Intrusion attempt by lightwon.info was blocked

Hi basically i opened up firefox onto my homepage which was bing and no script tab opened up. i closed that and clicked a few links on the bing home page which today were to do with the palm tree island in dubai and i was looking at the first link and basically norton popped up with an intrusion message which i have attached.

 

But basically I don't get why something like that would pop up from bing homepage as all it was doing was going to pictures etc all ofg the links were on the bing website except this one: http://www.myhotelindubai.com/wp-content/uploads/2011/03/Palm-Island-Dubai.jpg.

 

Has anyone heard of this? is it from the bing website or what? or is something that firefox has let through some how?

 

 

Sorry im rubbish at explaining, i tried searching and cannot find any information on lightwon.info :S does anyone know about it.

 

but yes basically has anyone heard of this like :S

 

Thanks sorry im rubbish at explaining.
