I am experiencing a false positive, my file or site should not be detected.
VirusTotal simply aggregates the output of different antivirus vendors and URL scanners, it does not produce any verdicts of its own. As such, if you are experiencing a false positive issue, you should notify the problem to the company producing the erroneous detection, they are the only ones that can fix the issue. Please note that even if we were able to remove the flag, the users of such product would still be blocked from accessing your site.
Please find the company on our contributors page and reach out to them.
