    OldTimer, I was hoping you could advise me on this as I think I've seen a similar post with this same virus. I think your solution was specific to that person though. I'm open to anyone's help.
    Thanks

    Hello dvk01,
    I have downloaded the software, ran it per instructions which included quarantining the files it found. The software requested I reboot the computer to remove a couple of files. I did. I had a couple of error message boxes come up, I didn't write down what it was looking for, some dll files, I think.

    Attached are the to log files you requested. I have not tried to run Internet Explorer.
    Thanks for your help.

    Update AVG did a scheduled run and found the trojan virus again.

    next

    Download ComboFix from Here to your Desktop.

    **Note: In the event you already have Combofix, this is a new version that I need you to download. It is important that it is saved directly to your desktop**
    --------------------------------------------------------------------
    1. Close/disable all anti virus and anti malware programs so they do not interfere with the running of ComboFix.

    • Very Important! Temporarily disable your anti-virus, script blocking and any anti-malware real-time protection before performing a scan. They can interfere with ComboFix or remove some of its embedded files which may cause "unpredictable results"
    • Click on this link to see a list of programs that should be disabled. The list is not all inclusive. If yours is not listed and you don't know how to disable it, please ask.
    • Remember to re enable the protection again afterwards before connecting to the net
    --------------------------------------------------------------------
    2. Close any open browsers and make sure you are disconnected from the net. Unplug the cable if need be before running combofix.
    • WARNING: IF you have not already done so Combofix will disconnect your machine from the Internet when it starts
    • Please do not re-connect your machine back to the Internet until Combofix has completely finished.
    • If there is no internet connection when Combofix has completely finished then restart your computer to restore back the connections.
    Double click on combofix.exe & follow the prompts.
    When finished, it will produce a report for you.
    Please post the "C:\ComboFix.txt" along with a new HijackThis log for further review


    ****Note: Do not mouseclick combofix's window while it's running. That may cause it to stall or freeze ****

    Note: ComboFix may reset a number of Internet Explorer's settings, including making it the default browser.
    Note: Combofix prevents autorun of ALL CDs, floppies and USB devices to assist with malware removal & increase security. If this is an issue or makes it difficult for you -- please tell us when you reply

    Run hijackthis, put a tick in the box beside these entries listed below and ONLY these entries, double check to make sure, then make sure all browser & email windows are closed and press fix checked


    O20 - Winlogon Notify: qomnkhg - qomnkhg.dll (file missing)


    turn avg back on

    & if you do need cd to autorun which isn't really advisable

    download the attached autorun.zip

    unzip it & right click the autorun.reg file & serlewct merge

    say yes to any prompts then reboot & autoruns should be restored

    then

    *Follow these steps to uninstall Combofix and tools used in the removal of malware*
    * Click *START* then *RUN*
    * Now type *Combofix /u* in the runbox and click *OK*. Note the *space* between the *X* and the *U*, it needs to be there.
    [​IMG]


    then
    Turn off system restore by following instructions here
    for XP http://www.thespykiller.co.uk/index.php?page=8
    or for Vista http://www.bleepingcomputer.com/tutorials/tutorial143.html

    That will purge the restore folder and clear any malware that has been put in there. Then reboot & then re-enable system restore & create a new restore point. Now Empty Recycle bin on desktop

    go here http://www.thespykiller.co.uk/index.php?page=3 for info on how to tighten your security settings and how to help prevent future attacks.

    and scan here http://secunia.com/software_inspector/ for out of date & vulnerable common applications on your computer

    Then pay an urgent visit to windows update & make sure you are fully updated, that will help to plug the security holes that let these pests on in the first place

    Sounds like we've reached the end. THANK YOU! I appreciate all you've done and the time you took. I wish I could understand how you were able to figure this out, but I'm sure it beyond me.

    Thanks again!
