Javascript question

I know lots of you guys who play eqemu are javascript masters so I want to ask a question.

I play Diablo II from time to time just to really scam ppl's items (I know its wrong, but its fun!)

I got a program that can AUTOMATICALLY take control of your mouse and make you drop all your inventory all over the place and freeze up ur character allowing the other person in game to take it all and get away with it!

Problem, people dont fall for the old Hey download this and its a hack to give u god mode (example).

Therefore I know through javascript it is possible to load in .exe programs just by visiting the webpage (due to porno webpages always giving u dialers just by visiting their pages)

I want it to download in the little progress bar while the page is loading, then cover it up with a javascript progress bar blocker (shows any text you want, animated too, intead of showing what its downloading!)

Think someone could pull some information out for me? I already searched with google and had no such luck.

I will cut profits 50/50 with you if you have Diablo II also....

{Summary}- Basically what im trying to say is.... is it possible to load and execute a .exe file in the background of a webpage. If so show me the javascript for it.
