Booting up the machine in MS Windows Recovery Console, I got BSOD with Stop: 0x0000007B (0xF78D2524, 0xC0000034, 0x0, 0x0)

Hi,

1. Download Bootkit Remover (note: it's a RAR archived file so you have to install compatible program, like 7-Zip if there's not one installed).

2. Extract the contents to own folder (BRemover folder) on your desktop.

3. Click start->run->type cmd.exe and press enter.

4. In command prompt type this (I assume you extracted folder contents to BRemover folder on your desktop):

"%userprofile%\desktop\Bremover\remover.exe" >"%userprofile%\desktop\logit.txt"

5. Press enter once more to bring cursor back visible after entering the command above. After that operation there should be logit.txt file on your desktop. Attach it to your post, please.

Hi,

Attached is the log file from Bootkit remover.

Well congrats, it appears your system is all clean Are you still noticing any problems? If not, it's time to secure your system to prevent against further intrusions.

THESE STEPS ARE VERY IMPORTANT

Reset and Re-enable your System Restore to remove infected files that have been backed up by Windows. The files in System Restore are protected to prevent any programs changing those files. This is the only way to clean these files: You will lose all previous restore points which are likely to be infected. Please note you need Administrator Access to do clean the restore points.

1. Turn off System Restore.

On the Desktop, right-click My Computer.

Note: If you receive a warning from your firewall or other security programs regarding OTC attempting to contact the internet, please allow it to do so.

UPDATING WINDOWS AND INTERNET EXPLORER

IMPORTANT: You Need to Update Windows and Internet Explorer to protect your computer from the malware that is around on the Internet. Please go to the windows update site to get the critical updates.

If you are running Microsoft Office, or any portion thereof, go to the Microsoft's Office Update site and make sure you have at least all the critical updates installed (Free) Microsoft Office Update.

Make your Internet Explorer more secure

This can be done by following these simple instructions:

From within Internet Explorer click on the Tools menu and then click on Options.

The following are recommended third party programs that are designed to keep your computer clean. A link as well as a brief description is included with each item.

• hosts file:
  
  • Every version of windows has a hosts file as part of them.
    
  • In a very basic sense, they are used to locate webpages.
    
  • We can customize a hosts file so that it blocks certain webpages.
    
  • However, it can slow down certain computers.
    
  • This is why using a hosts file is optional!!
    

  Download it here. Make sure you read the instructions on how to install the hosts file. There is a good tutorial here

  If you decide to download the hosts file, the slowdown problems can usually be avoided by following these steps:

  1. 
     
     
  2. Click the start button (at the lower left hand corner of your screen)
     
  3. Click run
     
  4. In the dialog box, type services.msc
     
  5. hit enter, then locate dns client
     
  6. Highlight it, then double-click it.
     
  7. On the dropdown box, change the setting from automatic to manual.
     
  8. Click ok
     

  [*]Run Secunia vulnerability check here and fix its findings.

Just a final reminder for you. I am trying to stress these two points.

UPDATE UPDATE UPDATE!!! Make sure you do this about every 1-2 weeks.

Make sure all of your security programs are up to date.

Visit Microsoft's Windows Update Site Frequently - It is important that you visit http://www.windowsupdate.com regularly. This will ensure your computer has always the latest security updates available installed on your computer. If there are new updates to install, install them immediately, reboot your computer, and revisit the site until there are no more critical updates.

Once again, please post and tell me how things are going with your system... problems etc.
