Internet Explorer 8 includes additional security features when running programs from web pages. When you download a program's .exe file from the Internet or local network, Internet Explorer tries to identify the program's publisher by reading its digital signature. If the program doesn't contain a digital signature, Internet Explorer displays a warning message that the application has an "Unknown Publisher." Unfortunately, many programs don't contain this digital signature, so this message appears frequently. If you'd rather Internet Explorer not warn you about this, you can edit the registry to disable this error message.
