That makes not difference if you have AutoHotkey installed or not as it's a script that is complied to an exe and does not require AutoHotkey to be installed, it's self contained:
"The RAT delivery campaign starts from an AutoHotKey (AHK) compiled script," the researchers noted. "This is a standalone executable that contains the following: the AHK interpreter, the AHK script, and any files it has incorporated via the FileInstall command. In this campaign, the attackers incorporate malicious scripts/executables alongside a legitimate application to disguise their intentions."

It's the same as saying I won't to use Delphi or C++ or Lua or bat as they can be used to make viruses.
