To protect yourself, consider using a respirator to protect yourself from breathing mold spores. Use disposable clothing or clothing that is easily cleanable following the project. Wear rubber gloves. Initially, only clean a small area, and if you begin to have symptoms stop and hire a mold remediation specialist.
