How to know if a virus is for real?


I used CIS to check an appplication I downloaded from the Net, and it says one of the EXEs is supposed to be infected with a virus “Application.Win32.HackTool.dUP2.~BAAZ@779020”.

Generally speaking, how do we know if this is a real virus or a false positive?

Thank you.
