without users ever even knowing it's there.

Defender has a dashboard, its own scan options and so on, but you'll never even see them unless you go looking. In the testing from independent lab AV-Comparatives, Defender ranked pretty much slap bang in the middle of the 17 tested providers.

That means it's better at protecting your PC than even some of paid-for software out there. Outside of pure virus protection, it features lots of bonus features such as multi-layered anti-ransomware, firewall, webcam and privacy protection, web filtering, parental controls and backup. So what's stopping you from forgetting the rest and simply getting Defender up and running?

Well, those features mentioned above are all pretty basic and aren't up the standard of those offered by most of the security suites above. And it probably goes without saying that Defender is only available on Windows PCs - forget protecting your Mac or smartphone - and some features only play nice if you use Edge as your browser. In truth, Avira is probably best known for its Avira Free antivirus option which is among the best out there - see further down this page , but its premium packages should not be sniffed at — especially when you consider the incredible price you can now pay for its Antivirus Pro package.

The interface is smart and the various features — including the free but limited to 1GB monthly VPN — are now better integrated within the UI overall. The caveat here is that the ratings of the antivirus engine from independent test labs are only middling at best — but the app does provide a decent enough level of protection. Upgrading to the Internet Security or Prime plan adds further features like a full password manager, and the Pro version of Software Updater which provides automatic updates for your apps , plus Prime gives you the unlimited usage version of the VPN and mobile app support.

A real bargain. McAfee takes an interesting approach with its security range, as all the offerings are variants of its core Total Protection product, with the main difference being more devices are supported at higher tiers. McAfee Total Protection Single Device is the entry-level antivirus product, and as the name suggests, it covers one device.

There are also a ton of features on offer, particularly for a baseline product, and even if not all of them are of the highest quality, you get a lot for your money.

That includes an intelligent firewall, an integrated TunnelBear -powered VPN with unlimited data, a quality spam filter, secure file vault, and some PC speed-up options. The main stumbling block here is that the antivirus engine itself is not the best out there — although some results from independent test labs come out better than others — but this has to be something of a concern.

Further up the Webroot range, SecureAnywhere Internet Security Plus expands coverage from Windows and Mac PCs to mobile devices, also providing a password manager courtesy of LastPass and covering up to five devices rather than three.

And at the top of the tree is Internet Security Complete which introduces an automatic backup tool with 25GB of secure cloud storage and additional online privacy features. SecureAnywhere AntiVirus gives you everything you need, really, although Internet Security Plus is our top pick for the most rounded package.

Sophos Home Premium covers up to an impressive 10 devices Windows and Mac computers. Sophos provides capable virus protection, and worked well in passing our own anti-ransomware tests.

For the antivirus software on offer — and given the 10 device ceiling — Sophos Home Premium could work out as a great value proposition for those who want to protect multiple computers. Just note that Sophos no longer offers a long-term free version to new users. You'll see on the website you can download it for free, but that's just a trial version rather than an all-singing all-dancing free antivirus package. We've tested all of the biggest names in internet security, we've found that the very best antivirus software in is Bitdefender.

It's a superb bit of software - from its entry-level Bitdefender Antivirus Plus and its cast-iron malware defenses, excellent threat detection and genuinely value-adding extra features, right up to its all-singing, all-dancing Total Security that adds an array of maintenance tools and can be used to protect your family's computers, tablets and phones.

An antivirus app sits on your device like a guard dog, watching over the entire system and sniffing out any intruders malware , or indeed anything suspicious. In short, it offers real-time defenses against viruses or other threats, which if detected are immediately dealt with, preventing them from carrying out their destructive payload. As well as this automated protection, you can run manual virus scans whenever you wish. Think of these as the fingerprints of malware, and if something is spotted coming onto your system that has a matching fingerprint, the antivirus leaps into action, quarantining the offender.

The obvious answer is staring you in the face Consult our rankings in this article, which is based on our expert knowledge and thorough, continually updated reviews of the top antivirus players. That said, obviously you also have to bear in mind your own particular needs.

Or at the other end of the scale, maybe you have a large family with a ton of devices to protect, and you need a package to cater for that.

Or maybe you want a VPN service as well as antivirus, so a bundled package will save you a lot of money on subscription fees. In short, our recommendations are here as firm guidance, but modify these appropriately based on your individual requirements. For more thoughts on this, check out our article exploring how to choose the best antivirus.

The good news is that the best antivirus products are getting cheaper and cheaper to purchase, and free products are getting more and more effective A good free antivirus — like the ones we recommend on this page below — is a perfectly reasonable option for protecting your PC, with Microsoft Defender now the best we've ever seen it. That said, premium antivirus programs offer extra features above and beyond the fundamentals. A robust system of parental controls could be a huge win for those with kids, for example.

Download Malwarebytes For Free Now. Sophos Home Free offers pretty good free anti-malware protection. It also includes some helpful web protections and covers up to 3 PCs all within its free antivirus package. In addition to multi-device protection and remote management, Sophos is also a decent choice for families because it has free parental controls.

Sophos offers pretty good antivirus scanning and remote management for up to 3 devices — which is pretty generous for a free antivirus. Users looking for coverage on up to 10 devices, advanced malware and ransomware protection, and advanced web safety tools should upgrade to Sophos Home Premium.

Download Sophos Free Now. There is no such thing as a truly free antivirus. Most antivirus companies limit the free version of their software to only offer basic protection. Windows Defender is not a bad antivirus — it even ranks a little bit better than some third-party free antiviruses. If you choose an antivirus program from a trustworthy company, then yes.

All of the brands on this list here are perfectly safe to use — the only difference between their free and paid versions is that the paid software includes additional features, like a VPN, a password manager, and parental controls, as well as better customer support options. Avira is my 1 pick for the best free antivirus in If you need a free antivirus, take a look at our list of the best free antiviruses in or just download Avira Free.

If you want the best protection for all of your devices, you need to pay for a premium antivirus program like Norton or Bitdefender. While there are literally billions of malware attacks reported annually, trojans and adware are consistently the most common types of malware found on Windows computers.

Trojans look like other files with extensions like. If you decide to uninstall your third-party antivirus, your PC will automatically ask you to reactivate the Windows Defender antivirus.
