Rootkit.Win32.TDSS.d on Vista

[pancakejohn]

Please consider updating to Windows Vista Service Pack 2 (SP2).

I would love to, unfortunately I am unable to do so. That leads me to my next question. When I try to install Vista SP2 it says

"Service Pack installation cannot continue
One or more system components that the service pack requires are missing. "

According to Microsoft knowledge base:

This problem occurs because system components that are required to install Windows Vista SP2 are not present on your computer.

However, a common reason for this problem is that vLite was used to customize the Windows Vista installation and some required system components were removed.

To resolve this problem, use genuine Microsoft software media to reinstall Windows Vista with Service Pack 1 and then install Windows Vista SP2.

This is strange because I was able to install SP1 when it came out no problem, but now it gives me this error message. I would really like to avoid reinstalling vista especially after all the work we went through cleaning up my infection. Please let me know if you know any ways around this problem although its not directly related to removing malware.

Thanks

Not really any ways around it, since you used Windows Vista Extreme Edition as customization.

It probably modified uxtheme.dll, and several other important DLLs.

Your customization might be messed up, but you can try the System File Checker.

Command Prompt command: sfc /scannow

SFC didn't work 

BUT...

After a little searching on the web I came across:

Code: [Select]

all you have to do is is start regedit, navigate to this registry value below.

HKEY_LOCAL_MACHINE\SOFTWARE\vLite

Then delete the entire vLite key from the registry. When you do this it should allow for the service pack to continue to install.

Simply deleting this registry key solved my problem of installing SP2 

Thanks for all your help.
