Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

Ok, first off the webpage gives me this:
The requested URL /img/noprocess.png was not found on this server.
Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request. "
Secondly, are you user "500"? There appears to be a lot of stuff running, but it all has a name. Are you intentionally running "snort"? It is for sniffing packets on a network. There's a few other programs I don't recognize(and am Very suspicious of):
p0f -d -o /var/lo #something that tampers with log files?
login -- xconspir
I'm have no idea if you have a trojan or not, but in my "unexperienced" opinion, it appears so.
Belongs to rpc/portmap/nfs. Provides shutdown/reboot notification for RPC (see it's manpage for more info). You should shutoff portmap and nfs if you are not using them.
network interface daemon (see it's man page)
multicast Doman Name Service Responder
p0f -d -o /var/lo #something that tampers with log files? p0f is a passive OS fingerprinter
Hardware Abstraction Layer daemon, a hardware management daemon that utilizes dbus
login -- xconspir
A login session
In general, there doesn't seem to be anything malicious as long as snort and p0f can be accounted for. Though it's probably a wise move to turn off some of the extra daemons and services. If you are still paranoid, take a look at chkrootkit, samhain, or rootkit hunter.
Out of an unrelated curiousity, what distro/version was the process list from (has to do with the presence of the login process).
