Naw .. zip utilities expect text in the .ZIP comment.  They display it (using 
one text display method or another), no way for it to EXEC.
You _could_ possibly install an ANSI bomb in the comments .. but that would 
only catch the idiots that still have dangerous versions of ANSI drivers 
installed.
Now, there _are_ some self-extracting archives that could be hacked or 
infected, made to do 'orrible things during (or in lieu of) their user query 
and/or extraction .. but I never run a self-extracting archive anyway.  I 
always use the original archiving tool to view, test, and extract the 
mbers.
