Sound problem and driver problem

This is not likley to be related to malware and your logs are all clean. I will have you run two additional scans just to be safe but I do not expect it to find anything that would be the cause of this problem.


Goto the below link and follow the instructions for running TDSSKiller from Kaspersky

• TDSSkiller - How to run

Be sure to attach your log from TDSSKiller


Please also download MBRCheck to your desktop.


See the download links under this icon http://forums.majorgeeks.com/chaslang/images/MGDownloadLoc.gif

• Double click MBRCheck.exe to run (vista and Win 7 right click and select Run as Administrator)
• It will show a Black screen with some information that will contain either the below line if no problem is found:
  • Done! Press ENTER to exit...
• Or you will see more information like below if a problem is found:
  • Found non-standard or infected MBR.
  • Enter 'Y' and hit ENTER for more options, or 'N' to exit:
• Either way, just choose to exit the program at this point since we want to see only the scan results to begin with.
• MBRCheck will create a log named similar to MBRCheck_07.16.10_00.32.33.txt which is random based on date and time.
• Attach this log to your next message. (See: HOW TO: Attach Items To Your Post )

 

Okay MBRCheck does indicate potential problems with the MBR on two drives as shown below

Code:

 
     74 GB  [URL="file://\\.\PhysicalDrive0"]\\.\PhysicalDrive0[/URL]   Unknown MBR code
            SHA1: EC5B6F4B08268D5344F30BFF61C8B587F034795B
    232 GB  [URL="file://\\.\PhysicalDrive1"]\\.\PhysicalDrive1[/URL]   RE: Unknown MBR code

It is possible that this is just due to the way the Compac setup the partition to have a place to store a recovery partition but it is also very possible that it is really an infection. Repairing the MBR by replacing it with a valid Windows XP MBR is the only logical choice to be sure expecially since you are having problems with your PC. But do note that rewriting your non-standard MBR from Compac, could make future use of the Recovery Partition impossible which means you really do need a Windows XP boot CD so that you could reinstall from it if it every becomes necessary.


Questions:

1. Is the 232 GB drive an removal drive or is it a built in hard disk?
2. Do you have all of your important data backed up ( not backed up on either of these drives that is )? If not, you need to do that before continuing.
3. Do you have your Windows Boot CD which will be needed to repair your Master Boot Record?

 

I'm not really positive that your problems with sound are actually due to malware. Also not positive that your unknown MBR is really due to an infection. The only way to know would be to attempt fixing it and see what happens.

What I suggest is that you backup all of your important data first, then UNPLUG and leave unplugged the USB drive to only have your internal hard disk running.

Then since you say you do not have a Windows XP Boot CD, you will have to try something like below.

See what was posted in message # 12 of the below thread and see if you can get this CD to run.

whistler/black internet@mbr again!

Use it to fix the MBR on your hard disk and then boot back into normal Windows. See if your sound problems are fixed. Also re-run MBRcheck and attach the new log. Make sure that you do not plug the USB drive back into your PC until I tell you to do so.

 

Okay. Good luck.
