    Hi all,

    Since yesterday, my desktop has been acting very weird. I'm pretty sure I got some kind of malware because any website I go to, I will get redirected to some junk site. I can't access google.com unless I disable Avast's shield control.

    What is going on? :(

    Thanks for the quick reply!

    I've done a full scan with malwarebytes and it found UAoOodVtCyvs.exe and wusctpegqmtylt.exe. Both were quarantined and deleted successfully.

    I did a full system scan with Avast as well and it found a virus - C:\WINDOWS\system32\c_726543.nls

    The log is automatically saved by MBAM and can be viewed by clicking the Logs tab in MBAM.
    The log can also be found at C:\Documents and Settings\Username\Application Data\Malwarebytes\Malwarebytes' Anti-Malware\Logs\log-date.txt or at C:\Program Files\Malwarebytes' Anti-Malware\Logs\log-date.txt

    I still can't go to google.com unless I disable avast's shield. If I do that, links from Google will get redirected to a random website. I'm using Firefox 11 on the desktop. These same ads appear on the bottom right of Firefox browser.

    Ok.Lets run these two....


    Please download TDSSKiller and save it to your Desktop.
    • Doubleclick TDSSKiller.exe to run the tool
    • Choose Change Parameters and make sure all the options are checked
    • Click the Start Scan button
    • After the scan has finished, click the Close button
    • Click the Report button and copy/paste the contents of it into your next reply
    Note:It will also create a log in the C:\ directory.
    =======================


    Download Combofix from any of the links below, and save it to your desktop.
    Link 1
    Link 2
    Link 3
    When saving ComboFix rename it to PCHelpForum.exe to prevent it from being blocked by malware.

    Refer to this image:
    To prevent your anti-virus application interfering with ComboFix we need to disable it. See here for a tutorial regarding how to do so if you are unsure.
    • Close any open windows and double click PCHelpForum.exe to run it.
      You will see the following image:
    [​IMG]

    Click I Agree to start the program.
    ComboFix will then extract the necessary files and you will see this:

    [​IMG]

    As part of it's process, ComboFix will check to see if the Microsoft Windows Recovery Console is installed. With malware infections being as they are today, it's strongly recommended to have this pre-installed on your machine before doing any malware removal. This will not occur in Windows Vista and 7
    It will allow you to boot up into a special recovery/repair mode that will allow us to more easily help you should your computer have a problem after an attempted removal of malware.
    If you did not have it installed, you will see the prompt below. Choose YES.

    [​IMG]

    Follow the prompts to allow ComboFix to download and install the Microsoft Windows Recovery Console, and when prompted, agree to the End-User License Agreement to install the Microsoft Windows Recovery Console.
    **Please note: If the Microsoft Windows Recovery Console is already installed, ComboFix will continue it's malware removal procedures.
    Once the Microsoft Windows Recovery Console is installed using ComboFix, you should see the following message:

    [​IMG]

    Click on Yes, to continue scanning for malware.
    When finished, it will produce a report for you. Please post the contents of the log (C:\ComboFix.txt).
    Leave your computer alone while ComboFix is running. ComboFix will restart your computer if malware is found; allow it to do so.
    Note: Please Do NOT mouseclick combofix's window while its running because it may cause it to stall.

    Just run it for a few days.Its should be fine.Ok.All done.I see no more malware.Log looks good! All that was detected is now either in quarantine or system restore, both of which we'll be cleaning out in just a minute. Congratulations, well done.

    You can now uninstall ComboFix

    • Click the Start button. Click Run. For Vista: type in Run in the Start search, and click on Run in the results pane.
    • In the field, type in ComboFix /uninstall
    [​IMG]

    (Note: Make sure there's a space between the word ComboFix and the forward-slash.)

    • Then, press Enter, or click OK.
    • This will uninstall ComboFix, delete its folders and files, hides System files and folders, and resets System Restore.

    Over the course of the fix you've used a variety of special tools to help with the cleaning process - none of these are of any use to you now that you're clean, and it's best not to have them hanging around on your computer. OTC is a small program that removes all the leftover tools and logs from cleanup of malware.

    Please download OTC to your desktop.

    Double-click OTC to run it. (Vista users, please right click on OTC and select "Run as an Administrator")
    Click on the CleanUp! button and follow the prompts.
    You will be asked to reboot the machine to finish the Cleanup process, choose Yes.
    After the reboot all the tools we used should be gone.
    Note: Some more recently created tools may not yet be removed by OTC. Feel free to manually delete any tools it leaves behind.

    Here are some tips to reduce the potential for malware infection in the future; I strongly suggest that you read them and take them to heart so that you don't have to endure the process of cleaning your computer again.
