Detects the loading of the 'user32.dll' library into a process named 'firefox.exe' where the process is either unsigned or executing from a suspicious location like 'ProgramData'. This pattern is consistent with the behavior of BabylonRAT, which masquerades as the Firefox browser to perform keylogging by hooking system APIs.
