  1. I've followed all the steps on all of the other threads. Whenever I run an anti-virus program I am informed that I have trojan-downloader-conhook. It then tries to remove it, but none of them succeed. HJT attached.

    Hello and welcome to Techspot.

    Boot into safe mode. See how HERE. http://www.bleepingcomputer.com/forums/tutorial61.html

    Turn off system restore.(XP/ME only) See how HERE. http://www.bleepingcomputer.com/forums/tutorial56.html

    In Windows Explorer, turn on "Show all files and folders, including hidden and system". See how HERE. http://www.bleepingcomputer.com/forums/tutorial62.html

    Run a full system scan and delete whatever it finds. It may well be that the infection is resident in one of your restore points. No antivirus programme can delete anything in a restore point. Turning off system restore will delete all your restore points and any infections that are in them.

    Once you`ve done that, follow the instructions below.

    Run HJT with no other programmes open. Have HJT fix the following, by placing a tick in the little box next to(if there).

    O18 - Protocol: livecall - {828030A1-22C1-4009-854F-8E305202313F} - "C:\PROGRA~1\MSNMES~1\msgrapp.dll" (file missing)
    O18 - Protocol: msnim - {828030A1-22C1-4009-854F-8E305202313F} - "C:\PROGRA~1\MSNMES~1\msgrapp.dll" (file missing)
    O18 - Protocol: talkto - {828030A1-22C1-4009-854F-8E305202313F} - "C:\PROGRA~1\MSNMES~1\msgrapp.dll" (file missing)

    O19 - User stylesheet: C:\Documents and Settings\Yenny Su\text.txt

    Click on the fix checked button.

    Close HJT.

    Reboot into normal mode and turn system restore back on.
