Getting the Infamous "An unauthorized change has been made to windows" error RRS feed

  • Question

  • Hello-

    I realize there are several threads out there regarding this same error, but a few of my circumstances are different from those that users have posted so I thought I would start a new topic.  My computer is in a pretty sorry state, so some help would be much appreciated!

    First, a few facts:

    1) When I try to boot Windows (Vista Home, 32 bit) I get the aforementioned "unauthorized change" message
    2) I'm 80% sure this was caused by some malware that my system was infected with.  If it was not caused by the malware, it was almost certainly caused by the programs I used to remove the malware (Symantec, Adaware, Malbytes).
    3) A series of seemingly unrelated problems occured during my cleanup attempts, leading me to believe the Trojan that I was/am infected with (Win32 Trojan.Tdss was the first, others seemed to follow) was mucking things up nicely.  Among these were a COM Surrogate error and a Run32DLL (?) something or other error. 
    4) When I try to run "Repair my computer" or whatever the option is under F8, I get a fatal system crash.
    5) When I run Safemode, no taskbar appears at the bottom, however, I am able to pull things up by executing some commands through the Task Manager. 
    6) I've run the diagnostic tool several times with seemingly different results.  I'll paste the most recent results below.  It seems to indicate that my version is genuine (it is), but still has issues.
    7) The MS Onecare online scan does not work on my system.  I get the 0x0C600C03 error.  No idea why!
    8) I got the notion that somehow my install of Symantec might be causing some of these issues, but I cannot uninstall it from safemode.  I get an error indicated that the "Windows Installer Service cannot be accessed".
    9) I also tried to install IE8 during this time (in the hopes the security was more advanced) and it crashed during install.  I have yet to be able to install it.

    As you can see, things are very ugly!  Here are the MGADT scan results:

  • Hello JoePye,

    The core of your issue centers on the line in your Diagnostic Report that reads:

    File Scan Data-->
    File Mismatch: C:\Windows\system32\Slsvc.exe[6.0.6001.18000]

     

    This means the file has been Tampered, Modified or has become Corrupt. Vista see this as an attack to bypass it's Licensing security.


    (I think you are correct about the Malware causing the problem.)

    To resolve the issue, you need to either repair or replace the file with a known-good one (of the proper file version)

     

    First try repairing Windows using System Restore:

    1)    Reboot Vista into Safe Mode

    2)    Go to Control Panel

    3)    On the left hand side of the Control Panel window, Click on "Classic View"

    4)    Double-click "Backup and Restore Center"

    5)    On the left hand side of the window, click "Repair Windows using system restore"

    6)    Select "Choose Different Restore Point", Put a check in the box that says "Show restore points older than 5 days", select the restore point that corresponds to the date Before you first noticed the issue.

    7)    Click the "Next" button.

    8)    Reboot back into Normal mode

    9)    Vista should no longer be in Reduced Functionality mode

     

    If that doesn't work, we'll try doing a System Scan. The scan will look for bad Vista files and will attempt to repair them, if possible.

    1)    Login to Vista in Normal Mode (not safe mode)

    2)    Launch an Internet Browser

    3)    Type: %windir%\system32\ in the browser's address field

    4)    Scroll down till you find the file cmd.exe

    5)    Right-click the file and select 'Run as Administrator'

    6)    In the CMD window, type: sfc /scannow

    7)    Reboot twice and see if that resolves the issue.

    If neither of these sets of steps resolves the issue, my only other suggestions would be either to contact Vista support at http://support.microsoft.com or reinstall Vista.

    Thank you,
    Darin MS
