You should contact Bitdefender Consumer Support by chat, telephone or e-mail:
Chat is the fastest way to get in touch with Bitdefender Consumer Support.
Select: Prevention & Threat Removal -> Android -> Threat Removal, click on Contact Support in the black box and then click on Chat 24/7.
NOTE: Bitdefender telephone support is not toll-free!
I think the message is in Polish and I don't really understand what it says... I would follow Gjoksi's advice and contact the Support teams for assistance in this case.
