d4k7b3a4 service ... have not yet found any information on this one either.  
Suggest you try at least two of these three, free virus scanners, as no one scanner can guarantee finding & fixing everything.  The AVG (grisoft) is particularly good:

I have runn all of these and they did find the installation for the Battlefield 2 Mod called nations at war was a Trojan. The Log still shows this service starting but not showing up in any of the utilities as a process.

Unless I find out what it is by this weekend I will reinstall windows.

I have been very carefull and lucky so far 2 years on this installation with out an infection till now. Without anything more than my firewall.

BTW this is the 1st time I let my gaurd down and did not scan the file (with another PC) before running it.

Thank you.

Our two posts obviously crossed !    Ok, thanks for the feedback.
   
If you believe it's a Trojan, you could scan with this online Trojan scanner "a-squared Free", which is specialized in Trojans & Dialers removal.  
But i would highly recommend regularly using a good virus scanner such as those listed above.  It is becoming more and more essential:
