blacklists

Recently one of our client machines was infected with a virus and I believe was spamming addresses in the user's contact list. Since then our server has been appearing on blacklists and it has been causing our e-mail to be blocked and returned by many clients. The virus has since been cleared, what can I do to get our server off these blacklists so that we will have more reliable e-mail service? Will I have to change my IP address?

Thanks,

Mike
