Use my trainer, click AntiClick on and do as it says and u won't be kicked again with its little trick.
This is public, private stops u from getting kick full stop. Private might not work though.
Private is also inclueded free( this site is to good for hacks, but don't leach this hack on to other sites)
make sure u launch cod4 then minimise to turn them on
if this does not work for u then all i can say is tough luck
Pls believe me with this, this 99.99% antivirus free, the other 1% is a possible chance
