Security Issue with Vista's 'Audio Endpoint builder'

Hello. I was tracking down why my *svhost.exe* (used for internet &

network Connections) was being used to access a whole bunch of Picture

files in one of my folders. Files that were not being used by any other

program or service at the time (not even the File Manager). It was

running _under_LocalSystemNetworkRestricted_mode_ and i tracked the PID

to the "'-Windows Audio Endpoint builder-' (http://tinyurl.com/6nbez6)"

Service. I used the resource monitor to see that the WAEB was accessing

numerous files in various folders.

_What_stood_out_was_my_personal_pictures_it_was_accessing_.

I looked the service up and in no way is it dependant on or is depended

on by any system except AUDIO on the computer. However according to a

company that deals in computer security (and Microsoft) it is a service

launched by the legitimate 'C:\Windows\System32\svchost.exe' program.

The actual executable file for the Windows Audio Endpoint Builder

service is 'C:\Windows\System32\audiosrv.dll'.

Now this 'service' was reading my picture (JPG) files in the Public

folder that has no system files in it. *Can anyone explain why an Audio

Support DLL is interested in my Pictures?* As well as other files.

I saw mention of this service having something to do with the System

Indexing Serice as well in my search results when trying to find

information. If it is related to indexing then why is it interested in

NON-AUDIO files at all? if the indexer uses 'Associated With'

executables to 'read' files for indexing then it should be using an

audio processor to deal with audio files and an image processor for

pictures, etc -- right?

My concern is that it is being used as a backdoor or such to

_grab_files_for_a_third_party_. Though I cannot find that this file

sends data beyond my machine, it may process it for another program

which would. As yet i cannot find anything suspicious on the outgoing

side.

Any Thoughts or comments would be appreciated.

THANK YOU
