With both ESET and Avast scoring well in lab tests it’s hard to separate the two on tests alone. However, with Avast recently being reported to be selling user data I feel much happier trusting ESET to guard my privacy and security online.

Background

Avast is based in the Czech Republic, with its headquarters in Prague. The company is an established name in multinational cybersecurity software. It researches and develops computer security software as well as machine learning and artificial intelligence programs. There has been some recent controversy around Avast collecting user data and selling it through one of its subsidiaries, not what you would expect from a program designed to protect you online.

In 2016, Avast acquired antivirus company AVG. Over the last few years, Avast and AVG have combined the backend of their products, their detection methods, behavior blocking and cloud, to offer the same level of protection with different packages and interfaces. In August 2021, Norton announced that it would be acquiring Avast antivirus. As of the time of writing, Avast and Norton products remain separate. However, in the future, Avast and Norton’s detection capabilities could be combined to create a much more powerful security suite, as they are both market leaders. Norton also acquired antivirus company Avira in July 2020.

Also based in Eastern Europe, ESET was founded in Bratislava, Slovakia. ESET has been around since 1992 and the company has won many awards for their products. ESET has a large range of antivirus and computer security programs in its inventory, all of which have been highly lauded by security market critics.

Pricing & Compatibility

At the time of writing ESET offers a free basic version of its software plus three paid product tiers:

As the tables above show, even the cheapest version of Avast is more expensive than the top tier product in the ESET line up.

Avast offers a 30-day free trial on many of its products, including Avast Premium security. ESET offers a 30-day money-back guarantee if you are not satisfied with the product.

I have taken advantage of both these offers in the past when reviewing Avast and ESET products and I can confirm both companies do honor their money back policies should you ask them to cancel the subscription within the stated time period.

It’s worth noting that Avast’s multi-device option costs $89.99 (GBP £66.27) for up to 10 devices. This is a good option for busy households with lots of devices to cover. By comparison, the mid-range offer from ESET can cover five devices for the same price ($89.99) but costs $139.99 (GBP £102.75) to cover 10 devices.

Both ESET and Avast offer compatibility with Windows PCs, Android and iOS devices, and macOS.

Effectiveness against malware

To test the effectiveness of both ESET and Avast antivirus products against malware, I installed both products on my own PC and ran malware tests. The first test I performed was a real-time test that pro-actively looks for malware threats in the background while you are using the PC without waiting for a scan to be run manually or for the scheduled scan time.

For the second test, I turned off real-time protection and used multiple sample malware test files from EICAR (The European Institute for Computer Antivirus Research) on the machine. These test files simulate viruses in different forms and from both secure and insecure connections to see how antiviruses react.

I also tested out both the quick scan option if available, and the full scan to see what differences there were. Finally, in addition to my own research, I took a look at the test results from the leading independent antivirus test lab AV-Comparatives. Here are the results.

The table below shows the results of both antivirus products when tested with four different Eicar samples, plus three live samples that were tested contained adware and trojans.

ESET Successfully detected and deleted all files in real-time and blocked all four Eicar samples.

Avast allowed the Eicar samples when downloaded over HTTPS, but blocked them on HTTP. Avast also deleted all live samples.

Avast Threat secured

eset Threat removed

eset Full Virus Scan

ESET does not have a quick scan option, which would not scan the full system but just look at the most common areas targeted by malware on a device, so this could not be tested.

eset Computer scan completed

Avast smart scan

I was able to test the quick scan feature with Avast, called Smart Scan and it found no threats, compared to the full scan which found all threats (EICAR and live samples).

AV-Comparatives’ latest round of its Real-World Protection Test took place in October 2021. Both companies’ antivirus software scored well in the testing with Avast performing better in online detection and protection rates, while ESET scored better for offline protection. ESET recorded zero false positives compared to two false positives recorded by Avast. False positives occur when the antivirus incorrectly flags a non-malware file or process as malware.

The total online protection rates make Avast one of the top performers in the October 2021 round of testing, while ESET ranked middle compared to other leading antivirus brands. ESET was compromised 1.1 percent of the time while Avast was compromised 0.1 percent of the time.

The false positives test shows ESET as the joint top performer of all antivirus software tested in October 2021, with Avast close behind.

False positives are an important consideration when choosing an antivirus software because false results cause alarm and hinder how well users can use their machines. If apps or other files are wrongly labeled as malware it can affect productivity.

Impact on PC performance

A major factor most users (including me) care about is the impact the antivirus software has on PC speed and performance. To compare the impact of both ESET and Avast, I looked at some data while the software was running on my PC.

The impact on PC resources without running a scan is identical for CPU utilization for both programs, with Avast using more control memory and control disk utilization.

When it comes to impact when running a full scan ESET utilizes more CPU than Avast with 68 percent to 42 percent.

Memory utilization is closer with just a 3 percent difference between the two programs. ESET scores 70 percent while Avast uses 73 percent. ESET takes slightly longer than Avast to complete a full scan, completing the task in 68 minutes compared to 60 minutes for Avast.

The AV-Comparatives Performance Test measures the impact of the antivirus on speed and PC performance during a number of tasks. This includes:

  • File copying
  • Archiving / unarchiving
  • Installing / uninstalling applications
  • Launching applications
  • Downloading files
  • Browsing websites

The results of the test conducted in October 2021 show both ESET and Avast scored top marks in five of the six categories ranked as “very fast”. Only the first run of file copying for ESET and first run of launching applications for Avast failed to score top marks, but even these were ranked as fast.

When it comes to performance, my tests and the independent lab results show there is no clear winner between the two antivirus products. I also found similar results with my own tests, and using the PC to carry out tasks while a full scan was in progress. Both programs felt light on system impact. I was able to perform a number of tasks including browsing the web and launching apps while an antivirus scan was running in the background.

Many of the additional features can be found in both antivirus products including firewalls, password managers, and network security scanners, but there are also quite a few unique tools for each brand. It’s also worth mentioning that ESET offers more additional features than Avast. One other thing to note is that Avast requires you to download separate software to block spam and phishing emails, which is slightly annoying although it is free.

Which you find most useful depends on your personal needs. I will take a look at some of the standout benefits of each:

ESET

Gamer mode – ESET’s Gamer mode is a handy feature which can identify when other software programs are running in full-screen mode, suggesting that the PC is being used for gaming or watching a movie.  In this mode ESET minimizes interruptions and maximizes PC performance.

Anti-Theft (Windows) – This feature helps you track and locate your laptop in case it goes missing as a result of a loss or theft, but it is only currently available on Windows devices.

UEFI Scanner – Many antivirus products do not reach the motherboard’s UEFI,  (Unified Extensible Firmware Interface), a program that manages the PC boot up process. ESET scores extra points here because it is designed to detect any changes to the UEFI and can warn the user and pause the boot up process.

Parental Control – ESET includes a parental control feature so you can monitor and manage access to the internet and restrict certain content from children. This saves extra expense buying standalone parental control. Avast does not include free parental control in its offering.

Avast

Scan for Wi-Fi security weaknesses – Find intruders and security weaknesses in your network such as a weak router password. This tool also checks both home and public wi-fi for strangers piggybacking on your network and fixes any issues.

Safely run suspicious apps in Sandbox – Sandbox any app to test if it’s safe before running it on your computer. This will contain any malicious apps before they wreak havoc on your PC.

Permanently shred sensitive files – Securely delete files to ensure that no one recovers them. This works by overwriting files with meaningless data multiple times before deleting them so they can’t be recovered.Avast premium data shredder

Automatically update apps – Reduces security risks by keeping your other apps up-to-date without any gaps in between that leave them vulnerable to hackers or other security threats.Avast premium software updater

Avast SecureLine VPNA VPN offers good additional security tool to encrypt your internet connection for safe and private browsing.

Sign up & Installation

Signing up for Avast was straightforward with a simple billing form that asks for just a few details. Downloading the installation file took just a few minutes to complete and running the installation and performing a first scan took about 15 minutes, but I was able to minimize the scan window and keep working on my PC with no interruptions.

Avast Ultimate payment

ESET only require basic information such as your name and address and your card payment details during sign up.

The Windows installer file took less than a minute to download and then I was able to start the installation process. Once I reached the app interface, I also needed to update the product to enable real-time malware and threat protection. This seemed to take quite a while and I left it to update in the background for around 10 minutes.

How easy is the interface to use?

ESET has a fresh interface with a clear layout. The home screen features a banner that tells you the status of the system. A green banner lets you know everything is safe and secure, while if a scan should find issues a yellow bar will display alerting you to take a look. This status bar will turn red if the system is under attack.

The menu has a simple layout with main categories listed along the left side of the window making it easy to access the most important settings.ESET Nod32 interface

Avast uses a minimal design that looks really nice and clear. The main screen lets you run a smart scan for weak passwords, vulnerable software, networks, and browser add-ons, alongside a virus scan. Avast Premium dashboard

Other shortcuts marked with clear icons make it quick and easier to navigate to pages on Performance, Privacy, and Protection.Avast premium protection

Customer Support

Avast offers Premium Tech Support via phone that will help you solve any problem at any time by remotely accessing your PC, but it’s not included with your subscription. It comes with quite a hefty cost of $79.99 (GBP £58.71) for a one-off simple fix, $119.00 (GBP £87.34) for a complex fix, and $199.00 (GBP £146.06) for unlimited calls for a year. There’s also a FAQ and an online academy where you can learn about online threats.Avast customer support

ESET provides a help section to access all support documentation or request further help from customer support.  This includes email support, live chat, a knowledge base and user guides. There’s also a FAQ and help with installation and setup if required.ESET customer support page

Overall ESET seems to offer more options for support. The live chat option is easy to find and the quickest and most direct way to get help with a problem at no cost.

Antivirus testing – our methodology

At Comparitech, we use a scientific antivirus testing methodology that combines in-house tests with the results of leading antivirus testing laboratories. This method allows us to confidently review and recommend antivirus programs based on important real-world benchmarks. Below, are the important criteria we consider:

  • How does the antivirus affect system resources during both quick and full scans?
  • How long does the software take to run a full scan?
  • How effective are the AV’s real-time scanning and malware removal tools?
  • How good is the antivirus at detecting and removing a cross-section of exploits?

The tests performed in-house by myself and our review team and are designed to give readers a precise understanding of how an antivirus will perform when installed on their device. This gives you an idea of the program’s setup process, its ease of use, its design and interface, and how easy it is to use for protecting various devices.

We then leverage the data from various leading and respected antivirus testing laboratories, find out exactly how effective each antivirus is at identifying and dealing with highly malicious and prevalent malware samples, including some of the most recent exploits circulating in the wild. 

To ensure the data we use is reliable, we stick to using results from highly trusted antivirus testing authorities:

By sticking to the most recent test results by these independent laboratories, we can provide consumers with unbiased information about each AV product’s ability to protect their devices against real-world threats.

Conclusion

In conclusion, I have found pros and cons for both Avast and ESET. Avast scores as a top performer in the antivirus industry for online threats in the most recent tests from independent labs, but allowed the four Eicar samples in my tests, while ESET blocked all samples in my test, scoring higher for offline detection and recorded fewer false positives.

Avast is also not without recent controversy after reports found it sold sensitive user data to third parties.

Looking at the wider picture, ESET offers good value in a number of areas including the annual subscription price for its top tier product, which is almost $20 cheaper than the comparable product on offer from Avast. For users looking to protect more than five devices, Avast might work out cheaper.

When it comes to additional features and customer support, I give the edge to ESET and make them my overall winner due to them offering more features and including things like parental controls, UEFI protection and Anti-Theft for Windows PCs.
