Still haven't heard from Gary yet. If the malware is not a RootKit then we'll get that link posted here. If it is an RK, then we'll have to take this to a private thread to block RK writers from observing which tool and version is used to remove it. That's what it's come down to lately.
But if Gary ever contacts us, we'll have him provide you with any info you need.
Hope you understand ;)

As long as you can keep the malware blocked, post the log to the HijackThis Forum at AumHa:
We'll call in the "Experts" if need be and at least identify the malware, the risk from it, and who's hosting it.
I'll BCC this. Email me when you post the HJT log and please, provide us with the IPs, too.

Any ideas on how to trace this? I can't find anything in running processes
that isn't supposed to be there. Note that these calls are being made even
when nobody is logged on to the machine. They're averaging one per second.
Well, I hope Gary will provide the link to the HiJack This website in this newsgroup so that other users like me can see what potential malware is in the HiJack This log. Gary, if you do not want to post here then you know my email and please email me where you posted the Hijack This log and thanks in advance because I appreciate all you do for these newsgroups.
Sure, I fully understand and thank you for your consideration. I find the security aspect of computers fascinating. <grin>
