    Hi guys,

    Since yesterday I'm getting alerts from Microsoft Security Essentials about trojans in C:\Windows\assembly\GAC_32\Desktop.ini and C:\Windows\assembly\GAC_64\Desktop.ini

    First I tried bootable live CDs from AVG and Dr.Web, scanned and cleaned PC with Microsoft Security Essentials, after it didn't helped, smoked Google a little and found your forum.

    Read "READ & RUN ME", and here are the log files.

    Huge thanks in advance :)

    [​IMG] Fixing items using ComboFix
    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.
    Shut down your protection software now (antivirus, antispyware...etc) to avoid possible conflicts.
    Open Notepad and copy/paste the text in the below code box into Notepad:

    Save this file as CFScript.txt to your desktop. So now you should have both CFScript.txt and ComboFix.exe on your desktop.
    Now use your mouse to drag CFScript.txt on top of ComboFix.exe and then release.
    [​IMG]
    This will launch ComboFix.
    Note: Do not mouse-click ComboFix's window while it is running. That may cause it to stall.
    Allow ComboFix to update itself if prompted.
    When ComboFix finishes, a log will be produced at C:\ComboFix.txt
    Attach this log to your next message. (How to attach)

    Let me know how the system is running after you have completed these steps.
