    I am running Windows XP/SP3 and believe I had Norton up to date. I'm not computer 'smart' at all but tried to follow every piece of advice I can find on the internet from my work laptop (not the infected one). I re-booted in safe mode, from a jump drive with malwarebytes (renamed) on it (don't have blank CDs at home). I cannot access the internet as something has shut it down and at least 5 screens pop up with fake antivirus messages (I'm assuming they are fake). I can install Malwarebytes up to 'scan' which then the computer looks for 'drive 1' and cannot find it. Is there any software to download to a USB drive, and then I start my main computer in safe mode, and run the software without the virus(es) detecting it? Yes, I did rename the Malwarebytes.exe program. Thanks!

    Welcome to Major Geeks!

    Try doing as much of the below as possible. But do not try to copy things to your thumb drive and run them from there. You need to move them from the thumb drive to where we ask you to run them from, either the desktop or from the C:\ drive.

    Try doing this first:
    * Please download TDSSKiller to your Desktop
    * Extract its contents to your Desktop so that you have TDSSKiller.exe directly on your Desktop and not in any subfolder of the Desktop.
    * Click Start > Run and copy/paste the following bold command into Run box and hit Enter.

    "%userprofile%\Desktop\TDSSKiller.exe" -v

    * Follow the instructions to type in "delete" when it asks you what to do when if finds something.
    * When done, a log file should be created on your C: drive named something like TDSSKiller.2.1.1_27.12.2009_14.17.04_log.txt which is based on the program version # and date and time run. Please attach this log to your next reply.

    NOW:

    Please read ALL of this message including the notes before doing anything.

    Pleases follow the instructions in the below link:

    READ & RUN ME FIRST. Malware Removal Guide


    and attach the requested logs when you finish these instructions.

    • **** If something does not run, write down the info to explain to us later but keep on going. ****
    • Do not assume that because one step does not work that they all will not. MGtools will frequently run even when all other tools will not.


    • After completing the READ & RUN ME and attaching your logs, make sure that you tell us what problems still remain ( if any still do )!
    Helpful Notes:


    1. If you run into problems trying to run the READ & RUN ME or any of the scans in normal boot mode, you can run the steps in safe boot mode but make sure you tell us what you did later when you post logs. See the below if you do not know how to boot in safe mode:

    2. If you have problems downloading on the problem PC, download the tools and the manual updates for SUPERAntiSpyware and Malwarebytes ( links are given in the READ & RUN ME) onto another PC and then burn to a CD. Then copy them to the problem PC. You will have to skip getting updates if (and only if) your internet connection does not work. Yes you could use a flash drive too but flash drives are writeable and infections can spread to them.
    3. If you cannot seem to login to an infected user account, try using a different user account (if you have one) in either normal or safe boot mode and running only SUPERAntiSpyware and Malwarebytes while logged into this other user account. Then reboot and see if you can log into the problem user account. If you can then run SUPERAntiSpyware, Malwarebytes, ComboFix and MGtools on the infected account as requested in the instructions.
    4. To avoid additional delay in getting a response, it is strongly advised that after completing the READ & RUN ME you also read this sticky:

    Any additional post is a bump which will add more delay. Once you attach the logs, your thread will be in the work queue and as stated our system works the oldest threads FIRST.

    Thanks but the issue starts with I cannot access the internet. I'm redirected to the fake anti-virus software. Since running programs from USB is discouraged, what are my other options? Even when I rename .exe files this virus seems to detect them and block the installation in both safe and normal modes.

    You will need to use another computer to download and copy via CD....you can use your flash drive as long as your other computer is well protected. You should first download this:
    AutoEater. Transfer this to your computer.

    Now:
    I want to see if perhaps you can get anywhere by using Safe Mode with Command Prompt. But before trying to reboot in this mode, you first need to use another PC to download the below two files:

    1. Malwarebytes Anti-Malware
    2. MGtools.exe

    Copying the above two files to the problem PC.

    • Now copy the above two files to either a CD or flash drive.
    • Put this CD or flash drive into the problem PC and see if you can use Task Manager to copy the files to the root folder of the Windows boot drive which is normally drive C. If you don't have any idea how to do this from Task Manager, try the below methods (I'll give to methods in case the 1st does not work)
      • Method 1 to Copy Files
        1. Click File, New Task (Run...) and then click the Browse button.
        2. Use the Browse windows to navigate to the CD or flash drive.
        3. Select the MGtools.exe file by clicking on it once so that it is highlighted.
        4. Then press CTRL-C to copy the file.
        5. Then navigate back to the C drive by clicking the My Computer icon in the Browse window. Select the C drive by double clicking on it.
        6. Then press CTRL-P to copy the file to the C drive root folder.
        7. Repeat the for the mbam-setup.exe file.
      • Method 2 to Copy Files
        1. Click File, New Task (Run...) and enter cmd and click OK.
        2. If the above works a command prompt window will open
        3. In the command prompt window type cd C:\ and hit the enter key. This should change the prompt in the window to C:\>
        4. Now you need to know the drive letter of the CD drive or the flash drive that you will be copying from to do the below command. I'm going to assume the drive letter is E and put that in my example command. So enter the below commands followed by the enter key:
          • copy E:\MGtools.exe
          • copy E:\mbam-setup.exe
        5. If the above copy commands work, you should get a response of 1 file copied for each command.

    • Now reboot the PC by selecting the Shutdown tab in Task Manager and then select Restart to restart the PC.
    • and press the F8 key to get to the boot menu.
    • In the boot menu, select Safe Mode with Command Prompt
    • When the PC boots up, you should eventually get a command prompt Windows to open (assuming everything works OK).
    • In the command prompt window, enter the below commands (the commands are in black bold print. Other text are just comments or explanations).
      • cd C:\
      • mbam-setup.exe
        • this will attempt to install Malwarebytes. At the end of the installation procedure, just uncheck the option to update Malwarebytes but leave the option to Launch the program checked. This should automatically run the program.
        • If it installs and runs, select Perform quickscan
        • when it finishes running, make sure your fix everything it finds and then save a log.
        • Now continue on with the next commands below
      • mgtools.exe
        • wait for MGtools to finish running. When it finishes, the C:\MGlogs.zip file will exist. Now continue on to the next steps below
      • Now hit CTRL-ALT-DEL to bring up Task Manager and select the Shutdown tab and then select Restart to restart the PC. See if it will boot in normal mode now.
    • If you can log in now and get to a normal Desktop, attach the C:\MGlogs.zip file and the log from Malwarebytes.
    • The attempt to run SUPERAntiSpyware and ComboFix per the instructions in the READ & RUN ME and also attach these two logs.
