（阿波罗新闻网沈波报道）
现在中国和世界各地的网友中，QQ的注册用户已经超过1亿6000万。有网友透露，使用卡巴2009扫描机子，报了一个威胁...说类似木马程序...打开后发现是QQ在访问硬盘的底层。网友不免觉得疑问，QQ作为一个即时通讯软件根本没必要去访问硬盘底层，经过测试QQ根本没对硬盘MBR内容做任何改动，只是访问获取了一些什么，因此网友把相关的程序代码贴到了网上（见本文后面附的代码）。有懂得汇编的网友看过这段代码之后，留贴回答，说明这段代码的大致的作用就是在获取用户电脑硬盘的信息。
据知道内情网友留贴透露，现在警察通过qq破案已经是常事。当今中国，对于中共方面对腾讯施加压力，要求其通过qq软件来窃取用户的资料或隐私，查找定位一些人员及组织，对民众实施管制等，是很容易理解的事情。据说，迅雷等软件，也都有类似的木马后门，因此用户在使用这类软件时，需要格外注意。
下面是代码：
