bitcoinity.org tried downloading something onto android

[accord01]

I was browsing bitcoinity.org and viewing its charts on my cellphone.  And then few hours later, it tried to download the following file onto my phone:

markets_mtgox_USD...  This kind of worries me because I never authorized a download and there was never a download link on the site.  Since I log into online banking and other stuff on my phone, this could cause some trouble if it is spyware.
