Since the introduction of Windows XP, executable files have been able to assigned digital signatures. This ensures that files cannot be altered by third parties without being noticed, which protects the files from being used a carriers for viruses and malware.
When an Autostart program runs for executable files, there is a warning window which asks the user if the software manufacturer is trusted or not. The software manufacturer can only be displayed if the digital signature is available and valid.
The KSSW-FrontendMenu Software uses this kind of signature
Checking the Digital Signature
In Windows Explorer, right-click on an executable file and select "Properties" from the context menu. In the Properties Window, click on the Digital Signature tab.
