    Computer won't boot after using Defender offline


    Well, it seems this is a common problem. I'm mildly tech savvy, but this has me beat.

    Kid's college computer got Alureon, ran Defender Offline from a USB which appeared to work to remove the virus, but now it's in the start cycle of black and white Acer screen, a quick flash from a blue screen, repeats this once or twice more, then into the system repair and then recovery. None of these worked. Trying not to do a total factory reset due to college things saved. No Windows discs. We were sure to reset the BIOS for the hard drive to boot first after using the Defender USB.

    The (previously, I hope) infected computer is an Acer Win7 home premium 64 bit. Clean computer is a Vista home premium 32 bit which appears to have issues downloading some 64 bit things to a USB because it's "not compatible".

    School starts again in a few days and we REALLY cannot afford the expense of a new laptop suddenly if I can get around this somehow. I'm not a super tech person but I can follow instructions! Any help on where to start is much appreciated, and I apologize in advance for much of my tech ignorance.

    Probably a dumb question - the clean computer is 32 bit and the infected is 64. Do I download the 32 version on the clean and it will be okay to use on the infected 64 bit?

    Download the 64-bit version save it onto a USB flash drive . Plug the USB flash drive into the infected PC . Boot to the System Recovery as it says to do select command prompt . Inside the command prompt find your USB drive letter by using Diskpart ( see above instructions ) then go from there .

    Never mind, got it saved. Thanks.
    *********************
    Thank you. My Vista 32 bit will download the 64 bit but won't save it to the USB drive, says the version is "not compatible". Is that normal? Maybe I'm missing something. Sorry for my ignorance.

    I Downloaded FRST64.exe on a 32 bit OS . You could download it but not run it . Plug your USB flash drive into the 32bit PC . Open the downloads folder right click on FRST64.exe and select Send To choose removable disk . Should work . Downloading works running the program won't on a 32 bit .

    click on the Save button inside Notepad.

    Unplug the USB Flash drive from the 32-bit PC plug back into the 64-bit PC Open FRST64.exe like you did before . This time click on the [Fix] button . Once done it will create a new log called Fixlog.txt it will be in your USB Flash drive.

    Restart the PC and see if you could login to your Desktop on the 64-bit PC.

    Yes! It logged on and is to the desktop. But it was verrrry slow to get to the desktop, took several minutes to go from the login password screen to a black screen to the desktop. Desktop seems to be okay after it finally loaded.

    Sweet. Run the next tool . We are not done cleaning the PC

    TDSSKILLER

    download link TDSSKiller

    Save to the Desktop

    Right-click the program and select


    When the TDSSKiller console opens, click on: Change Parameters
    Under Additional Options, place a check in the box next to: Detect TDLFS File System

    Click: OK


    Press: Start Scan


    If a suspicious object is detected, the default action is Skip, leave it as is, and click on: Continue
    If malicious objects are found, they show in the Scan results.
    Ensure Cure (the default) is selected, then click: Continue > Reboot now, to finish the cleaning process.
    (Note: If Cure is not available, select Skip, >>Do not select: Delete<<)


    When done, the tool outputs its log to the disk with the Windows Operating System, normally C:\
