Hi guys, first off all  I want to say "Hallo" to evryone

And so I have a problem ; I hope I write into the right forum.

I recently got an U3 USB STick and now I want to write an autorun like feater into it.
I found out that with an Universal customizer I can put other programs into the U3.

I work on an Win XP xomputer wit Antoi Vir on it.

How would the best way to write such an autorun ?
Like a normal autroun with a batch file ?

And will my Anti Vir lock an autorun ?

I hope you can help me
