Also in registry:
...control\SecurityProviders\msapsspc.dll, schannel.dll, digest.dll, msnsspc.dll, mcenspc.dll

in Event viewer - error from March 1, 2009

The protected system file userinit.exe could not be restored to its original, valid version. The file version of the bad file is unknown The specific error code is 0x800b0003 [The form specified for the subject is not one supported or known by the specified trust provider.
].

Also I get the error after starting the computer:

Application popup: MSTask.exe - Bad Image : The application or DLL C:\WINNT\system32\mcenspc.dll is not a valid Windows image. Please check this against your installation diskette.

Hello and welcome, I'll need a log from this scanner,thanks.

Next run MBAM:
Please download Malwarebytes Anti-Malware (v1.34) and save it to your desktop.
alternate download link 1
alternate download link 2
If you have a previous version of MBAM, remove it via Add/Remove Programs and download a fresh copy.
  • Make sure you are connected to the Internet.
  • Double-click on mbam-setup.exe to install the application.
  • When the installation begins, follow the prompts and do not make any changes to default settings.
  • When installation has finished, make sure you leave both of these checked:
    • Update Malwarebytes' Anti-Malware
    • Launch Malwarebytes' Anti-Malware
  • Then click Finish.
MBAM will automatically start and you will be asked to update the program before performing a scan.
  • If an update is found, the program will automatically update itself.
  • Press the OK button to close that box and continue.
  • If you encounter any problems while downloading the updates, manually download them from here and just double-click on mbam-rules.exe to install. Alternatively, you can update through MBAM's interface from a clean computer, copy the definitions (rules.ref) located in C:\Documents and Settings\All Users\Application Data\Malwarebytes\Malwarebytes' Anti-Malware from that system to a usb stick or CD and then copy it to the infected machine.
On the Scanner tab:
  • Make sure the "Perform Quick Scan" option is selected.
  • Then click on the Scan button.
  • If asked to select the drives to scan, leave all the drives selected and click on the Start Scan button.
  • The scan will begin and "Scan in progress" will show at the top. It may take some time to complete so please be patient.
  • When the scan is finished, a message box will say "The scan completed successfully. Click 'Show Results' to display all objects found".
  • Click OK to close the message box and continue with the removal process.
Back at the main Scanner screen:
  • Click on the Show Results button to see a list of any malware that was found.
  • Make sure that everything is checked, and click Remove Selected.
  • When removal is completed, a log report will open in Notepad.
  • The log is automatically saved and can be viewed by clicking the Logs tab in MBAM.
  • Copy and paste the contents of that report in your next reply and exit MBAM.
Note: If MBAM encounters a file that is difficult to remove, you may be asked to reboot your computer so it can proceed with the disinfection process. Regardless if prompted to restart the computer or not, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware. MBAM may "make changes to your registry" as part of its disinfection routine. If using other security programs that detect registry changes (ie Spybot's Teatimer), they may interfere or alert you after scanning with MBAM. Please temporarily disable such programs or permit them to allow the changes.

Yes any program i or any BC Mod or Advisor reccomends here has been tested safe.

Backing Up Your Registry
  • Go Here and download ERUNT
    (ERUNT (Emergency Recovery Utility NT) is a free program that allows you to keep a complete backup of your registry and restore it when needed.)
  • Install ERUNT by following the prompts
    (use the default install settings but say no to the portion that asks you to add ERUNT to the start-up folder, if you like you can enable this option later)
  • Start ERUNT
    (either by double clicking on the desktop icon or choosing to start the program at the end of the setup)
  • Choose a location for the backup
    (the default location is C:\WINDOWS\ERDNT which is acceptable).
  • Make sure that at least the first two check boxes are ticked
  • Press OK
  • Press YES to create the folder.
Registry Modifications

For more information about modifying the registry, see this Microsoft article: http://support.microsoft.com/default.aspx/kb/256986

Hi, I need to check this. The "No Action Taken"in your log generally means you did not click the "Remove Selected" button. If that's the case rerun MBAM and do so and post the log again.

Then run ATF and SAS.... I'll look back in the morning.

SAS
From your regular user account..
Download Attribune's ATF Cleaner and then SUPERAntiSpyware , Free Home Version. Save both to desktop ..
DO NOT run yet.
Open SUPER from icon and install and Update it
Under Scanner Options make sure the following are checked (leave all others unchecked):
Close browsers before scanning.
Scan for tracking cookies.
Terminate memory threats before quarantining
.
Click the "Close" button to leave the control center screen and exit the program. DO NOT run yet.

Now reboot into Safe Mode: How to enter safe mode(XP)
Using the F8 Method
Restart your computer.
When the machine first starts again it will generally list some equipment that is installed in your machine, amount of memory, hard drives installed etc. At this point you should gently tap the F8 key repeatedly until you are presented with a Windows XP Advanced Options menu.
Select the option for Safe Mode using the arrow keys.
Then press enter on your keyboard to boot into Safe Mode
.

Double-click ATF-Cleaner.exe to run the program.
Under Main "Select Files to Delete" choose: Select All.
Click the Empty Selected button.

If you use Firefox or Opera browser click that browser at the top and choose: Select All
Click the Empty Selected button.
If you would like to keep your saved passwords, please click No at the prompt.
Click Exit on the Main menu to close the program
.

NOW Scan with SUPER
Open from the desktop icon or the program Files list
On the left, make sure you check C:\Fixed Drive.
Perform a Complete scan. After scan,Verify they are all checked.
Click OK on the summary screen to quarantine all found items.
If asked if you want to reboot, click "Yes" and reboot normally.

To retrieve the removal information after reboot, launch SUPERAntispyware again.
Click Preferences, then click the Statistics/Logs tab.
Under Scanner Logs, double-click SUPERAntiSpyware Scan Log.
If there are several logs, click the current dated log and press View log.
A text file will open in your default text editor.
Please copy and paste the Scan Log results in your next reply.
Click Close to exit the program.


Please ask any needed questions,post log and Let us know how the PC is running now.

I removed with mbam and restarted the computer. After I again checked by mbam but still it found the same userinit.exe with problems. I think it can't resolve it.
As I mentioned in my first topic - I think userinit.exe was infected/modified by stu2.exe, I found in the internet about stu2.exe ( " Troj/Rootkit-EG copies itself to <System>\userinit.exe. It renames the original userinit.exe to stu2.exe." )

I don't know what the best way to resolve it. I know here somebody had such problem but I don't know how it was resolved.

Could you tell me, maybe I need to try to delete stu2.exe and old userinit.exe and add a right userinit.exe from somewhere? Thanks

Hi sorry I had posted an XP repair,then I needed to fid something for WIN 2000.
Do you have the install disks?
Do you have the path to "userinit.exe" The one being found.
Let's try removing stu2.exe with File Asassin

MBAM has a built-in FileAssassin feature for removing stubborn malware or other malicious files that it did not detect.

Go to the "More Tools" tab and click on the "Run Tool" button
Browse to the location of the file (C:\yrwmdmle.exe) to remove using the drop down box next to "Look in:" at the top.
When you find the file(s), click "Open".
You will be prompted with a message warning: This file will be permanently deleted. Are you sure you want to continue?. Click Yes.
If removal did not require a reboot, you will receive a message indicating the file was deleted successfully, however, I recommend you reboot anyway.


Caution: Be careful what you delete. FileAssassin is a powerful program, designed to move highly persistent files. Using it incorrectly could lead to serious problems with your operating system.



If the file returns, then you probably still have malware on your system which is protecting or regenerating it.
