Has my computer been hijacked?

How can I tell if my computer is being hijacked? I received back an auto response from a persons email box yet I never sent an e-mail to this person. They didn't send back the original e-mail only the auto-response. What worries me is that the subject line was selling pills (New product! Cial1s S0ft Tabs)

How can I tell if my computer has been hacked, how they did it, and most importantly how do I clean them out.

I use Norton Internet security with their firewall. I scanned with Norton, Search & Destroy and Ad Adware and turned up nothing.
I have attached below my hjt log.

Thanks for your help.
Jay
