ESET Security is a Windows antivirus built around the ESET LiveGrid scanning engine, aiming for strong protection with a small system footprint. The installer is fetched from ESET's own server, download.eset.com. The current build is version 19.2.10.0, released on August 24, 2026, and weighs 85.6 MB.
A scanning engine tuned to stay out of the way
The defining claim is lightness. The publisher, ESET, spol. s r.o., describes the product as fast enough for gamers and everyday users who do not want interruptions, with an install-and-forget approach.
Protection rests on the LiveGrid engine and on AI-based technologies. According to the publisher, these target viruses, spyware, trojans, worms, adware and rootkits without slowing the system. No benchmark figures are available, so the speed claim is the publisher's own.
What a session with ESET NOD32 looks like
After installation the program is meant to run quietly in the background and watch for attacks and malicious software. The package ID is ESET.Nod32, and the listing is priced at 0 with a proprietary licence.
The newest release changes one step you will notice. SHA256 is now enabled by default, so an initial scan must run before that setting takes full effect. The import and export options now sit in two separate windows, and lists have a unified option for adjusting headers.
Where it sits next to Malwarebytes and ClamAV
The alternatives are Malwarebytes, ClamAV, ClamWin Free Antivirus, AdwCleaner, BitDefender Agent and Emsisoft Emergency Kit. No comparison data is available, so no ranking is given here.
ESET positions itself as a complete, always-on security product. It is tagged under anti-malware, antivirus and protection. Readers who want a different scanning model can look at the names above.
What's new in 19.2.10.0
Version 19.2.10.0 adds web control in ESET Small Business Security and network attack protection in ESET Safe Server. It also enables SHA256 by default, which requires an initial scan, and splits import and export into two windows.
