The standard file extension of the official GameBuff installer is .exe (for example: GameBuff_Setup.exe). To ensure the safety of your computer, we recommend verifying the authenticity of the installer package through the following two steps: 1. Check the extension: Make sure the file ends with .exe, not .bat, .zip, or any other extension. 2. Verify the digital signature (core criterion): Right-click the installer file → select Properties → click the Digital Signatures tab. The official genuine installer must carry the signature of 【Game Buff Technology Co., Ltd.】. Expert tip: Do not run any file whose digital signature is inconsistent or shows “Not signed.”
