My OS is win 7 Prof 64 bit and I ran the Malware Adware program to get rid of the spywares etc that had taken control of my pc.  After the run and clean up, I now have no sound.  How do I fix this now.  Thank u.

    Try running Combo Fix.  I know it sounds dumb, but it solves a lot of issues with messed up drivers after cleaning malicious stuff from your pc.

    Try to reinstall your sound driver. This will probably fix your problem.

    Along with the above, if you think the malware is cleaned up, run System File Checker. Open cmd.exe with Run as Administrator and run SFC /SCANNOW. Allow to complete and run again if errors remained. Restart the computer and check.

    If all the above does not work you can try a Windows Repair Install with the original DVD. You should back up your computer first, although the repair should leave your programs and data intact.

    Thank u everyone for your participation.  I tried xBouchardx's suggestion, using ComboFix, and it worked like a charm. It took quite some time to scan and also give the report.  I will post another Q to analyze the report so that u could advise if there are any remedial action that I should take.  Thank u for your suggestion, well done.

    Did you try System File Checker?  And don't forget Repair Install if everything else fails.

    >>  , using ComboFix, and it worked like a charm.   <<   do you have sound now?
    if not i recommend these :
    -check if the device is enabled in the bios
    -in device manager, check if the card is installed without errors
    -look if there are driver updates available, and install them
    -if needed, install / uninstall the  UAA HD Audio Bus driver
    -start>run>services.msc  and check if the Windows Audio service started and set to automatic?
            then, from Device Manager>view   click "show hidden devices" , now  right click your sound devices, and select Uninstall.
            Reboot, and cancel the wizard to reinstall
            Install your latest drivers, and reboot to complete the install......
    -in the audio and sound applet>audio tab check if the sound card is selected
    -in the volume section, check if the sound is turned up enough, and NOT muted
    -in the audio and sound applet>sounds tab select the start windows sound, and check if you can play it
    -check if the speakers are connected to the proper sound output (green)
    -test the speakers on another PC

    you can also use drivereasy to find and install your drivers :
