I do hope there are loud alarm bells ringing where you are? This is extremely suspicious and you should investigate to make sure your machine has not been compromised.
The future appears to be RHEL or Debian. I think I'm going Debian.

CentOS 5 and 6 are deadest, do not use them.

Thank for alerting me, yes, I did re-scan the whole system for malware, virus..., upgrade security level also, but in newbie perspectives.TrevorH wrote:I do hope there are loud alarm bells ringing where you are?

If you can share some techniques preventing virus, hacking.. I really appreciate.

Backup and re-install.
You can't trust any of the binaries on the system, so you can't use them to check the system.

To keep your system secure:
1. Make sure it is kept up to date with security-related updates.
2. Protect any logins against dictionary attacks with fail2ban or something equivalent. ssh, imap, smtp/sasl, etc..
3. Review the privilege level of any daemons. Do they need to run as root, or can they run as an unprivileged user? For CentOS provided packages, the default configuration should be OK in this respect, but anything that did not come from the CentOS repositories should get extra scrutiny.
4. Review what daemons you have running, especially with exposed ports. Do you need to run them? Do they need to listen on any IP addresses other than 127.0.0.1?
5. Check your mysql configuration. The default CentOS installation leaves the root password blank (or, it did last time I installed mysqld/mysql-server on a new system).
6. Others ....?
