Do I have spyware or not?

I've been noticing internet slowdown lately. I regularly scan for spyware, but the Level 2 tech at Adelphia claims that he can see that my modem is getting "hit" by something at a great rate. He claims that I have spyware. I've since scanned with Adaware, Spybot, Microsoft Defender, Ewido, Panda online and Trend Micro, but the tech still claims to see evidence of spyware on my system. I can't believe that nothing would find the problem, but he seems to be really certain about my infection. Please look at my Hijack This log and let me know if I'm infected or not. Thanks in advance!
