Detects instances where the DllHost.exe process writes new executable files (e.g., .exe, .dll) or script files (e.g., .ps1, .vbs) to common staging locations such as C:\Users\Public, C:\Windows\Temp, or C:\ProgramData. This behavior is indicative of potential malware delivery or stage-two payload execution.
