I have run the aswMBR.exe file.  Attached is the log from it.  I did not do a fix MBR.  Should I run it again and do the fix even though it gives me a warning?

no fix yet....wait for essexboy

OK go Start > Run and copy/paste in the following command

%UserProfile%\desktop\aswMBR.exe -ap 2

Then press Enter

Reboot when asked and then re-run aswMBR

[chris312]

It tells me it cannot find "c:/documents"

[essexboy]

OK just use this part of the command

aswMBR.exe -ap 2

[chris312]

   It now tells me it can't find the file.  The aswMBR.exe file - even though I can browse right to it.  If I browse to the file, select it and attempt to add the -ap 2, it still tells me it can't find aswMBR.exe.

OK if this fails are you able to burn a CD as I will then need to kill it outside of windows



Download the latest version of TDSSKiller from here and save it to your Desktop.
 
 

• Doubleclick on TDSSKiller.exe to run the application
  
  
  
• Then click on Change parameters.
   
  
   
  
• Check the boxes beside Verify Driver Digital Signature and Detect TDLFS file system, then click OK.
   
  
• Click the Start Scan button.
   
   
  
• If a suspicious object is detected, the default action will be Skip, click on Continue.
   
  
   
  
• If malicious objects are found, they will show in the Scan results and offer three (3) options.
• Ensure Cure is selected, then click Continue => Reboot now to finish the cleaning process.
  
  
• Get the report by selecting Reports

 

• Note: If Cure is not available, please choose Skip instead, do not choose Delete unless instructed.
  

Please copy and paste its contents on your next reply.

Did that.  Report was too large to include in post. Am attaching text file of it.

[chris312]

Rebooted the computer. Now it will not come up at all! It keeps flashing, trying to load and turning off.  NOW WHAT?

[essexboy]

I notice from the log that you did not select cure for the MBR problem. Which would suggest that nothing was changed

 I need you to download:
gparted-live-0.10.0-3.iso (115.1 MB) 

Create a bootable CD, for Gparted from the ISO image.

You can use ImgBurn do this.

Now boot off of the newly created Gparted CD. 



You should be here... Press ENTER



By default, "do not touch keymap" is highlighted.
Leave this setting alone and just press ENTER. 



Choose your language and press ENTER. English is default [33]



Once again, at this prompt, press ENTER 
You will now be taken to the main GUI screen below



According to your logs, the partition that you want to delete is 2 MB

Click the trash can icon to delete and then click Apply.

You should now be here confirming your actions: 

 

Now you should be here:

 



Is "boot" next to your OS drive? 
If "boot" is not next to your OS drive under "Flags", right-mouse click the OS drive while in Gparted and select Manage Flags 

In the menu that pops up, place a checkmark in boot like the picture below:

 


Now double-click the button. 

You should receive a small pop up like this:
 

Choose reboot and then press OK.

Only problem is, the tdss killer "killed" my boot drive completely. The computer didn't even recognize it was there.  Problem has been solved. We took the drive out completely, reformatted it (using another computer), then restored the last Acronis backup onto the drive and an earlier MBR backup. Computer functioning now.

Thank the powers that be for Acronis!

Thanks for your help.

[essexboy]

Did you reset the Flag to the system drive ?

Yep a backup is always the best result
