ZiChatBot Dropper Deletes unicode.py and terminate.dll

Detects the Python wrapper and native dropper deleting their own unicode.py and terminate.dll components after the payload has been unpacked. The rule specifically looks for file deletion events where the target file name matches 'unicode.py' or 'terminate.dll' within common application data directories (site-packages, dist-packages, AppData, Temp) and the command line contains deletion-related keywords.
