My published application is a virus?
I have recently created a small VB application for a friend of mine, I am using the publish feature included within Visual studio (it's the easiest way of updating it and having the updated version downloaded automatically) but when I download it, it downloads "setup.exe" 

Chrome and AV's seem to think this is a virus, why is this? I have made it a full trust application and signed it with a certificate and a key, but it still think's it's a virus, any ideas?
