no sound

    My HP Pavilion laptop dv7-1247cl suddenly developed a "no sound" problem. It runs the Vista OS, 64-bit, and I'm using AVG9 Free and SuperAntiSpyware Free.

    Here's what happened: I was web-browsing about 2 weeks ago when a malicious attack popped up (masquerading as a "security scan"), which I stopped as quickly as I could. This "security" program embedded itself in my system tray (lower-right corner of the screen), and I couldn't exit it or get rid of it. So I re-started the computer (a geek-buddy of mine told me later that I shouldn't have done that as that "activated the new malware instructions in the registry"--his guess) and during the re-boot process I got a Vista pop-up warning that something in the startup routine had an unknown address (or something like that). I figured that it was this bogus security scan thing. When I denied it, IExplorer wouldn't start when I tried it, and SuperAntiSpyware didn't function properly (e.g. it wouldn't check for updates). And the fancy touchpad thing between the keyboard and the screen that controls sound (and other playback options) showed my sound as "muted" (red light), even though the speaker icon in the system tray on the screen said I did have sound. Those were the only problems I noticed. So I re-started the computer again, and this time I "allowed" the pop-up warning during boot-up, and sure enough, that bogus security scan started again (I stopped it again) and again I couldn't delete it from my system tray. I decided to do a System Restore to a restore point saved earlier that afternoon when I knew the sound system was working properly. When the restore process finished and restarted the computer, there was still no sound, but at least everything else seems to be working just fine.

    The button-indicator light on the touchpad now ALWAYS shows red/mute (should be white for sound "on"). The button itself seems to work OK, as I can touch it and toggle the tray icon (on the screen) between "mute" & "on" and the volume controls seem to work fine, but that button-indicator stays stuck on red. Control Panel diagnostics say everything is working properly, drivers up-to-date and everything. But the sound remains dead.

    My geek-buddy suggested the problem is "due to a rootkit or some other software corruption." (He's moving out-of-state, so he can't help me right now, but he highly recommended you guys.) He had me download and run MBAM, and when I did, it found and removed one HKEY-registry-Trojan thingy, and that was all (see log run on 2010-08-20). All subsequent scans I tried (using any scanning program) show no infection. I'm kind of a novice and there's a lot here I don't quite understand, but I'm trying to learn.

    I followed your READ-ME malware removal guide and am attaching the requested logs.

    Thank-you in advance for your help!

    Important Notice: A new version of SUPERAntiSpyware is available.
    • Please uninstall your current version (this is necessary).
    • Then download this SUPERAntiSpyware
    • Install this new version. It may tell you that you need to reboot to complete the installation. You must reboot at this time.
    • After the reboot, run SUPERAntiSpyware and immediately click the Check for Updates button to get more updates for the database.
    • Now run a new full scan of your system. And attach this log later.

    If you did not deliberately set this proxy yourself then please include it in the HJT fix below:

    Please disable all anti-virus and anti-spyware programs while we do the following (re-enable when you are finished):

    Run C:\MGtools\analyse.exe by double clicking on it (Note: if using Vista, don't double click, use right click and select Run As Administrator). This is really HijackThis (select Do a system scan only) and select the following lines but DO NOT CLICK FIX until you exit all browser sessions including the one you are reading in right now:
    After clicking Fix exit HJT.

    Now Copy the bold text below to notepad. Save it as fixME.reg to your desktop. Be sure the "Save as" type is set to "all files" Once you have saved it double click it and allow it to merge with the registry.


    Make sure that you tell me if you receive a success message about adding the above
    to the registry. If you do not get a success message, it definitely did not work.

    Run Ccleaner. Only use the Run Cleaner button. Do not run anything else on any other forms.

    Now run this:
    Using ESET's Online Scanner

    Let me know how things are running? I may not be able to fix your sound but you can visit the software forum to resolve that.

    Attach the new SAS log as well as the log from the ESET scan.

    Thank you very much, Kestrel. Sorry it took so long to get back to you; I worked through the steps as time allowed. I updated the SUPERAntiSpyware per your instructions (and also updated Ccleaner, before I ran that).

    I did receive a "success" message when I ran the regedit file, so it worked.

    Every step seemed to work as expected, EXCEPT:
    While I was running the ESET scanner, my computer powered itself off (battery low due to a bad connection at the power jack -- plugged in but not charging). I fixed the connector problem and the battery started to re-charge, and I logged back on and the scan resumed. At the time the thing shut off I saw that there was 1 "found threat" already showing, but it WASN'T there when it restarted. I don't know if that original "threat found" is one of the 2 that showed up on the resumed scan's log. Sorry if that screwed it up. Should I run it again?

    No change in the sound problem. I will go to the software forum as you suggest when we're done here.

    Yes, you can re-run the ESET scan, and also run this:

    Please also download MBRCheck to your desktop

    • 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 data on it
    • Right click on the screen and select > Select All
    • Press Control+C
    • Open a notepad and press Control+V
    • now please ATTACH that report to this thread

    Then...

    Now run the C:\MGtools\GetLogs.bat file by double clicking on it. Then attach the new C:\MGlogs.zip file that will be created by running this.

    I re-ran ESET scan last night (I got impatient), and no problems were found.

    Here are the MBRcheck and MGlogs reports.

    Download TDSSKiller from Kaspersky to your directly onto your Desktop

    • Now double click the TDSSkiller.exe file to run it ( if using Vista or Windows 7 do not double click on it but rather, right click and select Run As Administrartor. )
    • Allow the application to run if prompted by Windows or any security programs you have installed
    • It will start the scan and run rather quickly and will notify you of whether anything is found or not.
    • Follow the instructions to delete/quarantine if asks you what to do when if finds something.
    • Whether an infection is found or not, a log file should be created on your C: drive ( or whatever drive you boot from) in the root folder named something like TDSSKiller.2.1.1_27.12.2009_14.17.04_log.txt which is based on the program version # and date and time run. Please attach this log to your next reply. (See: HOW TO: Attach Items To Your Post )

    Let's see if MBRCheck will work.

    Please do the following:

    * Run MBRCheck.exe
    * Wait until you see the following lines:
    o Enter 'Y' and hit ENTER for more options, or 'N' to exit:
    o Options:
    [1] Dump the MBR of a physical disk to file.
    [2] Restore the MBR of a physical disk with a standard boot code.
    [3] Exit.
    Enter your choice:

    * Please push the 'Y' key and then press Enter
    * When the program asks you to Enter your choice: enter 2 to Restore the MBR and press the Enter key
    * Now the program will ask you to "Enter the physical disk number to fix (0-99, -1 to cancel):"
    o Enter 0 and press the Enter key.
    * The program will show Available MBR codes as below

    * You need to select your version of Windows from the list. For example, enter 0 or 1 for XP or enter 3 for Vista.....etc. and then press Enter.
    * The program will prompt for confirmation. Type 'YES' and hit Enter.
    * Left click on the title bar (where program name and path is written). From menu chose Edit -> Select All
    * You will see all the text in the window get highlighted.
    * Hit the Enter key on your keyboard to copy all of the text into the clipboard.
    * Paste that text into Notepad, save it to your desktop as MBRfix.txt
    * Restart your PC.
    * Attach the MBRfix.txt file to your next message..

    Now please re-run MBRCheck.exe and attach that log also.

    Yes, I did restart the computer. Twice--after each MBRcheck.

    The Microsoft service bulletin you linked to is for XP. I'm running Vista.

    I followed the link for burning the recovery disk and followed the successively linked instructions. I downloaded the Windows Vista 64-bit repair disk.torrent file, the uTorent.exe program and the ImgBurn program, all to my desktop. I am now burning the disk.
     
  12. TimW

    TimW MajorGeeks Administrator - Jedi Malware Expert Staff Member

    Let me know how that goes.
     
  13. retro-man

    retro-man Private E-2

    OK, I have burned the Recovery Disk and have it in hand. How do I use it?
     
  14. TimW

    TimW MajorGeeks Administrator - Jedi Malware Expert Staff Member

    You need to boot to the disc, which takes you into the Recovery Environment. From there you should have an option to go to the Command prompt, where you can enter the fixmbr command.
     
  15. retro-man

    I'm on another computer now so I can communicate while working on the one with the problem. I've booted to the Recovery Disk, and selected the "Repair your computer" option. I now see the option for the Command Prompt.

    The prompt says
    X:\Sources>

    entering "fixmbr" (without the quotes) doesn't work (not recognized).
     
  16. TimW

    TimW MajorGeeks Administrator - Jedi Malware Expert Staff Member

    Then the option should be the "repair your computer". Let me know how that goes.
     
  17. retro-man

    retro-man Private E-2

    OK, I just got home from work (it's 5:25 pm PDT). I 'm on another computer so I can communicate with you while we're working on the broken one.

    I just now booted to my Windows Vista 64-bit Recovery Disk, and selected "Repair your computer".
    I now have 5 "System Recovery Options":

    Startup Repair: Automatically fix problems that are preventing Windows from starting
    System Restore: Restore Windows to an earlier point in time
    Windows Complete PC Restore: Restore your entier server or personal computer from a backup image
    Windows Memory Diagnostic Tool: Check your computer for memory hardware errors
    Command Prompt: Open a command prompt window

    and 2 buttons at the bottom of the window for "Shut Down" and "Restart".

    Which one do I choose to fix the MBR? Or do I need to do something else?
     
  18. TimW

    TimW MajorGeeks Administrator - Jedi Malware Expert Staff Member

    I would first suggest that you choose option 1. That should re-write your MBR. After it runs and you are back up and running, re-run the MBRCheck so I can see if that worked.
     
  19. retro-man

    retro-man Private E-2

    OK, I ran the "Startup Repair" option and it ran its scan for problems but said it found no problems. Here is the new MBRcheck.

    Oops, sorry. I ran MBRcheck again, this time saying Yes, repair the bad code, (and re-booting). Here's the new report. Still no change.

    Please boot into the Recovery Environment. Then choose the Command Prompt.

    Next, type in:
    Bootrec.exe /fixmbr and hit enter. Then reboot into normal startup and re-run the MBRCheck to get a new log.

    Thank you, TimW.

    I followed your directions and immediately got the message: "The operation completed successfully." Here is the new MBRcheck log.

    The messages look promising ... but still no sound, and the touchpad button/light is still red.

    That did fix it. However your issues with sound and the touchpad may need to be addressed in the software forum. If you go into device manager are you seeing any X's or ?'s or !'s?

    Run the C:\MGtools\GetLogs.bat file by double clicking on it (Note: if using Vista, don't double click, use right click and select Run As Administrator).

    Then attach the below logs:

    * C:\MGlogs.zip

    So I can see if anything else is amiss.

    Great! Thank you.

    Yes, I found one ! warning in my Device Manager. I cut-n-pasted what it said to a text file (see attached).

    And here's the .zip file too.

    According to Microsoft, that is a common error and not significant:
    http://support.microsoft.com/kb/932520

    The only thing I see that you need to do is to run CCLeaner and empty our all your temp files.

    I suggest you post in the software forum for your sound issues.

    If you are not having any other malware problems, it is time to do our final steps:

    1. We recommend you keep SUPERAntiSpyware and Malwarebytes Anti-Malware for scanning/removal of malware. Unless you purchase them, they provide no real time protection. They do not use any significant amount of resources ( except a little disk space ) until you run a scan.We recommend them for doing backup scans when you suspect a malware infection.
    2. If we had you use ComboFix, uninstall ComboFix (This uninstall will only work as written if you installed ComboFix on your Desktop like we requested.)
      • Click START then RUN and enter the below into the run box and then click OK. Note the quotes are required
      • "%userprofile%\Desktop\combofix" /uninstall
        • Notes: The space between the combofix" and the /uninstall, it must be there.
        • This will uninstall ComboFix and also reset hidden files and folders settings back to Windows defaults.


    3. Go back to step 6 of the READ ME and renable your Disk Emulation software with Defogger if you had disabled it.
    4. Any other miscellaneous tools we may have had you install or download can be uninstalled and deleted.
    5. If we had you download any registry patches like fixme.reg or fixWLK.reg (or any others), you can delete these files now.
    6. If running Vista, it is time to make sure you have reenabled UAC by double clicking on the C:\MGtools\enableUAC.reg file and allowing it to be added to the registry.
    7. Go to add/remove programs and uninstall HijackThis.
    8. Goto the C:\MGtools folder and find the MGclean.bat file. Double click on this file to run this cleanup program that will remove files and folders related to MGtools and some other items from our cleaning procedures.
    9. If you are running Win 7, Vista, Windows XP or Windows ME, do the below:
      • Refer to the cleaning procedures pointed to by step 7 of the READ ME
        for your Window version and see the instructions to Disable System Restore which will flush your Restore Points.
      • Then reboot and Enable System Restore to create a new clean Restore Point.

    10. After doing the above, you should work thru the below link:

    OK, Thank you SO much, TimW! (And also thanks to Kestrel13! for getting me started.)
    I ran the CCleaner and will work through the "final steps" as time allows.
    Now I'm off to the Software Forum to address that touchpad issue (is there a proper name for that thing?). I'll let you know when it's finally fixed, if you'd like.
