Unknown Publisher when I install application I wrote?

When I install my application on my computer I get a warning that the publisher is not verified. How can I change that? or do I need to worry about that when I distribute my application?

The application is written 开发者_StackOverflow社区in Visual Studio 2008 with VB.NET

On the Project Properties window, go to the Signing tab. Create/Import certificates and sign the manifests and/or assembly.

You can find more information here, with helpful links at the "See Also" section.

You can use the signtool command line program to sign exe files or msi files. I believe you might need a certificate from an official authority to change the UAC messages.
