My site was hacked several months ago. I cleaned it up according to the very helpful instructions in the Wiki (http://wiki.dreamhost.com/My_Wordpress_site_was_hacked). Dreamhost gave me an all-clear scan several weeks ago, and I requested a review from Google via their webmaster tools (which also show no security issues over the last 90 days). I’ve actually submitted that request 5 times in as many weeks, and had no response whatsoever.
My site still shows a “Phishing attack ahead” warning in Chrome, and Firefox won’t render my theme. I’m assuming these are related problems.
