I believe that Zango can only be dl by agreeing to it's terms and conditions. Meaning someone on your cpu pry dl it. BTW Zango is primarily used for looking at adult sites/pictures I've come to know. I've had to deal with this many a time here at work. Go into your control panel, add/remove, and remove anything that says "zango" or anything that is pop-up or advertising related.
Zango is notorious for allowing multiple pop-ups, some that can crash your cpu if left alone. GL

and there isn't anything wrong with this site.
