You can boot the system with one of the rescue CDs offered by various antivirus companies and see if that will remove the trojan so you can get into the computer. Or you can pull the hard drive and scan from a different computer. I don't normally like to do this since there is a chance of infecting the host machine. Another alternative is to create a Bart's PE with antivirus/antimalware plugins and boot the computer with it to try and remove the trojan.

Some rescue CDs:

Another alternative is to back up your data to an external hard drive by booting to the Bart's PE or a Linux Live CD such as Knoppix and then do a clean install/factory restore of the computer.

If you can't do the work yourself (and there is no shame in admitting this isn't your cup of tea), take the machine to a professional computer repair shop (not your local equivalent of BigComputerStore/GeekSquad).

Then how did you know you received a trojan when you first posted? In any case, if you have another user account with administrative privileges you can log into that account and change your original user account's password from the User Accounts applet in Control Panel. If you don't have another account like this set up or don't have the password to it, you'll need to log into the built-in Administrator account. In XP Home, boot the computer into Safe Mode. Do this by repeatedly tapping the F8 key as the computer is starting up. This will get you to the right menu. Navigate using your Up arrow key; the mouse will not work here. Once in Safe Mode, you will see the normally hidden Administrator account. The default password is a blank.

In XP Pro, you do not need to go into Safe Mode. At the Welcome Screen, do Ctrl-Alt-Del twice to get the classic Windows logon box. Type in "Administrator" and whatever password you assigned when you set up Windows. If you have XP Pro or Media Center and were using the built-in Administrator account for your regular work and it is therefore the only user account on the system, there are ways to change the password for that account to a blank. Microsoft doesn't permit us to tell you how in these forums. Their house, their rules. Use Google or ask a local computer tech (not a BigComputerStore/GeekSquad type of place).

The good thing is that you can beat this.  Just restart your computer into safe mode using the default "administrator" login user name with no password unless you created one during installation.  Once you click on restart, Press the F8 Key and at the menu go into safe mode with no networking (internet).  Log into the administrator account as mentioned above, then do these three things. 

1.  Disable the restore feature by right clicking my computer and clicking the advance tab and go to system restore and disable it.

2.  Click on My Computer and Right Click the C:\ Drive and  click the Cleanup Button under the pic and Check every box not checked and then OK.

3.  Lastly, Goto Control Panel and then User Accounts and Disable the simple logon feature and then apply.  close all windows and then restart the computer.

Finally, you will log into the "administrator" account again and download the microsoft security essentials suite from microsoft.com and run the scan.  It will update the software and then will ask to choose the scan.  Choose Full or Complete scan and this should repair the problem.  After the repair, restart the computer and login with your credentials and don't click on any pop ups offering antivirus, spyware, or malware protection.  Most are fake and if you did not want to go there, don't believe in a internet annointed one knowing what you want to do before you know you want to do it.  Thank You for your time.  Misterehead  COFFEE COMPUTER SERVICES
