Dang... First Howard Stern gets removed from some radio stations, now can't
use zips anymore... Sounds like an end of an era.

Exactly...Antigen has been catching Bagle.J here without a problem, but I
suspect that if I were counting on its normal ability to remove pif or exe
files from inside the Bagle.J zip files, then I'd be disappointed. I've gone
to blocking all zips, just because so many of the new viruses are using
them, and the time when you're really vulnerable is when the first wave
comes ashore, before the scanners have been updated.

They probably added a signature for some of the bytes of the
encrypted/zipped virus (as well as different signatures for the expanded
version).  The whole anti-virus scanning thing works on finding a unique
pattern of data within the virus.

A lot of discussion has been going on here on our campus with the theme that
password encrypted files can't be scanned.  So why are Bagle.H variants
being caught by ScanMail 6.2 for Exchange then?  Are they using a heuristic
to catch this instead of finding the actual virus pattern in the file
itself?

I just sent out an email to our users stating that for the forseeable
future, all zip files will be blocked.  That's gonna be a PITA. People have
really come to rely zipping files. (Although why someone would zip a 500K
Word doc down to 350K is beyond me.)

I manually downloaded and updated both the engine as well as the new pattern
that has not been released yet.  I guess scanmail cannot scan password
encrypted attachments so back to blocking the Zips.  Sophos does not scan
password encrypted either.

Are you sure about the engine?  Their sites says 6.810.  We got a couple of
the bagle.j come through.  Thankfully, Trend's desktop AV caught them.

I noticed that Trend has a new engine out there 6.860 and the manual update
does not update to that version.  It looks as if the new BAGEL32.J variant
got through on our system and I'm wondering if that engine is required to
catch it?
