瑞星防火墙查到的信息：
Generic Host Process for Win32 Services

C:\WINDOWS\system32\svchost.exe
CmdLine=C:\WINDOWS\System32\svchost.exe -k netsvcs
包含以下：
kernel32.dll  ntdll.dll  w32time.dll  WS2_32.dll
++++++++++++++++++++++++++++++++++++++++++++++++++++++++
当我禁止svchost.exe访问网络，有时候不能浏览网页，有时候又可以。
总的感觉是svchost.exe访问网络时，网速变慢。
是不是有什么木马、流氓软件之类在利用svchost.exe？
谁来帮忙分析一下？

自己扫描一个日志看看
