Back Door Agent

My son's computer is a mess and I am trying to clean it up. He has Windows 2000 and didn't do a good job keeping his virus software updated. I have gotten rid of everything but this Back Door agent.

I read that you could rename, drag it to the desktop, boot in safe mode and delete it. I can get the computer to boot in safe mode. I know the home page has been hijacked, but I can mess with it and get it back to google.

I don't know what to do. I can't get to any sites that have removal tools. When I search it goes back to a hijacked search page. When I run AVG, it calls it BackDoorAgent.B, but I can't get to the removal tool.

I thought about starting over, but I dont really want to reformat, etc... I need help, I have spent too much time on this and he is not happy without his computer.

Thanks.

Nancy
