Hmm, I added the 
http://download.opensuse.org/repositories/home:andavis/openSUSE_11.0 
repository then installed dazuko-2.3.6 and dazuko-kmp-pae-2.3.6 without 
any warnings about unresolved symbols.

I have heard from another person about this problem ( see 
https://bugzilla.novell.com/show_bug.cgi?id=401920 ).  It appears that 
there is some change in the dazuko 2.3.6 interface which is causing 
problems for AntiVir.  As noted in the bug, this version of dazuko does 
seem to work fine with clamav.  Also, I have run the dazuko tests on 
2.3.6 and those seem to work fine as well.

So I think the main question is whether Avira AntiVir supports dazuko 
2.3.6 with redirfs.  My understanding is that Avira has done some 
testing w/ dazuko 2.3.6 but I don't know their official position on it.  
I believe Avira is also looking at supporting dazukoFS so it may be that 
they decide to concentrate their testing efforts there instead of on 
dazuko-2.3.6.  Have you contacted Avira about whether they support 
dazuko-2.3.6?

In the meantime, I will download antivir and duplicate this problem to 
see if I can tell what is happening.
