computer virus

Well my computer crashed due to an email that I thought was from my friend Deb but was not. I've gotten it cleaned and have reinstalled almost everything but am stuck on email, I can receive it but not send it. It is frustrating to spend hours and know I am missing something probably very simple but I just don't see it. I may cave and call the tech guys to come fix it but I will spend alittle more time on it. Thank God for the external hardrive all my pics, ripped books, music etc is secure, good job Dave on that one. Burning man looked incredible I bet you both had a great time.
