WARNING! The method I describe is DANGEROUS but it works well if you try it as soon as you get hijacked. For example, I've been hit by "your search" and while my spyapps find it, as soon as you reboot it comes back. Using my tips is the only way I've been able to gid rid of it.
If your boss is using WinXP you might want to try "System Restore".
Good luck!
