heres your fix for this problem.
This kick is caused by a rootkit application running while playing on PunkBuster enabled servers. The name of the file is called oreans32.sys and it is located in C:\WINDOWS\System32\Drivers\ of your computer. Deleting that file and rebooting will allow you to play again. You may need to disable system restore if the file keeps returning.
Slow down there turbo B) ... oreans32.sys can be used as part of several trojans/root-kits, but it is also used by other legitimate programs as well; Prey (the game) for example.
A quick "Google" on the filename will return a boat-load of results that discuss this in more detail; unfortunately I've not found any fool-proof way to determine whether or not oreans32.sys is legit or part of a trojan short of deleting/renaming it and waiting for one of your legit programs to break.
Now - having said that; how did you go about determining that this file was the problem and have you tested the "fix"?
