Has any one seen this yet. I saw two win 8 laptops today do the same thing. When you click internet explore (on desktop,program menu or straight from the exe) IE starts to open but the closes and a download window appears prompting to save or open random files. These files names are random names and change each time. If you ignore and close app and start again it does the same again but now there are two files. It is very odd. Chrome works fine. Searched web but can't find any ideas.

Any advice would be welcome.
