As of late 2025, ESET has moved toward merging "ESET Cyber Security Pro" and "ESET Cyber Security" into a unified platform. Users on version 6.x are encouraged to upgrade to the latest version of ESET Cyber Security for improved stability and modern performance. Core Features of the 6.5.x Series
While version 6.5.600.2 was a bug-fix release, the 6.5 series generally included:
Integrated tools to manage children's online experiences, a hallmark of the "Pro" version.
Resolution of "kernel panics" related to certain hardware drivers (like Logitech utility software) and stability issues during product uninstallation.
Real-time protection using the ESET LiveGrid reputation system to whitelist safe files.
It replaced version 6.5.600.0 and was eventually succeeded by later builds like 6.5.600.5, which addressed further issues such as custom settings being reset after a product upgrade.
ESET Cyber Security Pro version was a critical maintenance update released in early 2020 specifically to address compatibility issues with security patches in macOS . Key Release Details
