Help required - Malware removal

  1. Hi,

    I'm wondering is someone can give me some help or advice on virus or malware removal.

    The symptoms were the machine running very slowly, and my normal antivirus software (AVG Anti-Visus Free) finding some infections.

    I then noticed that I could not run "taskmgr", "cmd" or "regedit" as another process was using the file. When I run in Safe Mode I can run these.

    A bit of google-ing for others with similar symptoms brought me to the "8-step Viruses/Spyware/Malware Preliminary Removal Instructions" post on this forum.

    I've followed the steps, and any of the "will clense on reboot" does not apprear to be working.

    I've attached the following log files...
    (1) AVSCAN-20081224-113235-88729D7B
    (2) mbam-log-2008-12-26 (14-48-40)
    (3) SUPERAntiSpyware Scan Log - 12-24-2008 - 20-14-41
    (4) hijackthis 2008-12-26 20-00

    I have virus scanned with...
    (1) AVG Anti Virus Free (latest version). This is now showing no infections, and no warnings.
    (2) Avira AntiVir Personal Free (latest version). Showing 1 detection and 2 warnings (log file attached.)

    Any help appreciated.

    Please uninstall one antivirus programme. This is because running more than one AV programme will slow your system and can cause conflicts.

    You need to rename HijackThis.exe to Crusty.exe. This is because some malware can hide from HijackThis.exe. Follow these instructions in order to do so.

    Go to the C:\Program Files\Trend Micro\HijackThis\HijackThis.exe file and right click on HijackThis.exe. Choose rename. Click in the title box and hit the enter key to clear what`s there.

    Now type Crusty.exe into the title box and hit the enter key. Right click on the Crusty.exe file and choose "Send to desktop Create Shortcut".

    You can now close the HJT directory.

    You might want to copy and paste these instructions into a notepad file. Then you can have the file open in safe mode, so you can follow the instructions easier.

    Boot into safe mode, under your normal user name(NOT THE ADMINISTRATOR ACCOUNT). See how HERE.

    In Windows Explorer, turn on "Show all files and folders, including hidden and system". See how HERE.

    Open your task manager, by holding down the ctrl and alt keys and pressing the delete key.

    Click on the processes tab and end process for(if there).

    winlogin.exe<Not to be confused with winlogon.exe

    Close task manager.

    Run HJT with no other programmes open(except notepad). Click the scan button. Have HJT fix the following, by placing a tick in the little box next to(if there).

    O4 - HKLM\..\Run: [Windows Logon] C:\Documents and Settings\Admin\winlogin.exe

    O20 - AppInit_DLLs: avgrsstx.dll,C:\WINDOWS\System32\dmusic32.dll

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

    O20 - Winlogon Notify: cc979ab4509 - C:\WINDOWS\

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

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

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

    Click on the fix checked button.

    Close HJT.

    Locate and delete the following bold files and/or folders(if there).

    C:\Documents and Settings\Admin\winlogin.exe

    Reboot into normal mode and rehide your protected OS files.

    Download combofix.exe to your desktop. Double click combofix.exe & follow the prompts. A window will open with a warning. Type "1" (and Enter) to start the fix. When the scan completes it will open a text window. Please attach that log back here together with a fresh HJT log. Caution - do not touch your mouse/keyboard until the scan has completed. The scan will temporarily disable your desktop, and if interrupted may leave your desktop disabled. If this occurs, please reboot to restore the desktop.

    Combofix will automatically save the log file to C:\combofix.txt

    Thanks so much for the help. It appears to have worked.

    I followed all the steps, except where the files were not found.
    (1) When running task manager, the process winlogin.exe was not there
    (2) After running HJT, 020 - AppInit_DLLs: avgrsstx.dll was not there (although I'd uninstalled AVG Antivirus so that could explain it.)
    (3) The file C:\Documents and Aettings\Admin\winlogin.exe was not found (for any user.)

    I can now run "cmd", "regedit" and <ctr><alt><del> brings up the task manager. So it it looking good.

    I've attached the combofix log and the HJT log.

    Is there anything else I need to do?

    Go to add remove programmes in your control panel and uninstall anything to do with(if there).

    Close control panel.

    Open notepad and copy/paste the text in the code box below into it:
    NOTE* make sure to only highlight and copy what is inside the quote box nothing out side of it.
    Also ..

    Pay particular attention to this:

    Make sure the word File:: is on the first line of the text file you save (no blank line above it, & no space in front of it)

    Save this as CFScript.txt

    Then drag the CFScript.txt into ComboFix.exe as you see in the screenshot below.


    This will start ComboFix again. After reboot, (in case it asks to reboot), post the contents of Combofix.txt in your next reply together with a fresh HJT log.

    Thanks again.

    No sign of any of thesse in the add/remove programmes list.
    - RegSeeker
    - RegistryFix
    - frostwire-4.17.0

    Although I noticed they all existed as folders in C:\Program Files

    Ran combofix as requested. (This was done in normal mode not in safe mode.)

    ComboFix and HJT logs both attached.

    Your logs are clean.

    Unless you're still having problems, you should be good to go.

    If you're not having problems, do the following.

    Please download OTMoveIt by OldTimer OTMoveIt.exe, unzip it and place it on your desktop.

    1. Double click OTMoveIt.exe to launch it.
    2. Click on the CleanUp! button.
    3. OTMoveIt will download a list from the Internet, if your firewall or other defensive programs alerts you, allow it access.
    4. You will be prompted to allow the clean up procedure, click Yes
    5. When finished exit out of OTMoveIt

    Turn off system restore.(XP/ME only) See how HERE.

    Now, turn system restore back on. This will have deleted all your old restore points and any nasties that are in them. It will also have created a new, clean restore point.
