斑竹!你好,我是菜鸟,我的机器中了灰鸽子,每次上网就有病毒感染,瑞星杀完后反复出现,后来发现病毒源是lsass.exe程序.在WENDOWS目录里删除了lsass.exe重起后好象没了,请问我的操作有问题吗?删除了lsass.exe系统文件有关系吗?谢谢!!!!!!!!!!!!

真正的lsass.exe系统文件在c:\windows\system32\目录下

您删除的文件在哪儿？

【回复“影子110”的帖子】我已在WINDOWS下删除了lsass.exe 文件.现在好象病毒没有了.还用进一步操作吗?谢谢各位!!!!!!!!!!

修复O23 - NT 服务: Management Instrumentation - Unknown owner - C:\WINDOWS\lsass.exe (file missing)
按如下步骤：
1.打开注册表，HKEY-LOCAL-MACHINES\SYSTEM\CURRENTCONTROLSET\SERVICES,删除左边Management Instrumentation
2.重启系统，在“文件夹选项”的“查看”面板中勾选“显示系统文件”、“显示所有的文件和文件夹”两项，点击“确定”按钮。然后在C:\WINDOWS\下寻找病毒文件名lsass.exe ，lsass.dll,lsass_hook.dll,可能还有lsasskey.dll,全部删除。

【回复“七彩黄花菜萱草”的
谢谢指点!可是我不敢轻易删除注册表内容啊!可以删除吗?不会出问题吧?现在病毒不见了,还用删除注册表项吗?(我是菜鸟,呵呵.不要嫌麻烦撒,请指教!谢谢!!!!!)
