SFC can't fix Tunmp.sys

[Muskiness3709]

Hello I have a working pc and cleared out many viruses. No signs of problems now. I ran chkdsk successfully. Everything works, except two things:

1). Windows Defender won't start and doesn't exist. On startup shows:
"Error Code 0x800106ba"
When I tried setting it to automatic in Services, or tried starting it by hand, it shows 'Error: 126 failed to start module'.

I also tried this:
http://support.microsoft.com/kb/931849
(Skip to the resolution step 3)
I was able to successfully input some of the files,
But I received this error : "The module failed to load. The specified module could not be found"
for the files:
wucltui.dll, wuweb.dll, initpki.dll.


2). Whenever I run SFC /Scannow, it cannot fix repairs and each time the log reports the same problem, something to do with Tunmp.sys

The CBS log is attached.

Welcome
Go to search type device manager. Look for any small yellow warning markers in device manager. If none:

Make a repair install.

Tunmp is a Microsoft Driver.

If you cannot do a repair install this may work

If you are using Microsoft Security Essentials, Defender is suppose to be off.
