I'd like to say 'amen' to this.  There are reports on the AVIEN list 
that several very experienced AV researchers have managed to 
accidentally run this exploit while examining it.  One reports spending 
4 hours cleaning up his system afterwards.

Be very careful with this one and if you must play with it ;) then do it 
in a VM!
