BF4 I always get kicked by: PunkBuster

Check here to  get this fix out:
1) please go to http://battlelog.battlefield.com/bf4/gate/
2) Click on the Profile button in the top right corner of Battlelog and select Change Soldier.
3)  From here you should see a list of soldiers associated with that account, one of which will be Active and highlighted in green.
4) Click on the Active button next to one of the alternate soldiers and then attempt to access the Battlefield 4 Beta again.
5) If you still receives this issue ask them to repeat Step 3 for each of the soldiers associated with their account.
6) Please now allow origin and game from firewalls as an exception.

Make sure your anti-virus is not blocking punkbuster, also check windows firewall. 

Punkbuster has 2 services running in the background in order to check your PC for hacks or 3rd party programs influencing the game.

They are called:

PnkbstraA

In order to enable both do:

1. Press Windows button and R at the same time

2. enter "Services.msc"

3. Locate PnkBstraA on the list

4. Mark both and select "Start the service" on the left side.

4B. If already running restart it.

This should resolve your issue.
