Are you asking because you're getting kicked from servers for NOT having it enabled?
The punkbuster button is usually located in the lower right-hand corner of the Ubi.com login screen. If it's not there, it's because of a common bug. I fixed it by downloading someone else's PB folder from an earlier thread on these forums (search "Punkbuster"), although it might be fixed by going to evenbalance.org and downloading the most recent pb.exe file for SC2.
