Ruth , you need to be more specific about which "trojan" you have. Your post looks like a reply to a thread but it is all by itself so It's pretty hard to determine exactly what you problem is. Please give us some more info.
I am having the same problem getting rid of my 'trojan' virus. I've done just about everything I can think of to be rid of it. I ran AVG, turned system restore on and off, rebooted, etc., and to no avail!
I could use all the hlep I can get w/this annoying problem! Hope to hear from someone soon w/a guaranteeing remedy!
Take care and have a great holiday!
