Hello,

Currently one of my svchosts goes to 90-100% computer usage when ever there is some sort of sound played. Iv looked all of the other posts on here and nothing seems to help, but iv tried to windows restore/virus scan/ malwarescan and nothing =/. So if you guys could help it would be greatly appreciated.

I have SP2 xp pro
AMD Athlon 64 processor 3800+
2.0gb ram
nvidia geforce 9800gt

Search your hard drive for this file:

wscntfy.exe

Post back what you find.

That looks normal.

Have you tried reinstalling your sound driver?

See if this tutorial helps:

The tutorial shows a video driver, but the process is the same. Post back if you have any questions.

Please help :thumbsup:

That wscntfy.exe is the process that (when working properly) displays the shield in the Notification Area when the XP Security Center need attention, like turning off Automatic Updates for me gives me that process and a shield (you know the one).

It runs under svchost, but does not take hardly any CPU.

I don't think it should be running at all if things are set up "properly" or the one you have is afflicted - so do you have the Windows Security icon showing or not and is your SC configured properly? What if you change your SC settings?

Start, Settings, Control Panel, Security Center...

I would terminate that wscntfy process and/or the svchost and see how things look. Kill them both - it should not be running in the first place. It is a little hard to kill it and it will come back on its own but not under svchost.

You can keep Task Manager on top sorted by the CPU column, kill the svchost and/or wscntfy with PE and see what happens in TM.

I read that malicious software can disguise itself as wscntfy.exe, so you should do some scans:

Reduce the chances of malicious software by running some scans.

Download, install, update and do a full scan with these free malware detection programs:

Malwarebytes (MBAM): http://malwarebytes.org/
SUPERAntiSpyware: (SAS): http://www.superantispyware.com/

These can be uninstalled later if desired.

I run MBAM constantly, and i just did a new full scan and it found nothing.


Also I have the Updates turned off completely for Security center.

Well, you are one Service Pack behind and you said AU is turned off.

Why are you not on SP3 and why do you have AU turned off?

Do you have the shield in the Notification Area?

I don't think wscntfy.exe should be running at all if things are set up properly. It may not be your issue, but I just find it annoying since it is not running on my systems here - unless I disable parts of SC.

Did you try killing it?

XP had issues with Automatic Updates, svchost 100% CPU (and sometimes sound) that you can patch, or get SP3.

The two part patch is: http://support.microsoft.com/kb/927891

I am not saying that is for sure that is your issue, but installing the patch seems to have worked for others with similar symptoms and it is also rolled into SP3.

If you already have it installed you will have this folder: C:\windows\$NtUninstallKB927891$ or you can check the MS Update site for a list of your updates.

You can kill individual services under that svchost and perhaps zero in on which service it is. If it was me I would start with Security Center. If you kill something important, you may just have to reboot. Yous does not look exactly like mine of course.

Have you recently updated any HP related printer software?

In Process Explorer double-click on the svchost.exe that is using all the CPU and then click on the Threads tab. Can you identify which thread is using all the CPU?
