Windows might be indexing your hard drive… There are many programs that could be using your idle time to do things. Could you tell us what is running? With that info we might help find out the answer.
You may try to open the \data\avast4.ini file and in the [Common] section, change the item Database=ODBC to Database=XML. This could prevent the Microsoft Jet drivers from accessing the database… does it have any (positive) effect?
