    Hey there,

    I've got a problem with a trojan I got somewhere. Spybot identifies the thing as win32.agent.qt and tries to remove it. It seems to be successfull in the beginning but the trojan is there again after I rebooted the computer. And can't get rid of this thing!

    Here is the Logfile of HijackThis after I removed the thing again with Spybot.

    Logfile of HijackThis v1.99.1
    Scan saved at 21:22:06, on 07.02.2008
    Platform: Windows XP SP2 (WinNT 5.01.2600)
    MSIE: Internet Explorer v7.00 (7.00.6000.16574)

    Can anybody help me?

    Tom

    Hey!

    First of all, thank you for your help!!! I really don't know what to do otherwise.

    I followed the instructions in the "Read and Run me first..."-Thread. But there wasn't really a satisfactory result.

    As I wrote before Spybot recognizes the thing as Win32.Agent.qt and also tries to remove it. But after some time it's there again. And I can't find where it's sitting. Spybot says it's a Registry-Database-Value and gives the following Path: HKEY_USERS\S-1-5-21-2415682206-914002717-4149115087-1005\Software\Microsoft\Internet Explorer\New Windows\Allow\*.starsdoor.com

    I included all the logs from three tools mentioned in the "Read and run me first.."-thread but the MGTools gave me Error-message Type 4 because I don't have .NET Framework Software installed. (I don't wanna have it) I included the logfiles anyway.

    I really hope you can help me!

    Thanks again!

    Tom

    Although you now appear to be using Avast as your antivirus, you still have items from Symantec hanging around. Please run this:Norton Removal Tool (SymNRT)

    Uninstall the below old versions of software:
    Java 2 Runtime Environment, SE v1.4.2_05


    Now we need to use ComboFix to remove a bunch of malware files.
    • Make sure that combofix.exe that you downloaded while doing the READ & RUN ME is on your Desktop but Do not run it!
      • If it is not on your Desktop, the below will not work.
    • Open Notepad and copy/paste the text in the below code box into it (make sure you scroll all the way down in the code box to get all lines selected ):
    Code:
    File::
    C:\WINDOWS\mrofinu572.exe.tmp
     
    Folder::
    C:\WINDOWS\system32\dp1
    C:\WINDOWS\system32\feq9
    C:\WINDOWS\system32\nGpxx01
     
    Registry::
    [HKEY_LOCAL_MACHINE\software\Microsoft\windows\currentversion\Explorer\ShellExecuteHooks]
    "{E180F496-8A4B-44E2-9FE0-0364E345DB7F}"=-
    [-HKEY_USERS\S-1-5-21-2415682206-914002717-4149115087-1005\Software\Microsoft\Internet Explorer\New Windows\Allow\*.starsdoor.com]
    [HKEY_USERS\S-1-5-21-2415682206-914002717-4149115087-1005\Software\Microsoft\Internet Explorer\New Windows\Allow]
    "*.starsdoor.com"=-
    
    • Save the above as CFscript.txt and make sure you save it to the same location (should be on your Desktop) as ComboFix.exe
    • At this point, you MUST EXIT ALL BROWSERS NOW before continuing!
    • You should have both the ComboFix.exe and CFScript.txt icons on your Desktop.
    • Now use your mouse to drag CFscript.txt on top of ComboFix.exe
    • Follow the prompts.
    • When it finishes, a log will be produced named c:\combofix.txt
    • I will ask for this log below
    Note:

    Do not mouseclick combofix's window while it is running. That may cause it to stall.


    After reboot, now install the current version of Sun Java from: Sun Java Runtime Environment

    Now run Ccleaner!

    Now run the C:\MGtools\GetLogs.bat file by double clicking on it.

    Then attach the below logs:
    • C:\ComboFix.txt
    • C:\MGlogs.zip
    Make sure you tell me how things are working now!

    Hey there!

    I did everything you said and the trojan is gone! A friend of mine who knows a little bit about this stuff came around and also confirmed that nothing's there any more! :)

    Thank's a lot for your advice and especially for the hint with the Norton-Removal-Tool. I always had problems removing Norton Antivirus after the test period.

    Thank's again! And all the best!

    You should attach the requested follow up logs so we can be sure.
