1. Disconnect the box from the network.
2. No, really, disconnect the box from the network.
3. Get a copy of this: http://www.chkrootkit.org/
4. Build it on a known clean box
5. Copy the binaries to your hacked box
6. run them and see what they say.
7. Reinstall your hacked box. Don't bother trying to repair it you can
_never_ be sure you got it all.
