No sound

Hi
When I opened my audio player ( Foobar )… Avast found viaudio.sys infected. I know it’s not infected. I went to virus chest and restored the file. Now…I have no sound on my computer.
In control panel the sound and audio devices shows I have no audio device. In Device Manager, under device status it says " windows cannot start this hardware device because its configuration information ( in the registry ) is incomplete or damaged. ( code 19 )."
Can you please tell me what to do…How do I get my sound back?

I know it's not infected.
and you know how?

have you tested the file at www.virustotal.com ? if scanned before click new scan
post link to scan result here

and what malwarename does avast give the file?

I can’t find viaudio.sys anymore in Windows\System32\drivers. After I restored it I restarted my computer…I don’t know what happened.
Can I reinstall it? How do I do that?

Ok I reinstalled my sound driver and got again the same alert.
Here is the picture with the malware and the link from virustotal

I have foobar and avast for a long time and never had problems. What should I do?

I’m sorry I forgot about viaudios log : https://www.virustotal.com/en/file/8d210564079dca280b2d99f4e4278cc87b308ca65504c2d5c99a8902f51fee9e/analysis/1387544031/

Only avast finds it as a malware.
Ok I will do that

I have one more question please…I’m using avast 7 because I have an old PC
I have Intel Celeron 2.4
Windows Xp Sp2 and 768 memory

Can I put Avast 9? will it run on my computer? Because I keep reintalling the sound drive and after restart avast blocks it no matter what I do.

if you have a little patient… may take some hours
if you uploaded the file to avast lab, they will correct the detection

Hello,
it will be fixed in next stream update.
