.zip is the must importent issue.

the Zip is the key point in this Perfect demo by http-equiv .

you can do more cool things with Jscript like getting Windows User Name 
(via document.location) or run even regular EXE (TIF Enumeration).

becouse the zip temp file run without  Security Zone Check.

We are delighted to learn that the original self-executing html file, 
from June 1 2002 is now fixed with the most current of the many 
patches for the Internet Explorer series of browsers. See:

Regrettably.

The following file is an html file comprising both scripting and an 
executable [*.exe]. 

We inject scripting and an executable into the html file which is 
designed to point back to the executable in the html file and execute 
it. Provided the html file is an html file, Internet Explorer 5.5 and 
6.0 will execute it. 

Because it is an html file proper, Internet Explorer opens it. The 
scripting inside is then parsed and fired. That scripting is pointing 
back to the same executable file with our original codebase object 
from the year 2000 and because it is a self-executing html file, it 
executes ! 

Tested IE5.5 and IE6. Fully self-contained harmless *.exe:

Be aware of html files out there.
