Windows 7: Windows Update - total failure. TrustedInstaller.exe ==> 25% CPU.

Windows Update - total failure. TrustedInstaller.exe ==> 25% CPU.

Hi

I had a virus/trojan, but now it seems I am in the clear security wise.
How can I be sure if I am still infected with "Win32/Small.CA" virus".

Jacee was helping me with security issues but I think I have exhausted her skills.

But now I cant get Window Update to work at all. I have tried this Mr Fixit, which admits that there is a problem but fails to solve it.
How do I reset Windows Update components?

One clue is that TrustedInstaller.exe is running all the time, hogging about 25% of my CPU.

I searched for Reliability on my Start button and it took me to a place called:
"Control Panel\All Control Panel Items\Action Center\Problem Reports"
I then tried to delete everything but I can see that I am getting a vast number of "WindowsWcpOtherFailure3" problems - they are coming in every couple of seconds in fact.
Here is one of these problems in more detail:
Problem signature
Problem Event Name: WindowsWcpOtherFailure3
OsVersion: 6.1.7601
File: base\lstring\lblob.cpp
Function: RtlTranscodeLBlobs
Line: 2221
Status: c0000161
StackHash: 0xe2a94a52
OS Version: 6.1.7601.2.1.0.256.48
Locale ID: 2057
Extra information about the problem
Bucket ID: 1947205397

Out of desperation I have uninstalled everything I dont really, really need including Skype.

If I try to run Windows Update, after a very long time (2 minutes?) I eventually get an error message.

Also if I click on Installed Updates, it claims that there arent any on my PC. This is clearly nonsense - I have had my PC (running Windows 7 x64 for about 1 year now and there have been innumerable updates).

Can anyone help??

Many thanks

J

This is actually pretty normal under certain circumstances - TrustedInstaller has access to the system that no other parts do, and will run at a high priority.
It's in use when checking for updates, installing updates, and cleaning up - as well as when doing system maintenance.
What is unusual is that it's limited to a single processor, rather than utilizing more.

I can't find any mention of your having run any SFC scan, or CheckSUR scan lately?? - or even a chkdsk?


Please run a full CHKDSK and SFC scan....

Click on Start > All Programs > Accessories
Right-click on the Command Prompt entry
Select Run as Administrator and accept the UAC prompt - the Elevated Command Prompt window should pop up.

At the Command prompt, type

CHKDSK C: /R

and hit the Enter key.
You will be told that the drive is locked,
and the CHKDSK will run at he next boot - hit the Y key, and then reboot.

The CHKDSK will take a few hours depending on the size of the drive, so be patient!

After the CHKDSK has run, Windows should boot normally (possibly after a second auto-reboot) -
then run the SFC.

SFC -System File Checker - Instructions
Click on Start > All Programs > Accessories
Right-click on the Command Prompt entry
Select Run as Administrator and accept the UAC prompt - the Elevated Command Prompt window should pop up.

At the Command prompt, type

SFC /SCANNOW

and hit the Enter key

Wait for the scan to finish - make a note of any error messages - and then reboot.


Copy the CBS.log file created (C:\Windows\Logs\CBS\CBS.log) to your desktop (you can't manipulate it directly) and then compress the copy and attach it to your reply



Please download the CheckSUR tool from http://support.microsoft.com/kb/947821
(you'll need to look in the details for Method 2)
Run it from the saved download.
Then zip the CheckSUR.log and attach it to your reply

The tool can take anywhere from 5 mins to a couple of hours to run (or 'Install') depending on how much it has to do, and may exit silently - it may appear to freeze for most of that time, but be patient.

I ran the CHKDSK okay (I think - I am now away for a few days so am having to do it remotely...)

SFC WONT RUN
But I even though I ran it as Administrator, and even thought the initial message is
"Beginning systems scan. This process can take some time."
I cant run SFC because if give the error message:
"Windows Resource Protection could not preform the requested operation"

DAMN Windows. OKay I managed to get a command prompt to start called
"Adminsitrator: Command Prompt" and to show the default director to be
"C:\windows\system32" (which I am assuming to be what people call "an elevanted command prompt" ...But I a still getting the same error messages as above.

Any suggestions?

P.S. I have taken SO long trying to fix this problem that I am now having to work remotely. So please do NOT ask me to do anything that requires dirt-work access (such as insert a CD or press F8 to get access to Safe Mode!)

Bother - I was about to suggest an offline SFC, which can't be done remotely.

Never mind....
one thing that may give us some more data is an MGADiag report....

Please follow this tutorial and post an MGADiag report - then we can see what the problem is.

Please also state the Version and Edition of Windows quoted on your COA sticker (if you have one) on the case of your machine (or inside the battery compartment), but do NOT quote the Key on the sticker!

Ignore errors produced when clicking on the Copy button - they simply mean that the tool could not create the backup files for some reason. The data is still copied to the clipboard for pasting to your response.

Looks to me like you have some bit-flipping going on there - Tom is the expert on that, so I'll give him a shout.

Hi Shiphen, me again!

It's very odd that you're having registry corruptions again. No one should get file corruptions, especially at this kind of level. How long have you had your computer? I would've hinted that your HDD was failing, but seeing as CHKDSK reported no errors, I guess that isn't the case. If you're interested Noel, here's the thread:

Windows Update failing with Error codes: 8007371B, 800736B3, 80070246

Could you upload your components hive again please? Like we did last time.

C:\Windows\system32\config\COMPONENTS

I don't know whether those files are actually corrupt or not at this stage, so I'll take a look at your hive and get back to you

No need to apologise Find the file, copy it to your Desktop, right click > send to > compressed zipped folder. Then attach this to your next post by clicking on the paperclip icon in the reply box.
