May I ask have you tried reaching out to Cloudflare Trust & Safety team about your domain/issue?
Have you checked your inbox if you received any email from T&S so far?
I’d scan everything connected to the website and domain for malware or any malicious php script, javascript file, etc. and then select the option on the overview tab to review the site, if it’s there.
Aside from that, I am afraid we would have to wait for Trust & Saftey to review & respond.
Kindly, I’d suggest you to write a ticket to Cloudflare support due to your account and/or domain issue:
Login to Cloudflare and then contact Cloudflare Support by clicking on the Get More Help button. If you get automatic reply, reply and indicate to it you need more help and reference to this topic
Or send an an e-mail to support[at]cloudflare[dot]com from your e-mail associated with your Cloudflare account
Yes, i have gone through my site and removed the infected files and site is totally safe and submitted review request from overview but still in review mode after 24 hours.
