Servicing updates consist of build and patch version releases and are released as a Micro Program Component Update (uPCU) or an Auto-update. Servicing updates provide fixes and improvements that are essential for security and stability. These updates do not add or remove functionality; they only fix or improve existing features.
Module updates

- Changelog posted: No
- Known Issues posted: No
Your ESET product checks for new components, including product modules and Detection Engine updates, many times each day. Along with our other multilayered technologies (such as Machine learning, DNA detection, behavioral detection and blocking), regular module updates help protect you against the latest known threats.
To verify that the latest product modules and Detection Engine updates have been received, you can manually check for latest product updates.
You can view the changelog history for these updates on the Virus Radar Update Info page.
Security and stability hotfixes
- Required or optional: Required
- Frequency: Rare
- Changelog posted: No
- Known Issues posted: Optional
ESET uses Security and Stability Hotfixes to address critical issues and ensure the maximum security and stability of your ESET product. The timing of hotfixes is determined entirely by their security impact. You cannot disable Security and Stability Hotfixes.
Micro Program Component Updates (uPCU)
A uPCU update is used to deliver both major releases and feature updates. There are two different uPCU updates: A differential uPCU contains some patches or files (.dup), whereas a full uPCU contains all product files except modules (.fup). During the full uPCU update, the program downloads a complete copy of the latest version and installs it over your existing ESET product.
Users can disable automatic uPCU updates in endpoint products or in ESET PROTECT.
For ESET solutions that consist of multiple components (for example, ESET PROTECT), ESET may not update the product version number each time one of the components is updated.
Auto-updates
Auto-updates replaced Micro Program Component Updates (uPCU) in ESET PROTECT 9.0 and ESET PROTECT Cloud 3.0. For more information on auto-updates, refer to ESET business products that support auto-updates.
