    Getting rid of rootkits without normal/safe mode


    Hello,
    I was wondering if it's possible to remove a rootkit without having to access normal or safe mode through windows recovery. Something like putting a program on a flash drive and running it from cmd.
    I have recently run TDSSKiller recently and removed all threats, but due to unknown problems, I can't even use safe mode anymore (I just get the desktop with nothing on it.
    I previously created a couple threads where I worked with VistaKing (why is he banned?) To remove any viruses, and the other when the problem came back but twice as bad.

    Slow/freezes even in safe mode, found obfuscator virus

    Update kb2859537 - cannot boot in normal or safe mode

    The first problem was solved by uninstalling the update, but the second now seems to be a virus.

    It would be of great help if someone could even point me in a direction because I'm not sure it is a virus since I worked through it with VistaKing.

    If you read through this thank you for your time,

    I should add the reason why I'm looking at root kits as the issue: I suspect the update kb2859537 to be part of the problem and apparently it has lots of problems when rootkits are installed. It should be noted that I couldn't find the update when searching with DISM though. So I'm pretty lost and have no idea why this is all going so badly.

    Have you seen Windows Defender Offline?

    You can use a boot partition manager called GParted. A rootkit will show up on the end of the drive as a hidden partition between 1 - 10 MB. In most cases it won't show up on Windows disk management, it will become visible with GParted.

    GParted -- A free application for graphically managing disk device partitions

    If you remove update kb2859537 & are still having problems, you could try running SFC to see if this can restore the integrity of your corrupted files. Be sure to run it 3X as it doesn't always fix everything the 1st or 2nd time.

    SFC /SCANNOW Command - System File Checker

    However, if your having that much trouble with your system, you may just want to wipe the drive & reinstall the OS. That way you get a clean start.

    Hello, how do I run GParted?
    I can't run sfc because there is a "system repair pending."
    I'm trying to do everything possible to avoid a clean start, as I have a lot of important data.

    GParted is a boot disk. It is downloaded as an .iso file. Once the file is downloaded, double clicking on it will launch your default CD Burning Software & create a boot disk.

    You may want to make this disk on another PC so as to avoid the possibility of corruption.

    TomanMT,

    I was wondering if it's possible to remove a rootkit without having to access normal or safe mode...
    Using a computer with Windows 7, 64-bit system, create a System Repair Disk:
    Instructions:
    System Repair Disc - Create
    [Note: a 64-bit System Repair Disc can only be created on a 64-bit Windows 7]
    We will use the disc shortly.

    Next, plug in a USB pen drive into the working computer.

    Go to the the Farbar Recovery Scan Tool Download
    Select the 64-bit download.
    Save the program to the >> USB flash drive.
    Remove when done.


    [You may want to print these instructions so you can have access to them. Also, you may want to read them once before you apply them.]


    Now, go to the problem computer.
    Plug in the USB pen drive which has FRST.

    Using the Windows 7 System Repair Disc just created, boot to the System Recovery Options (Option Two)
    Instructions:
    System Recovery Options

    Select: Command Prompt

    ■In the Command Prompt window, at the blinking cursor type notepad and press: Enter
    ■In Notepad, under the File menu select: Open
    ■Double-click the Computer icon on the left.
    ■Find the pen drive letter, remember what letter it is, click on it, and press: Open
    ■Close out of Notepad.

    ■Click the Command Prompt window
    ■Type x:\frst64.exe, and press: Enter
    Note: Replace the drive letter x with the drive letter of your pen drive!
    ■FRST starts, and prepares to run. Follow the prompts.
    ■Click Yes to the Disclaimer.
    ■Press the Scan button.

    The scan runs, and, the program saves the FRST.txt, on the flash drive.

    When done, click the Command Prompt window, type exit, and press: Enter
    Back at the System Recovery Options, press: Shutdown
    Remove the USB pen drive.

    Plug the USB pen drive in the working computer, and please provide the FRST.txt in your reply.
