一位朋友的电脑今天出现了奇怪的问题，登录后不久桌面图标和任务栏消失，有时会出现蓝屏错误：stop c0000218 unknown hard error。请偶帮助检修。

开机时按F8键，选择按最后一次正确的配置启动。

进入桌面后，发现硬盘灯狂闪，打开任务管理器，发现explorer.exe进程以是system帐户运行的，同时有userinit.exe，iexplore.exe，easy2.exe，easy9.exe，QQPlatform.exe，以及3个uusee.exe进程。

把它们全部终止了，再运行explorer.exe，桌面图标和任务栏重新出现，但一会儿又消失了。

运行 pe_xscan 扫描 log 并分析，发现如下可疑项：

估计恶意程序是朋友在浏览了利用 BaiDuBar、UUSee的漏洞的网页后侵入的~

百毒/Baidu真是一日不死，害人不止！

aliimz.sys、HBKernel32.sys都近期非常常见的恶意程序文件。

从 log 中我们可以发现恶意程序将windows系统文件rpcss.dll改为spcss.dll，然后再创建出一个假的csrss.dll。

这样我们将假的csrss.dll查杀后，系统功能将不正常。手工恢复比较麻烦~
