    Hi, I encountered the above error after installing some programs::

     

    The symtoms: can't open control panel

     

    Software that i installed recently: PC tools Antivirus, Comodo firewall, AVG antivirus, Vista Codec

     

    I uninstalled all the above antivirus and firewall programs and tried to perform SFC but the error still persisted.

     

     

    Any help would be much appreciated,

     

    Thank you.

    Hello

     


    Vista is in, what is called a 'Mod-Auth' Tamper state.  There are 2 types of Mod-Auth tampers.

     

    1) A critical system file was modified On Disk - What this means is that the file, located on the hard drive, was modified in some way. This can be caused by random file corruption, a malicious program (spyware, malware, virus) or by manual file modification (by a user of the system). There is also a very small chance that an Update may fail in mid-update and cause this type of issue. As a safety mechanism, Updates are made so that if they fail, they roll back any updating that was done before the failure, but there is an off-chance that the roll back did not occure.

     

    2) A critical system file was modified In Memory - What this means is the file itself (on the hard drive) is un-modified, but the code, from that file, running in the system, was modified in some way. and is usually caused by a running program that is incompatible with Vista.

     

    Because there is no Mismatched files listed under the "File Scan Data-->" line of your Diagnostic Report, I beleive your issue is an In Memory Mod-Auth.

     

     addition to why a Tamper occurs, it's also important to understand how Vista detects the Tamper event. There is a Service that runs in Vista that detects a Tamper to a Critical System file. But this Service runs randomly, so if you were to install an incompatible program and run it, Vista (most likely) would not immediately enter a Tamper State and it could take some time for the Tamper to be detected. The important point to note is that the moment Vista detects the Tamper, you know that the program that caused the tamper, is currently running.

    Below I have provided a number of steps to help you identify the program that is causing the tamper:
     
      First, go to http://support.microsoft.com/kb/931699/ and confirm that you do not have any of the programs known to cause this type of issue.
     
      Second, in your Diagnostic report above, you can see the line that starts with 'TTS Error:' followed by a bunch numbers: M:xxxxxxxxxxxxxxxxx- This is the Tamper Time Stamp and it breaks down like this:

        (year)  (month) (day) (time in 24format) (millisecond)
    M:2008      01        25        1418                 13824


    Now that you know the time of the tamper, you can now try to connect that time with a program.

    1) Login to Vista and select the option that launches an Internet Browser

    2) Type into the browser address bar: %windir%\system32\perfmon.msc and hit Enter

    3) When asked if you want to Open or Save this file, select Open

    4) In the left hand panel, click Reliability Monitor

    5) Click on the “System Stability Chart” above the date 01/25

    6) Below the chart, in the “System Stability Report” section look at the report titled "Software (Un)Installs for 01/25/2008"

    7) Look for any program that shows "Application Install" in the 'Activity' column.

    8) Since the process that detects Tampers runs randomly, it can take up to 3 days for the process to detect the tamper and set Vista to a Tamper State. Because of this, please repeat steps 5) thru 7) for the dates 01/24/2008, 01/23/2008 and 01/22/2008

      This could tell us what programs were installed on or around the Tamper date and should help you  narrow down the possible programs that could be causing the issue . Unfortunately, if you installed the program (say) on 09/01/2007, but you didn't run (and, hence, prompted the tamper state)  till 01/25/2008, this process may not be helpful.  The removal of any application you may have installed recently could go a long way to troubleshooting this issues as well since it may fall outside of the 3 day time frame described above.

     

    Thank you,

    Hello

     


    Vista is in, what is called a 'Mod-Auth' Tamper state.  There are 2 types of Mod-Auth tampers.

     

    1) A critical system file was modified On Disk - What this means is that the file, located on the hard drive, was modified in some way. This can be caused by random file corruption, a malicious program (spyware, malware, virus) or by manual file modification (by a user of the system). There is also a very small chance that an Update may fail in mid-update and cause this type of issue. As a safety mechanism, Updates are made so that if they fail, they roll back any updating that was done before the failure, but there is an off-chance that the roll back did not occure.

     

    2) A critical system file was modified In Memory - What this means is the file itself (on the hard drive) is un-modified, but the code, from that file, running in the system, was modified in some way. and is usually caused by a running program that is incompatible with Vista.

     

    Because there is no Mismatched files listed under the "File Scan Data-->" line of your Diagnostic Report, I beleive your issue is an In Memory Mod-Auth.

     

     addition to why a Tamper occurs, it's also important to understand how Vista detects the Tamper event. There is a Service that runs in Vista that detects a Tamper to a Critical System file. But this Service runs randomly, so if you were to install an incompatible program and run it, Vista (most likely) would not immediately enter a Tamper State and it could take some time for the Tamper to be detected. The important point to note is that the moment Vista detects the Tamper, you know that the program that caused the tamper, is currently running.

    Below I have provided a number of steps to help you identify the program that is causing the tamper:
     
      First, go to http://support.microsoft.com/kb/931699/ and confirm that you do not have any of the programs known to cause this type of issue.
     
      Second, in your Diagnostic report above, you can see the line that starts with 'TTS Error:' followed by a bunch numbers: M:xxxxxxxxxxxxxxxxx- This is the Tamper Time Stamp and it breaks down like this:

        (year)  (month) (day) (time in 24format) (millisecond)
    M:2008      01        25        1418                 13824


    Now that you know the time of the tamper, you can now try to connect that time with a program.

    1) Login to Vista and select the option that launches an Internet Browser

    2) Type into the browser address bar: %windir%\system32\perfmon.msc and hit Enter

    3) When asked if you want to Open or Save this file, select Open

    4) In the left hand panel, click Reliability Monitor

    5) Click on the “System Stability Chart” above the date 01/25

    6) Below the chart, in the “System Stability Report” section look at the report titled "Software (Un)Installs for 01/25/2008"

    7) Look for any program that shows "Application Install" in the 'Activity' column.

    8) Since the process that detects Tampers runs randomly, it can take up to 3 days for the process to detect the tamper and set Vista to a Tamper State. Because of this, please repeat steps 5) thru 7) for the dates 01/24/2008, 01/23/2008 and 01/22/2008

      This could tell us what programs were installed on or around the Tamper date and should help you  narrow down the possible programs that could be causing the issue . Unfortunately, if you installed the program (say) on 09/01/2007, but you didn't run (and, hence, prompted the tamper state)  till 01/25/2008, this process may not be helpful.  The removal of any application you may have installed recently could go a long way to troubleshooting this issues as well since it may fall outside of the 3 day time frame described above.

     

    Thank you,
