shualai.exe病毒及手工查杀方法
这是个利用ANI漏洞传播的木马群，其“动态插入进程”的功能是导致中招后杀毒困难的原因之一。
另：中招后，系统分区以外的.exe全被感染。这也是中此毒后的麻烦之处。
中招后的“症状”：进程列表中可见shualai.exe进程。
建议：用SRENG扫份日志保存，以便弄清基本情况，便于后面的手工杀毒操作。
手工查杀流程如下（用IceSword操作）：
1、禁止进程创建。
2、根据SRENG日志，先结束病毒进程shualai.exe以及所有被病毒模块插入的进程（病毒插入了哪些进程，取决于你当时运行的程序。以下是我运行该样本后的例子。）

3、删除病毒文件；清空IE临时文件夹。
4、删除病毒启动项
考虑一种特殊情况：
如果有人将autoruns等工具放在了系统分区以外，此时运行autoruns————麻烦大了！！————中此毒后，系统分区以外的.exe全被感染。
5、取消IceSword的“禁止进程创建”。
6、修复hosts文件。
注：系统分区以外的那些被病毒感染的.exe——估计是没救了。
