We are seeing a big issue on Google for the last few days. Whenever a site got blacklisted, you had the option to request a review after the site was clean. Something like that:
Unfortunately, Google has discovered harmful code on your site.
Some of the infected pages are listed below. Google is providing these pages as a starting point in your investigation and clean-up process. Please also use StopBadware.org’s Guide to Cleaning and Securing your Website to identify, address, and prevent any malware activity on your site. Important: Simply removing harmful code from individual pages is not enough to fix the problem; you must also ensure that you identify and address the underlying vulnerabilities that allowed your site to be contaminated.
We were able to see this issue on a few sites ourselves (that we fixed during the weekend) and we still have no option to review them. Quite a few people are also complaining about it on their foruns:
Another interesting thing is that the main page for the webmasters tools is not showing the malware warning as well (you have to click on Diagnostics->malware to see it). All in all, a bad day to be blacklisted.
If your site is hacked and/or blacklisted, we can help. Contact us at email@example.com or go to sucuri.net to get your site blacklist-free to get your site blacklist-free.
