I need it for an older Windows system (e.g., Windows 7 or Vista) that can’t handle the latest builds. I’ve checked ESET’s official site, but they only offer the newest version.

Here’s a sample post you can use on a forum, blog, or social media: Looking for an Old Version of ESET NOD32 Antivirus (64-bit)

If anyone has a legitimate installer for something like ESET NOD32 v13 or v14 (64-bit), please let me know.

I’m aware that using outdated antivirus software comes with security risks (no new virus signature updates or patches), but this is for an offline/isolated machine.
