删除以上启动项是用Autoruns删除吗？？？

“删除c:\windows\system32\dll.dll”是在正常模式下直接删除吗？？？

可以用Autoruns删，也可手动进注册表中删

删除以上启动项
重启
删除c:\windows\system32\dll.dll
要注意操作顺序，如果不重启有可能删不掉的

我按照你说的办法操作了，
1、“每次开机以后都出现 “加载C:\WINDOES\DOWNLO~1\CNSMIN.DLL时出错，找不到指定的模块”这个问题已经解决
2、开机以后查杀病毒，Trojan.PSW.Lmir.VB.n这个病毒还是存在
3、防火墙还是不能自动启动（关机之前我特意在服务项目里观察了，是设置为自动的）
4、监控中心仍然不能启动，需要删除后重新安装才能启动。
5、重新开机后在系统服务里面已经找不到防火墙和监控中心两个项目。

下面是我重新开机后的扫描

顶啊。和楼主的症状一模一样

你到底需要解决什么呀

个人认为系统还原对病毒几乎没作用,系统还原是还原配置的
