这项很可疑

重新启动到安全模式（进入安全模式的方法:重新启动电脑, 开机自动检测完后, 按[F8]键(可以一直按到启动菜单出来为止), 选择安全模式(Safe Mode)进入Windows。）

先终止下面的进程（关闭所有窗口，同时按下CTRL+ALT+DELETE，在打开的窗口中选中要终止的进程，然后按下“结束任务”或者“结束进程”，最后关闭该窗口。无法终止的话，建议使用第三方进程管理软件，比如HijackThis自带的进程管理器来终止其进程>
——打开HijackThis——配置——混合工具箱——打开简易进程管理器——选中要终止的进程——点终止进程）
C:\temp\salm.exe

请关闭所有IE界面，重新使用HijackThis扫描一次，选中下面建议修复的项目，让HijackThis修复，修复前请允许HijackThis保留备份。（如果楼主知道是安全的可以不必勾选）

然后打开我的电脑。。再点工具。。打开文件夹选项。。。查看。。。把隐藏受保护的系统文件（推荐）和隐藏已知文件类型的扩展名的勾去掉。再显示所有文件。 用WINDOWS的查找功能进行查找并删除：
C:\WINDOWS\nem220.dll
C:\WINDOWS\System32\Usign.dll
c:\temp\salm.exe

------------------------
找到这几项，蓝色字可不修复

【接3楼】
进入 C:\temp 文件夹，删除所有文件。
如果还出来，就快一些，再次删除，并把该文件夹设上只读属性
——勿删！
