You need a codesign certificate. Have a look at this blog post (from Hanselman) where you will find link to one of the CAs that you can buy codesign from.

In most cases you need to buy the codesign certificate but there are CAs (i.e. if you are open source developer) where you can get it for free. One of them is Cetrum CA (which I am currently using). Take a look here. The process of obtaining it is a torture, but the certificate itself is OK. (it doesn't work with all browsers - use FF, single signon needs to be done on every page and mails are in Polish language.)
