[Closed] Warning! Spyware detected on your computer

Hello,
Unfortunately I have recently ran into an issue where my background is changed to a screen that states "Warning! Spyware detected on your computer" then Windows XP antivirus started running all on its own. I couldn't get it to stop, then it just went away and was in my start menu, when I went to click on it I was informed that the file could not be located. Anyhow, below is the log that I have. Please help.
