Ran Windows Defender Offline and now my computer won't start!

    Hi there, i'll start out by saying i'm not really tech savvy. I was updating my laptop last night and was instructed by Microsoft to use Windows Defender Offline to remove the alureon Trojan. I did just that and now my computer will not start. After Googling the problem I see that this is a rather common occurrence. I would appreciate any help that I can get. I am using Windows 7 / 64 bit.

    Thanks in advance,
    Bill

    Please do the below so that we can boot to System Recovery Options to run a scan. There will be two options to choose from. One if you do not have your Windows 7 boot DVD and another when you have your DVD.

    For x32 (x86) bit systems download Farbar Recovery Scan Tool and save it to a flash drive.
    For x64 bit systems download Farbar Recovery Scan Tool x64 and save it to a flash drive.

    Plug the flashdrive into the infected PC.

    Option1: Enter System Recovery Options from the Advanced Boot Options:

    • Restart the computer.
    • As soon as the BIOS is loaded begin tapping the F8 key until Advanced Boot Options appears.
    • Use the arrow keys to select the Repair your computer menu item.
    • Select US as the keyboard language settings, and then click Next.
    • Select the operating system you want to repair, and then click Next.
    • Select your user account an click Next.

    Option2: Enter System Recovery Options by using Windows installation disc:

    • Insert the installation disc.
    • Restart your computer.
    • If prompted, press any key to start Windows from the installation disc. If your computer is not configured to start from a CD or DVD, check your BIOS settings.
    • Click Repair your computer.
    • Select US as the keyboard language settings, and then click Next.
    • Select the operating system you want to repair, and then click Next.
    • Select your user account and click Next.

    On the System Recovery Options menu you will get the following options:
    • Select Command Prompt
    • In the command window type in notepad and press Enter.
    • The notepad opens. Under File menu select Open.
    • Select "Computer" and find your flash drive letter and close the notepad.
    • In the command window type e:\frst.exe (for x64 bit version type e:\frst64) and press Enter
      Note: Replace letter e with the drive letter of your flash drive.
    • The tool will start to run.
    • When the tool opens click Yes to disclaimer.
    • Press Scan button.
    • It will make a log (FRST.txt) on the flash drive. Please attach this file to your next reply. (See: How to attach)

    Save fixlist.txt to your flash drive.

    • You should now have both fixlist.txt and FRST.exe on your flash drive.

    Now reboot back into the System Recovery Options as you did previously.
    Run FRST and press the Fix button just once and wait.
    The tool will make a log on the flashdrive (Fixlog.txt).
    Please attach this to your next message. (See how to attach)

    Now boot into normal Windows can continue with the below.

    Running MGTools.

    Hi Tim. It boots up fine. I have to wait until this evening when I get home to run the MGTools. I am at work and can't access the internet from my laptop nor can I download the MGTools to my flash drive. My works antivirus isn't letting me access it.

    I will give an update once I run it from home.

    Thanks for all of your help so far,
    Bill
