Wondering if someone can help me with a Win32/Zlob warning.

I have a program I wrote and one of the executables I built to go with it is systemdata.exe. This does nothing more than getenv("USERNAMES") then takes the username adds it to the query (along with date time and a directory address)and submits to the database to then be checked for security access of the user.

For some reason Windows defender keeps throwing up a message that my systemdata.exe is a Win32/Zlob Trojan.... Anyone ever ran into this?
