cannot get past the windows xp home logon window

I ran spybot to remove a virus from my wife’s computer. It deleted most infected files but there was one that required the computer be restarted to delete it. I shut down the computer and restarted it. The computer presents a window that asks you to click on either “administrator” or “her name”. When I click on either of those the computer message says “loading personal settings” then immediately says “logging off”. This occurs when I start up the computer in normal and safe modes. What can I do to get past this screen?
