Question about Microsoft Windows XP Professional

1 Answer

I believe I picked up a virus that has killed my sound

I picked up a virus a while back that modified some things in the registry. I've gotten everything fixed but one. It has disabled my sounds. I believe I have fixed everything but the sound issue. Basically its telling the computer that there is no audio device installed, even though in the device manager it picks up and understands there is a sound card installed, and states it is working fine. At first I thought it was the sound card, but after pulling it out and trying to use the built in card I realized it was a software issue. I need to know what I need to look for in the registry or where ever on my computer and see what is disabling my sound. My only other option is to format the drive and reinstall windows fully from scratch. And I rather not backup all of my data.

    Well that won't work since I built the computer back ten years ago. I'm just waiting on Income taxes so I can build a new one. Just rather not waste a lot of time trying to repair this one due to the hardware thats in it.

How about an easier solution? Go to your computer manufacturers website ->Support->Software and Driver downloads, and download the needed audio driver.

Then install the driver. Your audio driver is corrupted, this audio driver download will repair it.

    I understand. Now how about really learning to build computers?

    A Driver is software that allows 'communication' between a device and the O/S. (Operating System. Example: Windows XP)
    You can download the driver for FREE, from the motherboard manufacturers website. (Support>Software and Driver downloads)

    Your motherboard has a sound chip integrated on the board. The motherboard manufacturer has the driver/s for this sound chip.

Why is adobe flash player crashing everyday?


Quite often you may have to do the removal and restart your PC. Once you have done that, check your registry to make sure you have removed any traces of flashplayer. Before you edit your registry, make sure you back it up first. Should something go awry, you can go back and recover to the back up registry file. Also make sure you do one product removal at a time and check that the reinstall removed all pieces.

  • The computer is infected with a virus.

Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly.

    • HKEY_CLASSES_ROOT\.<file_name_extension>
    • HKEY_CLASSES_ROOT\<file_name_extension>file

How do i get rid of a W32.SillyFDC virus


The following instructions pertain to all current and recent Symantec antivirus products, including the Symantec AntiVirus and Norton AntiVirus product lines.
  1. Disable System Restore (Windows Me/XP).
  2. Update the virus definitions.
  3. Run a full system scan.
  4. Delete any values added to the registry.

For specific details on each of these steps, read the following instructions.

1. To disable System Restore (Windows Me/XP)
If you are running Windows Me or Windows XP, we recommend that you temporarily turn off System Restore. Windows Me/XP uses this feature, which is enabled by default, to restore the files on your computer in case they become damaged. If a virus, worm, or Trojan infects a computer, System Restore may back up the virus, worm, or Trojan on the computer.

Windows prevents outside programs, including antivirus programs, from modifying System Restore. Therefore, antivirus programs or tools cannot remove threats in the System Restore folder. As a result, System Restore has the potential of restoring an infected file on your computer, even after you have cleaned the infected files from all the other locations.

Also, a virus scan may detect a threat in the System Restore folder even though you have removed the threat.

For instructions on how to turn off System Restore, read your Windows documentation, or one of the following articles:

Note: When you are completely finished with the removal procedure and are satisfied that the threat has been removed, reenable System Restore by following the instructions in the aforementioned documents.

For additional information, and an alternative to disabling Windows Me System Restore, see the Microsoft Knowledge Base article: Antivirus Tools Cannot Clean Infected Files in the _Restore Folder (Article ID: Q263455).

2. To update the virus definitions
Symantec Security Response fully tests all the virus definitions for quality assurance before they are posted to our servers. There are two ways to obtain the most recent virus definitions:
  • Running LiveUpdate, which is the easiest way to obtain virus definitions.

    If you use Norton AntiVirus 2006, Symantec AntiVirus Corporate Edition 10.0, or newer products, LiveUpdate definitions are updated daily. These products include newer technology.

    If you use Norton AntiVirus 2005, Symantec AntiVirus Corporate Edition 9.0, or earlier products, LiveUpdate definitions are updated weekly. The exception is major outbreaks, when definitions are updated more often.


  • Downloading the definitions using the Intelligent Updater: The Intelligent Updater virus definitions are posted daily. You should download the definitions from the Symantec Security Response Web site and manually install them.

The latest Intelligent Updater virus definitions can be obtained here: Intelligent Updater virus definitions. For detailed instructions read the document: How to update virus definition files using the Intelligent Updater.

3. To run a full system scan
  1. Start your Symantec antivirus program and make sure that it is configured to scan all the files.

    For Norton AntiVirus consumer products: Read the document: How to configure Norton AntiVirus to scan all files.

    For Symantec AntiVirus Enterprise products: Read the document: How to verify that a Symantec Corporate antivirus product is set to scan all files.


  2. Run a full system scan.
  3. If any files are detected, follow the instructions displayed by your antivirus program.
  4. Delete the autorun.inf file from writeable removable devices, if necessary.
Important: If you are unable to start your Symantec antivirus product or the product reports that it cannot delete a detected file, you may need to stop the risk from running in order to remove it. To do this, run the scan in Safe mode. For instructions, read the document, How to start the computer in Safe Mode. Once you have restarted in Safe mode, run the scan again.


After the files are deleted, restart the computer in Normal mode and proceed with the next section.

Warning messages may be displayed when the computer is restarted, since the threat may not be fully removed at this point. You can ignore these messages and click OK. These messages will not appear when the computer is restarted after the removal instructions have been fully completed. The messages displayed may be similar to the following:

Title: [FILE PATH]
Message body: Windows cannot find [FILE NAME]. Make sure you typed the name correctly, and then try again. To search for a file, click the Start button, and then click Search.

4. To delete the value from the registry
Important: Symantec strongly recommends that you back up the registry before making any changes to it. Incorrect changes to the registry can result in permanent data loss or corrupted files. Modify the specified subkeys only. For instructions refer to the document: How to make a backup of the Windows registry.
  1. Click Start > Run.
  2. Type regedit
  3. Click OK.

    Note: If the registry editor fails to open the threat may have modified the registry to prevent access to the registry editor. Security Response has developed a tool to resolve this problem. Download and run this tool, and then continue with the removal.

  4. Navigate to the following registry subkeys:

    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
    HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders
    HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\Windows\"load"

  5. In the right pane, delete any values associated with the worm.


  6. Exit the Registry Editor.

Dvd dual layer


Hi, Had this problem once in XP Pro SP2 and tried so many remedies which did not correct it. Finally, I found out that my registry was modified by a malicious software (maybe a virus even). It would then possibly be: a modified registry value; a tweaking utility was applied (like Tweak-XP Pro or TweakUI), and/or an update or security software disabled/modified some default features. Of particular interest was the setting at this registry entry: HKEY_USERS\DEFAULT\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer I have attached a screenshot of the current settings/values of this particular entry. Of course, the usual precaution when modifying registry applies - backup, copy old values that you may revert if it does not work, etc.
