Thank you for the clarification.

Were you experiencing any computer issues before this disk issue? If so, what were they?

Rather than run AVAST, please do this if possible:

Please download Malwarebytes Anti-Malware and save it to your desktop.Download Link 1
Download Link 2
MBAM may "make changes to your registry" as part of its disinfection routine. If using other security programs that detect registry changes (ie Spybot's Teatimer), they may interfere or alert you. Temporarily disable such programs or permit them to allow the changes.
  • Make sure you are connected to the Internet.
  • Double-click on mbam-setup.exe to install the application.
    For instructions with screenshots, please refer to the How to use Malwarebytes' Anti-Malware Guide.
  • When the installation begins, follow the prompts and do not make any changes to default settings.
  • When installation has finished, make sure you leave both of these checked:
    • Update Malwarebytes' Anti-Malware
    • Launch Malwarebytes' Anti-Malware
  • Then click Finish.
MBAM will automatically start and you will be asked to update the program before performing a scan.
  • If an update is found, the program will automatically update itself. Press the OK button to close that box and continue.
  • If you encounter any problems while downloading the definition updates, manually download them from here and just double-click on mbam-rules.exe to install.
On the Scanner tab:
  • Make sure the "Perform Quick Scan" option is selected.
  • Then click on the Scan button.
  • If asked to select the drives to scan, leave all the drives selected and click on the Start Scan button.
  • The scan will begin and "Scan in progress" will show at the top. It may take some time to complete so please be patient.
  • When the scan is finished, a message box will say "The scan completed successfully. Click 'Show Results' to display all objects found".
  • Click OK to close the message box and continue with the removal process.
Back at the main Scanner screen:
  • Click on the Show Results button to see a list of any malware that was found.
  • Make sure that everything is checked, and click Remove Selected.
  • When removal is completed, a log report will open in Notepad.
  • The log is automatically saved and can be viewed by clicking the Logs tab in MBAM.
  • Copy and paste the contents of that report in your next reply. Be sure to post the complete log to include the top portion which shows MBAM's database version and your operating system.
  • Exit MBAM when done.
Note: If MBAM encounters a file that is difficult to remove, you will be asked to reboot your computer so MBAM can proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware.

That link gives me a log-in page for g-mail.

Also, please answer my prior question: Were you experiencing any computer issues before this disk issue? If so, what were they?

Sorry about that, http://i1187.photobucket.com/albums/z382/Phellopia/geez.jpg
The computers desktop had vanished so the only way I found I was able to run programs was with the task manager, windows would not configure updates and the computer started to bluescreen on me. Now all it does is get to that screen and stay there.

Hello, that indicates Windows cannot read from your harddisk. It may indicate that malware has corrupted something, or that the disk itself has gone bad. To find out what it is, please follow the steps below.

Try this please. You will need a USB drive.

Download GETxPUD.exe to the desktop of your clean computer
  • Run GETxPUD.exe
  • A new folder will appear on the desktop.
  • Open the GETxPUD folder and click on the get&burn.bat
  • The program will download xpud_0.9.2.iso, and upon finished will open BurnCDCC ready to burn the image.
  • Click on Start and follow the prompts to burn the image to a CD.
  • Remove the USB & CD and insert it in the sick computer
  • Boot the Sick computer with the CD you just burned
  • The computer must be set to boot from the CD
  • Gently tap F12 and choose to boot from the CD
  • 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 the following and press enter:

    dd if=/dev/sda of=mbr.bin bs=512 count=1

  • Press Enter
  • After it has finished a file will be located on your USB drive named mbr.bin
  • Remove the USB drive and insert it back in your working computer and navigate to mbr.bin, zip it up and attach it to your next reply.

This will allow me to have a look at the MasterBootRecord of your drive and see if it is infected.

regards, Elise

Sorry, I should have realized you could not attach the file here.

Using xPUD, can you see the contents of the harddisk (sda1, sda2, and so on)?

regards, Elise

In that case lets have a look at the partition structure.
  • 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 & CD and insert it in the sick computer
  • Boot the Sick computer with the xpud CD.
  • The computer must be set to boot from the CD
  • Gently tap F12 and choose to boot from the CD
  • 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 your 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 Advanced and press Enter
    • Select [Boot] and press Enter
    • Select [Dump] and press Enter
    • Select [Quit] to exit
  • A log will be created in the root of the usb device
  • Remove the USB drive and insert back in your working computer

    Please note - all text entries are case sensitive
Copy and paste the resultant log for my review

regards, Elise
