Once you're 100% certain that your website is clean and does not contain any malware, you can request the Google team to review your website. You should know that Google reviews these requests manually. Therefore, if you have too many rejected requests, Google will flag you as a ‘Repeat Offender’. After that, you must cool your heels for 30 days before filing a new request.
