MalwareBytes Anti Malware will block your internet access to P2P.
It will also block some websites like Game Copy World.
Dont get me wrong, the program is great and I highly recommend you keep it aside for instances when your PC acts up due to malware or viruses.
That said, it is not enough to just exit out of the program or stop it.
It must be removed from your system in order to get Internet connection restored on LimeWire.
Hope that helps a few of you out that may have it installed....
