Avast seems fine but some log messages are odd

I have Avast Home installed on a Win 98 SE machine. Everything seems fine on scan and e-mail. However, I see the following messages in two of the supporting logs generated by AVAST. They bother me because they are repeatedly displayed. QUESTION: Is anything wrong and, if so, what should I do to fix it?
Here are the files and the repeating messages:

In the file AvCommEx.txt, the following two messages are repeated over and over (date varies)
Sun Jan 23 10:19:42 2005 (and other dates)
CreateConfigStructure: LoadLibrary Aavm4.dll failed: One of the library files needed to run this application cannot be found.
Sun Jan 23 10:19:42 2005 ThreadNotification: ThreadNotification failed: The system cannot find the file specified.

In WARNING.LOG, the following message appears over and over:
2/2/05 10:44:16 PM 1107402256 xxxx 4294427593 Function setifaceUpdatePackages() has failed. Return code is 0x000004C7, dwRes is 000004C7.

Rraberbach, nothing to worry that much. Verbose of logs.
Anyway, you can repair your installation and see if you get rid from them.

To Igor: for God, change the logs. All users get anxious and nervous about them. Maybe just a word: "Don't worry, everything is ok. CreateConfigStructure: LoadLibrary Aavm4.dll failed... etc.
