If the driver signature is disabled, it means that the modified driver can be installed and used normally without verification. Few drivers have been modified, such as Trojans.

A signature driver is a device driver that contains a digital signature. Digital signature is an electronic security token, which can indicate the publisher of the software and whether anyone has changed the original contents of the driver package. If the driver is signed by a publisher who uses a certificate authority to verify its identity, you can be sure that the driver really comes from this publisher and has not been changed.
