File Signature Verification Tool

The File Signature Verification Tool allows you to scan your computer and find unsigned device drivers. Any files that are signed can trigger a flag if modified; hence, we protect critical files with signatures. DirectX device drivers can be checked using the DXdiag tool. Start The File Signature Verification Tool by typing sigverif in the Start search text box.
