求助,被騙子威脅了

不慎將個人住址(詳細到了門牌號)和姓名泄漏給了網上的一個騙子(就是那種通過寄假支票騙錢的),後來我意識到是騙子就沒理她了,結果她現在威脅我,"I think the finance department will have to handle this depands on your
> respond and really i wouldn't like to give anyone of my boss you informations
> for security purpose so kindly get back to me soon."

請問她知道我的個人信息會有多嚴重的後果?我該怎麽對付她?因為心裏沒底,有點害怕,請大家不要嘲笑我怕騙子,畢竟我的住址都被對方知道了.
非常感謝!!
