random processes winXXXXX.exe spawning and listening

Hello,
I have WindowsXP SP3 (should be up to date).
For many months, my system is plagued with some malware.
Every 5 minutes or so, two or three files are created in my windows profile temp folder with random names beginning with win followed by 4 to 6 random alpha characters followed by .exe they all run as processes and all make some TCP/IP connection (seen with TCPview)
It is a very annoying piece of malware. I wrote a short java program to search the temp directory for the files when they are created and terminate the processes in realtime as they are spawned.

I have gone through the cleaning procedure described in the readme first.
It has not gotten rid of this. Thank you in advance if anyone has any info
about a similar situation and some possible solutions.

I did not find the TDSSserv.sys that you described.

Here is the combofix log..
