My computer is sending out email viruses?

[ppreheim]

I work at a high school teaching basic computer applications. Our schools computer tech (who I do not trust) came to me and informed me that this computer was sending out viruses through email even though email had never been set up on it. I have done all the steps in the "do this first thread". There were 5 hits in the panda scan that I will post along with the HJT. If I trusted the teach I would have him fix it but that would mean the computer would be out of my hands for about 6 months. With 36 kids a class and only 32 computers it is vital I get this one back online as soon as possible. Please help!
