Keen: Modding

Hi!
I want to try Commander Keen modding but Windows Defender detected malware on UNLZEXE and deleted it.
I want to know if it's a false alarm or not.
I downloaded UNLZEXE from here:
http://sourceforge.net/projects/cloneke ... p/download

It's a false alarm. UNLZEXE is a legitimate utility, but some antivirus programs get suspicious because it's designed to modify executable programs.

Alright. Thanks man! :)
