An update for those having some of the same problems:
-
Converting filesystem from FAT32 to NTFS fixed the hanging at shutdown issue with 6.0
-
Converting filesystem to NTFS also fixed the continunous scanning of “avastUI.exe”
-
The long delay when starting something using the MS IntelliType keyboard software is due
to IntelleType checking all programs it knows about (it stores all programs ever started
on the system). This triggers avast! scanning of those programs, and the longer the list
the longer it takes the first time you start somthing from and IntelliType key.
BUT: I have found a way to help on this. It’s a bit “naughty” but it works 
First you need a regsitry file “itype.reg”
Windows Registry Editor Version 5.00
[-HKEY_CURRENT_USER\Software\Microsoft\IntelliType Pro\AppSpecific]
This will delete the list of programs IntelliType stores to prevent them beeing scanned
The you need a batch file to replace just starting “itype.exe”.
If you start this “itype.bat” instead it will flush the list and then start “itype.exe”
@regedit /s itype.reg
@start itype.exe
