Fix Wordpress Website For Google Ads Approval

Need someone to fix website. I have a wordpress website that was hacked by malicious code. The maleware is removed from website and its working fine now but website is still not approved for google ads. Checked many things but can't find anything malicious on website however google team still disapprove site saying that its infected and must be cleaned before approval.

The website must be cleaned and approved by google in order to consider project as complete. Furthermore website must be secured in order to prevent hacking in future.
