Before you do the proper thing and flatten it and reinstall from trusted 
sources..ask yourself your real intrusion points.... if the computer was 
merely "on", "people" should be able to get on the box without

a.  a backdoor implanted on their first probably by your teenagers 
surfing and downloading free software
b.  a vulnerability in an installed program
c.  a port/or way on to that box (what ports were open inbound from the 
Internet)

I'm guessing your kids got nailed with malware/peer to peer trojans 
because they've been surfing places they shouldn't have.

If the kid had admin access and able to install anything.. 'that's how 
the critter got on the box.

When teenagers are in the house, either have them with non admin access 
or plan on nuking and paving a machine on a regular basis that's set up 
just for them.
