I have a Barracuda 600 if you want to test, too.

Well, I printed the report (should've kept a digital one!) and the
spyware scantool from the Web-Filter appliance is clearly stating otherwise! I'm
gonna rescan my laptop tonight, and post a follow-up
tomorrow...

I
received a response about the false positive issue. According
to
Barracuda, it shouldn't be possible.
Their response
follows:
--------
Gerald,
We investigated your claim and found
that our Web Filter could not be
blocking the dll as
described. Please see the attached explanation from
one of our
Spyware engineers.
We appreciate your feedback and please feel free to
contact me directly
if you have any additional questions.
Thanks,
Sean

wireshark is the successor to
ethereal.
We don't have an sbus.dll in our spyware database.
In
any case, we don't match on file names - we match on MD5 hashes
of
files.
Our definition for Adware.Toolbar.ILookup.Sbus has no
associated files.
It only triggers on outboud traffic to toolbar.searchbus.com.
If the
customer is seeing a block message (ie, a message in their
browser) with
Adware.Toolbar.ILookup.Sbus on it, that would be... odd,
unless they were
navigating to that url.
If the customer is seeing infection activity
in their WebFilter UI -
that is not file related. The WebFilter
only cares about traffic. An
entry on the infection activity tab
that reads
Adware.Toolbar.ILookup.Sbus should be the result of outbound
traffic to
toolbar.searchbus.com. If
there is doubt about that I can usually
verify it by looking at the
WebFilter through the support tunnel. It's
best to coordinate
something like that with someone on the WebFilter
support
team.

Message Subject: Wireshark sbus.dll
false positive?
I've received a couple of reports from users that the
Barracuda Web
Filter has been triggering a false positives for each release
of
[url="" href="http://www.wireshark.org/]Wireshark[/url">
http://www.wireshark.org/]Wireshark[/url]. Wireshark's
S-Bus
plugin is named "sbus.dll", and the Web Filter apparently thinks this
is
the ILookup.Sbus worm. One such report can be found
here:

[/url]
Can
someone at Barracuda confirm and fix
this?
