Clear of FUD: The threat is the same as before, one of the subcomponents
of existing exploits just has a new approach.

Hi All
Can anyone out there clear the FUD and speak to the less Web Savvy (like
me) - I set up up a quarantine system (although still with Internet
connectivity) to run the exe-cute-html but this didn't 'appear' to do
anything other than display the "JUNKWARE" text.
i.e. I downloaded the zip and extracted the html and then I
double-clicked on the html file so that IE(5.5) would run it.
So I presume it would be running the html from the MyComputer zone - but
I didn't get a dialog box or anything.
I'm mostly interested in whether this is a big risk to the company. I'm
willing to believe that users can be fooled into downloading html and
opening it locally (e.g. if they think that they are downloading a
useful report), but then, they can probably be fooled into downloading
an exe and running it... So am I simply looking at continued Security
Awareness briefings (or more draconian download restrictions) or is
there a greater exposure that I'm missing. 
I may have missed earlier parts of this thread so I hope I'm not going
over old ground.
Regards
Bis
