Our domain is flagged as dangerous even though we have fixed the problem.

Hello, I think you need to identify the blacklist source (it could be Google). Then request a review. Not sure if you wait how long it could take. Is it a problem specific to Firefox? Is the screen capture from Google Chrome? According to Google documentation : Be sure that the problem is truly fixed before requesting a review; if the problem still exists, you will only prolong the period of time that your site is flagged as problematic. Text and translation of the problem : ----- Dangerous website Attackers on the site you intended to visit may trick you into installing software or reveal things like your password, phone or credit card number. Chrome strongly recommends that you go back to the correct websites. Read more about this warning Enable extended protection to get Chrome's best features -----
