Remove ocsp server from URL:Blacklist

Hello,

I would like to ask you how I can report a false positive alert for a URL at https://www.avast.com/false-positive-file-form.php.

Specifically, I try to add the URL
http://ocsp.athexgroup.gr
and it returns the following message:
“The form cannot be sent
Please correct the information below and try again.”

Actually this URL is an OCSP server for validating certificates and it uses OCSP protocol. When I validate an electronically signed pdf documents using Acrobat Reader, Avast antivirus reports that this URL belongs to URL:Blacklist and it does not allow to connect to this site.

Thank you,
Anna
