What We Like
- Won industry awards from Virus Bulletin and Frost & Sullivan
- Both on-access and on-demand scans available
- Android app is just as functional as the desktop version
What We Don't Like
- iOS app doesn’t include antivirus protection
- Weak U.S. privacy policy
- Cluttered interface isn’t user-friendly
Bottom Line
If you’ve been keeping an eye on the Antivirus space for the past thirty years or so, you’ve probably heard of ESET. They’re a big name among tech geeks like us, and they’re pretty well-known among the public at large.
There’s good reason for this, too. Speaking practically, ESET is one of the most effective antivirus tools out there. They’ve won awards for how well their service performs — that’s right, they do have awards for antivirus solutions. If you’re looking to stay safer online, they’re definitely an option to consider.
But here’s the thing. Just because ESET performed admirably in lab tests, doesn’t mean it’s the right antivirus for you. Maybe it’s difficult to use or slows down your devices. That’s why we spent weeks testing every aspect of this antivirus. We’ll dig through all of its pros and cons to help you decide if it’s the right fit for your digital security needs.

How ESET Fares Against The Competition
The antivirus landscape is more crowded than ever, with new players constantly emerging. While ESET delivers solid malware detection, its interface complexity can put some users off. For the best of both worlds, consider one of these top-performing competitors:
ESET History
Before we get into it, here’s a short history lesson. ESET is a Slovakia-based company originally founded in 1992, though its very first code for the NOD software was developed as early as 1987 in then-Communist Czechoslovakia. It has some serious pedigree, not only as one of the very first antivirus companies, but also one of the longest existing.
ESET is not content to rest on its laurels, either. They continue to innovate. Recently, they introduced XDR (Extended Detection and Response) capabilities to their business solutions.1 We feel that this commitment to improving their services is valuable, especially in an always changing industry like digital security.

ESET Antivirus at a Glance
ESET has a lot going for it, so let’s go over its main points before getting into details. Note that for this review we tested both the basic Windows version (called NOD32) as well as the Mac version, Cyber Security Pro. We’ll assume that most readers are Windows users, so we used the Windows app as default, although there are also versions for Linux and Android. All in all, there are three packages you can get on Windows (bundled for Mac users): the basic NOD32 antivirus package, an intermediate plan called ESET Internet Security and ESET Smart Security Premium. This is a full suite of DIY cybersecurity apps, but more on that later.
NOD32, which we used for our tests, is a basic but sturdy product that scans computer systems, detecting and removing the following:
- Viruses
- Malware
- Spyware
- Ransomware

In the features list, it claims to “protect you from attacks,” which is ESET’s ransomware detection system. With ransomware attacks costing businesses over $50 billion per year, ransomware protection is a necessity, especially for businesses.2
ESET’s scans are both on-access, when the app is open, and on-demand, whenever you want, meaning you can scan unknown or suspicious-looking files in their File Explorer with a single click. We really like this kind of capability as it makes it very easy to protect yourself: if you’re ever browsing your file system and see a file that you don’t know where it came from, you can scan it right there and then. ESET will also alert you if files are acting suspiciously, prompting you to scan them.
The next package is ESET Internet Security, and it does all that NOD32 does, as well as:
- Stops hackers
- Helps secure your online shopping
- Makes the license usable across all of your devices
This mid-tier package hits the sweet spot for most users. The secure browser feature is particularly useful. It automatically detects when you’re entering payment information and creates an isolated browsing session that’s protected from keyloggers and screen capture malware. We also like the firewall which monitors network traffic for suspicious activities.
Last but not least is the ultimate package called ESET Smart Security Premium, which does all that NOD32 and Internet Security do, plus:
- Encrypts files (to learn more, read our guide to security personal data)
- Stores passwords
This last upgrade makes ESET an antivirus, encryption tool and password manager in one, which is a great deal and pretty much all we needed to secure our computer and phone against the dangers that lurk in the Internet. However, if you don’t want to pay for the upgrade, you can generate strong passwords for free on our site.
Tip: NOD32 is more than enough if all you’re worried about are viruses and malware. The ESET Internet Security and Smart Security Premium options are useful, but not vital.
Testing ESET Ourselves
We installed ESET NOD32 on our computer (well, a virtual machine running Windows 10 and rocking a five GB hard disk) and ran a scan using the recommended settings. Because of our tiny disk size, the scan finished in 34 minutes and, because it was a fresh install, it detected no viruses, malware or anything like that.

Of course, running a virus scan on an uninfected computer was no fun, so we infected it. We used five separate file types containing viruses. Though the temptation was there to open the files and let the nasties within run rampant, we resisted it and instead ran five separate scans with the dicey packages on our system. Below is a table with the results.
| File type | Percent of Antivirus Software That Detected It | Did ESET catch it? |
|---|---|---|
| .xlsx file | 34 percent | Detected |
| .exe file | 66 percent | Detected |
| .doc file | 36 percent | Detected |
| .xlsm | 35 percent | Undetected |
| .xls | 51 percent | Detected |
Well, four out of five ain’t bad. Really, though, it isn’t: we were surprised as most of the 40 antivirus services we’ve tested generally get three out of five or worse. The viruses we used are pretty new, so any that are detected means the scanner in question has a good, up-to-date database.
Caution: It’s never a good idea to click on a file you’re not sure about. If you’re not sure where a file came from, scan it first before opening it.
ESET’s Lab Tests
Independent testing confirms what we found in our hands-on evaluation. AV-TEST’s assessments show ESET’s history of consistently blocking all zero-day and widespread malware.3 ESET is clearly one of the best providers around when it comes to malware protection, and we’re more than happy to endorse its protection capabilities all around.
Installation and First Impressions
To combat those dangers, we needed to, of course, install the program first. The nice thing about ESET is that it has a 30-day free trial which only requires an email address to activate, so we decided to go with that plan first. This process was simple: we just went to ESET’s website, selected NOD32, the most basic package from the “for home” menu and clicked a download link. It was just that easy. The download of the installer took maybe a minute. Then the installation process, which included the full program, took another five and we were good to go.

The ESET app launches immediately after installation with its distinctive interface and dated robot mascot. While using it, we were never endlessly clicking through menus looking for a specific function or ability. The main scan button was right there in front of us, so we could get started right away. Before we get to that, though, we’ll quickly go over the interface. There are several tabs to the left of the client that controls pretty much everything that ESET can do. Here they are, top to bottom.
- Home: At the top is “home,” which is the main screen from where we could initiate a scan, upgrade to a paid plan or visit the ESET site.
- Computer Scan: This is where we could initiate scans from. We could set scan parameters, basically saying if we wanted to scan our whole disk or just a part of it. We could also select scan types, picking from a Smart Scan, which only scans files that have changed since the last scan, or an In-Depth Scan, which scans everything. There’s also a dropbox where we could put individual files to be scanned, which was pretty handy.
- Update: The button below Computer Scan let us update the client and its database of viruses. When it comes to antivirus software, these updates are really important, as viruses are always evolving.
- Tools: This is where the tools that tweak EST are found. These include the log files and activity reports, a task scheduler, and the SysInspector, which collected detailed information on our system’s security status. There was also a quarantine option that let us safely store files away from others, unable to infect them.
- Setup: Below that is setup, where we could enable and disable specific program features, such as the web access protection (which prevents you from accessing suspicious sites, on by default) or the anti-phishing system, which alerts you when you try to access a site associated with a known phishing scam.
- Support: Below that is a section from where you access support, but before we get to that, let’s first see how ESET looks on mobile.
Warning: Unless you’re an antivirus expert like us, we recommend you leave Setup and Tools alone or run the risk of viruses overrunning your computer.
Mobile Apps
ESET’s mobile strategy shows a clear divide between platforms. The Android app, ESET Mobile Security, delivers comprehensive protection with real-time scanning, anti-theft features, and app auditing. It ran a scan in about the same time as the desktop version, probably because the storage was about the same size.
However, the ESET app on iOS doesn’t actually have any antivirus software. It’s called ESET Secure Authentication and really that’s all it offers, two-factor authentication. We wish that ESET offered antivirus on iOS!
Pricing Information
Recently, ESET streamlined its pricing structure. The basic NOD32 plan now starts at $39.99 for one year on a single device — a significant drop from previous years. ESET works with a sliding system of pricing, meaning the upfront fee changes depending on the plan, duration and number of devices. More years (the maximum is three) and more devices (up to ten) means bigger savings, so it pays to spend some time looking through ESET’s pricing before making your final purchasing decision. Here’s a quick breakdown of what to expect, though.
| Number of Devices | One Year | Two Years | Three Years |
|---|---|---|---|
| One | $39.99 | $79.98 | $119.97 |
| Two | $44.99 | $89.98 | $134.97 |
| Three | $49.99 | $99.98 | $149.97 |
| Four | $54.99 | $109.98 | $164.97 |
| Five | $59.99 | $119.98 | $179.97 |
If you want to protect more than five devices, the Essential Home Security plan supports up to ten devices. It also adds ESET’s browsing, payment, and Wi-Fi protection features. Pricing starts at $49.99 per year for one device and goes up to $94.99 per year for ten devices.
Customer Support
ESET has great customer support. You can reach their support team through email and live chat 24/7. During our tests, they responded to live chat messages within two minutes. You can also call, but their phone line is more for corporate inquiries. Regardless, their responsive email and live chat support is plenty to quickly resolve any problems with their software.

However, ESET’s trump card is its excellent knowledge base, which is almost an encyclopedia of everything ESET. It’s easy to navigate, though you do need to know some basic information about your product, like its exact name and version number, to get the most out of it.
Privacy Policy
ESET has two privacy policies, one for the European Union, which is pretty good, and one for the United States, which isn’t as good. The E.U policy just restates that all customer data is protected by the GDPR, so nothing funny can happen to it. ESET only uses data it collects (your email address, location and phone number) to improve the experience for you and that’s pretty much it. The data is not shared with third parties.
While privacy legislation in the U.S. remains limited, 20 states now have comprehensive data privacy laws.4 For residents of these states, ESET must comply with stricter data handling requirements, including the right to access, delete, and opt-out of data sales. Customers outside of these states face weaker protections, with their data potentially being shared with third parties for marketing purposes.
That said, the data collected by ESET consists of your email address, phone number, IP address, and some device fingerprinting as well, as ESET collects your operating system and browser information. Honestly, we’re not comfortable with all the data that ESET collects on its paying customers like us, but there are very few competitors that aren’t guilty of these data-collection practices.

Conclusion
Overall, we love ESET antivirus, which is why it’s part of our best antivirus list. It’s a powerhouse of a solution and caught almost all the threats we laid before it. Plus, it was easy to use, to boot. Though for U.S-based customers, the privacy policy may give some pause and the pricing is a little confusing, ESET outshines the competition in almost every other aspect. We definitely recommend that anybody try out the ESET 30-day trial to see if the program is right for them.
