我每次打开木马克星后总出现如下信息：

正在扫描...
扫描了 25个进程，
木马克星扫描结束.
没有发现木马，系统安全!


扫描浏览器插件:C:\WINDOWS\SYSTEM32\stdup.dll
浏览器插件扫描结束.

请问各位这个stdup.dll是什么东西，可以将它删除吗，谢谢

已经按你的方法做了，请无邪大侠，继续指教，谢谢

运行SRENG,使用系统修复--文件关联---全选---修复

========Content========
我也碰到过,好像是删除了STDUP.DLL, SUPDATE2.DLL, SPOOLSV.EXE(其中一个）, BDUPDATE， STDSVER.DLL, STDCACHE等。禁用SPOOLSV服务。用STDUP.DLL摆渡一下即可。

已经按5楼的做法做了，可是打开木马克星时显示如下：

正在扫描...
扫描了 26个进程，
木马克星扫描结束.
没有发现木马，系统安全!


扫描浏览器插件:
发现无效的浏览器插件位置:HKEY_CLASSES_ROOT\CLSID\{6A512BF7-EC78-4e8d-9841-6C02E8FA9838}

请问应如何解决这个问题，谢谢

重起一下，可能就蒸发了。

不用在乎木马克星的提示
你的系统还有异常吗？
