Wireless Network Intruder? Really need help!

Hello:

I think that my home wireless network is being monitored. If so it's being professionally, albeit illegally, done. I have just enough computer knowledge to have completely lost my mind trying to keep them out without really accomplishing anything. I have three laptops running XP, Vista, and Win 7 respectively, an iPhone; as well as a d-link DIR-655 Extreme N Router, and Norton Security Suite 2010. The intruders have only been noticeable to me for a few months; but could perhaps have been going on for a year or more.

I think that the best strategy eventually is to reinstall the operating systems, reload everything, then do whatever I have to do to secure the network as much as possible. However, there is a now a significant time element, so unless they are using extremely sophisticated software-which may be the case-it imay be faster to try to work with what I have. In addition, if I can salvage even the slightest bit of evidence of monitoring and/or the source, that would be tremendous.

What I have done now is dismantle the entire network and am hardwiring each computer to the modem and trying to work through each (or even one clean one would be a great help at this point). This is my first attempt w/ an emachine E725 and Win 7 home. I followed all of the diections in the "Read and Run Me First" section, and at one point Norton removed a program called Bloodhound.exploit.281, and the scans removed some other files (thank you, MajorGeeks!).

I have attached the logs I ran. I couldn't figure out how to upload the Malwarebyte's and SuperAntiSpy text logs from notepad, but I looked at them and there were no problems found. I also tried combofix, but somehow it turned into a Fedex site trying to run an Active X, so I skipped it as instructed.

If anyone could help, you can't imagine the number of lives that would be improved.

Thank you!
