勾選並修復上述項目, 重新開機, 以安全模式登入windows, 刪除下列檔案:
C:\WINDOWS\upxdnd.exe
C:\WINDOWS\system32\nwizwmgjs.exe
C:\Program Files\Common Files\system\Updaterun.exe
C:\WINDOWS\system32\Ravasktao.exe
C:\WINDOWS\TIMHost.exe

C:\DOCUME~1\ADMINI~1\LOCALS~1\Temp\RavMonD.exe
C:\WINDOWS\system32\ctfnom.exe (ctfmon.exe 是正常檔案, 注意別刪錯)
C:\WINDOWS\system32\9a321.exe
C:\Documents and Settings\All Users\Application Data\Microsoft\PCTools\(刪除目錄)
在所有磁碟搜尋 RUNDLLFOROUR.EXE, 找到就全部刪除
在所有磁碟搜尋 Autorun.inf, 找到就全部刪除

P.S
1. 完成上述動作後, 可能還是留有部分衍生檔案及相關的殘餘登錄機碼, 再用防毒軟體掃描一次

2. 建議卸載 Yahoo 助手

3. KAV6 的 proactive 前攝防禦功能可監控可疑的行為, 但若用戶看不懂, 反而容易讓病毒入侵, 若你對proactive 前攝防禦功能不了解, 建議還是換別的防毒軟體吧

真心感謝 plunderer 版大一直無怨無私的幫忙需要幫助的版眾，
