Computer problems?

  1. I don't know how this happened. But, my computer will not allow me to do a systerm restore, start my computer in safe mode, or install some programs. I can't install hijack this, or real player, or malwarebytes. Windows media player isn't working either. I'm also not able to hear any sound. How do I fix this?

    Please download and run the below tool named Rkill (courtesy of BleepingComputer.com) which may help allow other programs to run.

    There are 4 different versions. If one of them won't run then download and try to run the other one.

    Vista and Win7 users need to right click Rkill and choose Run as Administrator

    You only need to get one of these to run, not all of them. You may get warnings from your antivirus about this tool, ignore them or shutdown your antivirus.

    * Rkill.com
    * Rkill.scr
    * Rkill.pif
    * Rkill.exe

    * Double-click on the Rkill desktop icon to run the tool.
    * If using Vista or Windows 7 right-click on it and choose Run As Administrator.
    * A black DOS box will briefly flash and then disappear. This is normal and indicates the tool ran successfully.
    * If not, delete the file, then download and use the one provided in Link 2.
    * If it does not work, repeat the process and attempt to use one of the remaining links until the tool runs.
    * Do not reboot until instructed.
    * If the tool does not run from any of the links provided, please let me know.

    Once you've gotten one of them to run then try to immediately run the following.

    Now download and run exeHelper.

    * Please download exeHelper from Raktor to your desktop.
    * Double-click on exeHelper.com to run the fix.
    * A black window should pop up, press any key to close once the fix is completed.
    * A log file named log.txt will be created in the directory where you ran exeHelper.com
    * Attach the log.txt file to your next message.[/LIST]

    Note: If the window shows a message that says "Error deleting file", please re-run the program before posting a log - and post the two logs together (they will both be in the one file).

    ========================================================================

    Please download ComboFix from Here or 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. Please, never rename Combofix unless instructed.
    2. Close any open browsers.
    3. 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.
      NOTE1. If Combofix asks you to install Recovery Console, please allow it.
      NOTE 2. If Combofix asks you to update the program, always do so.
      • Close any open browsers.
      • WARNING: Combofix will disconnect your machine from the Internet as soon as it starts
      • Please do not attempt to re-connect your machine back to the Internet until Combofix has completely finished.
      • If there is no internet connection after running Combofix, then restart your computer to restore back your connection.
    4. Double click on combofix.exe & follow the prompts.
    5. When finished, it will produce a report for you.
    6. 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**

    Make sure, you re-enable your security programs, when you're done with Combofix.

    DO NOT make any other changes to your computer (like installing programs, using other cleaning tools, etc.), until it's officially declared clean!!!


    Download HijackThis:
    http://www.trendsecure.com/portal/en-US/tools/security_tools/hijackthis/download
    by clicking on Installer under Version 2.0.2
    [DO NOT download version 2.0.3 (beta)]

    I'm unable to run exehelper.
    and I am also unable to install hijack this.
    When I ran combo fix, i kept getting error messages and then, there was a popup that said it was not safe to continue. Download a fresh copy of combofix from: http://www.bleepingcomputer.com/combofix/how-to-use-combofix
    Note: You may be infected with a file patching virus 'Virut'

    How would I remove this without reformatting my computer?
    Is that possible? Or is that the only way?

    It may/may not be false alarm.
    What does happen, when you try to run exehelper?

    Upload following files to http://www.virustotal.com/ for security check:
    - explorer.exe located @ C:\Windows
    - userinit.exe and svchost.exe located @ C:\Windows\System32
    Post scans results.

    The good news is, that, most likely, you're not infected with Virut.
    What does the message say?

    How do you operate your computer, if you can't read Chinese?

    Download TDSSKiller and save it to your Desktop.
    Extract its contents to your desktop and make sure TDSSKiller.exe (the contents of the zipped file) is on the Desktop itself, not within a folder on the desktop.
    Go to Start > Run (Or you can hold down your Windows key and press R) and copy and paste the following into the text field. (make sure you include the quote marks) Then press OK.

    "%userprofile%\Desktop\TDSSKiller.exe" -l C:\TDSSKiller.txt -v

    If it says "Hidden service detected" DO NOT type anything in. Just press Enter on your keyboard to not do anything to the file.
    When it is done, a log file should be created on your C: drive called TDSSKiller.txt please copy and paste the contents of that file here.

    It doesn't work. It won't allow me to run it. This is getting really frustrating. Thanks for sticking with me this far.

    No problem :)
    We'll get the sucker :)

    Download OTL to your Desktop.

    * Double click on the icon to run it. Make sure all other windows are closed and to let it run uninterrupted.
    * Under the Custom Scan box paste this in:


    netsvcs
    %SYSTEMDRIVE%\*.exe
    /md5start
    eventlog.dll
    scecli.dll
    netlogon.dll
    cngaudit.dll
    sceclt.dll
    ntelogon.dll
    logevent.dll
    iaStor.sys
    nvstor.sys
    atapi.sys
    IdeChnDr.sys
    viasraid.sys
    AGP440.sys
    vaxscsi.sys
    nvatabus.sys
    viamraid.sys
    nvata.sys
    nvgts.sys
    iastorv.sys
    ViPrt.sys
    eNetHook.dll
    ahcix86.sys
    KR10N.sys
    nvstor32.sys
    /md5stop
    %systemroot%\*. /mp /s
    %systemroot%\system32\*.dll /lockedfiles
    %systemroot%\Tasks\*.job /lockedfiles
    %systemroot%\system32\drivers\*.sys /lockedfiles
    %systemroot%\System32\config\*.sav
    CREATERESTOREPOINT


    * Click the Quick Scan button. Do not change any settings unless otherwise told to do so. The scan wont take long.
    • When the scan completes, it will open two notepad windows: OTL.txt and Extras.txt. These are saved in the same location as OTL.
    • Please copy (Edit->Select All, Edit->Copy) the contents of these files, one at a time, and post them back here.
