Website blocked due to HTML: PhishingFB-TK warning by Avast

Hi,

While accessing my website I am getting Avast warning it blocked with HTML: PhishingFB-TK.
I’m hopelessly looking into the scripts for any signs of malicious code,
Can you please provide any string to search the code for? Or other advice?

Thank you very much!
