I have attached some of the IP's below.  I have ran antivirus, anti-spyware and rootkit detectors (sysinternals, and f-prot) all came up empty.  I had found one other person on the internet that seemed to have this problem, but no resolution. Any ideas?

I'd try using TDIMon
(http://www.sysinternals.com/Utilities/TdiMon.html) from SysInternals
to see what process is sending the packets and start from there.
