If my computer is found to have copyrighted material, what steps can Harvard take as a result?

When a computer on the Harvard Network is implicated in copyright infringement, the individual responsible for that computer is notified about the notice by the Harvard University IT Security department or the local DMCA liaison and asked to cease and desist immediately from downloading, copying or distributing copyrighted material in violation of the law. Repeat infringements may result in termination of network access and be brought to the attention of the appropriate dean.  In appropriate circumstances, Harvard will terminate the network access of users who are found to have repeatedly infringed the copyrights of others. Schools or departments may pursue disciplinary action as well. Harvard's copyright policy is available here.
