[Samba] Virus checker leaving "chmod of" files in samba log

[Sullivan, James (NIH/CIT)]

Hi all,

I am running a Samba 3.0.0-14.3E server on a RedHat Enterprise WS3.
Here's the problem:
When I am connected from my PC (Windows 2000) and run the 
MacAffee v4.5.1 virus scanner on the connected share, I see the following
in the Samba log file (debug level=2) for what appears to be each file in
the share:

[2004/07/20 13:02:51, 2] smbd/open.c:open_file(250)
  sullivan opened file media/._media1.pov read=Yes write=No (numopen=1)
[2004/07/20 13:02:51, 2] smbd/close.c:close_normal_file(228)
  sullivan closed file media/._media1.pov (numopen=0) 
[2004/07/20 13:02:51, 2] smbd/open.c:open_file(250)

  sullivan closed file media/._media1.pov (numopen=0) 
[2004/07/20 13:02:51, 2] smbd/open.c:open_file(250)

Note the 
"chmod of media/._media1.pov failed (Operation not permitted)" 
line.
Does anyone know what the virus scanner is trying to do?
