Can I use an anti trojan program as well as norton

Can I use an anti trojan program like ewido as well as an anti virus program like norton. I have heard a lot of people recommending ewido for preventing trojans and wondered if an anti trojan and anti virus are different things and if they can be used together

Thanks for the replies, I will be getting myself a copy of ewido tonight
