Running further tests I found that a couple of files were missing, namely MFC110U.dll and MSVCR110.DLL. I have not exhaustively tested all features of AVG so there may be more files missing.  I then did a re-install of the new AVG2014, but this time did a REPAIR option install. Restarting the system and repeating my testing, all is now well. I am trying to pass this information back to AVG. As a background note, I conclude that the installation process is flawed, as it seems that the loading of the updated version is preceded by the unloading of the previous version, and I conclude that the missing files were removed by AVG.  The files are back in Windows/System32

So if your installation of the updated AVG2014 has strange symptoms, you may want to consider a REPAIR option install, to fix things up.

The AVG2014 maintenance update, I just received and installed  today from AVG, has a major flaw as far as reporting scan results for email attachments. It is reporting a negative/random number for the return code.  For users of my Virscan utility in Pegasus Mail, this causes an email message to be generated for every attachment that gets scanned by AVG2014.  Until the vendor fixes this problem, please update your copy of Virscan.ini to comment out the "Notify=" line by placing a semi-colon in column 1

I will let you know when this has been fixed.
