no sound- virus?

hi a little while ago i posted on the audio forums because the sound on my laptop stopped working (post:)

" hi recently i was having problems with ventrilo so i reinstalled my audio drivers and made sure they were up to date. After doing this i now have no sound on my
computer. under device manager the sound device is listed and is labeled as working, but in the taskbar there is a little speaker with a red "x" on it and when i right click
to open volume mixer it says "No audio device is installed" (even though there is one listed in device manager). ive tried both the newest version of the driver and the
driver than came already installed on my laptop (driver cd) with no effect.
specs:
audio device: SigmaTel High Definition Audio Codec
Laptop: Dell xps m1530
Vista: Home Premium 32bit"


eventually i called dell support and he wasn't sure what was wrong but suggested it may be do to a virus messing around with the registry and it may have corrupted a file or something to do with the drivers. i ran a virus scan and it found nothing. however before i reinstalled my drivers i've been getting a rundll error on start-up. its been happening for a while i've just ignored it because my comps been working fine. anyway the error happens every time on start-up and it says: rundll error unable to load wingzy32.rom, module cannot be found. is this because of a virus? and how do i remove it? i tried google but "wingzy32.rom" doesn't return any results.

thanks in advance

If you have a previous version of MBAM, remove it via Add/Remove Programs and download a fresh copy.

• Make sure you are connected to the Internet.
• Double-click on mbam-setup.exe to install the application.
• When the installation begins, follow the prompts and do not make any changes to default settings.
• When installation has finished, make sure you leave both of these checked:
  • Update Malwarebytes' Anti-Malware
  • Launch Malwarebytes' Anti-Malware
• Then click Finish.

MBAM will automatically start and you will be asked to update the program before performing a scan.

• If an update is found, the program will automatically update itself.
• Press the OK button to close that box and continue.
• If you encounter any problems while downloading the updates, manually download them from here and just double-click on mbam-rules.exe to install. Alternatively, you can update through MBAM's interface from a clean computer, copy the definitions (rules.ref) located in C:\Documents and Settings\All Users\Application Data\Malwarebytes\Malwarebytes' Anti-Malware from that system to a usb stick or CD and then copy it to the infected machine.

On the Scanner tab:

• Make sure the "Perform Quick Scan" option is selected.
• Then click on the Scan button.
• If asked to select the drives to scan, leave all the drives selected and click on the Start Scan button.
• The scan will begin and "Scan in progress" will show at the top. It may take some time to complete so please be patient.
• When the scan is finished, a message box will say "The scan completed successfully. Click 'Show Results' to display all objects found".
• Click OK to close the message box and continue with the removal process.

Back at the main Scanner screen:

• Click on the Show Results button to see a list of any malware that was found.
• Make sure that everything is checked, and click Remove Selected.
• When removal is completed, a log report will open in Notepad.
• The log is automatically saved and can be viewed by clicking the Logs tab in MBAM.
• Copy and paste the contents of that report in your next reply and exit MBAM.

Note: If MBAM encounters a file that is difficult to remove, you may be asked to reboot your computer so it can proceed with the disinfection process. Regardless if prompted to restart the computer or not, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware. MBAM may "make changes to your registry" as part of its disinfection routine. If using other security programs that detect registry changes (ie Spybot's Teatimer), they may interfere or alert you after scanning with MBAM. Please temporarily disable such programs or permit them to allow the changes.

edit: thanks! it worked got rid of the rundll error unfortunately sound isn't working still but at least this means it most likely isn't virus/malware related.

"No audio device is installed" (even though there is one listed in device manager)

remove, uninstall it and reboot

try rolling back the driver?
