Can't login

I'm a new user for Windows Vista and having a difficult time with a login
issue. Someone tried to install McAfee anti Virus on a friends computer and
now everytime they login, it says disconnecting from the network and
restarts. Once it comes back with the login screen again, it say handle is
incorrect. I'm just remembering this off the top of my head but I can't do
anything! I can switch accounts but no luck there. I typed in administrator
as the user name and no password because there isn't one and nothing....is
there a way to over ride this and just get to the home startup screen.

Are you sure that you did not "borrow" someone's computer, mmmm?
