There is nothing that OS X.x does that would make a virus safe for a windows user, so if you pass along a virus it won't infect you but it will still be contagious to a vulnerable windows machine. You have in fact become a carrier of the virus enabling it continue it's work elsewhere, if you ran antivirus on your machine you would strip the file out of the message and stop that particular branch of it. All in all if it is a virus that is particularly nasty you won't affect the big picture but you may help out a friend, relative or acquaintance by running anti virus software.
