I just took care of some malware issues over at:

Thankfully, they are resolved. However, the last instructions that I was give was to run an administrator level sfc /scannow...

 

... and it returned this:

So there are corrupt files.. but it can't fix them, and it never asked me for the CD.  I ran it a second time with the CD already in the computer, but it made no difference.

 

It appears that the problem is related to "autochk.exe".  The log is too large to simply attach. (2.3 MB)

 

Thanks for any help.

Autochk.exe is part of chkdsk. It runs automatically on start up under certain situations. It's usually a good idea to run chkdsk after an sfc scan that finds certain errors or problems.

Did sfc prompt you to insert the CD during the scan? Inserting it before the scan won't make any difference if sfc doesn't "call" for the CD. Sfc won't fix some corrupt files if they aren't critical to startup or to basic system operation. You may need to do a repair operation from the CD in order to address this issue.

Hi

 

If SFC can't repair a corrupted file, your best option is to do a repair install. It will preserve all your data, program and settings while replacing all the core Windows files. Read the below guide to know how to do a repair install properly.

No, it never asked me for the CD.  I do not know what a repair operation is...

Sorry, I should have been clearer. Anshad left some nice instructions on how to do that. If you have the installation CD, you can run it from there, or from the recovery partition if you have one of those on your hard drive.
