Verify your download

Filzyx installers are not code-signed yet, so Windows SmartScreen may show a warning for a new file. You can verify that the installer is the exact build we published by comparing its SHA-256 hash with the value on the product page or in SHA256SUMS.txt.

Windows PowerShell

Get-FileHash .\KeyboardTester-Setup-0.1.0.exe -Algorithm SHA256

Command Prompt

certutil -hashfile KeyboardTester-Setup-0.1.0.exe SHA256

The value must match the SHA-256 shown on the product page. If it does not, delete the file and download it again from https://filzyx.com/.

Why does SmartScreen warn?

SmartScreen reputation is tied to the file hash and the publisher certificate. Filzyx does not use a code-signing certificate, so a fresh installer has no reputation yet and Windows may ask you to confirm that you want to run it. The hash check above is the reliable way to confirm the file's integrity.

Antivirus false positives

Some heuristic engines flag small Windows utilities that work with files, network settings or startup entries. If your antivirus reports a Filzyx installer, please send us the vendor name and the detection name through the feedback form so we can submit a false-positive report.
