Blue Screen + Bad Pool error [Solved]

Lets try it this way.

DO NOT use any TOOLS such as Combofix or HijackThis fixes without supervision.

Doing so could make your pc inoperatible and could require a full reinstall of your OS, losing all your programs and data.

Vista and Windows 7 users:
1. These tools MUST be run from the executable. (.exe) every time you run them
2. With Admin Rights (Right click, choose "Run as Administrator")

Stay with this topic until I give you the all clean post.

You might want to print these instructions out.

I suggest you do this:

XP Users


Double-click My Computer.
Click the Tools menu, and then click Folder Options.
Click the View tab.
Uncheck "Hide file extensions for known file types."
Under the "Hidden files" folder, select "Show hidden files and folders."
Uncheck "Hide protected operating system files."
Click Apply, and then click OK.


Vista Users

To enable the viewing of hidden and protected system files in Windows Vista please follow these steps:

Close all programs so that you are at your desktop.
Click on the Start button. This is the small round button with the Windows flag in the lower left corner.

Click on the Control Panel menu option.
When the control panel opens you can either be in Classic View or Control Panel Home view:

If you are in the Classic View do the following:
Double-click on the Folder Options icon.
Click on the View tab.


If you are in the Control Panel Home view do the following:

Click on the Appearance and Personalization link.
Click on Show Hidden Files or Folders.
Under the Hidden files and folders section select the radio button labeled Show hidden files and folders.
Remove the checkmark from the checkbox labeled Hide extensions for known file types.
Remove the checkmark from the checkbox labeled Hide protected operating system files.


Please do not delete anything unless instructed to.

Please don't attach the scans / logs, use "copy/paste". .

The computer is working ok. It's fast and not crashing but I still get the random windows, Sitemeter still doesn't work and neither do graphics on some sites.

Just as I navigated away from this site I had this random window appear. According to Google, Directrdr is a malware carrier.

http://www.directrdr...m....html&mm=11

O3 - Toolbar: (no name) - {CCC7A320-B3CA-4199-B1A6-9F516DD69829} - (no file)

You can fix that one if you want.

Try this:
I suggest you do this:

Uninstall Internet Explorer 8 to return to Internet Explorer 7 on Windows XP

Click "Start," and then click "Control Panel."
Click "Add or Remove Programs."
Check "Show Updates" at the top of the dialog box.
Scroll down the list and highlight the version of Internet Explorer 8 that you are running, and then click "Change/Remove."

I did that this morning before I posted on here. Someone else suggested that.

It didn't work

MSIE: Internet Explorer v8.00 (8.00.6001.18702)


Download ComboFix from one of these locations:

Link 1
Link 2 If using this link, Right Click and select Save As.


* IMPORTANT !!! Save ComboFix.exe to your Desktop

• Disable your AntiVirus and AntiSpyware applications, usually via a right click on the System Tray icon. They may otherwise interfere with our tools. Note: If you are having difficulty properly disabling your protective programs, or are unsure as to what programs need to be disabled, please refer to the information available through this link : Protective Programs
  
  
• Double click on ComboFix.exe & follow the prompts.
  
  Notes: Combofix will run without the Recovery Console installed. Skip the Recovery Console part if you're running Vista or Windows 7.
  
  Note: If you have SP3, use the SP2 package.If Vista or Windows 7, skip the Recovery Console part
  
• As part of it's process, ComboFix will check to see if the Microsoft Windows Recovery Console is installed. With malware infections being as they are today, it's strongly recommended to have this pre-installed on your machine before doing any malware removal. It will allow you to boot up into a special recovery/repair mode that will allow us to more easily help you should your computer have a problem after an attempted removal of malware.
  
• Follow the prompts to allow ComboFix to download and install the Microsoft Windows Recovery Console, and when prompted, agree to the End-User License Agreement to install the Microsoft Windows Recovery Console.

**Please note: If the Microsoft Windows Recovery Console is already installed, ComboFix will continue it's malware removal procedures.

Once the Microsoft Windows Recovery Console is installed using ComboFix, you should see the following message:




Click on Yes, to continue scanning for malware.

When finished, it shall produce a log for you. Please include the C:\ComboFix.txt in your next reply.


Notes:

1.Do not mouse-click Combofix's window while it is running. That may cause it to stall.
2. ComboFix may reset a number of Internet Explorer's settings, including making I-E the default browser.
3. Combofix prevents autorun of ALL CD, floppy and USB devices to assist with malware removal & increase security. If this is an issue or makes it difficult for you -- please tell your helper.
4. CF disconnects your machine from the internet. The connection is automatically restored before CF completes its run. If CF runs into difficulty and terminates prematurely, the connection can be manually restored by restarting your machine.

Give it atleast 20-30 minutes to finish if needed.


Also please describe how your computer behaves at the moment.

Should I un-install IE8 and go back to IE6 before I run this?

Should I un-install IE8 and go back to IE6 before I run this?

No

Back again.

I've run ComboFix but I didn't get a txt file and I can't find one on the C drive either. I did notice that my C drive has renamed itself to ComboFix though. Is that right?

Also when ComboFix started to close windows after the 50 stage scan I got a blue scree for a few seconds. Just caught Bad Pool Header before it vanished.

What do I do next?

C drive has renamed itself to ComboFix though. Is that right?

No that isn't normal.
Reboot and see if you can find combofix.txt

No. Can't find it but I did get this:

I was also given a choice of booting to the Windows recovery Console or to the default Windows XP Home as the machine was re-booting.

Edited by Harriers9, 06 February 2010 - 03:25 PM.

I don't think that's from an infection.
I suggest you start a new topic in the windows forum and post your last post from here with that screen shot.

After you get that fix come back here and let me know how it's running.

Posted on there but no response yet.

Did a Highjack this again and that unknown toolbar is still there:

No File No Name so don't worry about that. The bad pool header issue needs fix before doing anything else. That's what's causing you to see 3 or 4 Local Disk C:
