The Site Ahead has Malware

I am in the process of cleaning up a website. I have run defender a few times and hardened the site. I am currently getting the dreaded google red screen. The original site is at I moved it to to clean it up and manage the hosting. Is there something I could be overlooking. I have also reloaded the core wordpress files. Thanks,

Issue - I have included an image of the warning.(getting this when any nav link is clicked.)
Steps Taken - Removed all plugins, removed all non-essential themes, reinstalled wordpress core.

Other sites that I manage with Defender and Hardening have remained clean.
