KB2919355 Fails to install on Server 2012 R2 with error 80071A2D

Question

I have several Server 2012 R2 installs that I just cannot get KB2919355 installed on.
I have tried via WSUS and also manually and in all cases, the update takes a while says a reboot is a required then on the restart it rolls back as the update fails.
I have tried running sfc /scannow which reports no issues.
I have also tried running dism /online /cleanup-image /restorehealth which reports corruption was repaired, however in the Windows Setup log it says "System store corruption detection and repair has completed. Status : 0x0, Total instances of corruption
found : 0, total instances of corruption repaired : 0
I take this to mean these components are healthy.
I'd really appreciate a few suggestions here as I'm kind of at a brick wall now. I can't think of anything else to try.
Looking through the Application log, I have a number of Windows Error Reporting entries, most of which don't really say much but one does point to attached files including c:\windows\inf\setupapi.dev.log - the end of this log seemed to suggest that it was
a driver issue :

<<<  Section end 2014/05/13 22:24:00.475
<<<  [Exit status: FAILURE(0x00001a2d)]
But I'm not really sure how to progress troubleshooting this.

Hi
Just to confirm, AVG only needed to be "disabled until reboot" to install the KB. It was obviously preventing some file operations that were required during the initial install phase.
Thanks very much to Susan for her help with this.
