How to report / remove a false positive

According to VirusTotal, " Fortinet" is falsely accusing www.worldpainter.net to be a " malware site" . See for example this VirusTotal report: https://www.virustotal.com/url/5f79bb11a52f9f3862e704db3ecbf8e3311e5791afb0a8bed78939612d0d2d7a/analysis/1368380897/ As you can see, Fortinet is the only one who thinks it is a malware site. As the author of the program and owner of the site I' m quite annoyed that Fortinet is tarnishing the reputation of my program. How do I go about getting this false positive removed? Fortinet' s website is an impenetrable morass of links, none of which seem to be about reporting a false positive.
