Our drupal 7 site infected with this link :
https://click.clickanalytics208.com/s_code.js?cid=240&v=73a55f6de3dee2a751c3
Our google ads has been blocked by google due to this link.
We made:
All .js files immutable for same link;
Checked all code and database for same link.
But this didn't solve the issue.
