You should also perform a scan of your website using a server-side antivirus application like ClamAV. This application will identify and remove most types of malware for you. However, it is important to understand that a website vulnerability or backdoor may still exist after the malware has been removed. This vulnerability or backdoor will require manual patching. Start by deleting any malware payloads on your domain that have been identified by your security scans. Malware payloads are usually standalone files that are inserted into pages or distributed to website visitors.
You may also have new pages added to your website which are full of malware or spam. If the scans have found that the pages of your website have been modified to include malware or redirects to a malware-infected page, you have two options for dealing with them.
If you are using a content management system like WordPress or Joomla, you can download source files from a trustworthy source and replace the infected files. If you have an old backup of your website that you know is clean of malware, you can also use that.
You can manually log into your website using SFTP or SSH, then manually review each of the files to determine its authenticity and validity. Start by sorting your file system by date. Log into your web server and use the diff command to compare your safe backup to the current website. If the reports provided by Google or third party security scans have identified a URL associated with malware, you can also search for that URL in your files.
This may help you locate the page that is redirecting to that malware website or including its content. You are also looking for the backdoor that the hacker may have used to gain entry into the website.
Checkin the server, access, and error logs will help you learn more about how your website was infected. You might notice a new user has been logging into the server and you can check what commands they have been running. If hackers have gained full access over your file system, they may have also inserted malware into your database. Tracking down modifications to your database may be time-consuming, but it must be done.
Google provides advice on their preferred method for cleaning each malware type. By following this advice, you can ensure that you have complied with their requirements. Once you have identified and removed the malware, take steps to improve the security of your website.
Once you are certain that any malware and backdoors have been removed from your website, request a review from Google. It usually takes a few days for Google to review a website. Once your website has been reviewed and given the all clear, you should also have Google re-crawl it.

Restoring from an uninfected backup overwrites malicious files with clean originals. However, if the server is compromised, the attacker may have replaced system binaries with rootkits and other malware.
