	r  5.5 and6.0 Part III

How is this binary converted to the array in the source and then converted
back to a binary???
Anybody have information on how this is done?  

This makes me very worried!  This could bypass all the antivirus filters
that remove executables!

Has the Win2kSP4/IE6.0 combination been confirmed as immune to this?
