求助,被骗子威胁了

不慎将个人住址(详细到了门牌号)和姓名泄漏给了网上的一个骗子(就是那种通过寄假支票骗钱的),后来我意识到是骗子就没理她了,结果她现在威胁我,"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."

请问她知道我的个人信息会有多严重的后果?我该怎么对付她?因为心里没底,有点害怕,请大家不要嘲笑我怕骗子,毕竟我的住址都被对方知道了.
非常感谢!!
