I ran Spybot in an older version, updated the database and then it failed after deleting some of the viruses it found. Apparently it affected the file that controls the User Logon.
I reboot it, and get the User logon screen. When I click on the icon for the user, it reads that it is installing the personal settings and then it shuts down and the message reads, saving settings and it logs off.
I go o safe mode and use last good settings...that doesn't work.
That does mean I can get to the command prompt but I don't knowm what to do after that to edit the registry.
