How to remove false positive flag? My site is clean.

Hello.

My site https://coinchanger.cc/
VirusTotal

Today I found on my website a warning from Comodo that it is phishing. But that’s not true. Can I find out why my site Comodo marks as phishing and how to prove that my site is clean?

I found out that on November 28th on Phishtank purposefully and massively malefactors added a number of sites and from new accounts specified that all of them phishing. Among these sites was mine. How to deal with such methods of competition?

Thank you in advance for your help! Have a nice day!
