My site shows the "This site may be hacked flag" underneath my domain in search results. This only shows on homepage and no further warning shows when visiting the page.
I have checked within my Google webmasters search console for a bit more information on this and run various malware scans as well as looking over the code myself without finding anything suspicious. Transparency report shows similarly no issues. https://transparencyreport.google.com/safe-browsing/search. I have also checked with sites like Quttera and IsTtHacked.com and that has flagged nothing either. Magereport shows no issues also and am running the latest version of Magento (2.2.3). https://www.virustotal.com also shows the site to be clean.
I want to know if there is any other way to check why google has flagged this and what they have detected (or if anyone can see anything suspicious as i cannot) or how i can contact google for an explanation of this?
