Unloading a minifilter driver by calling the FilterUnload which is the Win32 equivalent of FltUnloadFilter. It will call the minifilter's FilterUnloadCallback (PFLT_FILTER_UNLOAD_CALLBACK) routine.

I'm a bad person. I should have just fixed the script in the repo of the original author, but opted to steal the TweetDestroyer module instead and wrap it with updated code to support the twitter json (not csv) - thanks @koenrh !
from datetime import datetime
import json, os, twitter, io, time
string_input_with_date = "01/01/2018"
file_name = 'tweet.js'
