Security Best Practices

  • Never use third-party "update downloader" tools. Only use ESET’s official offline generator.
  • Do not manually edit the .ver file. It is hashed; modifying it will break the signature check.
  • Update frequently. ESET releases multiple signature updates daily. An offline update older than one week significantly reduces protection efficacy.

Check for Updates: Open the main program window and navigate to the Update tab. Click Check for updates to immediately download the latest signature files.
