I keep having errors in named like "unexpected error" and "Bad or invalid
In the support forums I found that this could have something to do with a
virus scanner, and indeed when I unload Firebreak, the errors are gone.

Problem is, that every dns update requires me to unload Firebreak, and then
unload/reload named. This can be pretty annoying sometimes....

Is there any way to solve this, like exclude some files from the scanner or
anything like that?
I already tried to exclude SYS:\ETC\DNS and the files SYS:\named.run and
SYS:\nwDnsErr.run, but with no results.
