I use phpbb for my forums and have been very happy with it. You just need to be sure to have the latest patches installed, there were some bad security flaws for a while. Also there are some good tips in the phpbb formums for handling spam bots. I've implemented some of these and they are very effective, although I still get some spam registrations. I make them reply to a message before activaing the account though so usually they never get a chance to post becuase the email addresses they give are bogus.
