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 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, check in with company servers about unusual behavior and should provide sound banking protection.
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 side-loaded 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.

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. 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.
This makes them more suitable for power users, those who want a bit of extra security and anyone who needs their system to run as smoothly as possible. 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. It's the best antivirus software you can buy today. Click here if you're in the U. Bitdefender offers the best value in antivirus software Bitdefender Antivirus Plus combines great malware protection with an assortment of useful features and an easy-to-use interface, all at a very affordable price.
Norton packs in everything but the kitchen sink Norton's antivirus products offer a password manager, unlimited VPN data, identity theft protection, parental controls and even online storage. If you're willing to pay full freight, you'll get almost every kind of digital security you could ever need.
Kaspersky Total Security 2. Bitdefender Antivirus Plus 3. Norton Deluxe 4. McAfee Internet Security 5.
Trend Micro Maximum Security 6. Sophos Home Premium. Our top choice is Kaspersky Total Security, which delivers excellent malware protection, a full complement of extra features and an easy-to-use interface.
Right behind that are the entry-level Bitdefender Antivirus Plus, the best bargain in antivirus software, and Norton Deluxe, which offers a ton of extra features, including unlimited VPN service and LifeLock identity protection. Any of these three would serve you well, but the ideal choice depends on your circumstances. See our section on how to choose the best antivirus software below, or our stand-alone antivirus buying guide. Both offered excellent protection without system slowdowns, but Kaspersky's free program lets you schedule scans, adds a ton of useful extras and had the smallest system impact we've ever seen.
Kaspersky's Windows products have excellent malware-detection scores and a light-to-moderate system-performance impact, the two most important criteria in our rankings. But it's beaten by Bitdefender Antivirus Plus, which has even more features. It has a secure browser, anti-theft protection for laptops, webcam protection and a limited-use VPN client that kicks in when you connect to an open Wi-Fi network.
We think it's the best antivirus software you can buy today. Read our full Kaspersky Total Security review. The best antivirus software you can buy Kaspersky offers excellent malware protection, lots of useful extra features and a light system impact with an easy-to-use interface.
Bitdefender Antivirus Plus is our top choice among entry-level antivirus products. It has very good, if not perfect, malware-detection scores. Its active scans don't add much to the background system impact, but that background load is a bit heavy. It also offers the most value, with an unlimited password manager, a secure browser with a virtual keyboard, a Wi-Fi network scanner, a file shredder, protection against encrypting ransomware and Bitdefender's new web-privacy software -- features often found only with pricier antivirus packages.
The midrange Bitdefender Internet Security adds parental controls, webcam protection and a two-way firewall, while Bitdefender Total Security tops off the lineup with an anti-theft feature for laptops, a system optimizer and licenses for Bitdefender Antivirus for Mac and Bitdefender Mobile Security for Android.
Read our full Bitdefender Antivirus Plus review. All of Norton's antivirus products offer excellent malware protection, and the once-heavy system-performance load is much lighter. The number of extra features each program has varies, but the sweet spot in the lineup is Norton Deluxe.
It includes a password manager that works on all major platforms, unlimited VPN service, dark-web personal-data monitoring, parental controls and up to 50GB of online storage space.
Two other offerings, Norton Premium and Norton Platinum, give you more online storage and expand the antivirus and VPN coverage to 10 and 20 devices, respectively. If you want full-on identity protection, Norton offers three bundles with varying degrees of LifeLock service and even more online storage. Their subscription prices run well into the triple digits, but still cost less than if you were to buy the identity protection, password manager, cloud-backup storage and antivirus software separately.
Unlike some of the other best antivirus software makers, Norton doesn't offer a file shredder, file encryption or secure web browser with any of its products. Yet every other digital-protection service you could possibly ask for is included with at least some of its bundles. Read our full Norton Deluxe review. McAfee's malware detection has improved greatly in the past couple of years, but it's still not quite top-of-the-line.
To get parental controls or one of the best password managers in the business, you'll have to spring for McAfee Total Protection or its sibling McAfee LiveSafe, which comes pre-installed on many new PCs.
The multi-device licenses of those two security suites also come with an identity-protection service. But none of the McAfee products have a secure browser or webcam protection, which you often get with other premium antivirus programs.
Read our full McAfee Internet Security review. Trend Micro offers very good protection, but its malware-detection engine creates a heavy system load during scans and returns a fair number of false-positive results. Parental controls, a system optimizer and a file shredder are bundled into the mid-range Trend Micro Internet Security. Trend Micro Maximum Security adds a password manager, a secure browser and file encryption, while the new Trend Micro Premium Security adds a VPN and dark-web monitoring of personal data.
However, none of Trend Micro's programs include a two-way firewall or webcam protection, standard with other brands' midrange offerings. Nor does the premium product have the cloud storage or backup software that some of the best antivirus brands add as enticements to their flagship packages. Read our full Trend Micro Maximum Security review. ESET is one of the biggest antivirus names in Europe, with a very small system-performance load and fast scans. Its malware-detection rate used to be kind of meh, but has improved markedly in recent lab tests.
However, there's no VPN client, backup software or file shredder. ESET's pricing is per device, which is optimal for users who might have more than a few devices to protect.
But if your device count gets into double digits, ESET's costs can add up. Sophos Home Premium does its job economically, offering reasonable protection from malware at an affordable price. Because it's spun off from Sophos' enterprise software for business clients, Sophos Home Premium lacks many of the bells and whistles other security suites offer, such as a password manager, identity theft protection service or VPN service.
What Sophos Home Premium does have is the essentials: ransomware rollbacks, webcam defenses and protection against keyloggers, malicious websites and boot-sector and fileless malware. It also has a web-filter system for parents and an online management console from which you can tweak most of the settings.
Some people might demand more from an antivirus suite, but anyone who would rather buy only what they need will appreciate Sophos Home Premium's just-the-basics approach. Read our full Sophos Home Premium review.
A good paid antivirus suite is a digital-protection jackknife, often bundling in parental controls, identity theft protection, a password manager, backup software, cloud storage, a firewall, a system optimizer and software for Mac, Android and iOS as well as Windows. But what if you just want Windows antivirus software without all of those pricey extras?
And what if you can't afford to pay for antivirus software? One of the best free antivirus programs might be exactly what you need. Free antivirus software used to be a step down from the paid software and involved trade-offs.
The protection wasn't as good and you'd either have to put up with ads filling your screen or with constant nags to upgrade to a paid program. That's all changed. One of the best antivirus makers, Kaspersky, offers a free version with the same excellent malware protections as its paid offerings. Its top rival, Bitdefender Antivirus Free Edition, has been officially discontinued, although Tom's Guide readers can still download it with this link. 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.
Paid versions, however, will offer protections on web browsing, protect identity, or offer VPN services, as well as password managers and parental control across multiple devices and operating systems. These are more essential now, as more people are working remotely or using a single device for work and personal computing. Viruses are designed to replicate and spread, while malware is a catchall name for all types of malicious code aimed at damaging a computer or network. All viruses are malware, but not all malware is a virus.
AV software identifies threats through signature detections based on what is already known in the signature database. This is why AV software needs to be updated regularly. Antimalware software detects more sophisticated malware attacks.
The two types of defense software complement each other, and some AV software has antimalware built-in, but the two are different, and protection against both is necessary for true protection. There are hundreds of antivirus software solutions available. We investigated 20 popular solutions often considered the software of choice by cybersecurity experts. Of critical importance was the ease of use with all providers, making it something every consumer could navigate and use.
We then considered whether or not the provider had offerings beyond antivirus software. This included malware, ransomware protection, and multiple device protections.
Those that had a free version or trial were given preference. We gave particular importance to platforms that were easy to use and integrate. Pew Research Center. Your Privacy Rights.
