Actually, this happens to me sometimes on Torn. Often I'll find I've accidentally tried to save/download the webpage I'm currently on.
You have no idea how many times City.php, item.php, index.php etc has ended up in my download bar at the bottom of the page.
I don't think it's a virus from a forced download, I think you may have fatfingers like me and often click things without meaning to.
You know, I actually don't know what shortcut or what I've clicked to cause this. Just it happens almost daily.
EDIT: This actually happens on some other websites too. I'd love to know how I'm accidentally doing this, but I don't really care enough to find out for myself.
Proof, my download list from yesterday.
