I've only seen this error type once before - and it turned out to be the result of a ZeroAccess infection, as I was later told.

I think that you'd best scan for malware first.

Please download and install Malwarebytes Anti-malware (free version) from http://www.malwarebytes.org/products/malwarebytes_free/ - UNtick 'Enable free trial of MBAM PRO' at the end of the installation - and update it, then run a full scan in your main account, and Quick scans in any other user accounts.

Delete everything it finds

OK - Looking through the logs again, I noticed something I didn't see before...

I think I'd better take a close look at your COMPONENTS registry hive.

Please copy the C:\Windows\System32\config\COMPONENTS file (no extension) to your desktop and then compress it - upload the compressed file to your favoured fileshare site (preferably Dropbox or OneDrive) and post a link.

If the file won't copy (saying file in use), reboot to Safe Mode, and try there - it may be too damaged to complete loading.

Ooops! - good point.

Please run a new SFC and CheckSUR and we'll take a look at the entire CBS folder afterwards - it'll give us some detailed info.
