Svchost.exe是NT核心系統非常重要的檔，對於Windows 2000/XP來說，
不可或缺。Svchost進程提供很多系統服務。不建議刪除。

F2 - REG:system.ini: UserInit=userinit.exe,C:\WINDOWS\system\svchost.exe


Delete this line and try to scan for virus afterward.

勾選並修復這一項:
F2 - REG:system.ini: UserInit=userinit.exe,C:\WINDOWS\system\svchost.exe

重新開機後刪除 C:\WINDOWS\system\svchost.exe

P.S
svchost.exe 若不是在 C:\WINDOWS\system32\ 目錄, 肯定是假貨, 放心刪吧

感謝以上各為前輩的指教

THX

請教一下，由 HijackThis 所列出來這一行並無顯示任何警告錯誤訊息，如何得知此行是有問題的呢？:on_47:

靠經驗判斷囉 :on_44:

很多木馬會偽裝成系統檔案
判斷檔名:
例如 svch0st.exe, expIorer.exe(看看與真正的 explorer.exe 有何差別)...若不注意就會被矇混過關
若不知道是什麼檔案, 就看看檔案"內容", 若無數位簽章, 多半有問題

若檔名一樣, 就判斷路徑:
系統檔案不會出現在不該出現的地方
就如上面提到的, svchost.exe 若不是在 C:\WINDOWS\system32\ 目錄, 肯定是假貨
