Can't Navigate due to Spyware on desktop

I thought my computer had a virus but now understand it is spyware and malware. The only way I can navigate the internet is by typing in the specific address into the navigation bar. I can't use search engines because they take me other places. Just today, my Yahoo! email acted up by sending me some weird place when I clicked on the email. I had to use my back button to get back to the email.

Here is my log file. I have no idea what to do with this. I appreciate any help you can provide me.
