The core of the package is local scanning and real-time protection. On top of that, Kaspersky offers internet, email and browser security to protect against some of the most common threats employees face.

Who Should Use It: Businesses with fewer than 50 people that want proactive protection against common threats. Avast offers several different antivirus packages for business. Teams of under 10 can protect themselves with Small Office Protection, which includes ransomware, email and internet protection.

In addition to real-time protection across desktop, mobile and web, Bitdefender offers a suite of threat forecasts that can help you seal up any leaking holes before they become a problem. Before an attack, admins can monitor things like the number of unencrypted web pages employees visit. After an attack, Bitdefender gives you the tools to break down and understand why the attack happened and how to avoid it in the future.

After that, Emsisoft uses machine learning to detect zero-day malware and block it in real-time. That should cover most threats, but Emsisoft goes further. The software uses behavior analysis to detect potentially malicious apps, and it uses that analysis to detect things like ransomware before it can encrypt your data. Outside of protection, Emsisoft includes a centralized web dashboard for seeing the protection across your business.

From protecting a few devices in a small office to defending dozens of devices from large attacks, Malwarebytes has something for everyone. Who Should Use It: Malwarebytes offers a scalable platform that fits in the small office as well as it does in the sprawling enterprise. 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.

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.

Its top rival, Bitdefender Antivirus Free Edition, has been officially discontinued, although Tom's Guide readers can still download it with this link.

A merger between the biggest names in free antivirus, Avast and AVG, created a combined malware-detection engine that's much better than the sum of its parts.
