FreeBSD doesn't come with chrootkit. The one in the ports reports
so many false positives that it is practically useless. I wouldn't
depend on it to make any decision.

Having said this, if you're worried about system tampering, all you
really need to do is to grab an installation CD; backup /etc, and reinstall
the kernel, libraries and binaries, restore /etc and you're away.
