    cant reboot after windows defender offline


    hello, i read another similar but not sure what will apply in my case.... After being notified my computer was infected I followed the suggestion to use Windows Defender Offline to remove the trojan. Once completed, and having cleaned the trojan, the computer would not reboot. It has a black screen with a flashing curser in the top left. I cannot even get to a login screen or any other screen. I am typing this on a laptop as my desktop cannot even be used now. The infected computer is a Dell using Windows 7 professional (sadly, not sure if its 7 or 8)64bit. When I restart, I can do f2 or f12 (but not f8 nor f10). been trying to fix all day. please help if you can

    gchen,

    Please try the following:

    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.

    Please plug in a USB pen drive into a clean working computer.

    Go to the Farbar Recovery Scan Tool Download
    Farbar Recovery Scan Tool Download
    Select the download that applies to your system.

    [Note: To find out if it is 64-bit or 32-bit, check the Model of your Dell, and its serial number.
    Go to the Dell website, and see if you can find out. If this is not possible, then, try one version of the tool (64-bit), and if it does not work, then use the other (32-bit).]

    Save the program to the >> USB pen drive.
    Remove USB pen drive from the working computer when done.

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

    Start the computer, and tap the F8 key until you get to the Advanced Boot Options menu
    Use the arrow keys to select the Repair your computer menu item

    From there...
    Select your language settings, and click: Next
    Select your User account and click: OK (If you did not set a password, leave blank.)

    On the System Recovery Options you get the following options:
    Startup Repair
    System Restore
    Windows Complete PC Restore
    Windows Memory Diagnostic Tool
    Scan your computer's memory for errors
    Command Prompt

    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:\frst.exe, and press: Enter

    [Note:
    1. Replace the drive letter x with the drive letter of your pen drive!
    2. If the system is 64-bit, use x:\frst64.exe]

    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 a report, FRST.txt, on the pen 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 from the problem computer.

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

    thanks for responding. i was never able to get the f8 key to work so i could access the frst on the problem computer. i gave up and took it to be serviced, said the hard drive was damaged. cleaned all and put all back. this was way past my scope of troubleshooting. thanks so much though
