Personally I wouldn’t check the avast log entries unless there is an error displayed to the screen as they as you have found aren’t very user friendly. They are of more use for fault finding by one of the analysts, etc.
The error 00000005 (error 5) is a windows error and it is “Access is denied.” There are many legitimate reasons why a file should be protected in this way, though I can’t see why the NT Uninstall entries should be.
There is nothing to be concerned about.
ok, thanks 
You’re welcome.
