So guys, I've heard lots of people saying, "Help, my anti-virus is blocking gunz, is freestyle gunz a virus", and no it's not, trust me, your AVG anti-virus is acting up because it had taught fgunz was threat. heres a tutorial i guess, this will, maybe help.
l. Open Your Avast
ll. Click Real Time Shield
lll. Press the stop button.
lV. It will ask you how long, press stop permanently,
(Don't worry you can always start it up again)
V. Closed it and play.
P.S If you wan't it back just click the Start button, it will allow your shield again.
I guess that's it, please pm me if you're still having problems :].
