请教各位大虾

我的机器每次开机以后运行都特别缓慢，经查看系统进程发现winmgmt.exe进程占用内存特别大，上网查了一下，这是个系统进程，又用瑞星最新版查了一下毒，没有收获。奇怪的是每次都是开机一段时间后特慢，用一段时间后正常，百思不解，求助！

扫日志发上来

不好意思，图太小了，只能在新窗口中打开。

winmgmt.exe是windows管理服务。用于系统管理员创建windows管理脚本。

O4 - Global Startup: ipc$.bat?
难到你被别人开了IPC
删除ipc$.bat
到管理工具里面
开机运行脚本清空
开始-》设置-》控制面板
用户 看看是否有带$的用户名
有了删除
注意扫描漏洞时常更新

谢楼上两位，回6楼，ipc是我写了一个批处理加到启动项里删除的，我的控制面板用户里也没有带$的用户名，平常还比较注意漏洞的更新。
