Actually our NAI product is detecting the password protected ZIPs =
themselves as viruses.

How does it decompress it without the password? Are they running a
cracking program to get the password so it can scan the archive?
I am using MailSecurity at another office and see nothing in settings
about this feature. Is it just something they say it does?=3D3D3D20

Blocking the specific filename attachments that Bagle and it's variants
use. These are documented by SARC and others. This lets me accepts
legit .ZIPs but not the virus. This is a short term option as I expect,
very soon, a variant (or new virus) that randomly generates encrypted
.ZIPs.=3D3D3D3D3D20
Some people on Focus-VIRUS mailing list are blocking attachment under a
certain size. Others block .ZIP entirely. The only methods are
filtering methods. No AV scanning products can pick up the virus itself
inside a password protected ZIP. The AV companies need to come up with
something quick! =3D3D3D3D3D20

Just wondering what others are doing to combat the latest BAGLE worm.
=3D3D3D3D3D3D3D It's password protected so standard AV won't scan into =
it.
=3D3D =3D3D3D How =3D3D3D3D is =3D3D3D3D3D3D3D everyone else handling =
delivery =3D
of .zip
files =3D3D now?
We're using the Trend Micro AV suite.
Do you think the latest password protected BAGLE worm has caused the =3D
=3D3D3D
=3D3D3D3D3D =3D3D3D3D3D3D3D demise of password protected .zip files?
My immediate opinion in the matter is that password protected .zip files
=3D3D3D3D3D3D3D will now be treated with the same delivery restrictions =
=3D
that
=3D3D =3D3D3D the .exe, =3D3D3D3D3D3D3D .scr, .pif, .vbs have come under =

I'm not
