Multiple Avast! Modules loaded on system startup

I am using Avast 4.7 Home Edition on Windows 2000 Pro with SP4.

I found that the Avast program has 2 copies of some of the modules loaded in memory: aavm4h.dll, ahresws.dll, ashbase.dll and ashtask.dll plus a few others.

Is this normal or do I need to look into why this is happening? The Startup programs entries only show 1 instance of the program being started: ashdisp.exe.

I am concerened because all told these loaded modules are using over 2,000KB of memory.

How are you reading this? Which application do you use for this?
I mean, isn’t the same module that uses two different memory addresses?

I used the Win2K system management tool; here is a screenshot of the display I also to saved it to a text file in case you would like me to attach it.
