My computer was recently infected with spyware.?

I've been able to resolve most of the problems, but a couple things are still giving me trouble. For example, when I click links on a Google search page, I get redirected to some bullshit advertising webpages. Also, I am unable to connect to liveupdate for Norton antivirus, though I'm unsure if this is related to the spyware infection. Below is an Hijack-This log of my computer. Any suggestions?
