I am one of the victims of the prox fraud

I got an email to start an online form filling and they will pay us money. They send me an agreement and afer agreement i started filings forms online but i also think that they are fraud. After reading agreement i was scared because they also write they can take legal action like thing. So i started filling form. Today i searched their address in google and i came to know that this is fraud company. So should i fill their forms or not and if they send me legal action like think which i know it is fraud so i just want to confirm that is it fraud or not.
