Trojan Horse has hijacked my Administrator Account

[Guest]

My daughter brought her computer home from college and said that she couldn't get into Windows Explorer. I scanned her hard drive with Norton Anti-virus (which was installed an active on her PC) and it found this file, JS[1].JS which it identified as a Trojan Horse virus. It then quarantined the file but the damage had already been done. Here are the problems it caused:
It captured my user account and changed the password.
It captured the Administrator account and changed the password.
It prevents the user to get into Windows Explorer, the Control Panel, and any other function that would let you view/change/delete files.
I can start the computer in "Safe Mode" which allows me to get into Windows Explorer and the Control Panel but when I go to the UserAccounts, the Administrator account is not displayed so I cannot change the Administrator password. Has anyone heard of this or have any ideas how to resolve the problem?
