If the system is local then boot from a Live CD like KNOPPIX or HELIX and please read and act on this first: Intruder Detection Checklist (CERT): http://www.cert.org/tech_tips/intrud...checklist.html
If the system is remote proceed with the checklist. Please post any results.

If your system was compromised then follow up here: Steps for Recovering from a UNIX or NT System Compromise (CERT): http://www.cert.org/tech_tips/root_compromise.html. Note you should not attempt to "recover" a compromised system but reinstall from scratch, harden and maintain properly.
