GoogleSafebrowsing seems to have blacklisted one of my domain names, along with all its subdomains. It is visible on this google search page.
I'm a seasoned linux system administrator, I've checked my server several times, and I didn't find anything suspicious on it.
Of course, I could be wrong, but the point is that Google Webmaster Tools doesn't give me any extra detail: the displayed symptom is "Unknown Malware", and the list of exemple URLs is empty, which gives absolutely no hint at all...
I asked for a review from within Webmaster Tools, which came back negative.
I made a post on Google's Webmaster Central Help Forum, but didn't get any additional clue. All I got back is a value judgment on the content.
Which solutions do I have to either have more details on why Google did block my whole domain, or to reach a real support at Google?
