    Hi, I've been having some trouble with a malware that I just can't remove...

    The problem is: There are, throughout several folders of both my hard drives, some .exe files (such asqzfxie.exe wnvbkg.exe), always together with other files without extension (such as khq, kht, khu); I've tried deletting them (with shift+delete) several times, but they just keep coming back with different names and different icons, and they have also appeared on my pendrive.

    I've followed all the instructions on the "read me first" post but even though several malwares got removed, these files are still here. the only program that didn't work was RootRepeal, I kept getting error messages and it saves some crash logs.
    Once I tried Kaspersky online scan and it identified one of them as a malware and deleted it, but they just came back again...
    By the way, I used to have AVG but now I use Comodo.

    In case you need, I'll attach all the logs.

    Thanks in advance for your attention and help!
    Nathan

    ps: the crash logs from rootrepeal are like this:

    I am not seeing any of those files in your logs. You will need to give me the exact path to these files.

    Also, download and install this:
    AutoEater.

    Next I want you to download The Avenger by Swandog469, and save it to your Desktop.

    * Extract+ avenger.exe from the Zip file and save it to your desktop
    * Run avenger.exe by double-clicking on it.
    * -Do not change any check box options!!
    * Copy everything in the Quote box below, and paste it into the Input script here: part of the window:


    * Now click the Execute button.
    * Click Yes to the prompt to confirm you want to execute.
    * Click Yes to the Reboot now? question that will appear when Avenger finishes running.
    * Your PC should reboot, if not, reboot it yourself.
    * A log file from Avenger will be produced at C:\avenger.txt and it will popup for you to view when you login after reboot.
    -
    Now run Ccleaner to clean out only temp files and nothing else!

    Now run the C:\MGtools\GetLogs.bat file by double clicking on it (Note: if using Vista, don't double click, use right click and select Run As Administrator).

    Then attach the below logs:

    * C:\Avenger.txt
    * C:\MGlogs.zip

    Make sure you tell me how things are working now!

    First of all, thanks for your prompt answer!
    Well, I did what you asked me to do but those files are still here. I can't tell you if I found all of them, but I did find the following ones:

    E:\Guardar\Nathan\Meus documentos\6o ano\khq
    E:\Guardar\Nathan\Meus documentos\6o ano\kht
    E:\Guardar\Nathan\Meus documentos\6o ano\khu
    E:\Guardar\Nathan\Meus documentos\6o ano\qzfxie.exe
    E:\Guardar\Nathan\Meus documentos\6o ano\wnbvkg.exe
    E:\Guardar\Thomas\khq
    E:\khq
    C:\Downloads\khq
    C:\Downloads\khr
    C:\Downloads\khs
    C:\Downloads\kht
    C:\Downloads\khu
    C:\Users\Public\Documents\khq

    The logs are attached in this message

    The logs are attached in this message
    Thanks again,

    What is your E:\ drive? Is it a partition or a thumb drive?

    If it is a thumb drive it needs to be plugged in when the scans are done and the fix is done.

    * Run avenger.exe by double-clicking on it.
    * -Do not change any check box options!!
    * Copy everything in the Quote box below, and paste it into the Input script here: part of the window:


    * Now click the Execute button.

    * Click Yes to the Reboot now? question that will appear when Avenger finishes running.

    Thanks for the help! I did exactly what you asked and here are the logs. I hope these malwares stop coming back!
    by the way, some of the files had already been removed by comodo before I ran avenger this time (don't know why it hadn't found them before...)
    thx once again!

    Your logs are clean...I would just suggest you empty out this folder ( you can not delete items from today's date):
    C:\Users\Nathan\AppData\Local\temp\

    If you are not having any other malware problems, it is time to do our final steps:
    1. We recommend you keep SUPERAntiSpyware and Malwarebytes Anti-Malware for scanning/removal of malware. Unless you purchase them, they provide no real-time protection. They are useful as backup scanners.They do not use any significant amount of resources ( except a little disk space ) until you run a scan.
    2. If we had you use ComboFix, uninstall ComboFix (This uninstall will only work as written if you installed ComboFix on your Desktop like we requested.)
      • Click START then RUN and enter the below into the run box and then click OK. Note the quotes are required
      • "%userprofile%\Desktop\combofix" /u
        • Notes: The space between the combofix" and the /u, it must be there.
        • This will uninstall ComboFix and also reset hidden files and folders settings back to Windows defaults.
    3. Any other miscellaneous tools we may have had you install or download can be uninstalled and deleted.
    4. If we had you download any registry patches like fixme.reg or fixWLK.reg (or any others), you can delete these files now.
    5. If running Vista, it is time to make sure you have reenabled UAC by double clicking on the C:\MGtools\enableUAC.reg file and allowing it to be added to the registry.
    6. Go to add/remove programs and uninstall HijackThis.
    7. Goto the C:\MGtools folder and find the MGclean.bat file. Double click on this file to run this cleanup program that will remove files and folders related to MGtools and some other items from our cleaning procedures.
    8. If you are running Vista, Windows XP or Windows ME, do the below:
      • Refer to the cleaning procedures in step 3 the READ ME for your Window version and see the instructions to Disable System Restore which will flush your Restore Points.
      • Then reboot and Enable System Restore to create a new clean Restore Point.
    9. After doing the above, you should work thru the below link:
