Hi,

Since yesterday, our production sites are flagged as malicious sites by Google.

After some research, it seems that the jQuery 1.2.6 from Drupal 6 is considered as malicious by Google. So, I have not find some topics about that, none on drupal.org, none on Google,...

Is there somebody whose have the same problem or any solution?
