Avast and Windows Log Errors

Per prior post, I am trying to determine if I have had a window of vulnerability on my machine. Today I have received three error log messages

AAVM - scanning error: x_AavmCheckFileDirectEx: avfilesScanReal of C:\Users\Arthur Coleman\AppData\Local\Hewlett-Packard\TouchSmart\Media\CLML\CLDB_iTunes_SUB_INFO.db failed, 00000005.
AAVM - scanning error: x_AavmCheckFileDirectEx: avfilesScanReal of C:\Users\Arthur Coleman\AppData\Local\Google\Quick Search Box\cache.db failed, 00000005.
AAVM - scanning error: x_AavmCheckFileDirectEx: avfilesScanReal of C:\Users\Arthur Coleman\AppData\Local\Temp~DF5B81.tmp failed, 00000005.

ANd then on 9/11
AAVM - scanning error: x_AavmCheckFileDirectEx: avfilesScanReal of C:\projects\thunderbird\Profiles\3abm9sb4.default\Mail\Local Folders\Inbox.msf failed, 00000005.

Can you help me understand what these error mean and if I should be concerned about them.

The error 5 is ‘Access Denied’ (file in use, not enough user rights etc.)
Are you running a limeted user?

I could be wrong but:

Seems file in use, not access rights limitations.
I won’t worry. It’s just verbose of the logs.
