Security log full, why?

I am getting warnings on my DELL Dimension desktop running XP SP2 when
I log on using RDP. The warning is about the security log being full
and that an administrator should fix it...

After I use Event Viewer to clear all log entries it only takes a
short time until it fills up with new entries again. Almost all of
them are titled "Failure Audit". The text in the listbox when I open
one of these is:

The Windows Firewall has detected an application listening for
incoming traffic.

Name: -
Path: C:\WINDOWS\system32\svchost.exe
Process identifier: 1416
User account: SYSTEM
User domain: NT AUTHORITY
Service: Yes
RPC server: No
IP version: IPv4
IP protocol: UDP
Port number: 1219
Allowed: No
User notified: No

If I use Taskmanager to find svchost.exe I find no less than 7 of
them. One of these stands out among the others because it has used
lots of CPU time (right now 0:05:52, whereas all others are below a
minute) and I/O Read Bytes is over 2.2 Gbytes and counting. This one
also has the PID mentioned in the event log.

When I use ProcessExplorer from SysInternals I get more info:
"Generic Host Process for Win32 Services"
Command line of process: C:\WINDOWS\System32\svchost.exe -k netsvcs
If I look in the Services tab I find no less than 30 entries...

How can I find out what is causing this audit failure and why?
And how can I stop it from doing whatever it is doing?

BTW: "Tasklist /SVC" gives the following output related to svchost:

Svchost.exe is a general purpose program which can be used for quite a few
different processes. It is not unusual to find 7 different processes
executing this program.

If I had your problem, the first thing I would do is to perforam a thorough
malware test. It does seem likely that you have a bad case of infestation.

The second thing I would do is dependent on what the results of the first
test are.
