Windows XP Pro SP2

I made a big mistake and installed a program from fullsoftwaredownload.net
All the programs I downloaded were infected with trojan horses.
I uninstalled the program but now on start-up the following programs start :
Limewire
Morpheus
Sheharaza

Lime wire is installed in c:\program files\limewire
But I cannot see it - or the other two programs - in the Add/Delete list in the Control Panel, nor in the start-up list

How do I disable these three programs at start-up or - failing that - uninstall them

All advice gratefully received.

Regards

John
