The process of removing a blacklist from Google due to a malware or hacked site can take several days or even weeks to complete, depending on the severity of the issue and the steps taken to resolve it. Once the malware or hacked site has been identified and fixed, the next step is to request a review from Google to remove the blacklist status. This involves submitting a request through Google Search Console and providing evidence that the issue has been resolved, such as a clean backup of the site or a third-party verification of the site’s security. After the request has been submitted, it can take several days for Google to review and verify the changes made to the site before removing the blacklist status. The exact time frame for this process can vary depending on the severity of the issue and the workload of the Google review team.
