How does one handle a false positive?  One of the dlls in my Asus Bios update program (C:\Program Files\ASUS\AsusUpdate\BS_DEF.DLL) was considered a heuristic trojan.  Since I do not use this Asus program, I uninstalled the program after losing this dll to Bit Defender.  I will need to know this in future cases when a program that I do use is affected.
