one example of how it can be dangerous is if you accidentally download a
program into your current directory with a name that matches a system
command, it will get executed instead of the system command.
this can be exploited by the nefarious to install a trojan, virus or
other nasty.
coupled with the average windows user's insistence in running with admin
rights & clicking anything is sight is one of the reasons that windows
has so much malware
