It's called ThePiratePatch and unblocks thepiratebay.se/org on your system. It patches your hosts file with a reverse proxy IP of TPB. It's completely harmless and even better, it's completely legal. I have implemented a backup system so you can even restore it!
There is no need of proxies, new domains, new ip's, VPNs. Just browse the url again.
Be sure you run it as Administrator, because we are editing your Windows files.
