Once you determine that your site is clean and secure, you will need to “Request a Review” through Google Webmaster Tools. Be sure that you add (and check) both the www and non-www versions of the site.

While you are visiting Webmaster Tools, you may find more information in the [Labs | malware details] section, as well as the [More Details] line from the red malware warning bar associated with the www version of the site.
