Hi Dan,

I'm running 10.0.1.13.  But, the signatures should be the same as yours.
Not sure if the version matters all that much.

Hi Dan,

I setup a test box with Norton and surfed to sites where I could get the
*.wmf thing so I could see what it does.  And Norton did not catch this.
Well at least with the desktop version I ran. good thing I just closed
down
my virtual pc without saving anything!  I noticed that on sites that use
this they use this class ID 2D360201-FFF5-11d1-8D03-00A0C959BC0A and
that
belongs to the :
Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\DHTMLSafe.DHTMLSafe]
@="DHTML Edit Control Safe for Scripting for IE5"

[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\DHTMLSafe.DHTMLSafe\CLSID]
@="{2D360201-FFF5-11d1-8D03-00A0C959BC0A}"

[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\DHTMLSafe.DHTMLSafe\CurVer]
@="DHTMLSafe.DHTMLSafe.1"


So, I'm going to do more research on this myself

Thank you,

Joseph

I searched for about an hour last night about how to "block" this, but
only came up with a couple of solutions.  One is a patch written by a
third-party that you install on your computer, and the other is to
unregister some DLLs to disable that feature entirely.  Both of these
seemed to be very time-consuming methods, and with 1200 computers to
update in a little over 24 hours it didn't seem worth it.  

Symantec appears to be confident that their real-time protection with
current definitions will vastly reduce that threat, so I think we'll
just ride out the storm until the "official" patch is released.  Since
all workstations are behind the ISA server, Internet access to a
compromised machine is difficult at best.

Did anyone ever post an answer? I'm curious about this "wmf block".
