I was warned on a Library's computer that the following sites may harm the computer:
http://zeldaclassic.armageddongames.net/what.php
http://www.zeldaclassic.com/what.php
http://www.zeldaclassic.com/downloads.php
http://www.zeldaclassic.armageddongames.net/what.php
http://www.zeldaclassic.armageddongames.net/downloads.php
http://zeldaclassic.armageddongames.net/what.php
Maybe not just the website but Zelda Classic itself.
I highly recommend you go onto

and get a review(s) of your site(s) and Zelda Classic downloads themselves.
