Suspicious Service Names, fear trojan

Hello,

I am posting from a different system than I am reporting on. I have taken the suspected infected PC off any internet connectivity, so please forgive that I have not followed the steps precisely.

Machine has AVG (updated 3/21) and Spybot S&D (updated 3/19) on it.
I saw router lights going furiously after starting Divx player (v6.7) yesterday.

That's when I unplugged the network cable and ran HiJackThis and found several "Unknown Owner" listings in the O23 Service section.

The only online posting I found was for SIST.exe on PREVX as potential malware but no further details.

All I hope to learn is what this is or was. I am already resolved that the system will have to be re-built.

Any responses would be greatly appreciated.

Here is the HiJackThis log:
