Hi Thorsten,
and wouldn't suspect that it is doing that.
Is there some code path I'd trace down to confirm it's actually the
virusscanner causing the rename? Where in the code path would the tmp-file
be generated?
I would first try to use Process Monitor to see activity in the file
system, one time with and the other time without Avast or in the
latter case at least with your working copy excluded for Avast. The
MoveFileEx error should be easy to find using ERROR_FILE_NOT_FOUND and
from that point you "just" need to scroll upwards to see if files are
renamed by Avast or such.
Avast will surely not modify Subversions code, but hook Windows
functions instead and that may be hard to debug. I found Process
Monitor really helpful in such cases, that's what it's designed for.

Should have thought about using process monitor earlier... Thanks for
the hint.
However, I'm not getting much out there. Here's the summary from what I
see in process manager from the svn-BDF57639 temp file and the
corresponding trzBF17.tmp-file which in-deed is created by Avast.
The problem is I don't see where the svn-BDF57639-file would be renamed
or deleted.
I'd gladly send the log captured with Process Monitor just to make sure
I didn't overlook anything.
Quick sum-up of the log:
TortoiseSVN creates the file: .svn\tmp\svn-BDF57639 (SUCCESS) - Generic
Read/Write access - create
[...]
TortoiseSVN reads the file contest of the problematic exe file:
print_options.exe
[...]
TortoiseSVN writes the contest of that file excluding the final junk to
svn-BDF57639
TortoiseSVN reads the file contents of the problematic
print_options.exe-file again (EOF)
[...]
TortoiseSVN writes the last junk of the svn-BDF57639 file and closes the
file
[...]
Avast creates file access to svn-BDF57639 - Read Attributes/Synchronize,

[...]
