    ThNX a lot!! but I still have a question.
    When I run the Spybot, it still detects something but AVG doesn't.
    And how can I do to those backup files on my desktop?

    Oh yuk, I never thought of the fact that this could be your desktop: 桌面

    Can you make a folder called HijackThis on your desktop and drag and drop hijackthis.exe and all the backups in there?

    What does Spybot detect. The DSO Exploit http://forums.net-integration.net/index.php?showtopic=15308 ?

    Regards,

    Pieter

    Psst, I use a crystal ball, don't tell anyone. ;)

    DAP uninstalls without "feedback" and it is always clever to uninstall download-managers the "prescribed way" or you may get some ugly side-effects.

    Regards,

    Pieter
