IE 出現不回報, 上不到網及中木馬

近日IE頻頻出現不回報error, 上不到網~
uninstall IE了, 再install也能, 連上norton online scan都不能!

我用firefox用housecall online scan掃到這些病毒及木馬, 但有些不能remove~
上次我用norton 掃過有木馬:
C:＼WINDOWS＼Setup.dll 感染了 Trojan Horse
C:＼WINDOWS＼system32＼Wincld32.dll 感染了 Trojan Horse

這次我用housecall掃到的result:
1. TROJ_GEN.RZ3077 (無寫感染file: 1 infected)
2. TROJ_NODEF.BG (1 infected )(C:＼WINDOWS＼system32＼Wincld32.dll) <<這個依然remove不到!
3. CRCK_KEYGEN (1 infected)(無寫感染file)
4. HKTL_USURFE (1 infected )(C:＼Documents and Settings＼Owner＼My Documents\u94.zip!)
5. CRCK_WINVI.A(1 infected )(C:＼Documents and Settings＼Owner\My Documents＼WinAVI76_big5.rar!)
6. HTTP cookies (2 detected)

我按f8 進入安全模式, 又找不到那2個檔案:
1. C:＼WINDOWS＼Setup.dll 感染了 Trojan Horse
2. C:＼WINDOWS＼system32＼Wincld32.dll 感染了 Trojan Horse

但已沒有不回報IE error~

但不知為何在"執行"打網址上網, 佢會彈個"這個檔案沒有執行這個動作的關聯程式, 請在[資料夾選項]來建立關聯。"的box~

及登入microsoft update windows時, load網頁很長時間都不能顯示網頁~
下載了IE 8 exe install時, 久久未能安裝完成, 只停留於"正在下載"那part的步驟.....

在msn 按"信件" icon, 平時可以即時彈個browser出黎: ie 或 firefox; 但現在按了也沒反應。


在house call 曾經顯示過infected :
1. cookies double click
2. cookie serstym <<好似係咁串~

請問如何解決這些問題呢? 謝謝!!
