Norton Insight issue

hi

I have a problem with norton insight. I downloaded rapidshare manager from their website (its a legitimate programme)

 

The app can be download by going here :  https://rapidshare.com/#tools_rsm and click download for windows

 

When i download this insight auto delete this exe (please refer this screenshot : http://i.imgur.com/xtOvWLa.jpg) i contacted rapidshare reg this and they asked me to contact norton since this has nothing to do with them.

 

Please assist

Sam
