Can't log in to PC - can't get out of safe mode

Yesterday my Symantec Antivirus software informed me that I had a Trojan
horse. There wer isntructions on how to remove, which I followed. 1. Turn
off System Restore, Go to CMD prompt, type msconfig, go to boot.ini, change
boot to boot in Safe Mode, restart computer. This is where I ran into a
problem. When I rebooted in safe mode, I usually get a CNTRL, ALT, DLT
screen where I need to enter username and password. I entered mine and I get
an error, I can't get in now. Also tried changing username to
"administrator" leaving password blank. Still can't get in. Also can't boot
in normal mode. Attempted to by hitting F8 on start up. Will not start in
Noraml mode. Will not start in last know good config, etc. Can't get out of
Safe Mode. Need help Please.

What exactly happens? What exactly do you see? For example, does it
reject the username or password?
