• Banking protection
• File backup (PC)

Background

ESET

Founded in 1987, ESET has been a stalwart in the antivirus industry, boasting a presence in over 200 countries and protecting more than 100 million users. With an unbroken streak of VB100 awards for malware detection since 2003, ESET has proven its reliability time and again. The company thrives on its legacy, continually pushing the envelope in cybersecurity innovation.

Kaspersky

Established in 1997 in Russia, Kaspersky serves a whopping 400 million users across 200 countries. With a portfolio that includes cutting-edge endpoint protection, they’re a go-to for 250,000 corporate clients. However, it’s worth noting that Kaspersky has been a subject of controversy due to alleged ties with the Russian government, which may be a concern for privacy-focused users.

Pricing & Compatibility

Price is an important factor to consider when searching for the right product for you. Many antivirus programs offer competitive pricing, with huge discounts on your first sign up.

Kaspersky offers a free, very basic, anti-virus program, but this still would protect you against the core common viruses and suspicious websites. The next tier up adds in computer performance, making sure it does not slow your computer down. The next tier, Kaspersky Internet Security, has the added features of webcam protection and an encrypted browser, making online banking safe and secure. Kaspersky Total Security has the added features of parental controls, password manager and a file backup feature. Finally, the all new Security Cloud program includes anti-ransomware, a VPN, mobile security, parental controls, and privacy tools.

ESET antivirus includes programs suitable for individual devices. This is great if you just want to protect the one device on Mac, Android, or Windows and you don’t need the software for anything else. ESET internet security and ESET smart security premium do not differ much. The Premium program comes with a password manager and an option to encrypt your photos.

Kaspersky offers a big discount on its Total Security software, with 70% off the normal price, making it $29.99. ESET also offers some discounts. The Smart Security Premium software comes in at $59.99 per year, but if you purchase it for two years it offers you a 25% discount.

ESET currently offers a 30-day free trial on all its software, which is great if you want to try before you buy.  Kaspersky also offers a 30-day money-back guarantee.

Both ESET Security Premium and Kaspersky Total Security work with all the major operating systems including Windows, Mac and Android devices.

In terms of price, both ESET and Kaspersky are fairly matched, however, ESET offers more with its specific protection plans, making it more favorable to the customer.

• How the antivirus affects system resources during both quick and full scans.
• How long the software takes to run a full scan.
• The efficacy of the antivirus software’s real-time scanning and malware removal tools.
• The effectiveness of the antivirus’ ability to detect, quarantine, and remove various malware samples and exploit classes.

Effectiveness against malware

Having an antivirus program is essential when wanting to protect your PC against malware. To see how each program performed, I conducted a number of tests.

The first test I performed checked for malware threats in real-time, rather than waiting until a scheduled scan. For the second test, I downloaded sample malware files from The European Institute for Computer Antivirus Research (EICAR). I turned off real-time detection on my computer and ran a full system scan and a quick scan to see how well the malware was detected and quarantined for each. The results are in the table below:

ESET blocked all EICAR sample malware files and the live samples. Kaspersky successfully identified all EICAR samples, and all were blocked. For the live samples, Kaspersky immediately deleted them after being unlocked and zipped.

To further the comparison, I took a look at the latest available data from the malware protection test (Real-Time Protection Test) from AV-Test which simulates real world scenarios.

In October 2021 both Kaspersky and ESET scored 100 percent against zero-day, which is brand new, never seen before malware, and widespread malware, giving them a clean sheet.

I also looked at AV-Comparatives latest Real-Time Protection test. In October 2021, Kaspersky was given a 99.9 percent score and ESET a 98.9 percent score, giving Kaspersky a slight edge.

AV Comparatives also runs a false alarm test, which checks how accurately a file or app is identified as safe or as a threat. The test results from October 2020 show Kaspersky and ESET once again match each other with zero false alarms. False alarms can be incredibly irritating for the user and can prevent systems operating as normal, so the lower the score the better.

In terms of protection against malware, there is not much difference between them both, with Kaspersky getting a slight edge in the second Real-Time Protection test, so Kaspersky is the winner here. Both products have proven that they are very effective security solutions.

Impact on PC Performance

When choosing the right antivirus program for you, it’s important to consider the impact the program will have on device performance.

To find out, I captured some data whilst running a full scan and a quick scan. The table below shows the data I captured and my findings.

Kaspersky took 227 minutes to complete a full scan, which is a good while longer than ESET, which only took 68 minutes. However, Kaspersky scanned many more items compared to ESET. In terms of the quick scan, ESET does not have a quick-scan setting; only full scans and customer advanced scans, meaning I can’t compare the two programs for quick scan speed and system impact.

I also recorded some data to see how my PC’s resources were affected by both antivirus programs, while the scan happened in the background.

Kaspersky had a slightly bigger impact on CPU utilization when there was no scan taking place at 46 percent, compared to ESET which was 32 percent. The other tests showed that ESET used fewer resources than Kaspersky, meaning the impact on my PC was slightly less than that of Kaspersky.

I then wanted to look at results from other independent tests to see if they had similar results. I used the test run by AV Comparatives that shows how each antivirus impacts PC performance during eight common tasks:

• Downloading files
• Browsing Websites
• File Copying: first and subsequent run
• Installing/uninstalling applications
• Archiving/unarchiving
• Launching applications: first and subsequent run

Each task is given a rating ranging between very fast and slow.

In the AV-Comparatives Performance Test from October 2021, Kaspersky came out with a very fast score for everything but the first run of an application, where it scored fast. ESET came out with a very fast score in everything but the first run of file copying which was fast.

When it comes to performance, both are very similar and had little impact on my PC performance, which was backed up by the independent test which puts them at a tie. ESET loses some points for not including a quick scan feature, while Kaspersky checks many more files than ESET’s full scan, although ESET’s scan did use less resources and was significantly faster. I’m happy to call this a tie.

Features

The added features the antivirus programs offer, in addition to the scanner itself, are important when choosing the right software. You want to get more for your money and enhance your security where possible. I’ve looked at what is included in each program to see what they both have to offer.

ESET

Sign Up and Installation

The sign-up and installation for both programs are very simple. ESET clearly outlines its price and gives you a strong comparison between all the different products they offer. At checkout, you can also add extra features such as encryption. There is also a toggle to opt for a monthly or yearly subscription with a breakdown of the price, which is really handy if you don’t want to be tied in long term.

Similar to ESET, Kaspersky makes it very easy to sign up. On clicking Buy Now, you are greeted with a pop-up window to upgrade to more devices. The next page is laid out simply, with an option to add on Kaspersky Expert Installation. The auto-renewal is automatically set to on, so if you do not wish to renew the following year, I suggest turning this off.

How easy is the interface to use?

Whether it’s your first time buying antivirus software or you’re an expert, the program should be easy to use.

Kaspersky’s home screen/dashboard will give you a green check to let you know that everything is running accordingly and that your device is protected. There are also common tools that you may need such as scan, database update, safe money, privacy protection, password manager, backup and restore and parental control. This makes it really easy to navigate to the right section. The design is fairly simple, with a light grey and green color scheme.

ESET’s interface has a slightly more modern design with the familiar ESET robot graphic. On opening, the green bar on your dashboard will be green, telling you your PC is protected. The bar will then turn yellow if it needs your attention and then red if it detects a threat on your device. You can easily navigate to computer scan, tools and setup on the left toolbar. You will also be able to participate in ESET’s customer experience program and offer feedback via the app.

Customer Support

Having reliable customer support is important when investing in any antivirus software. ESET does not provide 24-hour support and only answers queries from 6 am to 5 pm for US customers. You will be able to reach them through phone, online ticket submission, and email. Like most antivirus programs, there are a lot of support materials on ESET’s website including videos, troubleshooting, FAQ’s and an extensive encyclopedia of threats that you may face.

Kaspersky technicians are available to call between the hours of 7am and 1am, seven days a week. You can also reach customer support by email or online chat and receive a reply promptly. Extensive videos, FAQs and other useful information can be found on its website.

Antivirus testing: Our Methodology

I use a precise antivirus testing methodology that draws on various high-quality resources and datasets–as well as tests performed by our skilled in-house AV reviewers. I use this scientific method to identify important antivirus benchmarks, including:

• How the antivirus affects system resources during both quick and full scans.
• How long the software takes to run a full scan.
• The efficacy of the antivirus software’s real-time scanning and malware removal tools.
• The effectiveness of the antivirus’ ability to detect, quarantine, and remove various malware samples and exploit classes.

Our in-house tests aim to provide information about how each AV behaves in the real world on consumer devices, to give you an idea of what to expect in practice when it comes to the AV’s consumption of system resources and its ability to keep your device safe against threats in the wild. 

We then double down by analyzing and drawing on data from various industry-leading, professional third-party antivirus testing laboratories. This data gives us precise insights into the AV’s ability to identify and remove a wide cross-section of exploit samples, including viruses, worms, spyware, trojans, bots, and even ransomware. 

To ensure the data is sound we only stick to the following, highly regarded antivirus testing authorities:

• AV Test
• AV Comparatives
• MRG Effitas
• SE Labs

Leveraging these laboratories’ results allows us to back up our findings and provide users with an unbiased breakdown of each AV’s ability to protect devices against real-world threats.

Conclusion

If you skimmed past the part at the beginning of this article where I revealed the winner, here’s a refresher: ESET is a better choice than Kaspersky. Not only is ESET lighter on the data it collects from its users than Kaspersky, but it is also less resource-heavy on system resources.

ESET has a great range of pricing plans available and several helpful features, such as a file shredder and secure data encryption to protect your files from hackers looking to steal your data. ESET offers a good range of customer support options and a user interface that’s clean and easy to use.
