What is updater.exe?
kaspersky-updater is the background updater component of Kaspersky security products. It periodically contacts official servers to fetch antivirus definitions, product patches, and feature updates, then applies them automatically to keep protection current without interrupting your work.
Technical overview: updater.exe operates as a Windows service coordinating update downloads, signature verifications, and scheduled checks. It runs under Kaspersky Lab's digital signature and communicates with the product UI to apply verified updates.
Quick Fact: Kaspersky Updater was designed to ensure timely threat definitions and module updates while minimizing user disruption; it runs in the background and uses secure channels.
