Some good news anyway, the MBR doesn't appear to be infected anymore, I'm hoping TDSSKiller just upset it a bit when it it cleared out the infection. Fingers crossed

  • Insert your USB drive - the one you previously installed xPUD on - into a clean computer
  • Download xPUDtestdisk.exe and save it to the USB device
  • Double click xPUDtestdisk.exe to extract the contents to your USB device
  • Remove the USB and insert it in the sick computer
  • Boot the Sick computer
  • Press F12 and choose to boot from the USB
  • Follow the prompts
  • A Welcome to xPUD screen will appear
  • Press File
  • Expand mnt
  • sda1,2...usually corresponds to your HDD
  • sdb1 is likely your USB
  • Click on the folder that represents your USB drive (sdb1 ?)
  • Press Tool at the top
  • Choose Open Terminal
  • Type testdisk/testdisk_static
  • Press Enter
  • The TestDisk command window will open
  • Choose Create and press Enter
  • TestDisk will now detect all local hard drives
  • Use the arrow (up and down) keys to highlight the disk called /dev/sda if it represents your primary hard drive and press Enter
  • If you're not sure then note everything you see and post it for my review
  • Select Intel (even if you have an AMD processor) and press Enter
  • Select [Analyse] and press Enter, then press Enter again to run a [Quick Search]
  • When complete, press Enter to continue, then select [Deeper Scan] and press Enter.
  • When the deeper search completes, press Q repeatedly until TestDisk closes.
  • Close the Terminal Window
  • Remove the flash drive and put it back in the working computer, then post the contents of (or attach) the testdisk.log file on the flash drive.

Thanks for that

Try this please. It's similar to a command we ran earlier

  • Restart your PC, press and hold the F8 key as it restarts. You need to press F8 before the Windows logo appears. If the Windows logo appears, you need to try again by waiting until the Windows logon prompt appears, and then shutting down and restarting your computer.
  • On the Advanced Boot Options screen, use the arrow keys to highlight Repair your computer, and then press Enter.
  • Select a keyboard layout, and then click Next.
  • On the System Recovery Options menu, click on Command Prompt

  • In the command window type bootrec.exe /fixboot and press enter
  • Reboot

A GeeksToGo expert is going to take a look

  • Download NTBRHive.exe on your working computer and save it to the xPud flash drive we created earlier, in the root directory (e.g. F:\ or whatever drive letter Windows assigned that USB drive.)
  • Next, double-click NTBRHive.exe on your USB drive and let it run. You should see USB drive ready to collect hives. If you get an error message, STOP here and let me know.
  • boot the infected computer from the updated xPud flash drive.
  • Select File on the left side.
  • You need to find which are Windows partitions on the infected computer and which is the flash drive. Typically, sda* are the hard drive partitions and sdb* is the USB. Select the various \mnt\sdb1 etc. until you see the flash drive based on the files. You should see hives.sh on the right window when you have selected the correct partition.
    Posted Image
  • With hives.sh visible in the main window and only the correct sdb* selected that represents the USB drive, click Tool on the menu across the top and select Open Terminal.
  • In the terminal window type bash hives.sh (it's case sensitive) and press Enter to start the tool. The current directory will be shown, which should match the USB device, eg; /mnt/sdb1
    Posted Image

  • When prompted to type the name of the hive, type the following bold text in lowercase and press Enter.

    both

    Posted Image
  • when complete, press enter to exit the script
  • Type exit and press Enter to close the terminal window.
  • power off the computer from the menu options on the left.

When you've done that , plug the USB in your working PC. Open the usb, there should be two hive files, ntbsoft and ntbsyst. Please zip these files up to maxsubmit.zip and go to http://noahdfear.net/max/upload.php

Fullow the instructions for uploading this file. Please enter the link to this topic too, where requested - http://www.geekstogo...-7/page__st__15

Ensure your USB drive is inserted for this please

Press F10 after powering up the machine, which should bring up an 'Edit Boot Options' screen.
If it shows either of the following:

[ /NOEXECUTE=OPTIN /MININT
[ /NOEXECUTE=OPTIN IN/MINT

hit backspace to remove them, leaving only the /noexecute=optin, then press Enter to continue and see if it starts normally.

AZARL!!!! I have seen my beautiful home screen again my laptop has come back to life :D !!!! I am so happy lol. The one that came up was the MININT one but after following your instruction it was able to boot.

After shutting down and turning it back on it goes to the sane black windows recovery screen but after going to the boot options menu it is able to to boot up.

I have not done anything yet except turn on and boot the computer then shut it down again. The only change I have made is restore the default boot order.

Thank you ;)
