Customising custom post

Hi.
I’m working on a webside that is active on http://www.triggerdemo.com. I have made a custom post, called “portfolio” on this site. This is the posts that lies in the sidebar under “Min portfolio”. I have added a widget called “Simple Social – Sharing Widgets & Icons – Adds a set of social sharing widgets & icons after each post” and want it to show on my regular posts, but not on my custom posts – Portfolio.
What can I do to get this removed?
