Norton 360 Deluxe Final
During the past few months, we have ranked, rated, and reviewed 40 premium antivirus suites from the biggest names in cybersecurity. We did this so you can confidently choose the best antivirus software to protect yourself and your family.

Right now, we think that Norton is the best antivirus software your money can buy. It regularly earns perfect or near-perfect scores from independent labs and has the least impact on system performance compared to rival products. Its products combine top-notch security with an array of excellent security features and, best of all, offer exceptional value for money.

Overall, Norton 360 Deluxe (currently at 70% off) is our pick for the best antivirus suite in 2020. It is competitively priced and comes with almost everything you could possibly ask for, such as a firewall, a fully integrated VPN, dark web monitoring, cloud backup storage (50GB), a password manager, and parental controls. You can cover up to 5 PCs, Macs, smartphones or tablets with this suite.

If you want full-on identity protection and don’t mind paying more, Norton 360 with LifeLock Select (currently at 35% off) gives those in the US a full range of identity protection features, more backup space (100GB), as well as all the above.

These days, it’s likely that a large part of your life is stored in your internet-enabled devices, mainly computers and smartphones. A study held by a reputable media company found that the average American devotes over 10 hours a day to screen time.

The so-called ‘digital freedom’ we enjoy comes at a cost.

Do you know the AV-Test – which is an independent security institute — detects over 350,000 new malware samples every single day? Every link clicked, email opened, purchase made, video streamed, file downloaded is an opportunity for hackers to break into your computer (and other devices) to compromise your data and privacy.

Even if you only visit trusted websites, avoid clicking dangerous links, and stay away from shady neighborhoods, experts say that you still need a reliable security software to protect your data and privacy.

It’s always better to be safe than sorry.

First, let’s see the security suites Kaspersky and ESET offer.

Now, let’s get into the details…

What’s Included in Kaspersky’s Antivirus Suites?

Offering different levels of protection at different price points is a common trend among cybersecurity companies.

Kaspersky’s line-up of security products starts with the barebones Kaspersky Free, which is only compatible with the Windows platform. The freeware offers protection against different types of malware threats (such as viruses, worms, ransomware, Trojans), but you won’t find many advanced protection-related features or utility tools incorporated into the product.

Next level up is another Windows-only suite, called Kaspersky Anti-Virus. Besides offering top-notch protection against all kinds of malware threats, it offers multi-layered ransomware protection, complete web-browsing protection, a vulnerability scanner (checks for outdated software and other exploitable vulnerabilities), and the Game Mode feature (minimizes notifications for uninterrupted user experience).

A single license of the suite provides a year of protection for a single PC, with the option to add more PCs at an additional cost. (We will cover the pricing information later in this guide.)

Another level up is the multi-platform compatible Kaspersky Internet Security. It includes everything found in the previous suite, plus a firewall utility (filters malicious network traffic and blocks attacks), a hardened web browser (helps protect your financial details when you shop/bank online), and a limited parental control module (blocks inappropriate content for kids and lets you to keep a check on their online activities).

Protection against webcam/microphone spying is also built into the product.

The suite is compatible with PCs, Macs, and smartphones and comes at different price points depending on the number of devices covered in the plan.

Kaspersky Total Security is the company’s high-end antivirus package, boasting almost all the advanced features and utilities you can expect to find in a mega-suite. It includes everything found in the “Internet Security” suite, plus a full-blown password management tool (stores all your passwords and other details in a secure vault), the Data Shredder utility (lets you delete your confidential files securely so no one can recover them), and an encryption tool (helps create digital vaults on your drive where you can store your important data).

A full-fledged parental control module is also included in the package, along with a useful back-up utility (automatically creates backup copies of your data).

Kaspersky recently introduced another high-end security package, called Kaspersky Security Cloud. It contains all the advanced features/tools jammed into the “Total Security” suite, plus it comes with “patented adaptive technology” which claims to adjust your security settings automatically and advises you based on your activities.

The package comes in two versions, Personal and Family. The only different between the two versions is that the Family edition lets you install protection on up to 20 PCs, Macs, and smartphones (in any combination) for $149.99 per year, while the Personal version costs more or less the same as Kaspersky Total Security, $89.99/year for 3 licenses and $99.99/year for 5 licenses.

Features Included in Kaspersky's Antivirus Suites

Note: All premium Kaspersky security suites are compatible with Windows, macOS, Android, and iOS platforms, apart from the entry-level Kaspersky Anti-Virus package.

What’s Included in ESET’s Antivirus Suites?

ESET offers separate products for different platforms, but some of its products are multi-platform compatible.

First, let’s see what ESET offers for the Windows platform.

ESET NOD32 Antivirus is the company’s entry-level package for the Windows users. It provides protection against almost all kinds of malware threats, but there are no premium security features or tools integrated into the package, other than the useful Silent Mode utility.

One level up is another Windows-only suite, called ESET Internet Security. It includes everything found in the entry-level suite, plus a two-way firewall, an email filter (blocks junk emails and phishing scams), a hardened web browser, an anti-theft module (helps find lost or stolen devices), and the Network Monitor utility (protects your Wi-Fi network against hackers and intruders).

Webcam protection is also built into the “Internet Security” suite.

Another level up is ESET Smart Security Premium – the company’s top-drawer offering for advanced PC protection. It includes everything that’s jammed into the “Internet Security” suite, plus a password management tool, the Secure Data module (an encryption utility that creates secure, virtual drives where you can keep your confidential files), and a full-blown parental control module.

If you have many devices in your household running on different platforms, you can consider ESET Multi-device Security Pack. A single license of the suite means you can install all ESET products (including those compatible with Mac and Linux) in any combination. But the downside is that there’s still a limit on the number of devices you can protect with the license.

So, if you have many devices in your household, Bitdefender Family Pack 2019 is an absolute bargain. It allows you to protect an unlimited number of PCs, Macs, and smartphones with the top-shelf Bitdefender Total Security 2019.

ESET Windows Antivirus Suites

Now, let’s see what ESET offers for macOS.

The company offers two specialized security suites for macOS, ESET Cyber Security and ESET Cyber Security Pro. The former provides comprehensive malware protection along with several additional security utilities, while the latter adds firewall and parental controls to its younger sibling.

Kaspersky vs. ESET: Which Software Offers Better Malware Protection?

Malware protection component (also called detection engine) is the heart of a security suite.

Malware can be categorized into two types: known malware and unknown malware (also called zero-day malware). The former type of malware can be detected using the traditional signature-based scanner, which usually works by matching suspect files against a database of known malware signatures. It’s the latter type of malware that poses a higher risk, it can’t be detected using signature-based scanning as it exploits a previously unknown vulnerability.

Most modern security programs employ heuristics scanning (checking for behavioral attributes of a file) to detect zero-day malware.

To see how good ESET and Kaspersky are in terms of malware detection, I will look at the most recent independent examinations conducted by AV-Test and AV-Comparatives – two well-known and most respected security laboratories in the antivirus landscape.

AV-Test’s most recent two-round evaluations were conducted in September and October 2018. The tests evaluated different participating products against both widespread and zero-day malware samples.

Kaspersky was one of the few products that received the perfect 6/6 rating from the AV-Test experts in the “Protection” category. It whipped all malware samples it was tested against during both months and only gave a single false positive case.

***False positive is counted when a security software wrongly detects a legitimate file/URL as malware-infected.

ESET, on the other hand, didn’t participate in the recent AV-Test examinations.

Austrian lab AV-Comparatives also conducts a range of exhausted tests to determine how effective a security product is against malware infections. The two main tests that give useful insights into the malware detection capability of a product are the Real-World Protection Test and Malware Protection Test.

The recent Real-World Protection Test report released by the lab includes combined results of five consecutive tests which were conducted in regular intervals, between July and November 2018.

Kaspersky was among one of the few products that were awarded the highest “ADVANCED+” award in the “real-world” study. It notched up impressive protection rate of 99.4% with no false positives.

ESET, on the other hand, didn’t perform as well as Kaspersky. Its average protection rate during the five-month period was slightly lower, at 98.9%, which means it had to settle for the second-best “ADVANCED” title in the test. It also gave a few false positives.

AV-Comparatives real-world protection test awards - July to November 2018

The Malware Protection Test is held after every few months by AV-Comparatives. The recent version of the test – which was held in September 2018 — evaluated 18 top security products against 11,890 malware test cases.

ESET’s performance was quite exceptional in this test; it received the highest “ADVANCED+” title because of its near-perfect 99.94% protection rate with very few false detections.

Kaspersky, on the other hand, could only get the second-best “ADVANCED” title, primarily because of its relatively lower 99.87% protection rate. It also returned 5 false positives during the test.

AV-Comparatives malware protection test awards - September 2018

Overall, it’s a tie in this category as both ESET and Kaspersky are in the same league when it comes to malware protection.

Winner: It’s a tie

Kaspersky vs. ESET: Which Software Puts Less Impact on System Performance?

Most modern antivirus products are extraordinarily light and do not put a significant burden on system performance (or system speed).

Let’s look at how Kaspersky and ESET fared in the recent independent performance tests.

In the “Performance” category of the AV-Test examination, the impact (or influence) of each participating product is measured in terms of system slowdown experienced while performing a set of standard computer operations, like launching popular websites, downloading & installing applications, copying files, and more.

Kaspersky got full marks from the AV-Test experts in the “Performance” category.

ESET, as mentioned earlier, didn’t take part in the recent AV-Test examinations.

The experts at AV-Comparatives also conduct an exhaustive test to measure the impact of various antivirus software on system performance. The most recent evaluation involved 17 software and was held in October 2018.

ESET was awarded the highest “ADVANCED+” award in the test, because of its exceptionally lower impact score of 1.7.

On the other hand, Kaspersky got the second-best “ADVANCED” award in the test, due to its slightly heavier impact score of 11.9.

AV-Comparatives performance test awards - October 2018

Overall, it can be said that neither Kaspersky nor ESET will slow down your system.

Winner: It’s a tie

Kaspersky vs. ESET: Which Software Offers Better User Experience?

It’s important for security programs to provide a good user interface.

First, let’s delve into the Kaspersky interface.

Kaspersky’s interface is neat and elegant, in colors of white and dark green.

The default view has a lot of information and links, but everything is so well-organized that it doesn’t look crowded at all. The green banner at the top is where you’ll find your current protection status.

Below the banner are six main modules, namely Scan, Database Update, SafeMoney, Privacy Protection, Parental Control, and Protection for all devices. Each module contains a set of related features and other options.

The name of the suite you have installed on your computer is shown in the title bar. The bottom bar links to Settings, Help, and more.

Now, let’s go over the ESET interface.

ESET’s interface is simple, bright and airy.

Along the left, you’ll find six categories, namely Home, Computer Scan, Update, Tools, Setup, and Help & Support.

Home is the default window, it shows your current protection status and has links to different advanced modules, like the Secure Data utility. If everything is safe and secure, you’ll a reassuring “You’re Protected” message with a green checkmark next to a creepy robot (okay, it’s not so creepy). The message quickly changes to “Attention Required” or “Security Alert” depending on the seriousness of the issue that needs to be addressed.

The other categories are pretty much self-explanatory.

The name of the product you’re subscribed to is displayed at the top. The bottom bar shows the number of days remaining in your subscription plan.

ESET User Interface as seen on Windows 10

Overall, Kaspersky’s interface is more intuitive and robust that ESET’s.

Winner: Kaspersky

Kaspersky vs. ESET: Which Software is More Popular Among Users?

Now, let’s see which software reigns in terms of popularity.

OPSWAT — which is a popular security company — regularly releases monthly reports on the market share of leading anti-malware vendors and products. Their most recent report was published in November 2018 and includes data collected from “tens of millions of data points and over 30,000 live endpoints.”

According to the report, Avast is currently dominating the market with an impressive 18.44% market share. McAfee and Malwarebytes are second and third with 12.58% and 12.23% share, respectively.

ESET is fifth on the list with 9.09% share, while Kaspersky (6.65%) claims the seventh position.

So it’s clear the ESET is more popular than Kaspersky in the antivirus landscape.

Winner: ESET

15 thoughts on “Kaspersky Vs ESET 2021 | The Ultimate Comparison [New Results]”

  1. Gerald R. Torres

    For me Eset is the best Antivirus because of its small footprint in my laptop. in addition, Eset delivers at the core protection from the advanced cyber threats.

        1. ESET offers a good level of protection, but there are better choices available. You can try Bitdefender. You can also save 50% on Bitdefender if you purchase through the links on this page 😉

          1. I had BitDefender, because it has been said it has the strongest anti-ransomware feature, narrowly edging out Kaspersky.

            But I had to kick BitDefender off my system, even though I already paid for it!

            Its the most insolent software I have ever installed – basically taking its own decisions without prompting you for your agreement. You can’t pause, defer or anything else with Bitdefender’s unruly actions. Example:
            I was copying a group of files, where one file was infected by adware. Not a particularly dangerous situation. Instead of giving notification and asking me what I want to do about it and when, it interrupted my multi-file copy process 5 times. The same for my alternative attempt to add those files to a compressed archive. Then it claimed “Your computer is infected”, which is a lie, because I’d have to actually run the file containing the adware to get an infection. The file just sitting on the drive does not an infection make.
            Since the file matters to me, I was planning to clean the file, rather than delete it.

            No other AV software has been this insolent. I still make the decisions on this computer. Last time I checked, I was the one who spent the $2000 to purchase it, not BitDefender. If I was just borrowing my PC from BitDefender, by all means, that would be different.

            Kaspersky, for example ASKS NICELY before doing anything. They have my respect.

            I also ask different questions to compare AV software:

            1) How much of a performance hit does it cause to my computer.
            2) How respectful of the computer’s owner is that software
            3) How good is it specifically against ransom ware???
            4) How good is it specifically against rootkits?

            Many internet comparisons don’t even talk about a single one of the points that are the very foundation of my decision…

          2. Hello there,

            Thanks for your detailed feedback.

            Bitdefender has a feature called Auto-Pilot which handles everything for you. For some people, it’s a great option as you don’t have to do anything; the software handles everything for you. But for some people, it may not work. And you can always disable it. It seems that you didn’t disable it.

            Anyways, independent tests confirm that Bitdefender offers superior anti-malware protection with very minimal impact on system performance.

  2. “How many more features it comes with” has never been a good criteria on which to base you antivirus purchase. For example, long time ago Norton used to be the best AV, until they started bundling their software with multiple “additional features”, mostly to compete with other similar antivirus software. The resulting “upgraded” product ended up causing computers to slow down and gamers (particularly but not only) to ultimately flee Symantec products. Also, don’t forget that an Antivirus IS a software on its own, which means IT can too be hacked (entry point for hackers) and the more “features” it comes with, the more potential entry points hackers can exploit. More is not always better. Personally I prefer ESET NOD32. Small footprint, lightweight and extremely powerful against malware/viruses. It’s the only thing it does but it does it very well without taking a performance hit on your computer.

    1. Thanks for your helpful comment.

      You are partly correct, but ESET doesn’t have a small footprint — at least not according to independent labs tests.

    2. I miss a bit the distinction against WHAT threat different AV packages are good against.
      My #1 need would be rock solid protection against Ransomware and Rootkits, followed by trojans.

      Everything else is just a minor annoyance, unless you’re oblivious and let them run unimpeded until they bring in something worse.
      In the early 90’s, I had to learn to clean my computer myself, without the benefit of AV software. It worked, but did eat up a lot of time…
      Like a different sort of computer game :p

      1. Most antivirus software offer excellent protection against all sorts of malware threats, including rootkits, phishing, trojans, etc.

      2. Runnomabur Pollard

        ESET has a much lighter footprint according to independent tests. Why are you always drawing some conclusions using the results from a few years ago? There must be some reasons behind!
        furthermore, ESET has taken part in AV-Test, AV-Comparatives AND Virus Bulletin (ALL THREE) as well as most of the other independent testing labs! How can you say that ESET didn’t take part in AV-Test? At least, ESET entered the test in late 2020, but I see that your blog was updated January 2021! How is that even possible?
        In fact, most of the cybersecurity fans will only love to hear about facts.
        Hope you update the blog completely if you are updating it, or else you are just misleading people to buy products that are actually not too good. According to a test done in late 2020, ESET and Kaspersky have FAR better protection than BitDefender. Hope you understand that and update your blog regularly. I really like the way you compare – it’s just not updated enough. Thanks!

  3. I bought Kaspersky & it won’t load. This happened after an update and the same behavior on two computers at the same time. This has been over a month with support. They have me do all kinds of things to my computer. In between my submitting reports, they take about 3-6 days to get back to me every time. They won’t refund my money.

    1. Sorry you had to go through this, Nancy. Kaspersky has had (and still has) a few issues. It has also lost trust in the eyes of the US due to its alleged involvement in the political stuff. Give Bitdefender a try if you are fed up with Kaspersky. Use the links on this page when purchasing Bitdefender to secure a discount for the first year. It also helps our work a little bit 🙂

  4. ESET has a much lighter footprint according to independent tests. Why are you always drawing some conclusions using the results from a few years ago? There must be some reasons behind!
